presently used for VVIP aircrafts.

2.3 Role of Station in en-route Navigation:

The station provides a range of ground-based devices to assist en-route navigation. VOR is the main aid to

navigation, providing a radio signal that enables a pilot to take his bearing from a particular station; and co-

installed with it is usually a DME, by interrogating which he can compute his distance from that point. This

combination of VOR/DME is the ICAO standard short-range navigation and position fixing system. ATC

instructions are required by the pilots to fly a particular course or patterns and these are normally linked to

individual VOR 'radials' or positions. Outside controlled airspace the pilot can navigate independently with

reference to VOR/DME, which can also provide a reliable means of defining a predetermined approach to its

destination.

2.4 Organisational Structure:

2.4.1 At present the station is posted with three executives (including Officer-in-charge) and one

assistant. The three executives comprises of one each from Senior Manager, Manager and

Junior Executive level.

2.5 Accountability:

2.5.1 The officer-in-charge, Aeronautical Communication Station, Airports Authority of India is responsible

for ensuring the safe, efficient and secure provision of the station facilities and also accountable for all

ongoing operational/administrative deliberations at the station.

2.5.2 The activities required to execute these responsibilities include:

Establishment and Management of an independent Aeronautical Station.

Implementation of ICAO Norms.

Promulgating the CA Requirements.

Modification of the Facility.

Various joint and cooperative activities with different agencies.

2.6 Human Resource:

2.6. 1 A Na vigation facility mainte na nce pers onnel should be specialists in the field. An important element

in a preventive maintenance programme is trained experienced personnel. The authority responsible

for the maintenance should have a thorough knowledge of the equipment, should have experience

with extra-ordinary skill and should be able to make careful inspections for necessary repairs and

modifications, if required. It is desirable for the other staff to have professional training. For

maintenance purpose, well-qualified executives can be trained on-the-job if suitable supervision and

instructions are provided. Considerable exposure to the equipment and its operation is desirable.

These individuals should be present or on-call during the operating hours of the station to correct any

deficiencies that may develop.



11

2.6.2 This station is supposed to have a watch round the clock, but due to hardship, a alternate day visit of

the maintenance team is paid to asses the health of the equipments and to execute the desired

maintenance at present.

CHAPTER 4

MAINTENANCE MANAGEMENT

4.1 General:

This chapter provides recommended guidelines for maintenance of navigational aid. Since the function of

such facilities, in context to this station, is to assist in the safe and efficient movement of aircraft while en-

route to destination, it is essential that a high degree of operating reliability be maintained. To achieve, it is

necessary to establish and maintain an effective system of maintenance programme. This section provides

suggestions for establishing this type of programme but, due to the varying complexities prevailing at the

station and facilities provided, such a programme must be tailored to suit each particular need of the time

subject to the condition that the basic sprit should not be compromised.

4.2 Maintenance Philosophy:

The purpose of a maintenance management system is to ensure the maximum availability of any given system

at a minimum cost in man-hours of funds. "Availab ility" and "costs" are relative terms; they must be

interpreted for each fac ility. Maintenance of the navigational aid is a mission essential for all air operations.

Maintenance operations must be scheduled and coordinated with all concerned. The maintenance operations

include maintenance planning, preventive maintenance inspection, visual inspection, repair, ground-calibration

and scheduled maintenance procedures.

The maintenance procedures in this manual are considered minimum guidelines. The fo llowing points are

essential to any controlled maintenance program.

a) Documenting the service checks of the maintenance program.

b) Recording the performance of scheduled or unscheduled maintenance action.

4.3 Maintenance Schedules:

Documenting the maintenance schedule by spelling out each item of routine maintenance is beneficial in

several ways:

a) It allows planned allocation of man-hours to the maintenance function.

b) It helps to establish spare part stock at the appropriate level (SMUs).

c) It identifies the necessary maintenance routines to new staff, decreasing training time needed for

system familiarisation.

d) It identifies to management the scope of the maintenance task in terms of man-hours and materials

requirements.

4.3.1 Preventive Maintenance Inspection Practices (Daily):

Reliable functioning of navigational aids is necessary for air-movement. Though ground support navigational

aid equipment is designed to be dependable and may continue to operate for long periods of time even if the

Two Basic Rules

A potential hazard exists whenever work is performed on or around energized radio/electrical

equipment.

The following basic rules should be followed by a ll personnel:

a) Work should never be performed on energized electrical conductors or equipment, except

for measuring voltage or current. b) Always assume that power is on unt il the true condition is determined.



17

maintenance is neglected, yet it is essential that a preventive maintenance programme be established to ensure

reliable service and proper equipment operation.

An important factor of preventive maintenance programme is an effective Preventive Maintenance Inspection

(Daily) schedule. This daily schedule is the foundation for the successful maintenance of the equipment. If

the daily schedule is performed properly, it will ensure top system performance and will minimize

unscheduled interruptions and breakdowns. A review of the inspection records, checks, tests and repairs

provides a constant awareness of the equipment condition and gives maintenance personnel advanced warning

of impending trouble.

This includes the following checks on daily basis:

i) Building Condition—cracks, leakage etc.

ii) Antennae System and Associated Structure—corrosion, welding, foundation etc.

iii) Room Temperature/Air-conditioning.

iv) Cleaning of equipment/Equpt. Room/condition of PVC flooring.

v) Wiring Condition—abrasions, breaks, and loose connections etc.

vi) Connectors/Electrical Jumpers—looseness, moisture, rusting etc.

vii) Mechanical Systems—lubrication etc.

viii) Rodent/Lizard/Insect Prevention.

ix) Visit to other establishments (Generator Room etc. for similar observations).

x) Lightening Arrester.

xi) Earthing System.

xii) Obstruction Light.

4.3.2 Periodical Maintenance:

Scheduled inspections and tests are those accomplished on specific types of equipment on a periodic basis.

The schedule may be based either on calendar or on hour ly use increments. These schedules are based on

recommendations from the regulatory authority or from the manufacturers and users of the equipment. These

schedules are considered to be the typical requirements to keep the equipment in good condition. In our case

it is a multi-phased programme, viz, daily, weekly, monthly, quarterly, half yearly & annualy. This is

subjected to:

a) Monitoring of operational parameters

b) Perfect functioning of monitoring device (within standard tolerance) and warning/alarm etc.

c) Equipme nt’s be ha vior under the alarm condition (cha nge over, shut down, restart generations etc.)

d) Alignment/Calibration/Tuning of equipment and accessories according to procedure.

4.4 Performance Checks:

4.4.1 The efficiency of any facility depends upon checks and counter checks. The Performance Check is

also a counter check type of maintenance in which the parameter measured has to be tallied /compared with

station’s previous records in a routine or required manner. It includes the following check:

i) Various Voltage/Current levels (available at TPs & jacks)

ii) Wave Shapes

iii) Monitoring Levels

iv) Station Assigned Frequency

v) Power Levels of various signal/Output Power

vi) Level of internal signal generators.

vii) Modulation Percentage

viii) VSWRs

ix) Lightening Arrester

x) Earthing System

4.4.2 All these checks should also be carried out for associated units/test equipments to assure the safe

operation of facility.

4.6 Troubleshooting:

Before attending the any equipment/unit, it may be ensured that power supply to the equipment/unit is of

specified rating. In case of AC supply, the voltage and frequency is of rated value whereas in case of DC

supply voltage and ripple filtering is very important.

The common approach of troubleshooting is:

i. Smell out any burnt/overheating component.

ii. Check-up for male/female connector along with its pins and ensure its proper insertion.

iii. Similar exercise may be carried out for all edge connectors and ribbon connectors.

iv. Check the earthing of the equipment. Improper/floating/dry earth sometimes plays havoc despite

of perfect status of the equipment.

To avoid any further damage, It is advisable to isolate the onwards stages or to reduce the power handling

level if and only if the situation permits.

These were the only general methodology for fault finding. It is recommended that a procedural approach

referring to manufacturer’s manual should be adopted for the purpose. A record to this effect should also be

made in the Fault Log Book.

4.7 Tools & Test Equipments:

An important element in a maintenance programme is the tools and test equipment required to perform the

task. This includes the proper tools, test equipment, adequate working space, adequate storage space, spare

modules and applicable technical manuals. Carrying out the maintenance with the perfect and calibrated test

equipments curbs the equipment failure, false signals, and deterioration of the system.

4.8 Maintenance Records:

Maintenance records are an important part of an effective maintenance management system. They provide a

service history of each piece of equipment’s sub-units, ensure regular maintenance without duplication of

effort, and give a data base for statistical analysis of system performances. Without records, knowledge

gained from regular inspections will not be retained, and preventive maintenance will be d if f icu lt. An

effective records system should a llow for the recording and retrieval of information with a minimum of

effort. The records system should compile data that will document the effectiveness of the maintenance

program. By checking the records, a proficient executive will be able to determine whether a particular

maintenance task is being done too frequently or not often enough.

Since corrective and preventive maintenance procedures for the equipment are adequately addressed in CHQ

CNS Manual, this manual contains the compact, recompiled and comprehensive user friendly parameter

recording formats for the maintenance schedules as well as the status reports to be sent to respective RHQ as

per the instructions. These are given in Annexure pages as detailed below:

4.10 Preservation of Records:

There is no set period of time that maintenance records should be kept, but, in keeping with in the goals

mentioned above, the respective period of preservation of record for each type of maintenance with respect to

facilities at this station is well defined in CNS Manual, Vol. I and is appended below:

i) Daily One year

ii) Weekly One year

iii) Monthly One year

iv) Quarterly Five year

v) Six Monthly/Annual Five year

vi) Ground Calibration Repots One year

vii) Flight Calibration Reports Last 5 Reports along with commissioning report

viii) Performance Indicator Report One year

viii) Fault Log Book Till discarding of the equipment

4.11 Reference Library:

A reference library should be established to maintain a master copy of a ll equipment’s technical manuals,

advisory CNS circulars, as-built drawings, master copy of this manual and other useful technical data such as

local electrical codes/wiring diagrams, test equipment manuals etc. An office of primary responsibility should

be established to maintain the records.

IMPORTANT CAUTION

After every maintenance, it should be ensured that all the parameters of both (main and

Standby) equipments must be normal and well within the tolerance limits as specified by

ICAO/CA Requirements otherwise carry out a fresh procedural exercise and recordA ground

check/flight check of VOR, as the case may be, is also advisable to ensure air safety



22

CHAPTER 5

CRISIS PLANING AND COORDINATION

5.1 General

The air-space with few operations may suffer with a litt le inconvenience to pilot as well as to ground

controller in managing the show without Navigational Aid but the management of a crowded air-space without

the provision of such aid is quite risky for the both. That too if failure occurs at a critical time, it may lead

lives and property be jeopardised. The concept of Hot Stand-by has solved the problem up to certain extent,

still unpredictable failure of the facility sometimes inevitable due to natural reasons. Hence navigational aid

restoration should receive high priority in the interest of air-safety.

5.2 Availability of serviceable card/module/unit:

This section contains guidelines on how to manage serviceable modules to be replaced, co-ordination with

appropriate levels for quick restoration of station facility.

5.2.1 Special Maintenance Units (SMUs):

Under the modernisation plan, the AAI has adopted a cetralised maintenance workshop

concept (CMC/SMUs) at different airports for different facilities. The Special Maintenance Unit (SMU), New

Delhi is identified as the cetralised maintenance unit for the facilities commissioned at this station.

In the event of unexpected failure of facility and in order to minimising the facilities out of operation time,

following guidelines have to be adopted:

a) Isolate, pack and dispatch the faulty module/card along with telephonic coordination to SMU, New

Delhi. Intimate via e-mail to CMC with a fault briefing report as per Performa CMC-01. (Ref.

Caution ‘f’ in packing ESD sensitive device, Annexure page A-2)

b) SMU, in turn, acknowledges station by raising a Site Anomaly Report (SAR) as per Performa CMC-

02.

c) After servicing and hot check or replacement, the card is again dispatched back to station as per

Performa CMC-03.

d) Upon receipt of the module/card at the station,

i) if the performance is satisfactory—Normalise the station and intimate all concerned as well as

SMU to close SAR as per Performa CMC-04.

ii) if the performance is faulty—Again dispatch the faulty module/card along with telephonic

coordination to SMU, New Delhi according to defined procedure bearing the same SAR

number.

5.3 Effect of the Failure:

The effect of the failure of a particular spare part depends on how important the part is to the equipment it is

installed in, and/or how vita l the equipment is to operation. For example, the failure of an indicator lamp in

a unit would not lead to any system downtime whereas any breakdown in a circuit board/module would

cause the failure of the entire facility. The recurrence failure of a particular card/module/unit should be given

due consideration to sort out the problem permanently.



23

5.4 Facility Malfunction:

In the event of failure of a facility irrespective short-termed or prolonged, It is mandatory for the service

provider to coordinate with appropriate authority who can inform all such time-critical aeronautical

information to every concerned which could affect a pilot's decision to make a flight. Even after restoration of

the facility similar liasoning is mandatory.

5.4.1 NOTAM (Notice to Airmen):

It is a notice distributed by means of telecommunication containing information concerning the establishment,

condition or change in the status any aeronautical facility, service, procedure or hazard, the timely knowledge

of which is essential to all concerned parties involved in flight operations. The person in charge of the watch

shall report any known or reported malfunctions of a NAVAID to technical operations or appropriate

personnel and coordinate issuance of a NOTAM.

In the case of this station and under such circumstances, all time based coordination has to be carried out with

WSO (Tech.), Palam, New Delhi. (Phone: 011-25653492) with the following details:

Specify an acceptable recovery time for the shutdown facility.

The procedure to be repeated if the acceptable recovery time of a service is exceeded or

Specify time about the restoration of the shutdown facility, if already restored.



24

CHAPTER 6

MONITORING AND SAFETY

6.1 General:

To establish the technical efficiency, maintain safety and adequate levels of reliable service of these facilities,

a continuous monitoring is being carried out. The systems do have automatic monitoring that shut down the

equipment if it puts out an unsafe signal. Unmonitored, as used in this order, means that the personnel

responsible for monitoring the facility have lost aural and visual monitoring capabilities and cannot observe

the status of the facility or not physically present at the site. It does not refer to the automatic monitoring

feature. Monitoring is accomplished in following ways:

6.1.1 Executive Monitoring:

It is an electronic means in which the system checks its critical parameters itself and in the event of an out of

tolerance condition, either changes to an auxiliary back-up equipment or shuts the system down if there is no

redundancy or if the redundant circuit is also failed. This monitoring is continuous.

6.1.2 Status Monitoring:

This is an automatic notification, either to the maintenance centre or to an operational position, that the system

has taken an executive action and the navigation system is changed over or off-the-air. Many NAVAIDs are

not continuously status–monitored.

6.1.3 Ground Calibration:

The monitoring of the composite signal at pre-defined bearings on ground leads to an estimated consequence

of correct formation of signal pattern in the air. This ground Calibration is usually carried out once in a month

or as per the requirement.

6.1.4 Air Calibration:

NAVAIDs are flight inspected by specially equipped aircraft on a regular basis to ensure that standards are

met and certifies the facility is air-worthy. In case of CVOR/DME, It may be noted that it has to be carried out

at an interval of every 240 ± 30 days.

6.1.5 Pilot Monitoring:

When a pilot tune and identify NAVAIDs prior to use and afterwards gets the satisfied performance of the

facility as per the standards, this is called Pilot Monitoring.

6.2 Safety:

It is the responsibility of every AAI employee involved with the CNS activities to understand and help achieve

the following safety goals:

• Provide a safe and healthful working environment for all other colleague employees.

• Incorporate safety aspects into maintenance operations planning.

• Reduce operating costs and increase mission capability by protecting human and material assets.

• Eliminate hazardous conditions.

Similarly, the aviation safety program is composed of three elements. They are standardization, compliance,

and hazards identification.



25

• Standardization is an ongoing responsibility of all personnel associated with aviation activities.

• Compliance with safety policies, procedures, and practices as spelled out in this manual and associated

document is the responsibility of every maintenance team.

• The Hazard Identification System is both an informal and a formal reporting system. Aviation

personnel are expected and encouraged to inform their subordinates of a hazard.

The end result of these combined efforts of all above is a navigation system that is safe, reliable and air-

worthy and meets the established standards.

TIPS FOR MAINTENANCE

ELECTROSTATIC DISCHARGE & GENERAL WARNINGS FOR ALL EQUIPMENTS

CAUTION: THIS EQUIPMENT CONTAINS ELECTROSTATIC DISCHARGE (ESD) SENSITIVE

DEVICES. TO PREVENT ESD SENSITIVE EQUIPMENT FROM POSSIBLE DAMAGE, OBSERVE THE

FOLLOWING PRECAUTIONS WHEN HANDLING ANY ESD SENSITIVE CARD/UNIT/MODULE:

a. Maintenance or service personnel must be grounded though a conductive wrist strap, or a similar

grounding device, using a 1 MΩ series resistor for equipment protection against static discharge, and

personal protection against electrical shock.

b. All tools must be grounded (including soldering tools) that may come into contact with the equipment.

Hand contact will provide sufficient grounding for tools that are not otherwise grounded, provided the

operator is grounded through an acceptable grounding device such as a wrist strap.

c. Maintenance or service of the faulty card/unit/module must be done at a grounded, ESD workstation i.e.

SMU, New Delhi.

d. Before maintenance or service of the equipment, disconnect all power sources, signal sources, and loads

connected to the unit.

e. If maintenance or service must be performed with power applied, take precautions against accidental

disconnection of equipment components. Specifically, do not remove integrated circuits or printed circuit

boards from equipment while the equipment has power applied.

f. All faulty ESD sensitive faulty card/unit/module are to be transported to SMU in electrically conductive

foam bags. The faulty card/unit/module should preferably be stored using the original container/package

when not being used or tested. If the original storage material is not available, use similar or equivalent

protective storage material.

g. Whenever a faulty ESD sensitive card/unit/module is removed, the same must be placed on a conductive

surface, or in an electrically conductive container.

h. When in storage or not being repaired, all printed circuits boards must be kept in electrically conductive

bags, or other electrically conductive containers.

i. Do not unnecessarily pick up, hold, or directly carry ESD sensitive devices. Failure to comply with these

precautions may cause permanent damage to ESD sensitive devices. This damage can cause devices to fail

immediately, or at a later time without apparent cause.



A-3

PERSONNEL SAFETY

General:

The information is annexed that will help facility personnel in establishing an effective safety program.

Safety is the responsibility of each individual, regardless of position. Safety must be practiced daily in every

maintenance activity that is performed. The safety program established at each facility should include

preventive safety precautions, and first-aid procedures for use in the event of an injury.

First Aid:

First aid is essential before professional help arrives. It is never a substitute for medical help. The

professionals should take the lifesaving measures necessary in emergencies, but avoid doing harm. Many

first-aid measures are quite simple. Haste without knowing what one is doing can be worse than doing

nothing at all. At other times, immediate action is essential to save a life or prevent serious complications;

this action can only be taken by someone who is on the scene when minutes are vital. Learn about first aid

before emergencies happen. Be prepared to give help safely and beneficially when necessary.

Causes of Accidents:

Some common causes of accidents are:

a) Working on equipment without adequate coordination.

b) Working on equipment without sufficient experience on that equipment.

c) Failure to following instructions in equipment manuals.

d) Failure to follow safety precautions.

e) Using unsafe equipment.

f) Failure to use safety devices.

g) Working at unsafe speeds.

h) Poor housekeeping of work areas.

Safety Procedures and Guidelines:

Most navigational aids equipped with obstruction light are exposed to weather and moisture and may develop

electrical shock hazards through damage from lightning or insulation deterioration from exposure.

Maintenance procedures should begin only after a visual inspection has been made for possible hazards. Due

to the danger of lightning, navigational aids should not be serviced during periods of local thunderstorm

activity. Develop and implement a set of action plans to follow in the event of an accident occurring. A

known set of predetermined responses should be in place to ensure that positive responsive actions take place

within moments of accident notification. Precious seconds are saved getting medical assistance to those in

need when action plans are in place. Action plans should be rehearsed and reviewed regularly.

Safety Practices:

The following safety practices should be followed by all personnel performing maintenance of Nav-aids:

a) Workers should be trained and familiar with electrical safety.

b) Safety rules should be strictly observed.

c) Commercial test equipment should be of standard quality.

d) Prior to beginning any maintenance work on equipment, coordinate the work schedule with the

appropriate authority at the station/regional headquarter level. Make sure circuits will not be

energised during maintenance, and obtain authorisation for local control if equipment is normally

operated from a remote control point.



A-4

e) Whenever maintenance work is to be accomplished, at least two persons should be assigned, with

one having a thorough knowledge of the layout of the equipment. The duties of the other person

include:

(1) Keeping other personnel not involved in the work clear of the equipment.

(2) Being familiar with power disconnects and immediately disconnecting the power source in case

of emergency.

(3) Being qualified in first-aid and prepared to render emergency, if necessary. The observer should

bear in mind that prevention of an electrical accident is of primary importance even though first-

aid treatment is available.

(4) Observing the work being done to detect and warn against unsafe practices.

Safety Training:

A safety training course may be established and presented to all employees. Follow-up training should be

presented on a periodic basis to ensure that employees are safety motivated. Coordinate with the local

medical authorities to arrange for proper training.

Personal Safety Precautions:

The following commonsense safety precautions should be standard procedure for every professional:

a) Know the location of main power disconnect devices.

b) Know how to summon medical aid.

c) Remove necessary fuses to de-energize the circuit using properly insulated fuse pullers. Consult

circuit diagrams to identify all fuses involved. Remember that removal of a fuse does not remove the

voltage from the "hot" fuse clip. Discharge all capacitors.

d) Do not depend on interlocks to remove power or on indicating lights to signal that power is off.

Verify that voltage is off by using a voltmeter on the component after opening the power switch.

e) Insulate feet by standing on a dry rubber mat. However, remember that, contact with the grounded

equipment cabinet could nullify this protection.

f) Stay clear of terminals, leads, or components which carry voltages of any magnitude. Also, avoid

contact with components which are grounded, including the frame.

g) De-energize the equipment when it is necessary to reach into the equipment in locations where rapid

and direct withdrawal of the hand is not possible. In any case, only one hand should be exposed,

with the other hand kept away from contact with voltages or ground.

h) Be certain that there is no power applied to a circuit when making a continuity or resistance check (the

meter will be damaged.)

i) Ground the test equipment to the equipment under test unless otherwise specified in instruction

manuals.

j) Place a warning sign, such as "DANGER - DO NOT USE OR OPERATE", at the main switch or

circuit breaker, and provide a lockout for the circuit on which you will be working.

k) Do not wear jewelry, wristwatches, metallic bangle or rings while working with electrical

equipment.

l) Keep clothing, hands, and feet dry if at all possible.

m) Use the correct tool (screwdriver, alignment tool etc.) for doing the job.

n) Never use toxic or flammable solvents for cleaning purposes.

o) Where air pressure is required for cleaning, use a low-pressure air source. Eye protection (goggles or

face mask) is necessary when using compressed air for cleaning.

p) Do not take anything for granted when working with inexperienced help.

Some more safety items to be followed are:

a) A vehicle.

b) Accident and fire procedures.

c) Emergency telephone numbers, such as doctor, hospital, rescue squad, and fire department.

d) First-aid kit.



A-5

e) Rubber gloves.

f) Insulated fuse puller.

g) Nonmetallic flashlight.

h) Grounding stick.

i) Safety posters and bulletins.

j) Fire extinguisher.

Electric Shock:

An electric shock is the passing of an electric current through a person. The amount of damage depends on the

level of voltage and the amount of current to which the person is subjected.

a) Voltages between 200 and 1000 volts at commercial power line frequencies are particularly harmful

since under these conditions heart muscle spasm and paralysis of the respiratory center occur in

combination. However, the possibility of lower voltages to be proved fatal can not be eliminated. The

body response to current is as follows:

05-to-15 mA stimulates the muscles;

15-to-19 mA can paralyse the muscles and nerves through which it flows;

25 mA and above may produce permanent damage to nerve tissues and blood vessels; and,

70 mA and above may be fatal.

b) The injurious effects suffered during electric shock depend upon the path of the current through the

body. The current path will take the most direct route through the body from the two points of

contact. For this reason, any current path which involves the heart or the brain is particularly

dangerous. Therefore, keeping one hand clear of the equipment will eliminate the possibility of a

current path from arm-to-arm.

Soldering Safety:

a) Soldering can be a safe process if the hazards are recognized and normal safety precautions are

observed. The hazards include heat, fire, shock, fumes, and chemicals.

(1) Heat. Since soldering is a process which requires heat, the danger of burns is always

present. Burns can be received from the primary source of heat (the soldering iron

or soldering gun), from explosions caused by open flames, and from handling

soldered metals before they have cooled sufficiently.

(2) Fire. Closely associated with the danger of heat is the danger of fire. Fires can result

from the careless handling of heated devices or their use near of flammable

fumes or liquids.

(3) Fumes. Volatile fumes are an invisible hazard that may damage both personnel and

property.During the soldering operation, the danger may be decreased by providing

adequate ventilation. Combustible gases, such as acetylene or fumes from

gasoline or alcohol, present an explosion hazard. Fumes are dangerous to breathe;

fumes fromheated fluxes and degreasing liquids can cause lung and skin irritations.

(4) Shock. Since electrical soldering equipment is commonly used, the possibility of an electrical

shock is present. Electrical defects in soldering equipment and associated supply

circuits may expose the technician to dangerous voltages. This hazard can be

minimized by the use of equipment in good condition.

(5) Chemicals. Chemicals which may present a health hazard are used extensively in soldering fluxes

and degreasing solutions. Non-corrosive fluxes present little problem, but the alkalis

and acids used in corrosive fluxes may cause skin irritations and burns. Danger to

the eyes also exists since many of the chemicals are in liquid solutions, and

splashing or spattering may occur. The hazard presented by chemicals is slight if

proper safety precautions are observed.

b) Many precautions are common to all types of soldering and should be observed to prevent injury or

damage to property.

(1) Do not solder electrical equipment unless it is disconnected from the power supply. Death can

result from contact with the high-voltage source being worked on.



A-6

(2) Ground all equipment to lessen the danger of electrical shock.

(3) Ground electrical soldering irons and guns when feasible. Grounding will minimize the danger of

electrical shock resulting from defective equipment. It will also reduce the danger of the

soldering equipment producing a spark in explosive areas. Grounding will also protect

semiconductor devices by neutralizing any differences in potential between the soldering

equipment and the semiconductors in transistor equipment.

(4) Do not flip excess solder from the tip of a hot soldering iron. Bits of hot solder can cause

serious skin and eye burns; they may also ignite combustible materials.

(5) Do not handle hot metals; allow the pieces to cool before handling.

(6) Select the proper working area for soldering. Choose a well-ventilated location away from all fire

hazards.

(7) Mechanically secure large work pieces while they are being soldered. Severe injuries or burns may

be received because of a falling work piece.

(8) Wear the proper clothing and protective devices while soldering.

(9) Maintain a clean working area to prevent fires. Remove combustible materials from the floor and

from the surrounding area.

(10) Keep fire-fighting devices and first-aid supplies near the soldering area. All equipment should be

checked at regular intervals.

Lightning/Thunderstorm:

The following rules for personnel safety should be observed during Lightning/Thunderstorm

(1) Remain indoors unless absolutely unavoidable. Stay within a dry area of the building, preferably away

from all metal objects.

(2) If there is a choice of shelter, select a suitable shelter such as large metal or metal-frame buildings,

buildings which are protected against lightning, or vehicles.
