1. GENERAL AND PERSONAL HEALTH AND SAFETY REQUIREMENTS AND PROCEDURES
PERSONAL SAFETY PROCEDURES: Has to do with the way in which a person is attired for the workshop or worksite for practical activity.
Always wear your personal protective equipment (ppe)
Do not wear defective ppe
GENERAL AND PERSONAL HEALTH AND SAFETY REQUIREMENTS AND PROCEDURES
GENERAL SAFETY PROCEDURES: has to do with the general working environment.
Clean up all spills immediately Keep workshop clean Ensure all machine guards are in place
before use.
1.2 APPROPRIATE HEALTH AND SAFETY MATERIALS, ACCESSORIES
Accessories: Any thing that can be added to something else in order to make it more useful, versatile, or attractive.
Safety materials: items used to prevent injury or damage to someone or something
1.2 APPROPRIATE HEALTH AND SAFETY MATERIALS, ACCESSORIES
Equipment: supplies; items; instruments, tools or other things needed for completing a specific task

1.2 APPROPRIATE HEALTH AND SAFETY MATERIALS, ACCESSORIES
Gear: Personal Protective Equipment (PPE)or clothing - Specialized clothing or equipment worn by employees for protection against health and safety hazards. Personal protective equipment is designed to protect many parts of the body, i.e., eyes, head, face, hands, feet, and ears.

FIRES
Fires can be classified into Five groups – A, B, C, D and K.
Class A fires are common combustible materials
such as wood, cloth, paper and packing materials.
Class B fires are of flammable liquids such as petrol,
kerosene, oil, grease, fat, wax, paint, thinners
lacquers and solvents.

such as magnesium, potassium, and
sodium.
Class K fires are caused by household
chemicals such as aerosol spray, candles,
nail polish remover, acetone, etc.
FIRE EXTINGUISHER AND THEIR USE(S)
EXTINGUISHER TYPE HOW IT WORK EFFECTIVE AGAINST

FIRE FIGHTING As with all workplace hazards, fire should be dealt with immediately
and quickly. Various types of portable fire extinguishers, fire
blankets, hoses and water can be used to extinguish fires.
If you observe a fire, here are some useful tips of SAFETY:
• Sound alarm
• Advise fire brigade
• Fight fire
• Evacuate
• Tell everyone to get clear
• You get clear
Never use water on a Class B fire as it may Spread the burning liquid.
PROCEDURES TO USE AN EXTINGUISHER
1. Remove extinguisher from rack/box
2. Hold upright, pull ring pin3. Start back 10 feet, hold flexible
hose with one hand aiming the nozzle at the base of flame
4. Squeeze operating handle or lever; sweep from side to side
1.3 DEFINITION OF FIRST AID
This is the emergency
care/treatment given to a victim
of sudden injury or illness before
more skilful or professional
medical care is given/accessed
IMPORTANCE OF FIRST AID
First aid may save a life or improve certain vital signs including pulse, temperature, a patient (unobstructed) airway, and breathing.
In minor emergencies, first aid may prevent a victim’s condition from worsening and provide relief from pain.
ACCIDENT
An accident is an unexpected, unplanned
and undesirable event, which causes – or
nearly causes – human injury or damage to
property.
Examples: falling from a ladder, objects falling
from overhead, etc.
Accidents mean suffering and loss for everyone!
Accidents seldom just happen – they are usually
caused!
CAUSES OF ACCIDENTS
Carelessness - Fooling around, running about.
Paying no regard for others working near you.
Not paying attention to safety rules.
Ignorance – of the dangers of a machine or
tool, and of safety precautions.
Unsuitable clothing – Large, loose clothing,
unbuttoned shirt, wearing neckties.
Untidiness – Overcrowded passageways,
objects on the floor, grease or oil on the floor.
Hand Tools – Using dull blunt or broken tools.
Using incorrect tools.
Exposed Eyes – Not wearing proper eye
protection during practical work.
Machine Tools – No knowledge of how to
operate machines. No permission to use
machines. Machine tools and parts not
secured properly.
Lifting Objects – Lifting anything that is too
heavy for you to manage.
INJURY
A instance of physical harm or damage suffered
Examples: fractures, burns, bruises, strains, Sprains, etc
EMERGENCY
A sudden and unexpected event
requiring immediate attention
Example: weak or slow breathing, heart
stops, Injuries of the skin(2nd & 3rd degree
burns and fractures)
FIRST AID PROCEDURESAssessing the situation(what to treat first)
1. Don’t panic: psychological support is essential
2. Remember the ABC’s of life support
Airway open: open and maintain victim’s airway
Breathing restored: if not breathing, begin rescue
breathing technique
Circulation maintained: if no pulse is present, begin
CPR (by blowing 1 rescue breath into victims mouth
after each 5 external cardiac compressions)
3. Check for bleeding: a) apply direct pressure
b) Elevate injured limb only if it doesn’t cause further
pain or injury c)Apply pressure on supplying artery.
Only use a tourniquet for severe life threatening
hemorrhage as a last resort when all other
measures fail.
4. Look for signs of shock and broken bones
(fractures)
5. Look for an emergency medical identification tag
on the victim’s wrist, ankle or neck.
6. Get professional medical help quickly.
Know emergency numbers. Telephone
appropriate authorities and describe the
problem. Be sure to give your name,
location and the number of persons
involved.
7. Loosen any clothing that may restrict
victim’s breathing or interfere with
circulation.
8. Never give an unconscious person
anything by mouth.
9. Do not move injured persons unless
situation is life threatening. Keep victim
still, quiet and warm (except heat
exhaustion and sun stroke). Victim with
broken bones should not be moved until a
splint has been properly applied
BODY PRESSURE POINTS
IDENTIFY SAFETY HAZARDS
Health and safety hazards exist on construction
worksites; therefore, it is your responsibility to
first, identify the hazards and then take the
necessary actions to minimize the risks.
All workplaces have hazards that could cause
injury or illness. These situations not only cause
personal suffering and loss of income, but also
loss of productivity and property damage.
HAZARDS
Anything that can expose a person to
danger or injury.
Hazardous situations, if detected early and
corrected speedily, can significantly reduce
the chances of accidents occurring.
TYPES OF WORKPLACE HAZARDSTripping: cluttered work area, unsecured extension
cords, obstacles in walkway, protruding objects,
Limited storage space – results in materials not being
stacked correctly to facilitate easy retrieval
Health: Fumes and gases - exposure to toxic substances and chemicals; Dust - exposure during sanding and clean up activities; Garbage in workshop, improper lifting technique
Electrical-improper grounding, use of extension
cords with worn insulation, exposed wires or misuse of
electrical equipment, trailing electric leads
Chemical: Solids, Liquids, Gases
Mechanical: faulty equipment and
machinery, Malfunctioning machinery
Physical: Noise, Heat, Sun, Vibration,
Manual handling of tools and equipment,
Poor lighting – tools cannot be applied
effectively in areas that are not well lit
Fire: use of heat gun not in accordance
with directions, improper storage of
flammable Substances, oily rags
CAN YOU IDENTIFY EACH HAZARD?
WHAT TO DO
When you have identified safety
hazards in your work environment,
you need to take the necessary steps
to implement procedures to reduce
risk to self and others. These include:
Using correct tools and equipment
and reporting defective equipment
WHAT TO DO
Wearing appropriate Personal
Protective Equipment (PPE)
Handling materials safely
Adhering to workplace, environmental
and safety regulations.
Securing hazardous materials and
substances
Reporting incidents, illnesses or injuries
to your supervisor immediately
Reporting potentially hazardous
situations promptly to your supervisor
Using fire fighting equipment and
carrying out first-aid procedures in the
event of an emergency
1.4 SAFE AND HEALTHY WORKING ENVIRONMENT
A safe and secure working environment
is one which eliminates or minimizes:
1.The chances of fire occurring
2.Accidents such as falls, cuts, burns,
electrical shocks
3.Theft
4.Fraud
SAFE AND HEALTHY WORKING ENVIRONMENT
Falls: to reduce the chance of
someone falling, the following may
be used:
1.Non skid mats on surfaces which
may be slippery
2.Appropriate safety signs such as
“wet floor”, “watch your step”
SAFE AND HEALTHY WORKING ENVIRONMENT
Theft: use burglar alarm, door
chains, security camera,
Fire: use fire extinguisher, fire
alarm, smoke detector, wet blanket,
sprinkler, sand
WASTE DISPOSAL
Rubbish and scraps should be
placed in containers until disposal
can be made. Instead of burning
treated wood, bury or place them in
an ordinary trash collection bin or
dumpster which should be placed on
the site.
