4 Safety requirements and/or -measures

4.1 General

Spray booths shall comply with the safety requirements and/or protective measures of Clause 4. In

addition, spray booths shall be designed according to the principles of EN ISO 12100:2010 for relevant

but not significant hazards (for instance sharp edges), which are not dealt with by this standard.

The safety requirements defined in this standard override the requirements defined for minimizing

energy usage and environmental impact (see Annex F).

4.2 Mechanical

4.2.1 Moving or rotating elements

Hazards by shearing, crushing or drawing-in by movements of machine parts and equipment shall be

prevented by design. Access to dangerous moving parts shall be prevented. This can be achieved by

fitting fixed guards

and/or

fitting one of the following devices interlocked with the hazardous movement

movable guards, see EN ISO 14120: ;

active opto-electronic protective devices, see EN 61496-1:2013 and EN 61496-2:2013;

Ignitability of water-based paint

The investigation of more than 200 water-based paint for the combustion behaviour of the sprayed paint

has led to the classification of water-based paint given in Table E.1. See PTB-

-Technische

Table E.1 — Ignitability of water-based paint

Class Composition

Non-ignitable [% by weight H2O] > 1,7 x [% by weight LM] + 0,96 x [% by weight ORG]

Spray clouds of non-ignitable paint cannot be ignited. If also the rinsing and thinner

liquids correspond to this category, no explosion protection is necessary.

Hard to ignite [% by weight H2O] > x [% by weight ORG]

Spray clouds of hard to ignite paint cannot be ignited by sparks having an

energy < 4 Joule. Usually, explosion protection in the spraying area is not necessary,

provided no ignition sources with energies of more than 2 Joule are present.

Ignitable [% by weight H2O] < x [% by weight ORG]

Spray clouds of ignitable paint can be ignited by sparks having an energy < 4 Joule.

Annex G(informative)

Examples for safety related controls

G.1 General

This annex provides information on the design of safety functions for spray booths as defined in 4.7.3 and

4.9 of this standard.

The examples given only illustrate the safety related block diagram in respect to the architecture of the

category (see EN ISO -1). All other aspects requested by the respective PL like values for the mean

time to hazardous failure, the diagnostic coverage, measures regarding common caused failures or safety

related software are not considered. See Table 2 for abbreviations used in this standard.

G.2 Interlocking of forced ventilation system with interface to spray application

A safety function with an outstanding interest is the interlocking of the forced ventilation system with the

interface of the spray application. In this example for automatic spray booth PL c is required for safety

requirements against explosion (see 4.9).

Usually the exhaust flow rate is detected by e.g. a differential pressure switch cutting of the excitation

current of an electromagnetic pneumatic valve when a certain value (lower limit) is reached. This valve

can be utilized to deactivate the material and/or pressured air supply in a spraying process.

The typical solution for realizing a PL c is the category 1, using so called well-tried elements. If no well-

tried elements are available, i.e. for most kind of electronic devices, a category 3 system (redundant)

could be an alternative solution. The conditions for well-tried pneumatic valves are not determined

exactly in Annex B of EN ISO -2:2012, but it describes a method for estimation.

For determining a sufficient air flow, the state-of-the-art solution is a Pitot tube with a differential

pressure switch. The measurement task is comparatively challenging (due to turbulences etc.) and the

reliability of the sensor may be critical if some dust is present even behind the filtering system. Therefore,

in general a comparatively simple system for determining the air flow is not considered to be a well tried

element according to EN ISO -1: .

One solution for this problem is the combination of a Pitot tube and a differential pressure switch with a

purging unit for cleaning the Pitot tube. Under certain conditions this is considered to be a well proven

technology and fulfils the requirements for category 1 („well-tried element“). Since during the purging

process (controlled via a timer) the pressure switch has to be bypassed, the purging unit is safety

relevant. The electronic device controlling the purging interval may be a certified system, typically PL d

or even PL e. Figure G.1 shows the respective safety related block diagram.

FprEN 16985:2017 (E)

83

Figure G.1 — Interlocking of forced ventilation system with interface to spray application

utilizing mainly safety related elements in category 1 (except of electronic device)

If for some reasons no well-tried sensors are available, choosing a category 3 architecture could be a

reasonable solution, see example in Figure G.2. The two redundant contactors (category 3) are connected

electrically in serial with the pneumatic valve (category 1). The dashed arrows connecting the differential

pressure switches with the PLC indicate measures to achieve a diagnostic coverage according to the

requirements for category 3. See Table 2 for abbreviations used in this standard.

FprEN 16985:2017 (E)

84

Annex H(informative)

Determination of the spray booth clearance time using smoke

H.1 General

The clearance time of a fully enclosed spray booth can be estimated with smoke to visualize the air

movement.

The smoke is unlikely to clear uniformly from the booth as it depends on the shape of the booth, the

ventilation rate and the size and position of the ventilation openings. For example smoke is most likely

to linger and form eddies close to all the walls of a vertically ventilated spray booth.

The clearance time shall be determined on a fully operational spray booth with fitted filters. To carry out

this procedure a large smoke machine is necessary.

H.2 Procedure

The following steps allow the clearance time of a spray booth to be determined:

a) The spray booth shall be empty when measuring the clearance time.

b) The spray booth shall be set up for normal spraying operations.

c) Fill the booth with smoke, making sure to distribute smoke evenly throughout the space. Ensure that

the extraction system is turned off as it may be difficult to sufficiently fill the booth with smoke with

the ventilation running. The booth should be regarded as full when the facing wall is no longer visible

when viewed across the short axis of the booth

d) Switch on the forced ventilation and start a timer.

NOTE During the smoke test the opportunity should be taken to carry out a visual inspection of the exterior of

the spray booth and any associated ducting to check for any leaking air.

e) The spray booth shall be regarded as clear when smoke is no longer visible in any part of the spray

booth. A lamp viewed from a narrow angle towards the beam of light may be useful in judging this,

though ensuring that the spray booth is truly full at the start of the measurement is more important

than precise judgement of when the smoke has cleared. The difference between clear by eye and clear

using a lamp is typically 30 s longer. The time at which the spray booth is judged to be clear of smoke

should be rounded up to the next quarter minute. This is the clearance time of the spray booth.

The fluid used in most smoke machines is glycerine or glycol based and as such is of low toxicity but may

cause a slight irritation of the throat because of the high concentration. It is no good practice to expose

people to high smoke concentrations, therefore appropriate breathing protection should be worn during

the clearance time measurement; a disposable dust mask with a combination A/P3 filter will suffice.
