OSHA

Section 5(a)(1) of the OSH Act, often referred to
as the General Duty Clause, requires employers
to "furnish to each of his/her employees
employment and a place of employment which
are free from recognized hazards that are
causing or are likely to cause death or serious
physical harm to his/her employees". Section
5(a)(2) requires employers to "comply with
occupational safety and health standards
promulgated under this Act".
Effect of Lighting………

Proper lighting (bright
& fluorescent) along
with light color
painted walls in the
Spray Paint room so
that workers/students
can see better when
spray painting.
Selection of Respirators
Employer must select and provide an
appropriate respirator based on the respiratory
hazards to which the worker is exposed and the
factors that affect respirator performance and
reliability.
A pressure gauge that indicates airflow outside the booth
will make it easier for instructors to determine when to
replace the booths air filters.
CLEAN FILTERS

Replacing clogged air filters keeps the paint
booth’s ventilation system working efficiently
to remove paint and solvent mists,
protecting the painter and others from
overexposure to potentially hazardous
substances and decreasing the risk of fire
due to flammable vapors.
SPRAYING APPLICATIONS
A spray
application is also
particularly hazardous
because it creates fine
droplets of the fluid, making
the fluid more ignitable than
when it is applied with a
brush.
FOLLOW GOOD HOUSEKEEPING
 Combustible
cardboard
boxes should
not be stored in
the booth and
filters are not
stored properly.
STORED CHEMICALS

Store only the required
amount(s) of flammable liquid
for one classes usage at the
spraying area. Liquids need
to be contained to tight fitting
safety containers and labeled
properly. Any bulk storage
should be stored in a
separate storage facility on
site or outside the school.
The larger the amount stored
and used, the greater the
potential for improper
handling and/or spillage.
ERGONOMICS IN THE BOOTH
CHECK POINTS

Are No smoking signs
conspicuously posted. Ref:
1910.107(g)(7)
 Is the electrical equipment in an
electrostatic hand spraying area
interlocked with the ventilation
system so that it cannot be
turned on unless the ventilation
fans are operating? Ref:
1910.107(I)(8)
 Are automatic sprinkler heads
located so as to provide water
distribution throughout the spray
booth? Ref: 1910.107(f)(1)

Are fire extinguishers installed
near all spraying areas? Ref:
1910.107(f)(4)
 Is all residue, scrapings, and
debris contaminated with residue
immediately removed from the
premises and properly disposed
of? Ref:1910.107(g)(3)
 Are approved metal waste cans
provided whenever rags or
waste are impregnated with
finishing material and are rags
and waste deposit in them
immediately after use?
Ref:1910.107(g)(3)
CHECK POINTS II

Are freshly sprayed articles dried
only in spaces provided with
adequate ventilation? Ref:
1910.107(d)(12)
 Is mechanical ventilation being
operated during all spraying
operations and for a sufficient
time afterward to allow vapors to
be exhausted?
Ref:1910.107(d)(2)
 Does the quantity of flammable
or combustible liquids that are
kept in the vicinity of spraying
operations exceed a supply
needed for one shift? Ref:
1910.107(e)(2)

Is a visible gauge, audible alarm,
or pressure-activated device
installed to ensure that the
required air velocity is
maintained?
Ref:1910.107(b)(5)(i)
 Are only fixed lighting units used
as a source of illumination? Ref:
1910.107(b)(10)
 Are spray booths installed so
that there is a clear space of not
less than 3 feet on all sides that
is kept clear of combustibles?
Ref: 1910.107(b)(9)
AVOIDANCE OF AIRBORNE
CONTAMINENTS
A properly working
ventilation system will
allow the avoidance of
time it takes to put on
the full body protection &
respirators. Ventilation
will prevent skin
absorption of hazardous
substances and
inhalation of fumes,
mists or vapors from
paints or solvents.
IN SUMMARY:

Have sufficient air flow to assure that the
sprayed particles are drawn into the filter
system.

Be able to filter almost 100% of the
particles over 10 microns to assure a clean
environment.

Have a carbon-type filter, preferably of
activated carbon granules, to filter odors.
TO ENSURE SAFE & EFFICIENT
OPERATION OF THE BOOTH:
INSPECT FILTERS MONTHLY.
 REPLACE FILTERS AS NEEDED.
 RECORD ANY ACTIONS TAKEN ON A
MONTHLY LOG.
 INITIAL ALL LOG ENTIRES.
**** ABOUT EVERY 90 SURFACE SPRAY
APPLICATIONS A FILTER WILL NEED
TO BE CHANGED.
