Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) Spraying shall not be conducted outside
						of predetermined spraying areas and all provisions of this Section applying to
						spraying areas shall be strictly followed.
(b) High pressure hose conveying flammable or
						combustible material in "airless" spray application operations shall be
						frequently inspected and properly maintained. Hose and equipment shall be so
						located that in the event of a leak or rupture, application material will not
						be discharged into any space having a source of ignition.
(c) All spraying areas shall be kept free
						from the accumulation of deposits of combustible residues. If residue
						accumulates to excess in booths, duct or duct discharge points or other
						spraying areas, then all spraying operations shall be discontinued until
						conditions are corrected.
NOTE: Combustible coverings (thin paper, plastic, etc.)
						  and strippable coatings may be used to facilitate cleaning operations in spray
						  areas.
(d) Spray booths,
						spray rooms and similar locations shall be thoroughly cleaned of combustible
						deposits on floors, walls, ceilings, and equipment before any repairs involving
						the use of torches, electric arcs or sparks, or other source of ignition are
						undertaken.
(e) Scrapers, spuds or
						other such tools used for cleaning purposes shall be of non-sparking
						material.
(f) Residue scrapings and
						debris contaminated with residue shall be immediately removed from premises and
						properly disposed of.
(g)
						Self-closing, hinged, metal waste cans shall be provided wherever rags or waste
						are impregnated with sprayed material and all such rags or waste shall be
						deposited therein immediately after use. The contents of waste cans shall be
						properly disposed of at least once daily or at the end of each shift.
(h) Employees' clothing contaminated with
						sprayed material shall not be left on the premises overnight unless kept in
						metal lockers.
(i) Solvents for
						cleaning operations shall have flash points above 100° F, however, for
						cleaning spray nozzles and auxiliary equipment, solvents having flash points
						not less than those normally used in spray operations may be used.
(j) Cleaning operations using flammable or
						combustible solvents shall be conducted inside spray booths with ventilating
						equipment operated during cleaning or in other adequately ventilated
						locations.
(k) Spray booths shall
						not be alternately used for different types of coating materials, where the
						combination of materials may be conducive to spontaneous ignition, unless all
						deposits of the first used material are removed from the booth and exhaust
						ducts prior to spraying with the second.
(l) Unless spray booths are thoroughly
						cleaned before changing operations, booths used for application of pyroxylin
						finishes shall not be used for other purposes.
(m) Smoking shall be prohibited except in
						designated localities. "NO SMOKING" signs shall be conspicuously posted where
						hazard from flammable vapors may be reasonably expected.
