Current through Register Vol. 24-14, July 15, 2024
(1)
Conformance.
The storage of flammable liquids with a flashpoint
				  greater than 199.4°F (93°C) in connection with spraying operations must
				  conform to the requirements of WAC
				  296-24-330, where
				  applicable.
(2)
Quantity.
The quantity of flammable liquids or liquids with a
				  flashpoint greater than 199.4°F (93°C) kept in the vicinity of spraying
				  operations must be the minimum required for operations and should ordinarily
				  not exceed a supply for one day or one shift. Bulk storage of portable
				  containers of flammable liquids or liquids with a flashpoint greater than
				  199.4°F (93°C) must be in a separate, constructed building detached
				  from other important buildings or cut off in a standard manner.
(3)
Containers.
You must use
				  original closed containers, approved portable tanks, approved safety cans or a
				  properly arranged system of piping for bringing flammable liquids or liquids
				  with a flashpoint greater than 199.4°F (93°C) into spray finishing
				  room. You must not use open or glass containers.
(4)
Transferring liquids.
Except
				  as provided in subsection (5) of this section, the withdrawal of flammable
				  liquids and liquids with a flashpoint greater than 199.4°F (93°C) from
				  containers having a capacity of greater than 60 gallons must be by approved
				  pumps. You must only perform the withdrawal of flammable liquids or liquids
				  with a flashpoint greater than 199.4°F (93°C) from containers and the
				  filling of containers, including portable mixing tanks, in a suitable mixing
				  room or in a spraying area when the ventilating system is in operation. You
				  must take adequate precautions to protect against liquid spillage and sources
				  of ignition.
(5)
Spraying
				  containers.
Containers supplying spray nozzles must be of closed type or
				  provided with metal covers kept closed. Containers not resting on floors must
				  be on metal supports or suspended by wire cables. Containers supplying spray
				  nozzles by gravity flow must not exceed 10 gallons capacity. Original shipping
				  containers must not be subject to air pressure for supplying spray nozzles.
				  Containers under air pressure supplying spray nozzles must be of limited
				  capacity, not exceeding that necessary for one day's operation; must be
				  designed and approved for such use; must be provided with a visible pressure
				  gage; and must be provided with a relief valve set to operate in conformance
				  with the requirements of the Code for Unfired Pressure Vessels, Section VIII of
				  the ASME Boiler and Pressure Vessel Code-1968. Containers under air pressure
				  supplying spray nozzles, air-storage tanks and coolers must conform to the
				  standards of the Code for Unfired Pressure Vessels, Section VIII of the ASME
				  Boiler and Pressure Vessel Code-1968 for construction, tests, and
				  maintenance.
(6)
Pipes and
				  hoses.
(a) You must provide all
				  containers or piping to which is attached a hose or flexible connection with a
				  shutoff valve at the connection. You must keep such valves shut when spraying
				  operations are not being conducted.
(b) When a pump is used to deliver products,
				  you must provide automatic means to prevent pressure in excess of the design
				  working pressure of accessories, piping, and hose.
(c) You must inspect all pressure hose and
				  couplings at regular intervals appropriate to this service. You must test the
				  hose and couplings with the hose extended, and using the "inservice maximum
				  operating pressures." You must withdraw any hose showing material
				  deteriorations, signs of leakage, or weakness in its carcass or at the
				  couplings, from service and repaired or discarded.
(d) Piping systems conveying flammable
				  liquids or liquids with a flashpoint greater than 199.4°F (93°C) must
				  be of steel or other material having comparable properties of resistance to
				  heat and physical damage. You must properly bond and ground systems.
