Washington Administrative Code › Title 296 - Labor and Industries, Department of › Chapter 296-24 - General safety and health standards › Part G-3 - FIRE SUPPRESSION EQUIPMENT › Section 296-24-62203 - Specific requirements

Current through Register Vol. 24-14, July 15, 2024
(1) You must
				ensure that dry chemical agents are compatible with any foams or wetting agents
				with which they are used.
(2) You
				may not mix together dry chemical extinguishing agents of different
				compositions. You must ensure that dry chemical systems are refilled with the
				chemical stated on the approval nameplate or an equivalent compatible
				material.
(3) You must provide a
				predischarge employee alarm which will give employees time to safely exit from
				the discharge area prior to system discharge when dry chemical discharge may
				obscure.
(a)Your predischarge employee alarm
				systems must:
(i) Provide enough warning to
				allow employees to safely escape from the workplace or the immediate work area
				or both.
(ii) Be capable of being
				perceived above ambient noise or light levels by all employees in the affected
				portions of the workplace before system discharge.
(iii) Be distinctive and recognizable as a
				signal to evacuate the work area.
(iv) Be kept in operating condition except
				when undergoing repairs or maintenance.

Current through Register Vol. 24-14, July 15, 2024
(1)
Scope and application.
The
				requirements of this section apply only to dry chemical systems. These
				requirements are to be used in conjunction with the requirements of WAC
				296-24-617.
(2)
Maintenance.
The employer is
				responsible for assuring that dry chemical systems will operate effectively. To
				do this, periodic maintenance is necessary. One test that must be conducted
				during the maintenance check is one which will determine if the agent has
				remained free of moisture. If an agent absorbs any moisture, it may tend to
				cake and thereby clog the system. An easy test for acceptable moisture content
				is to take a lump of dry chemical from the container and drop it from a height
				of four inches. If the lump crumbles into fine particles, the agent is
				acceptable.

Washington Administrative Code › Title 296 - Labor and Industries, Department of › Chapter 296-24 - General safety and health standards › Part G-3 - FIRE SUPPRESSION EQUIPMENT › Section 296-24-62303 - Specific requirements

Current through Register Vol. 24-14, July 15, 2024
(1) You must
				ensure that agents used for initial supply and replenishment are of the type
				approved for the system's application. Carbon dioxide obtained by dry ice
				conversion to liquid is not acceptable unless it is processed to remove excess
				water and oil.
(2) You must ensure
				that except during overhaul, that the designed concentration of gaseous agents
				is maintained until the fire has been extinguished or is under
				control.
(3) You must ensure that
				employees are not exposed to toxic levels of gaseous agent or its decomposition
				products.
(4) You must ensure that
				the designed extinguishing concentration is reached within thirty seconds of
				initial discharge except for Halon systems which must achieve design
				concentration within ten seconds.
(5) You must provide a distinctive
				predischarge employee alarm capable of being perceived above ambient light or
				noise levels when agent design concentrations exceed the maximum safe level for
				employee exposure. A predischarge employee alarm for alerting employees before
				system discharge must be provided on Halon 1211 and carbon dioxide systems with
				a design concentration of 4% or greater, and for Halon 1301 systems with a
				design concentration of 10% or greater. The predischarge employee alarm must
				provide employees time to safely exit the discharge area prior to system
				discharge.
(6)
Halon
				1301:
(a)Where egress from an area
				cannot be accomplished within one minute, you must not use Halon 1301 in
				concentrations greater than 7%.
(b)
				Where egress takes greater than thirty seconds but less than one minute, you
				must not use Halon 1301 in a concentration greater than 10%.
(c) Halon 1301 concentrations greater than
				10% are only permitted in areas not normally occupied by employees provided
				that any employee in the area can escape within thirty seconds. You must ensure
				that no unprotected employees enter the area during agent discharge.
Washington Administrative Code › Title 296 - Labor and Industries, Department of › Chapter 296-24 - General safety and health standards › Part G-3 - FIRE SUPPRESSION EQUIPMENT › Section 296-24-62399 - Appendix A-Fixed extinguishing systems, gaseous agent

Current through Register Vol. 24-14, July 15, 2024
(1)
Scope and application.
This
				section applies only to those systems which use gaseous agents. The
				requirements of WAC
				296-24-617 also apply to the
				gaseous agent systems covered in this section.
(2)
Design concentrations.
Total
				flooding gaseous systems are based on the volume of gas which must be
				discharged in order to produce a certain designed concentration of gas in an
				enclosed area. The concentration needed to extinguish a fire depends on several
				factors including the type of fire hazard and the amount of gas expected to
				leak away from the area during discharge. At times it is necessary to
				"super-saturate" a work area to provide for expected leakage from the enclosed
				area. In such cases, employers must assure that the flooded area has been
				ventilated before employees are permitted to reenter the work area without
				protective clothing and respirators.
(3)
Toxic decomposition.
Certain
				halogenated hydrocarbons will break down or decompose when they are combined
				with high temperatures found in the fire environment. The products of the
				decomposition can include toxic elements or compounds. For example, when Halon
				1211 is placed into contact with hot metal it will break down and form bromide
				or fluoride fumes. The employer must find out which toxic products may result
				from decomposition of a particular agent from the manufacturer, and take the
				necessary precautions to prevent employee exposure to the hazard.

Current through Register Vol. 24-14, July 15, 2024
(1)
Scope and
				application.
This section applies to those systems that use water spray
				or foam. The requirements of WAC
				296-24-617 also apply to this
				type of system.
(2)
Characteristics of foams.
When selecting the type of foam for a
				specific hazard, the employer should consider the following limitations of some
				foams.
(a) Some foams are not acceptable for
				use on fires involving flammable gases and liquefied gases with boiling points
				below ambient workplace temperatures. Other foams are not effective when used
				on fires involving polar solvent liquids.
(b)Any agent using water as part of the
				mixture should not be used on fire involving combustible metals unless it is
				applied under proper conditions to reduce the temperature of burning metal
				below the ignition temperature. The employer should use only those foams that
				have been tested and accepted for this application by a recognized independent
				testing laboratory.
(c) Certain
				types of foams may be incompatible and break down when they are mixed
				together.
(d)For fires involving
				water miscible solvents, employers should use only those foams tested and
				approved for such use. Regular protein foams may not be effective on such
				solvents.
Whenever employers provide a foam or water spray system,
				  drainage facilities must be provided to carry contaminated water or foam
				  overflow away from the employee work area and egress routes. This drainage
				  system should drain to a central impounding area where it can be collected and
				  disposed of properly. Other government agencies may have regulations concerning
				  environmental considerations.

				  determine if protective clothing affords the required level of protection as
				  specified in chapter 296-811 WAC - fire brigades.
(1)
Puncture resistance test method for
				foot protection.
(a)
Apparatus.
You must perform the puncture resistance test on a
				testing machine having a movable platform adjusted to travel at
				one-quarter-inch per minute (0.1 cm/sec). You must prepare two blocks of
				hardwood, metal, or plastic as follows: The blocks must be of such size and
				thickness as to insure a suitable rigid test ensemble and allow for at least
				one-inch of the pointed end of an 8D nail to be exposed for the penetration.
				One block must have a hole drilled to hold an 8D common nail firmly at an angle
				of 98°. The second block must have a maximum one-half inch (1.3 cm)
				diameter hole drilled through it so that the hole will allow free passage of
				the nail after it penetrates the insole during the test.
(b)
Procedure.
You must place
				the test ensemble consisting of the sample unit, the two prepared blocks, a
				piece of leather outsole 10 to 11 irons thick and a new 8D nail, as follows:
				The 8D nail in the hole, the sample of outsole stock superimposed above the
				nail, the area of the sole plate to be tested placed on the outsole, and the
				second block with hole so placed as to allow for free passage of the nail after
				it passes through the outsole stock and sole plate in that order. You must
				start the machine and the pressure, in pounds required for the nail to
				completely penetrate the outsole and sole plate, recorded to the nearest 5
				pounds. You must make two determinations on each sole plate and the results
				averaged. A new nail shall be used for each determination.
