				  management on whose property cutting and welding is to be performed, see,
				  Standard for Fire Prevention in Use of Cutting and Welding Processes, NFPA
				  Standard 51B, 1962. The basic precautions for fire prevention in welding or
				  cutting work are:
(1)
Fire
				hazards.
If the object to be welded or cut cannot readily be moved, you
				must take all movable fire hazards in the vicinity to a safe place.
(2)
Guards.
If the object to be
				welded or cut cannot be moved and if all the fire hazards cannot be removed,
				then you must use guards to confine the heat, sparks, and slag, and to protect
				the immovable fire hazards.
(3)
Restrictions.
If the
				requirements stated in WAC
				296-24-69501(1) and
				(2)  cannot be followed then you must not
				perform welding and cutting.

Washington Administrative Code › Title 296 - Labor and Industries, Department of › Chapter 296-24 - General safety and health standards › Part I - WELDING, CUTTING AND BRAZING › Section 296-24-69503 - Special precautions

Current through Register Vol. 24-14, July 15, 2024
When the nature of the work to be performed falls within the
				  scope of WAC
				  296-24-69501(2)
				 certain additional precautions may be necessary:
(1)
Combustible material.
Wherever there are floor openings or cracks in the flooring that cannot be
				closed, you must take precautions so that no readily combustible materials on
				the floor below will be exposed to sparks which might drop through the floor.
				You must observe the same precautions with regard to cracks or holes in walls,
				open doorways and open or broken windows.
(2)
Fire extinguishers.
You must
				maintain suitable fire extinguishing equipment in a state of readiness for
				instant use. Such equipment may consist of pails of water, buckets of sand,
				hose or portable extinguishers depending upon the nature and quantity of the
				combustible material exposed.
(3)
Fire watch.
(a) Fire watchers
				must be required whenever welding or cutting is performed in locations where
				other than a minor fire might develop, or any of the following conditions
				exist:
(i) Appreciable combustible material,
				in building construction or contents, closer than 35 feet to the point of
				operation.
(ii) Appreciable
				combustibles are more than 35 feet away but are easily ignited by
				sparks.
(iii) Wall or floor
				openings within a 35-foot radius expose combustible material in adjacent areas
				including concealed spaces in walls or floors.
(iv) Combustible materials are adjacent to
				the opposite side of metal partitions, walls, ceilings, or roofs and are likely
				to be ignited by conduction or radiation.

Current through Register Vol. 24-14, July 15, 2024
(1)
Selection.
(a) You must use
				helmets or hand shields during all arc welding or arc cutting operations,
				excluding submerged arc welding.
Goggles should also be worn during arc welding or cutting
				  operations to provide protection from injurious rays from adjacent work, and
				  from flying objects. The goggles may have either clear or colored glass,
				  depending upon the amount of exposure to adjacent welding operations. You must
				  provide helpers or attendants with proper eye protection.
(b)You must use goggles or other suitable eye
				protection during all gas welding or oxygen cutting operations. Spectacles
				without side shields, with suitable filter lenses are permitted for use during
				gas welding operations on light work, for torch brazing or for
				inspection.
(c)All operators and
				attendants of resistance welding or resistance brazing equipment must use
				transparent face shields or goggles, depending on the particular job, to

Washington Administrative Code › Title 296 - Labor and Industries, Department of › Chapter 296-24 - General safety and health standards › Part I - WELDING, CUTTING AND BRAZING › Section 296-24-70005 - Protective clothing

Current through Register Vol. 24-14, July 15, 2024
(1)
General
				requirements.
You must protect employees exposed to the hazards created
				by welding, cutting, or brazing operations by personal protective equipment in
				accordance with the requirements of chapter 296-24 WAC, Part I, and WAC
				296-800-160. Appropriate
				protective clothing required for any welding operation will vary with the size,
				nature and location of the work to be performed.
(2)
Specified protective
				clothing.
Protective means which may be employed are as follows:
(a) Except when engaged in light work, all
				welders should wear flameproof gauntlet gloves.
(b)Flameproof aprons made of leather,
				asbestos, or other suitable material may also be desirable as protection
				against radiated heat and sparks.
(c)Woolen clothing preferable to cotton
				because it is not so readily ignited and helps protect the welder from changes
				in temperature. Cotton clothing, if used, should be chemically treated to
				reduce its combustibility. All outer clothing such as jumpers or overalls
				should be reasonably free from oil or grease.
(d)Sparks may lodge in rolled-up sleeves or
				pockets of clothing, or cuffs of overalls or trousers. It is therefore
				recommended that sleeves and collars be kept buttoned and pockets be eliminated
				from the front of overalls and aprons. Trousers or overalls should not be
				turned up on the outside.
Note: For heavy work, fire-resistant leggings, high boots, or
				  other equivalent means should be used.
(e) In production work a sheet metal screen
				in front of the worker's legs can provide further protection against sparks and
				molten metal in cutting operations.
(f) Capes or shoulder covers made of leather
				or other suitable materials should be worn during overhead welding or cutting
				operations. Leather skull caps may be worn under helmets to prevent head
				burns.
(g) For overhead welding and
				cutting, or welding and cutting in extremely confined spaces, ear protection is
				sometimes desirable.
(h) Where
				there is exposure to sharp or heavy falling objects, or a hazard of bumping in
				confined spaces, hard hats or head protectors must be used.

Current through Register Vol. 24-14, July 15, 2024
(1)
General.
As used herein confined space is intended to mean a
				relatively small or restricted space such as a tank, boiler, pressure vessel,
				or small compartment of a ship.
(2)
Ventilation.
Ventilation is a
				prerequisite to work in confined spaces. For ventilation requirements see WAC
				296-24-71501 through
				296-24-71525.
(3)
Securing cylinders and
				machinery.
When welding or cutting is being performed in any confined
				spaces you must leave the gas cylinders and welding machines on the outside.
				Before operations are started, you must securely block heavy portable equipment
				mounted on wheels to prevent accidental movement.
(4)
Lifelines.
Where a welder
				must enter a confined space through a manhole or other small opening, you must
				provide means for quickly removing the welder in case of emergency. When safety
				belts and lifelines are used for this purpose you must attach them in a manner
				so that the welder's body cannot be jammed in a small exit opening. An
				attendant with a preplanned rescue procedure must be stationed outside to
				observe the welder at all times and be capable of putting rescue operations
				into effect.
(5)
Electrode
				removal.
When arc welding is to be suspended for any substantial period
				of time, such as during lunch or overnight, you must remove all electrodes from
				the holders and carefully locate the holders so that accidental contact cannot
				occur and the machine disconnected from the power source.
(6)
Gas cylinder shutoff.
In
				order to eliminate the possibility of gas escaping through leaks or improperly
				closed valves, when gas welding or cutting, you must close the torch valves and
				positively shut off the fuel-gas and oxygen supply to the torch at some point
				outside the confined area whenever the torch is not to be used for a
				substantial period of time, such as during lunch hour or overnight. Where
				practicable you must also remove the torch and hose from the confined
				space.
(7)
Warning
				sign.
After welding operations are completed, the welder must mark the
				hot metal or provide some other means of warning other workers.
