				protect employees exposed to the hazards created by welding, cutting, or
				brazing operations by personal protective equipment in accordance with the
				requirements of chapter 296-800 WAC, 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 you may employ are as follows:
(a) Except when engaged in light work, all
				welders should wear flameproof gauntlet gloves.
(b) Flameproof aprons made of leather, 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)
				Where there is exposure to sharp or heavy falling objects, or a hazard of
				bumping in confined spaces, you must use hard hats or head protectors
				.

For purposes of this section, mechanical
				ventilation must meet the following requirements:
(a) Mechanical ventilation must consist of
				either general mechanical ventilation systems or local exhaust
				systems.
(b) General mechanical
				ventilation must be of sufficient capacity and so arranged as to produce the
				number of air changes necessary to maintain welding fumes and smoke within safe
				limits, as defined in Part B of this chapter.
(c) Local exhaust ventilation must consist of
				freely movable hoods intended to be placed by the welder or burner as close as
				practicable to the work. This system must be of sufficient capacity and so
				arranged as to remove fumes and smoke at the source and keep the concentration
				of them in the breathing zone within safe limits as defined in Part B of this
				chapter.
(d) Contaminated air
				exhausted from a working space must be discharged into the open air or
				otherwise clear of the source of intake air.
(e) All air replacing that withdrawn must be
				clean and respirable.
(f) You must
				not use oxygen for ventilation purposes, comfort cooling, blowing dust from
				clothing, or for cleaning the work area.

Current through Register Vol. 24-14, July 15, 2024
(1) Before welding,
				cutting, or heating is commenced on any surface covered by a preservative
				coating whose flammability is not known, a test must be made by a competent
				person to determine its flammability. You must consider preservative coatings
				to be highly flammable when scrapings burn with extreme rapidity.
(2) You must take precautions to prevent
				ignition of highly flammable hardened preservative coatings. When coatings are
				determined to be highly flammable, you must strip them from the area to be
				heated to prevent ignition.
(3)
Protection against toxic preservative coatings:
(a) In enclosed spaces, you must strip all
				surfaces covered with toxic preservatives of all toxic coatings for a distance
				of at least 4 inches from the area of heat application, or you must protect the
				employees by air line respirators, meeting the requirements of Part C of this
				chapter.
