Current through Register Vol. 24-14, July 15, 2024
Alternating tread-type stairs have a series of steps between
				  50 and 70 degrees from horizontal, attached to a center support rail in an
				  alternating manner so that a user of the stairs never has both feet at the same
				  level at the same time. (See Figure D-11 of this section.)
(1) You must ensure that alternating
				tread-type stairs are designed, installed, used, and maintained in accordance
				with approved manufacturer's specifications, and have the following:
(a) Stair rails on all open sides;
(b) Handrails on both sides of enclosed
				stairs;
(c) Stair rails and
				handrails of such configuration as to provide an adequate handhold for a user
				grasping it to avoid a fall;
(d) A
				distance of 17 to 24 inches between handrails;
(e) A minimum width of 22 inches
				overall;
(f) A minimum tread depth
				of 8.5 inches;
(g) A minimum tread
				width of 7 inches;
(h) A maximum
				rise of 9.5 inches to the tread surface of the next alternating tread;
				and
(i) Open risers if the tread
				depth is less than 9.5 inches (24 cm).

				  Specifications
This Appendix provides nonmandatory guidelines to assist
				  employers in complying with the requirements of Part J-2 of this chapter. An
				  employer may use these guidelines and tables as a starting point for designing
				  scaffold systems. However, the guidelines do not provide all the information
				  necessary to build a complete system, and the employer is still responsible for
				  designing and assembling these components in such a way that the completed
				  system will meet the requirements of WAC 296-24-86010(1). Scaffold components
				  which are not selected and loaded in accordance with this Appendix, and
				  components for which no specific guidelines or tables are given in this
				  Appendix (e.g., joints, ties, components for wood pole scaffolds more than 60
				  feet in height, components for heavy-duty horse scaffolds, components made with
				  other materials, and components with other dimensions, etc.) must be designed
				  and constructed in accordance with the capacity requirements of WAC
				  296-24-86010(1), and loaded in accordance with WAC 296-24-86010(4)(a).

Corrosion or pitting.
Corrosion or pitting in
				  cylinders involving the loss of wall thickness by corrosive media.
Note: There are several kinds of pitting or corrosion to be
				  considered.
Cuts, gouges, or digs (in cylinders).
Deformations caused by contact with a sharp object in such a way as to cut into
				  or upset the metal of the cylinder, decreasing the wall thickness at that
				  point.
Dents (in cylinders).
Deformations caused by the
				  cylinder coming in contact with a blunt object in such a way that the thickness
				  of metal is not materially impaired.
DOT.
The U.S. Department of
				  Transportation.
General corrosion.
Corrosion which covers
				  considerable surface areas of the cylinder.
Note: It reduces the structural strength. It is often
				  difficult to measure or estimate the depth of general corrosion because direct
				  comparison with the original wall cannot always be made. General corrosion is
				  often accompanied by pitting.
High- and low-pressure cylinders.
Those
				  cylinders with a marked service pressure of 900 p.s.i. or greater; low-pressure
				  cylinders are those with a marked service pressure less than 900 p.s.i.
Isolated pitting.
Isolated pits of small
				  cross-section which do not effectively weaken the cylinder wall but are
				  indicative of possible complete penetration and leakage.
Note: Since the pitting is isolated the original wall is
				  essentially intact.
Line corrosion.
Pits which are not isolated but
				  are connected or nearly connected to others in a narrow band or line.
Note: This condition is more serious than isolated pitting.
				  Line corrosion frequently occurs in the area of intersection of the footring
				  and bottom of a cylinder. This is sometimes referred to as "crevice
				  corrosion."
Minimum allowable wall thickness.
The minimum
				  wall thickness required by the specification under which the cylinder was
				  manufactured.

Washington Administrative Code › Title 296 - Labor and Industries, Department of › Chapter 296-24 - General safety and health standards › Part K - COMPRESSED GAS AND COMPRESSED GAS EQUIPMENT › Section 296-24-92003 - General requirements

Current through Register Vol. 24-14, July 15, 2024
(1)
Application.
(a) You must
				determine that compressed gas cylinders under the employers control are in a
				safe condition to the extent that this can be determined by visual, and other
				inspection required by WAC
				296-24-920 through
				296-24-92011.
(b) The requirements contained in these
				standards are not intended to apply to cylinders manufactured under
				specification DOT (ICC)-3HT (49 C.F.R. Ch.1). Separate requirements covering
				service life and standards for visual inspection of these cylinders are
				contained in Compressed Gas Association Pamphlet C-8, "Standard for
				Requalification of ICC-3HT Cylinders."
Washington Administrative Code › Title 296 - Labor and Industries, Department of › Chapter 296-24 - General safety and health standards › Part K - COMPRESSED GAS AND COMPRESSED GAS EQUIPMENT › Section 296-24-92005 - Inspection of low-pressure cylinders exempt from the hydrostatic test including acetylene cylinders

Current through Register Vol. 24-14, July 15, 2024
(1)
Application.
This section covers cylinders of the type that are
				exempt from the hydrostatic retest requirements of the DOT by virtue of their
				exclusive use in certain noncorrosive gas service. They are not subject to
				internal corrosion and do not require internal shell inspection.
(2)
Preparation for inspection.
You must remove rust, scale, caked paint, etc., from the exterior surface so
				that the surface can be adequately observed. You must provide facilities for
				inverting the cylinder to facilitate inspection of the bottom. This is
				important because experience has shown this area to be the most susceptible to
				corrosion.
(3)
Exterior
				inspection.
You must check cylinders as outlined below for corrosion,
				general distortion, or any other defect that might indicate a weakness which
				would render it unfit for service.
(a) To fix
				corrosion limits for all types, designs, and sizes of cylinders, and include
				them in this section is not practicable. Cylinders categorized by this section
				and subsection (1) of this section must meet the following requirements.
				Failure to meet any of these requirements is of itself cause for rejection of a
				cylinder. You must remove rejected cylinders from the work place. Rejected
				cylinders may be returned to the manufacturer for reinspection.
(i) You must reject a cylinder when the tare
				weight is less than 95% of the original tare weight marked on the cylinder.
				When determining tare weight, be sure that the cylinder is empty.
(ii) You must reject a cylinder when the
				remaining wall in an area having isolated pitting only is less than 1/3 of the
				minimum allowable wall thickness as determined under (b) and (d) of this
				subsection.
(iii) You must reject a
				cylinder when line corrosion on the cylinder is 3 inches in length or over and
				the remaining wall is less than 3/4 of the minimum allowable wall thickness or
				when line corrosion is less than 3 inches in length and the remaining wall
				thickness is less than 1/2 the minimum allowable wall thickness as determined
				under (b) through (d) of this subsection.
(iv) You must reject a cylinder when the
				remaining wall in an area of general corrosion is less than 1/2 of the minimum
				allowable wall thickness as determined under (b) through (d) of this
				subsection.
Washington Administrative Code › Title 296 - Labor and Industries, Department of › Chapter 296-24 - General safety and health standards › Part K - COMPRESSED GAS AND COMPRESSED GAS EQUIPMENT › Section 296-24-92007 - Low-pressure cylinders subject to hydrostatic testing

Current through Register Vol. 24-14, July 15, 2024
(1)
Application.
Cylinders
				covered in this section are low-pressure cylinders other than those covered in
				WAC 296-24-92005 through
				296-24-92005(3)(o)(ii).
				They differ essentially from such cylinders in that they require a periodic
				hydrostatic retest which includes an internal and external examination. Defect
				limits for the external examination are prescribed in WAC
				296-24-92005 through
				296-24-92005(3)(o)(ii),
				with exceptions for aluminum cylinders shown in WAC
				296-24-92007(4).
(2)
Preparation for inspection.
You must purge flammable gas cylinders before being examined with a light.
				Lamps used for flammable gas cylinder inspection must be explosion
				proof.
(3)
Internal
				inspection.
You must inspect cylinders internally at least every time
				the cylinder is periodically retested. You must perform the examination with a
				light of sufficient intensity to clearly illuminate the interior
				walls.
(4)
External
				inspection of aluminum cylinders.
The inspection requirements of WAC
				296-24-92005 through
				296-24-92005(3)(o)(ii)
				 must be met, except as follows:
(a) You must
				reject aluminum cylinders when impairment to the surface (corrosion or
				mechanical defect) exceeds a depth where the remaining wall is less than
				three-fourths of the minimum allowable wall thickness required by the
				specification under which the cylinder was manufactured.
(b) You must remove aluminum cylinders
				subjected to the action of fire from service.

				service pressure of 900 p.s.i. or higher. They are seamless; no welding is
				permitted. The great bulk of such cylinders are of the 3A or 3AA types under
				DOT specifications (49 C.F.R. Ch. 1).
(2)
Preparation for inspection.
(a) You must clean cylinders for inspection
				so that the inside and outside surfaces and all conditions can be observed.
				This must include removal of scale and caked paint from the exterior and the
				thorough removal of internal scale. You must examine cylinders with interior
				coating for defects in the coating. If the coating is defective, you must
				remove it.
(b) A good inspection
				light of sufficient intensity to clearly illuminate the interior wall is
				mandatory for internal inspection. You must purge flammable gas cylinders
				before being examined with a light. Lamps for flammable gas cylinder inspection
				must be explosion proof.
Washington Administrative Code › Title 296 - Labor and Industries, Department of › Chapter 296-24 - General safety and health standards › Part K - COMPRESSED GAS AND COMPRESSED GAS EQUIPMENT › Section 296-24-92011 - Internal inspection

Current through Register Vol. 24-14, July 15, 2024
(1) You must
				ensure that cylinders are inspected internally at least every time the cylinder
				is periodically retested. This examination must be made with a light of
				sufficient intensity to clearly illuminate the interior walls.
(2) A hammer test consists of tapping a
				cylinder a light blow with a suitably sized hammer. A cylinder, emptied of
				liquid content, with a clean internal surface, standing free, will have a clear
				ring. Cylinders with internal corrosion will give a duller ring dependent upon
				the amount of corrosion and accumulation of foreign material. You must
				investigate such cylinders . The hammer test is very sensitive and is an easy,
				quick, and convenient test that can be made without removing the valve before
				each charging. It is an invaluable indicator of internal corrosion.
