(1)
Scope and application. This rule applies to all pipes and piping systems that
contain hazardous substances, transport substances in a hazardous state, or
that use asbestos as insulation material. This rule does not apply to buried
pipe.
(2) Definitions:
(a) Asbestos: includes chrysoltile, amosite,
crocidolite, tremolite asbestos, anthophyllite asbestos, actinolite asbestos
and any of these minerals that have been chemically treated or altered.
(b) Hazardous substances: any
substance that is a physical or health hazard.
(c) Health hazard: A chemical that is
classified as posing one of the following hazardous effects: acute toxicity
(any route of exposure); skin corrosion or irritation; serious eye damage or
eye irritation; respiratory or skin sensitization; germ cell mutagenicity;
carcinogenicity; reproductive toxicity; specific target organ toxicity (single
or repeated exposure); or aspiration hazard. The criteria for determining
whether a chemical is classified as a health hazard are detailed in Appendix A
to 1910.1200 - Health Hazard Criteria, in Division 2/Z.
(d) Physical hazard: A chemical that is
classified as posing one of the following hazardous effects: explosive;
flammable (gases, aerosols, liquids, or solids); oxidizer (liquid, solid or
gas); self-reactive; pyrophoric (liquid or solid); self-heating; organic
peroxide; corrosive to metal; gas under pressure; or in contact with water
emits flammable gas. The criteria for determining whether a chemical is
classified as a physical hazard are detailed in Appendix B to 1910.1200 -
Physical Hazard Criteria, in Division 2/Z.
(e) Piping system: includes single or
multiple pipes of any kind in addition to valves and pipe coverings.
(3) Labeling.
(a) Label pipes that contain hazardous
substances or transport substances in a hazardous state according to (A), (B),
(C) and (D) below or otherwise identify them according to (3)(b) below:
(A) Positive identification of the hazardous
contents of pipe must be by lettered labels. The label must give the name of
the contents in full or abbreviated form.
(B) The label must identify the contents with
enough detail to identify the hazard.
(C) Label wording must be brief, informative
and simple.
(D) Use stenciling,
tape, adhesives, markers or effective alternative means for labels.
NOTE: Substances "transported in a hazardous
state" typically refer to the hazards of pressure and temperature. Examples
include compressed air, hot water or steam, and cryogenic liquids or
gases.
(b) The
employer may use an alternative warning method, instead of affixing labels to
individual pipes, if that method identifies the pipe(s) to which the warning
applies and conveys the hazard information required by this rule. Examples
include signs, placards, process sheets, or schematics posted on walls in the
work area; or other such written materials. These alternative written materials
must be readily accessible to the employees in their work areas during each
shift.
NOTE: See OAR
437-004-9800(5)
Labels and other forms of warning for other related requirements.
(c) Label pipes or piping systems
that use asbestos insulation material to include the following statements:
(A) DANGER CONTAINS ASBESTOS FIBERS
MAY CAUSE CANCER DO NOT BREATHE DUST AVOID CREATING DUST
(B) Or, otherwise identify
them according to (3)(b), above.
NOTE: See OAR
437-004-9800, Hazard
Communication for Agricultural Employers and OAR
437-004-9050, Asbestos, for
additional requirements.
(4) Location of labeling.
(a) Place the labeling near valves or
flanges; adjacent to changes in direction or branches; where pipes pass through
walls, floors or ceilings; and where confusion about the contents of the piping
system may occur.
(b) Labeling
must be applied, at a minimum, at the beginning and end of continuous pipe
runs.
(c) For asbestos insulation,
labeling on unobstructed continuous pipe runs must be at least every 75 feet.
(5) Visibility.
(a) Where pipes are located above or below
the normal line of vision, put the lettering below or above the horizontal
centerline of the pipe, to facilitate visibility.
(b) If pipes are inaccessible, or at a
distance that makes clear identification of the letters on a label difficult,
use alternatives to labeling that meet all other requirements of this
rule.
