Does this rule apply to me?
1910.123(a)(1)
This rule (§§1910.123
through 1910.126) applies when you use a dip tank containing a liquid
other than water. It applies when you use the liquid in the tank or its
vapor to:
1910.123(a)(1)(i)
Clean an object;
1910.123(a)(1)(ii)
Coat an object;
1910.123(a)(1)(iii)
Alter the surface of an object; or
1910.123(a)(1)(iv)
Change the character of an object.
1910.123(a)(2)
This rule also applies to the draining or drying of an object you have dipped or coated.
1910.123(b)
What operations are covered? Examples of covered operations are
paint dipping, electroplating, pickling, quenching, tanning,
degreasing, stripping, cleaning, roll coating, flow coating, and
curtain coating.
1910.123(c)
What operations are not covered? You are not covered by this rule if your dip-tank operation only uses a molten material (a molten metal, alloy, or salt, for example).
1910.123(d)
How are terms used in §§1910.123 through 1910.126 defined?
Adjacent area means any area within 20 feet (6.1 m) of a vapor area
that is not separated from the vapor area by tight partitions.
Approved means that the equipment so designated is listed or
approved by a nationally recognized testing laboratory, as defined by
§1910.7.
Autoignition temperature means the minimum temperature required to
cause self-sustained combustion, independent of any other source of
heat.
Combustible liquid means a liquid having a flash point of 100°
F (37.8° C) or above.
Dip tank means a container holding a liquid other than water and that is used for dipping or coating. An object may be immersed (or
partially immersed) in a dip tank or it may be suspended in a vapor
coming from the tank.
Flammable liquid means a liquid having a flashpoint below 100°
F (37.8° C).
Flashpoint means the minimum temperature at which a liquid gives off a vapor in sufficient concentration to ignite if tested in
accordance with the definition of "flashpoint" in §1910.1200(c).
Lower flammable limit (LFL) means the lowest concentration of a
material that will propagate a flame. The LFL is usually expressed as a
percent by volume of the material in air (or other oxidant).
Vapor area means any space containing a dip tank, including its
drain boards, associated drying or conveying equipment, and any
surrounding area where the vapor concentration exceeds 25% of the LFL
of the liquid in the tank.
You means the employer, as defined by the Occupational Safety and
Health Act of 1970 (29 U.S.C. 651 et seq.).
