ACGIH
American Conference of Governmental
Industrial Hygienists.
Adjacent area
Any area within 20 feet (6.1 m) of a
vapor area that isn't separated from the vapor area by tight
partitions.
ANSI
American National Standards Institute.
Approved
Approved or listed by a nationally recognized
testing laboratory. Refer to federal regulation 29 CFR 1910.7,
for definition of nationally recognized testing laboratory.
Autoignition temperature
The minimum temperature required to
cause self-sustained combustion without any other source of
heat.
Combustible
liquid
A liquid having a flashpoint of at least
100°F (37.8°C) and below 200°F (93.3°C). Mixtures with at least
99% of their components having flashpoints of 200°F (93.3°C)
or higher aren't considered combustible liquids.
Detearing
A process for removing excess wet coating
material from the bottom edge of a dipped or coated object or
material by passing it through an electrostatic field.
Dip tank
A container holding a liquid other than
plain water 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
Any liquid having a flashpoint below
100°F (37.8°C), except any mixture having components with flashpoints
of 100°F (37.8°C) or higher, the total of which make up 99%
or more of the total volume of the mixture.
Flashpoint
The minimum temperature at which a liquid
gives off a vapor in sufficient concentration to ignite when
tested by any of the measurement methods described in the definition
of flashpoint in the Safety and Health Core Rules, WAC 296-800-370.
Lower flammable
limit
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).
NFPA
National Fire Protection Association.
Vapor area
Any area in the vicinity of dip tanks,
their drain boards or associated drying, conveying, or other
equipment where the vapor concentration could exceed 25% of
the lower flammable limit (LFL) for the liquid in the tank.
You
Means the employer. See the definition
of employer in the safety Safety and Health Core Rules, WAC
296-800-370.
