TERM DEFINITION

Flammable

A chemical that falls into one of the following categories:

• Aerosol, flammable means an aerosol that yields a flame projection

exceeding 18 inches at full valve opening, or a flashback (a flame

extending back to the valve) at any degree of valve opening,

• Gas, flammable means:

− ) A gas that, at ambient temperature and pressure, forms a flammable

mixture with air at a concentration of thirteen (13) percent by volume

or less, or

− A gas that, at ambient temperature and pressure, forms a range of

flammable mixtures with air wider than twelve (12) percent by volume,

regardless of the lower limit.

• Liquid, flammable means any liquid having a flash point below 100 deg.

F., except any mixture having components with flash points of 100 deg.

F. or higher, the total of which make up 99 percent or more of the total

volume of the mixture.

• Solid, flammable means a solid, other than a blasting agent or explosive

as defined in 1910.109(a), that is liable to cause fire through friction,

absorption of moisture, spontaneous chemical change, or retained heat

from manufacturing or processing, or which can be ignited readily and

when ignited burns so vigorously and persistently as to create a serious

hazard. A chemical shall be considered to be a flammable solid if it

ignites and burns with a self-sustained flame at a rate greater than one-

tenth of an inch per second along its major axis.

Flash point

The minimum temperature at which a liquid gives off a vapor in sufficient

concentration to ignite.

Hazardous chemical

Any chemical this is a physical hazard or a health hazard.

Hazard warning

Any words, pictures, symbols, or combination appearing on a label or other

appropriate form of warning which convey the specific physical and health

hazard(s), including target organ effects, of the chemical(s) in the

container(s). (See the definitions for physical hazard and health hazard to

determine the hazards which must be covered.)

Health hazard

A chemical for which there is evidence that acute or chronic health effects

may occur in exposed employees. The term health hazard includes

chemicals which are carcinogens, toxic or highly toxic agents, reproductive

toxins, irritants, corrosives, sensitizers, hepatotoxins, nephrotoxins, and

neurotoxins, agents which act on the hematopoietic system and agents

which damage the lungs, skin, eyes, or mucous membranes.

Identity

Any chemical or common name which is indicated on the material safety data

sheet (MSDS) for the chemical. The identity used shall permit cross-

references to be made among the required list of hazardous chemicals, the

label and the MSDS.

Immediate use

The hazardous chemical shall be under the control of and used only by the

person who transfers it from a labeled container and only within the work shift

in which it is transferred.
