C. Material that contains more than
0.010% asbestos.
D. Material that contains more than
.001% asbestos.
A. Material that contains more than
1.000% asbestos.
ACM = asbestos-containing material
(any material containing more than one percent asbestos)
When must a contractor provide and require the use of protective clothing?
A. When Class-Il work requires removal of ACM exceeding 10 square feet.
B. When airborne exposure exceeds the
TWA and excursion limits.
C. When Class-II work requires removal of TSI exceeding 25 linear feet.

ACM = asbestos-containing material
(any material containing more than one percent asbestos).
TWA = time-weighted average. No
emplovee may be exposed to an airborne concentration of asbestos greater than
0.1 fiber per cubic centimeter of air as an eight-hour time-weighted average.
TSI - thermal system insulation, meaning ACM that has been applied to pipes, fittings, boilers, breeching, tanks, ducts, or other structural components to prevent heat loss or gain
Class-II work = activities involving the
removal of ACM that are not thermal system insulation or surfacing material.
These include, but are not limited to, the removal of asbestos-containing wallboard, foor tile and sheeting, roofing and siding shingles, and construction mastics.
EL = excursion limit. No employee may
be exposed to an airborne concentration of asbestos greater than one fiber per cubic centimeter of air (1 f/cc) as averaged over a sampling period of thirty minutes,

The “2A? rating refers to the size of the extinguisher. For Class A, the rating is for a fixed amount of water (1-1/4 gallons).
So 2A = 2 × 1-1/4 gallons of water, or 2-1/2 gallons. That means this extinguisher is just as effective as 2-1/2 gallons of water.
