Consolidated Requirements12

4.4.2.1 Smoking shall be permitted only in designated

NFPA 30, 5.-9.2

and properly identified areas.

4.4.2.2 Welding, cutting, and similar spark-producing

NFPA 30, 5.-9.3;

operations shall not be permitted in areas

containing flammable or combustible liquids

29CFR1910.106(e)(8)

until a written permit authorizing such work

has been issued.

4.4.2.3 All equipment (such as tanks, machinery, and

NFPA 30, 5.9.4;

piping) where an ignitable mixture could be

present shall be bonded or connected to a

29CFR1910.106(e)(6)(ii)

ground. The bond or ground or both shall be

physically applied or shall be inherently

present by the nature of the installation.

Electrically isolated sections of metallic

piping or equipment shall be bonded to the

other portions of the system or shall be

individually grounded.

4.4.332 Individual containers of flammable or combustible

29CFR1910.106(d)(2)(iii)

liquids shall not exceed the capacities listed in

29CFR1910.106, Table H-12.

4.4.4

In an office occupancy, containers of Class I liquids

NFPA 30, 4.5.5.2

that are outside of an inside liquid storage (see

definition) area shall not exceed a capacity of one

gallon (3.8 liters).

[EXCEPTION: safety cans (see definition) are

permitted up to a two-gallon capacity.]

4.4.5

In an office occupancy, not more than ten gallons (37.8

NFPA 30, 4.5.5.3

liters) of Class I and Class II liquids (see definition)

combined shall be kept in a single fire area (see

definition) outside of a storage cabinet or an inside

liquid storage area, unless the liquids are in safety cans

(see definition).

Glass or plastic containers up to one gallon in size may be used for Class IA or IB liquids if either (1) the liquid

would be rendered unfit for its intended use by contact with metal, (2) the liquid would corrode a metal container so

as to create a leakage hazard, (3) the process would require more than the allowed quantities of liquid of a single

assay lot to be used at one time, or (4) the process would require the maintenance of an analytical standard liquid of

a quality which is not met by the specified standards of liquids available, and the quantity of the analytical standard

liquid required for any one control process exceeds one-sixteenth the capacity of the container allowed under Table
