4.3.8 No stack of flammable or combustible liquids shall be closer

NFPA 30, 4.4.3.9;

than 3 ft. to the nearest beam, chord, or other construction, and

shall be 3 ft. below sprinkler deflectors, discharge orifices of

29CFR1910.106(d)(5)

water spray, or other overhead fire protection systems.

(vi)(e)

4.3.9 Suitable fire control devices shall be available at locations where

NFPA 30, 4.9;

flammable and combustible liquids are stored.

29CFR1910.106(d)(7)

(i)

4.3.10 At least one portable fire extinguisher having a rating of not less

29CFR1910.106(d)(7)

than 40-B units shall be located outside but not more than 10 ft.

(i)(a);

from any door to a flammable and combustible liquids storage

29CFR1910.106(d)(7)

room or any area where Class I or Class II liquids are stored.

(i)(b)

4.3.11 Water reactive materials (see definition) shall not be stored in

NFPA 30, 4.10.1;

the same area with flammable or combustible liquids.24

29CFR1910.106(d)(7)

(iv)

4.3.12 Class I and Class II liquids in plastic containers shall only be

NFPA 30, 4.5.2.3

stored in flammable liquids storage rooms (see definition) or

flammable liquid storage cabinets.

4.3.13 Liquids used for building maintenance, painting, or other similar

NFPA 30, 4.5.1.3

infrequent maintenance purposes shall be permitted to be stored

temporarily in closed containers outside of flammable liquids

storage cabinets or flammable liquids storage areas, if the

amount stored does not exceed a 10-day supply at anticipated

use rates.

This requirement is intended to protect water reactive chemicals from exposure to water in water based fire

suppression systems that may be used where flammable liquids are stored. Spraying water on a water reactive

material during an upset condition could increase the severity and danger of the upset condition. While not required,

consideration should be given to applying a similar restriction in oxidizer storage areas. See section 4.4.2.
