For SI units, 1 ft = 0.3 m; 1 ft 2 = 0.09 m 2. ( 1 )
If the locker is provided with a fire resistance rating of not less
than 4 hours and deflagration venting is not required in accordance
with 6.4.2.4, all distances required by Table 6.6.4 shall be permitted
to be waived. ( 2 ) Site area limits are intended to differentiate the
relative size and thus the number of lockers that are permitted in one
designated site. ( 3 ) Distances applies to properties that have protection
for exposures, as defined. If there are exposures and such protection
does not exist, the distances shall be doubled. ( 4 ) When the exposed
building has an exterior wall, facing the designated site, that has
a fire-resistance rating of at least 2 hrs. and has no openings to above-grade
areas within 10 ft (3 m) horizontally and no openings to below-grade
areas within 50 ft (15 m) horizontally of the designated area, the distances
can be reduced to half of those shown in the table, except they shall
never be less than 5 ft (1.5 m). ( 5 ) When a single locker has a gross
single story floor area that will require a site area limit of greater
than 1500 ft 2 (139 m2) or when multiple units exceed the area limit
of 1500 ft 2. (140 m2), the authority having jurisdiction shall be consulted
for approval of distances.
6.6.4.1 Once the designated site is approved, it shall
not be changed without the approval of the authority having jurisdiction.
6.6.4.2 More than one locker shall be permitted on
a designated site, provided that separation distance between individual
lockers is maintained in accordance with Table 6.6.4.
6.6.4.3 Where the approved designated storage site
is accesible to the general public, it shall be protected from tampering
or trespassing. 6.6.4.4 Storage Practices.
6.6.4.4.1 Containers of liquid in their original shipping
packages shall be permitted to be stored either palletized or solid
piled. Unpackaged containers shall be permitted to be stored on shelves
or directly on the floor of the locker. Containers over 30 gal. (114
L) capacity storing Class I or Class II liquids shall not be stored
more than two containers high. In all cases, the storage arrangement
shall provide unrestricted access to and egress from the locker.
6.6.4.4.2 No other flammable or combustible materials
storage shall be permitted within the designated site approved for lockers.
6.6.4.4.3 Placarding or warning signs for lockers shall be in accordance
with applicable local, state, and federal regulations or with NFPA 704,
Standard System for the Identification of the Hazards of Materials for
Emergency Response.
HAZARD COMMUNICATION STANDARD OSHA 29 CFR 1910.1200(g)(8):
The employer shall maintain in the workplace copies of the required
material safety data sheets for each hazardous chemical, and shall ensure
that they are readily accessible during each work shift to employees
when they are in their work area(s). (Electronic access, microfiche,
and other alternatives to maintaining paper copies of the material safety
data sheets are permitted as long as no barriers to immediate employee
access in each workplace are created by such options)
