Current through Register 2024 Notice Reg. No. 38, September 20, 2024
NOTE: This section refers to the use of bulk
nitrocellulose or scrap nitrocellulose film for the manufacture of lacquer or
other similar products. This material is not as highly nitrated as guncotton
and is usually shipped wet with alcohol, other organic liquids or water.
(a) Buildings and Equipment.
(1) All buildings or rooms having more than
100 square feet of area or where the maximum possible distance to the exit
exceeds 12 feet in which nitrocellulose is stored, processed, or handled shall
have at least two exits, remote from each other and so arranged that there are
no dead ends where a person might be trapped. Access to such exits shall not be
blocked or impeded.
(2)
Nitrocellulose shall not be stored or processed in a basement.
(3) All rooms wherein nitrocellulose is
stored, handled or processed shall be cleaned as often as necessary to prevent
accumulation of nitrocellulose on floors, ledges, beams, equipment, machines,
or elsewhere. Floors shall be free of cracks where nitrocellulose might
accumulate.
(4) Mechanical
equipment, including pulleys and shafting shall be of metal and shall be
electrically grounded. (See Electrical Safety Orders for regulations governing
electrical installation.)
(b) Storage.
(1) Nitrocellulose shall be stored in a
location remote from mixing and processing operations, preferably in a separate
fireproof building. Out-door storage is not recommended but may be permitted,
subject to local fire inspection, provided that the location is reasonably well
isolated and not exposed to flame, sparks, or combustible material. Containers
shall not be exposed to direct sunlight or stored near steam coils or other
sources of heat. Rooms or buildings used for storage shall be heated indirectly
so that no source of ignition will be present from this source. In heated
buildings, the distance between containers and heating units shall be such as
to prevent the metal of the container from rising above the temperature of the
room itself, and heaters shall be so arranged that drums cannot, under any
circumstances, come in contact with them.
(2) Nitrocellulose in storage shall be kept
wet with solvent or water. All containers shall be inspected before being put
in storage, and frequent inspection of drums in storage shall be made; if any
are found on which closures are not tight, solvent or water shall be added if
necessary and closure shall be tightened.
(3) Containers of nitrocellulose shall not be
opened in a storage building.
(c) Handling.
(1) Nonferrous tools and equipment shall be
used to open and handle drums of nitrocellulose, and where nitrocellulose is
present in open containers. Trucks used to carry nitrocellulose shall have
non-ferrous wheels. Rubber-tired wheels, unless conductive rubber is used, are
not recommended on account of the static hazard.
(2) Operations shall be arranged so that
nitrocellulose does not have an opportunity to dry out. All full or partially
full barrels or drums shall be kept tightly covered when not in use.
(3) All open containers in which
nitrocellulose or nitrocellulose lacquers are handled or processed shall be
electrically grounded. When such materials are transferred from one container
to another, the containers shall be bonded electrically before the transferring
is started.
(4) Empty barrels shall
be wiped clean (rags wet with water or solvent may be used) and closed as soon
as emptied.
(d) General.
(1) Quick-acting deluge showers and fire
blankets shall be provided and all employees shall be informed of their
location and how to use them.
(2)
Employees shall not wear clothing which has an accumulation of flammable
material on it.
(3) Rags, refuse,
sweepings, and other waste shall be kept in covered containers, wet down with
water, and disposed of at least once a day by burning in a safe
location.
(4) Matches, cigarette
lighters, and other similar sources of ignition shall be prohibited in any room
in which nitrocellulose is used, handled or stored. (Title 24,
