S. Hose and hose connection
1. Hose shall be capable of withstanding a hydrostatic pressure of fifty six
kilograms (56 kg) per square centimeter.
2. A single hose having more than one gas passage, a wall failure of
which would permit the flow of one gas into the other gas-passage,
shall not be used. Where two hoses joined by a web so as to form
integral lengths of double hose are used, the two hoses shall be
identified as follows:
a. By exterior color, such as by employing green for oxygen and red
for acetylene, or
b. If the entire exterior of both passages are of the same color, the two
sides shall be distinguished by feel or touch (i.e., smooth versus rib or
rough exterior surface).
3. When parallel lengths as oxygen and acetylene hoses are taped
together for convenience and to prevent tangling, not more than ten
centimeters (10 cm) shall be covered with tape.
4. Hose connections shall be clamped or otherwise securely fastened in
a manner that will withstand twice the pressure to which they are
normally subjected in service but in no case shall be less than a
pressure of twenty-one kilograms (21 kg) per square centimeters.
5. Hoses shall be inspected frequently for leaks, burns, torn places, loose
connections or other defects, which may render the hose unfit for
service. Where hose shows excessive wear or has been subjected to
flashbacks, it shall be inspected and tested at twice the normal
pressure to which it is subject in service but in no case at less than
fourteen kilograms (14 kg) per square centimeter before being
returned to service. Defective length or hose shall be discarded.
T. Containers for calcium carbide
Containers used for the storage of calcium carbide shall be of metal of
sufficient strength to insure handling without rupture, and shall be
provided with a screw top or its equivalent. They shall be of water tight
construction. Solder shall not be used on joints in such a manner that fire
would break open the package. Packages shall be marked “CALCIUM
CARBIDE IS DANGEROUS IF NOT KEPT DRY.”
U. Storage of calcium carbide in building
1. Storage of calcium carbide inside the building shall be in a dry
waterproof and well-ventilated location.
