(1) Cylinders for compressed, liquefied or dissolved
gases shall be clearly marked by means of prescribed identifying colours,
have a clearly legible identification of the name and chemical formula
of their contents and be properly secured.
(2) Cylinders containing flammable or other dangerous
gases and expended cylinders shall be stored, properly secured, on
open decks and all valves, pressure regulators and pipes leading from
such cylinders shall be protected against damage. Cylinders shall
be protected against excessive variations in temperature, direct rays
of the sun, and accumulation of snow. However, the Administration
may permit such cylinders to be stored in compartments complying with
the requirements of paragraphs (3) to (5).
(3) Spaces containing highly flammable liquids,
such as volatile paints, paraffin, benzole, etc., and, where permitted,
liquefied gas, shall have direct access from open decks only. Pressure-adjusting
devices and relief valves shall exhaust within the compartment. Where
boundary bulkheads of such compartments adjoin other enclosed spaces
they shall be gastight.
(4) Except as necessary for service within the
space, electrical wiring and fittings shall not be permitted within
compartments used for the storage of highly flammable liquids or liquefied
gases. Where such electrical fittings are installed, they shall be
to the satisfaction of the Administration for use in a flammable atmosphere.
Sources of heat shall be kept clear of such spaces and No smoking
and No naked light notices shall be displayed in a prominent position.
(5) Separate storage shall b provided for each
type of compressed gas. Compartments used for the storage of such
gases shall not be used for storage of other combustible products
nor for tools or objects not part of the gas distribution system.
However, the Administration may relax these requirements considering
the characteristics, volume and intended use of such compressed gases.
