Mich. Admin. Code R. 408.40723 - Cylinders generally
Rule 723.
(1)
A chain, bracket, or other restraining device shall be used at all times to
prevent cylinders from falling.
(2)
A cylinder shall stand valve end up at all times.
(3) A cylinder shall not be dropped, dragged,
rolled on its side, or struck violently.
(4) When using a crane or hoisting device, a
cylinder shall be lifted only by cradles or enclosed platforms. An
electromagnet, hook, rope, or sling shall not be used.
(5) A frozen or ice-clogged valve shall be
thawed either by warm air or warm water and shall be dried before using.
Boiling water or a flame shall not be used. Force shall not be applied to a
valve or cap to loosen a cylinder frozen in place.
(6) Gases shall not be mixed within a
cylinder except by the supplier. Only the owner of the cylinder, if the owner
is qualified, or a person trained, qualified, and authorized by the owner,
shall refill a cylinder. The contents of a cylinder shall be used only for
those purposes intended by the supplier.
(7) A cylinder shall not be placed where it
will become a part of the electrical circuit by accidental grounding or where
it may be burned by an electric welding arc. A cylinder shall not be placed so
that hot slag or flame can reach it unless the cylinder is protected by a
fire-resistant shield. An electrode shall not be tapped against a cylinder to
strike an arc.
(8) A regulator,
gauge, or hose shall not be interchangeable between fuel gas, oxidizing gas, or
inert gas. Connections for compressed gas cylinders shall be as prescribed in
American National Standard Institute Standard ANSI/ASA B57.1, 1965 edition,
"Compressed Gas Cylinder Valve Outlet and Inlet Connections," which is adopted
by reference in
R
408.40709.
(9) A cylinder valve shall be opened slightly
for an instant and then closed before connecting to a regulator or manifold to
clear the valve of dust and dirt. The employee opening the valve shall stand to
one side of the outlet, not in front of it. The employee shall not open the
valve near a source of ignition. Pressure to a regulator shall be introduced by
slowly opening the cylinder valve. An acetylene cylinder valve shall only be
opened enough to allow proper working pressure, but shall not be opened more
than 1 1/2 turns of the spindle.
(10) Acetylene shall not be utilized or
piped, except in cylinder manifolds, at a pressure in excess of 15
psig.
(11) A cylinder to which a
regulator is attached shall not be moved unless secured to a hand or powered
truck designed or equipped for this purpose.
(12) A cylinder valve must be closed in any
of the following situations:
(a) When moving
the cylinder.
(b) When the work is
finished or is left unattended during the lunch period, overnight, or any other
prolonged period.
(c) When the
cylinder is empty.
(d) When the
regulator is removed.
(13) A cylinder without fixed handwheels
shall have keys, handles, or nonadjustable wrenches on valve stems while in
service. A multiple cylinder installation shall require only 1 key or handle
for each manifold.
A hammer shall not be used to open a cylinder valve or loosen a cap.
(14) A
cylinder, whether full or empty, shall not be used as a roller or
support.
(15) A damaged or a
leaking cylinder, a cylinder with a valve stuck open, or a valve in need of
repair shall be taken outdoors away from sources of ignition, tagged with a
warning sign, and the manufacturer or distributor notified. Complete removal of
the stem from the cylinder valve shall be avoided.
(16) Nothing shall be placed on top of the
cylinder.
