Acetylene Cutting and Welding Safe Operating Procedures

• Cylinders, cylinder valves, couplings, regulators, hose, and apparatus must be kept
  free from oily or greasy substances.
• Oxygen cylinders or apparatus must not be handled with oily hands or gloves.
• A jet of oxygen must never be permitted to strike an oily surface, greasy clothes, or
  enter a fuel oil or other storage tank.
• When transporting cylinders by a crane or derrick, a cradle, boat, or suitable platform
  shall be used. Slings or electric magnets shall not be used for this purpose.
• Valve-protection caps, where cylinder is designed to accept a cap, must always be in
  place.
• Cylinders must not be dropped or struck or permitted to strike each other violently.
  Valve-protection caps must not be used for lifting cylinders from one vertical position
  to another.
• Bars must not be used under valves or valve-protection caps to pry cylinders loose
  when frozen to the ground or otherwise fixed; the use of warm (not boiling) water is
  recommended.
• Valve-protection caps are designed to protect cylinder valves from damage.
• Unless cylinders are secured on a special truck, regulators must be removed and
  valve-protection caps, when provided for, must be put in place before cylinders are
  moved.
• Cylinders not having fixed hand wheels must have keys, handles, or nonadjustable
  wrenches on valve stems while these cylinders are in service. In multiple cylinder
  installations only one key or handle is required for each manifold.
• Cylinder valves must be closed before moving cylinders.
• Cylinder valves must be closed when work is finished.
