Guidelines to avoid forming combustible mixtures
Avoid forming combustible mixtures by adhering to the following:
Do not admit flammable gases into an area that contains oxygen/air. Do not admit
oxygen/air into an area that contains flammable gases.
Maintain a small positive pressure in systems to prevent air from leaking into them when
the equipment is shut down.
Avoid venting of flammable gases through vents that do not contain an inert atmosphere.
Personal protective equipment required for use with pyrophoric and flammable gases is listed in
Chapter 1 Section 9.
Note that the personal protective equipment (PPE) for pyrophorics differs from
the flammables. Be sure to use the proper PPE.

1.10.4 Oxygen and Other Oxidizer Hazards
Systems using oxygen or other oxidizers
(i.e. nitrous oxide, fluorine) have specific
guidelines for specifying equipment, materials
of construction and system cleanliness. Failure
to comply with materials of construction and
system cleanliness could result in injury or
death.
