required by Title 49, Part 192, of the
U.S. Code of Federal Regulations, by
the national Fuel Gas Code Title 54 of
the national Fire Codes of the national
Fire Protection association or by other
applicable codes) to prevent service
conditions from exceeding those
limits. a regulator should be inspected
immediately for damage after any
overpressure condition.
additionally, physical damage to the
gas blanketing regulator could result in
personal injury and property damage
due to escaping accumulated gas. To
avoid such injury and damage, install
the gas blanketing regulator in a safe
and well ventilated location.
