Installation
Personal injury, equipment damage
or leakage due to escaping gas or
bursting of pressure-containing parts
might result if these regulators are
overpressured or installed where service
conditions could exceed the limits for
which the regulators were designed,
SEP
or where conditions exceed any
ratings of the adjacent piping or piping
connections. To avoid such injury or
damage, provide pressure-relieving or
pressure-limiting devices (as required
by the appropriate code, regulation or
standard) to prevent service conditions
from exceeding those limits.
Additionally, physical damage to a
regulator could cause personal injury
and property damage due to escaping
gas. To avoid such injury and damage,
install the regulator in a safe location.
A regulator may vent some gas to the
atmosphere in hazardous or flammable
gas service, vented gas might
accumulate and cause personal injury,
death or property damage due to fire or
explosion. Vent a regulator in hazardous
gas service to a remote, safe location
away from air intakes or any hazardous
location. The vent line must be protected
against condensation or clogging.
