Any gas, in addition to those listed above,
used in the GASGUARD® system could
potentially displace the oxygen in the air
and cause asphyxiation.
1.10.6 Pressurized Gases
Pressurized gas lines could injure personnel
and damage equipment. Never tighten or
loosen a fitting when it is under pressure.
The process and purge gas cylinders can contain pressures up to 2650 psig in the USA. In Europe,
cylinders can contain pressures up to 200 barg. A leak from a loose mechanical fitting, component or a
ruptured/failed component can expose the operator to a high pressure gas stream or projectile.
Read
the cylinder handling warnings in Chapter 1 Section 1.10.7 and the safety literature on cylinder
handling in Chapter 1 Section 13
.
The house nitrogen supply lines can contain pressures of 100+ psig (7+ barg). Exercise care when
working around these lines. Insure that pressure has been vented before breaking any connection. Tag
out and lock out the line before doing any work.
Follow Typical Minimal Lockout or Tagout System
Procedures described by Occupational Safety and Health Admin., Labor Para. 1910.147 found in
Section 1.11.
1.10.7 Cylinder Handling Hazards
High pressure gas cylinders could be
extremely hazardous when not handled
properly.
Proper training, maintenance, leak testing and mechanical connection procedures can prevent operators
from being exposed to high pressure gas streams.
Use the cylinder change out procedures in Chapter
8 Section 8.3.2, "Process Cylinder Procedures."
