Section 1: Safety Warnings
Revision - November 2004 Page 1 - 21
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.
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 1.10.
1.9.7 Electrical Hazards
Electric shock could cause personal injury
or death.
The control circuits for the system use 115/220 VAC, 50/60 Hz. Do not attempt to
work on the system without first turning the power off and tagging out and locking
out the electrical supply disconnect switch per plant lock out procedures.
Follow
the Typical Minimal Lockout or Tagout System Procedures described by
Occupational Safety and Health Admin., Labor Para. 1910.147 found in Section
1.10 of this manual.
1.9.8 Purge Gas Backstream Hazard
Avoid low pressure condition in purge gas
cylinder to prevent a backstream hazard.
The purge gas system incorporates a pressure indicating gage which will provide
the means of displaying a low purge gas cylinder pressure condition (usually 200
psig [14 barg] minimum). The cylinder should be changed out at this point to
prevent process gas from backstreaming into the purge gas cylinder.
