Faulty judgment
Insensitivity to pain
Abnormal emotions
Remove any personnel in an oxygen deficient atmosphere to fresh air.
Get medical attention
immediately.
Positive pressure breathing apparatus must be worn by any rescuers entering a
suspected oxygen deficient atmosphere.
Nitrogen gas may accumulate in low or confined areas. All requirements of OSHA 1910.146
(Confined Space Guidelines) must be met when inert gases may be present in confined spaces. Self
contained breathing apparatus is required (cartridge or filter type gas masks cannot be used). See the
information on personal protective equipment in this section for details.
When entering a confined area or area which may contain high inert gas concentrations, a
"Buddy
System"
must be used. One person should remain outside the suspect area, but within view of the
other person. This method ensures that the other person can respond in the event of an emergency.
1.4
Pressurized Fluids / Gases
Pressurized gas and water sprinkler lines
can injure personnel and damage
equipment. Never tighten or loosen a fitting
when it is under pressure.
The house nitrogen supply lines can contain pressures of 100+ psig (6.9+ barg). The water sprinkler
lines contain pressures of 30 psig (2.1 barg). Exercise care when working around these lines. Ensure
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.
