Compressed-Air Work Sites
Compressed-air work sites are sites where employees perform
duties in a pressurized environment, such as a caisson. Hazards
associated with compressed-air work are similar to hazards
found in diving operations, such as decompression sickness,
and in confined spaces. In addition, structural failures or
blowouts may occur, causing the work area to become inundated
with mud and water. Regulatory requirements for this type
of work are found in 1200 - 1280 (click
here for Compressed Air Safety Orders) and include the
following:
A. Cal/OSHA must receive written notification at least seven
days before the work is started. 1205(a)
B. Compression rates are prescribed in 1210(a).
C. Air lock requirements are discussed in 1220.
D. Decompression chamber requirements are noted in 1225.
E. Temperature, lighting, sanitation, and ventilation requirements
are discussed in 1230.
F. Compression plant, air supply, and communication requirements
are prescribed in 1240.
G. Medical attendance and examination requirements are noted
in 1280.
