F-1. INTRODUCTION.

a. Confined space as defined in the glossary, Is su bject to the
accumulation of toxic or comubustible gases or the development of an oxygen
deficient or enriched atmosphere. Therefore, respiratory protection is
required when working in a confined space. The type of respiratory protective
equipment depends on the type of confined space encountered. See the glossary
for the definitions of oxygen deficient atmosphere, oxvoen enrichedatmosphere,
combustible atmosphere. toxic atmosphtre, immediately dangerous to life or
ealth (IDLHTatmosphere, and not immediately dangerous to life o-r e@a tF-
(NIDLH) atmosphere.

b. Confined spaces include, but are not limited to, storage tanks,
process vessels, bins, boilers, ventilation or exhaust ducts, sewers,

a. Employees will be instructed in the nature of the hazards involved,
the necessary precautions to be taken, and in the use of PPE and emergency
equipment required.

b. Prior to employee entry into areas where an IDLH is likely to occur,
appropriate tests of the atmosphere will be conducted to determine the oxygen
content, and If combustible gas or toxic levels have been exceeded. Testing
will be conducted in the above order prescribed.
