Self-Contained Breathing Apparatus

makes use of a hose to deliver clean, safe air  from a stationary source of compressed air
 
provides clean air for long periods of time and are light weight for the user
 
limits the range of user-mobility and may fail due to hose damage
 
also called  airline respirators
have an auxiliary self-contained air supply that can be used if the primary supply fails
 
the self-contained portion can be small since it only needs to supply enough air for escape
 
can be used for entry into confined spaces 
consists of a wearable, clean-air supply pack
 
do not restrict movement with a hose connection
 
the closed-circuit type can provide air up to 4 hours
 
the open-circuit type only provide air for 30 - 60 minutes
are normally used when there are extended work periods required in atmospheres that are not immediately dangerous to life and health (IDLH)
are normally used when there are extended work periods required in atmospheres that are or may be immediately dangerous to life and health (IDLH)
are normally used when there is a short-time need to enter and escape from atmospheres which are or may be immediately dangerous to life and health (IDLH)
bulletEmployers are required to provide employees using atmosphere-supplying respirators (supplied air and self contained breathing apparatus) with breathing gases of high purity, and shall ensure that compressed air, compressed oxygen, liquid air, and liquid oxygen used for respiration is in accordance with the specifications of OSHA Standard 1910.134(i).
