Selection and Use
SCBAs will be used during certain maintenance activities or operations where other
respirator
protection is not adequate based on the toxicity and warning properties of the hazardous materials
(such as Isocyanates), or when responding to emergencies where:
•
The atmosphere presents an oxygen deficiency (less than 19.5% oxygen);
•
There is a concentration of a hazardous chemical that is immediately dangerous to life or health
(IDLH);
•
Where the hazardous substance, in certain atmospheres, lacks an adequate warning property (odor
or taste), or the identity or quantity of the substance is unknown and in the professional judgment
of the emergency responder, air concentrations may exceed that which could be adequately
protected from use of
negative pressure respirators
; and
•
It is deemed necessary by the emergency response personnel.
Normally the determination to use SCBA in an emergency shall be made by key facility personnel who
have attended EHS Emergency Response Training or trained EHS staff.
When such an emergency arises, authorized University personnel to affect rescue
or mitigate the
release of a hazardous material will wear SCBAs. All SCBA units used for emergency purposes will be
NIOSH
approved, open circuit/pressure demand, with a full-facepiece.
