Personal Protective Equipment
A respirator should ensure that the worker will not be exposed to the chemicals present above the applicable limits

Personal Protective Equipment
a worker has a high breathing rate
the ambient temperature is high or low
the worker has a poor facepiece to face seal
Any respirator can be compromised if:

Air - Purifying Respirators
selectively remove specific airborne contaminants
NOT for IDLH atmospheresuse only in atmosphere with
sufficient oxygen (19.5%)usually are a negative pressure

Air - Purifying Respirators
Warning properties are essential to safe use of air-purifying respirators since they allow detection of contaminant breakthrough should it occur.
14
Air - Purifying Respirators
Change your cartridges according to your employer’s change schedule
Do Not Wait for Contaminant Breakthrough to Replace Your Cartridges
If You Experience Contaminant Breakthrough, You Experience Exposure !
15
Self-Contained Breathing Apparatus
Employees engaged in emergency response to spills and releases and exposed to hazardous substances presenting an inhalation hazard or potential inhalation hazard shall wear positive pressure self-contained breathing apparatus (SCBA).
16
Self-Contained Breathing Apparatus
Escape Only SCBAsEntry and Escape SCBAs
open circuit - exhale to air closed circuit - exhale to
scrubber
17
Self-Contained Breathing Apparatus
Is atmosphere IDLH or likely to be?
Is duration of air supply sufficient?
Will bulk / weight of SCBA interfere with task?
Will temperature affect either SCBA or worker?
