Thinking Question
What level of protection does your current standard PPE offer you?
4.6 Respiratory Protection
Respiratory Protection is critical for first responders. Many CBRN materials are
undetectable to the human senses and can affect people most acutely through
inhalation. Many different respiratory systems exist, ranging from the maximal protection
offered by SCBA, to minimal protection offered in paper filtered dust masks.
Responders must be trained in the use of their respiratory equipment and must remain
diligent to use it only within its limitations. Respirators and filters should be specifically
tested and approved for CBRN agents.
As discussed earlier in this chapter, responders must use an All Hazards Approach
when considering PPE. As applied to respiratory protection, it must be assumed that
dangerous levels of CBRN materials exist, at least until appropriate and comprehensive
agent detection can be conducted. Only specialized responders equipped with Level A
suits, complete with SCBA, have adequate protection to work in unknown environments.
Responders with less than this level of protection should use the protection equipment
they have and remain at a safe distance. Chapter 5 will outline how perimeters and
hazard zones are established. Generally, respiratory protection requirements are linked
to these zones.
The respiratory protection provided by gas masks and filter systems can be adequate
but this depends on analysis of the contamination and proper use of equipment in
accordance with established zones.
4.7 Risks of Operating in PPE at CBRN Incidents
PPE does not provide protection without a cost. Wearing protective clothing can be
very taxing on responders. It is important to understand that the response to a CBRN
incident can extend over a long period of time. Some protective equipment is designed
to address traditional emergencies that are most often handled over a short time period.
