|
Mitigation is the process of making the incident less harsh, less hostil, less sever, less intense or painful, less destructive, to aleviate.
|
|
|
What are Booms.

|
|
Describe SAR s...
|
1. Supplied Air Respirators

|
|
Describe an SCBA ...
|
Self Contained Breathing Apperatus.
2 Offers protection against most types and levels of airborn contaminants but air supply is limited. Open circut scba is positive pressure and what is used by most fire fighters. Closed circuit SCBA in an apparatus that takes exhaled air and recycles it to remove CO2 and may add in more O2. These usually have 2 hoses going to the face mask. |
|
|
EPA CPC ppe Level A is..
|
the highest available protection for respiratory, skin and eye protection and requires a SCBA or SAR. Consists of a fully encapsulated suit and is used where vapor protection from gases is needed.
|
|
|
EPA CPC ppe Level B is..
|
a decreased level of protection but it still protects the skin, respiratory system from splashes and sprays and still requires a SCBA or SAR. it is nonencapsulated.
|
|
|
EPA CPC ppe Level C is
|
Another decrease in the level of protection but still good for splash or spray prtection in an environment with sufficient air supply to use a APR or an PAPR. more commonly used in an industrial site vs and emergency incident.
|
|
|
EPA CPC ppe Level D is..
|
The least protection, it is generally work clothes with or without respiratory protection.
