There are 4 levels of protection as designated by the Occupational Safety and Health Administration (OSHA) for Hazardous Materials (HAZMAT) workers. The levels are Level A, Level B, Level C and Level D. The hierarchy of protection levels ranges from the most protective level (Level A) to the least protective level (Level D). Depending upon the hazardous substance(s) encountered, the level of protection will be assigned. The site-specific Health and Safety Plan (HASP) must list the proper level of protection as well as other key information. The level of protection must adequately protect a worker from any biological, physical or chemical hazard.
This level of protection features a fully encapsulated vapor protection suit (full body protection) pressure demand full face Self-Contained Breathing Apparatus (SCBA), inner chemical resistant gloves, chemical resistant safety boots and two way radio communication.
Protection Provided: This ensemble provides the highest available level of respiratory, skin, and eye protection from hazardous substances in a solid, liquid or gaseous phase.
Level A is utilized when hazardous substances have been identified and have a high level of hazards to the respiratory system, skin and eyes. The substances present when using this level of protection are usually known or suspected to cause skin toxicity or carcinogenity. An example of an operation using this level of protection is entering a permit required confined space.
