The Four Levels of Personal Protection Equipment

The Four Levels of

Personal Protection Equipment

Personal protective equipment is divided into four categories based on the degree of protection needed per incident circumstances.

 

 

Ø  Level A PPE: Highest level of protection should be worn when the highest level of respiratory, skin, eye and mucous membrane protection is needed. A typical Level A ensemble includes:

 

                  RESPIRATORY:

o    Positive pressure (pressure demand), full-face, self-contained breathing apparatus (SCBA) (NIOSH approved), or positive pressure supplied air respirator with escape SCBA.

                  SKIN/FACE

o    Fully encapsulating vapor and liquid chemical-resistant suit. (Imagine the classic hazmat suit.)

o    Gloves, inner, chemical resistant.

o    Gloves, outer, chemical resistant.

o    Hard hat under suit

                  BOOTS

o    Boots, chemical resistant covers, steel toe and shank; (depending on suit boot construction, worn over or under suit boot.)

 

Ø  Level B PPE: High level of protection  should be selected when the highest level of respiratory protection is needed, but a lesser level of skin and eye protection is needed. Level B protection is the minimum level recommended on initial site entries until the hazards have been further identified and defined by monitoring, sampling, and other reliable methods of analysis, and equipment corresponding with those findings utilized. A typical Level B ensemble includes:

 

                  RESPIRATORY:

o    Positive pressure (pressure demand), full-face, self-contained breathing apparatus (SCBA) (NIOSH approved), or positive pressure supplied air respirator with escape SCBA

SKIN/FACE:

o    Chemical resistant clothing (overalls and long-sleeved jacket, coveralls, hooded two-piece chemical splash suit, disposable chemical resistant coveralls.)

o    Full face shield w/ goggles underneath

o    Gloves, outer, chemical resistant.

o    Gloves, inner, chemical resistant.

o    Hard hat under suit

                  BOOTS

o    Chemical-resistant, steel-toed boots

o    Chemical-resistant outer boot cover

 

Ø  Level C PPE: Mid-level protection  should be selected when the type of airborne substance is known, concentration measured, criteria for using air-purifying respirators met, and skin and eye exposure is unlikely. Periodic monitoring of the air must be performed. A typical Level C ensemble includes:

 

                  RESPIRATORY:

o    Full-face or half-mask, air-purifying respirator (NIOSH approved).

     SKIN/FACE:

o    Chemical resistant clothing (one piece coverall, hooded two-piece chemical splash suit, chemical resistant hood and apron, disposable chemical resistant coveralls.)

o    Optional Hard Hat

o    Gloves, outer, chemical resistant.

o    Gloves, inner, chemical resistant. 

                  BOOTS

o    Chemical-resistant, steel-toed boots

o    Chemical-resistant outer boot cover

 

Ø  Level D PPE: Minimal protection, dependent on situation is primarily a work uniform and is used for nuisance contamination only. It requires only coveralls and safety shoes/boots. Other PPE is based upon the situation (types of gloves, etc.). It should not be worn on any site where respiratory or skin hazards exist.

 

                  RESPIRATORY:

o    Optional mask, largely dependent on the situation

     SKIN/FACE:

o    Safety glasses or goggles

o    Splash-resistant gown or overalls

o    2 layers of latex gloves

o    Optional hard hat

 

                  BOOTS

o    Safety boots with steel toe

o    Optional splash resistant outer boot cover

 


 

These are the 4 basic PPE levels as outlined by OSHA and the Centers for Disease Control and Prevention (CDC). Bio One of Knoxville Metro treats each trauma scene or biohazard remediation scene respectfully and approaches the work of with utmost safety. This is to protect not only our technicians, but also the surrounding environment and the inhabitants of the home or business.
