Levels of Chemical Protection
In Hazardous Material operations there are four levels
of protection.
•Level A
•Level B
•Level C
•Level D
Level A
Fully encapsulating suit with self-contained
breathing apparatus
Level B
Self-contained
breathing
apparatus,
Chemical
protective
clothing,
gloves, and
hard hat
Level C
Air-purifying
respirator,
chemical
protective
clothing, gloves,
boots, and hard hat
Level D
Chemicalprotective
clothing, boots,
gloves, and hard
hat
Level A
Level A should be worn when the highest level of respiratory,
skin, and eye protection is required.
Level A is used when:
•Conditions are unknown
•The hazardous substance has been identified and requires the
highest level of protection for skin, eyes, and respiratory system
•Operations are being conducted in confined, poorly ventilated
areas
•Work function involves a high potential for splash, immersion, or
exposure to unexpected skin hazards
LEVEL B
Should be selected when the highest level of respiratory
protected is needed and some degree of skin protection is
required. Level B is the minimum recommendation for initial
site entry.
Level B protection is used when:
•Air contaminants are unknown
•Air contaminants have been identified and the criteria for
using APRs are not met
•IDLH air concentrations exist
•The atmosphere contains less than 19.5% oxygen
•Direct contact does not pose a severe skin hazard
LEVEL C
Level C should be selected when types of airborne
contaminants are known, the concentrations are measured
and the criteria for using air-purifying respirators (APRs)
are met.
Level C protection is used when:
•Criteria for the use of APRs are met
•Air contaminants have been identified and concentrations
measured
•Direct contact does not pose a skin hazard
LEVEL D
Level D should not be worn on any site with
respiratory or skin hazards. Level D is primarily a
work uniform providing minimal protection.
Level D protection is worn when:
•Atmosphere contains no known hazards
•Work functions precludes the potential for
unexpected exposure to hazardous levels of any
substances
