HRC HAZARD RISK CATEGORIES
The HRC (Hazard Risk Category) is established by the
minimum amount of calories per square centimetre (ATPV or
Cal/cm2). Any garment or garment set tested must result with
a 50% probability of a 2nd or 3rd degree burn occurring to the
wearer. The higher the result, expressed in ATPC or Cal/cm2,
the higher the HRC level achieved.
HRC Rating
ICONS EXPLAINED
There are five risk levels of 0, 1, 2, 3, 4 and 5. Level 0 is
where there is little or no risk, and level 4 is an highest or
most dangerous level of risk. The chart below shows the 5
levels, with typical garments for each level, typical layering
requirements and the minimum ARC rating requirements
for each category.

NFPA 70E
This is the standard for Electrical Safety in the Workplace,
created by the National Fire Protection Agency in the United
States. It was the first nationally recognized standard for
electrical safety in the USA and was first released in 1976
in partnership with OSHA to help provide agreement on
electrical safety standards. There have been several revisions
over the years and it continues to be a document that ensures
working areas that are safe from unacceptable risk.
