HRC 3

Return to Glossary

Garments compliant to HRC (Hazard Risk Category) 3, as defined by NFPA 70E, 2009 edition, have an arc rating that is greater than or equal to 25 cal/cm², but are less than 40 cal/cm².

Finding flame resistant clothing compliant to HRC 3 may be more difficult than Levels 2 and 4. Level 2 flame resistant clothing is daily wear: work shirts, work pants, jeans and coveralls. HRC / Level 4 clothing is for higher voltage applications. Arc flash kits, arc flash hoods and outerwear make up most of level 4. It is often more cost effective to purchase HRC/Level 4 instead of HRC/Level 3 clothing. Look at the options of moving up a level when considering arc flash kits or gear.

HRC 3 may also be called Level 3. In some cases, incorrectly, users may refer to HRC 3 as Class 3. Class 3 applies to ANSI standards, and other standards, but not to NFPA 70E. HRC and Level are correct identifiers. To ensure correct communication of a need, use the arc rating.
