Garments compliant to HRC (Hazard Risk Category) 2, as defined by NFPA 70E, 2009 edition, have an arc rating that is greater than or equal to 8 cal/cm², but is less than 25 cal/cm². HRC 2 may also be called Level 2. In some cases, incorrectly, users may refer to HRC 2 as Class 2. Class 2 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. Garments compliant to HRC 2 are often referred to as daily wear. Daily wear includes, but is not limited to, knit or button front FR shirts, work pants or FR jeans and coveralls. NOTE: Not all daily wear is compliant to hazard risk category 2. Be sure to check the arc rating to confirm that the garment will provide the necessary protection.
