Life or Death Safety

The NFPA has identified the various FR hazardous risk category levels, which range from PPE 1 (which is low risk and requires AR clothing with a minimum arc rating of 4), up to PPE 4 (which is high risk and requires AR clothing with a minimum arc rating of 40). Each level, 1-4, is rated at a certain amount of flame resistance measured in cal/cm2.

Type/Class R2 apparel is necessary for workers exposed to traffic traveling over 25 mph and who work against complex backgrounds.

Class R3 apparel is intended for workers requiring the highest level of visibility, have high task loads and need to be visible throughout a full range of body motions.
