What Does
American National Standard For Industrial Head Protection Mean?
The American National Standard for Industrial Head Protection was originally established in 1986 with ANSI Z89.1-1986. It has since then gone through a number of updates. The standard states that affected employees must wear protective helmets in areas where there is the possibility of a falling object causing a head injury. If workers are in the vicinity of electrical conductors which may contact the head, they must wear a protective helmet that is designed to reduce electrical shock effects.
