When required to wear head protection on a construction site, a worker must use a:
Explanation
Head protection must be of a type approved for the hazard, which in practice means a helmet meeting the current ANSI/ISEA Z89.1 standard - and the electrical class matters: Class E is tested to 20,000 volts, Class G to 2,200, and Class C offers no electrical protection at all. Each wrong answer degrades the shell. A bump cap (b) really is lighter and cooler and is built for walking into things, not for an object falling from a scaffold; it is not approved head protection. A metal shell (c) was the original hard hat and is conductive, which is why it left any site where electrical contact is possible. And drilling the shell for airflow (d) destroys the integrity the certification rests on and voids it.
