What factor can compromise the protective capability of a safety helmet?

The correct answer is that exposure to chemicals can degrade materials, thereby compromising the protective capability of a safety helmet. Safety helmets are typically made from materials such as polycarbonate, fiberglass, or other polymers, which can be vulnerable to the effects of certain chemicals. When a helmet comes into contact with aggressive substances—like solvents, acids, or oils—the material may weaken, lose its structural integrity, or become more brittle. This degradation can create vulnerabilities in the helmet's ability to absorb impact or resist penetration, directly impacting its protective function in hazardous work environments.

Understanding this factor is critical for ensuring safety in workplaces where exposure to chemicals is a risk. The maintenance of the helmet, including its cleaning and storage methods, should take into consideration the types of substances it may encounter. Regular inspections for signs of wear or damage are also essential in ensuring that the protective capabilities of the helmet remain intact.
