    PROBLEM: PLASTIC SKYLIGHT BREAKING CAUSING INJURY

    Why are there so many injuries caused by roof maintenance workers falling through skylights and what can be done to keep workers safe?

    SOLUTION: UV STABILITY OR SOMETHING ELSE?

    Skylights are manufactured using clear or translucent plastic. Skylights are supposed to be manufactured to withstand the impact of a person falling against it without breaking.

    Unfortunately, unless plastics are properly stabilized against UV degradation, the plastic becomes brittle and will break if someone steps on it or falls against it.

    Plastic Expert Group are experts in plastic failure analysis. If you know someone was injured by falling through a skylight, we have worked on multiple cases in the past, and can determine the root cause of your skylight breaking.
