Polycarbonate helmets that have been exposed to hydraulic oil should be?

Polycarbonate helmets are designed to provide protection, but exposure to hydraulic oil can significantly compromise their structural integrity. Hydraulic oil can degrade the material, weakening it and making it less effective in protecting the wearer in hazardous situations. The concern is that even if the helmet appears to be intact, the internal damage may not be visible and could lead to failure in the event of an impact.

Taking the helmet out of service ensures that it will not be used when needed, preventing the potential for injury. It’s essential to prioritize safety and be cautious with any gear that has been exposed to substances that could alter its physical properties. Other options, such as repairing or reusing the helmet after cleaning, do not guarantee the necessary safety standard required for protective gear and could put the user at risk. Moreover, while inspecting for cracks is important for maintenance, the presence of hydraulic oil indicates that the helmet's overall integrity may already be compromised, thus making removal from service the safest choice.
