What kind of materials are typically not suitable for machine guards?

Flammable materials or those that deteriorate easily are unsuitable for machine guards due to safety and durability concerns. The primary purpose of machine guards is to provide a protective barrier between operators and moving parts of machinery, and using materials that can easily catch fire or degrade over time can compromise that safety. For instance, if a guard were to deteriorate, it could lead to gaps or weaknesses, increasing the risk of injury. Similarly, the presence of flammable materials poses a significant fire hazard in an industrial environment, especially in scenarios where sparks or heat may be produced. Hence, materials selected for machine guards must be robust and able to withstand the operational environment without degrading or posing additional risks.
