Celluloid is a flammable material. Its main component, nitrocellulose, is inherently flammable. It burns quickly and easily when exposed to open flames or high temperatures (above 150°C), and may also release toxic gases.
Observe the following safety precautions during use and storage:
Keep away from sources of fire and heat: Avoid exposure to open flames, heaters, ovens, and other high-temperature sources, and protect from prolonged direct sunlight.
Control the storage environment: Store in a cool, dry, and well-ventilated area. Avoid overcrowding and keep away from flammable materials (such as alcohol and gasoline).
Avoid mechanical friction: Celluloid products may produce sparks from friction or impact, so avoid violent collisions or crushing.
Prohibit unauthorized processing: Cutting, grinding, and other operations are not recommended (as frictional heat can cause combustion). Processing should be performed in a professional environment.
Dispose of aged products promptly: Aged and brittle celluloid products are more prone to breakage and flammability and should be properly disposed of promptly.
If softening, deformation, or an odor is observed during daily use, be aware of the safety risks and isolate them immediately.
