Note: The helmet and its cap must be compatible and designed for use together. For example, HDPE helmets should only be used with their corresponding caps. Failure to do so may reduce the helmet’s protective capabilities, potentially leading to serious injuries or even fatalities. Inspection Procedure Always inspect your helmet before and after each use. A thorough check ensures that it remains in good condition and continues to provide proper protection. Cap Shell Inspection 1. Examine the shell for cracks, dents, or any signs of damage.
2. If you notice any of these issues, do not use the helmet. Any damage to the shell compromises its structural integrity, making it unable to withstand impacts, penetration, or electrical shocks. Cap Liner Inspection 1. Check if the liner has lost elasticity or feels stiff.
2. Ensure the liner is intact—no tears, breaks, or peeling.
If any of these conditions are present, replace the liner immediately before using the helmet again. Helmet Maintenance Clean your helmet regularly with a mild soap (non-detergent) and warm water, or a suitable disinfectant. Keeping the helmet clean helps maintain hygiene and ensures it remains in optimal condition. Avoid throwing the helmet or using it as a support. Treat it with the same care as other essential safety equipment. Service Life Guidelines Although helmets are made from durable materials, they are not meant to last indefinitely. Regular inspections are crucial. Replace the helmet or any damaged parts as needed. Never risk your safety by extending its life beyond the recommended period.
The entire helmet should be replaced after 2.5 years of use. However, this is the maximum lifespan. If you detect any damage during routine checks, replace it immediately regardless of how long it has been in use.
In the event of a collision or penetration, replace the helmet immediately. These situations can significantly compromise its protective function. Note: Failing to follow these guidelines may result in severe injury or death. This helmet provides limited protection against impacts and penetration on the top of the head. It is not designed to protect against front, side, or back impacts. While it can help prevent injuries from small objects like tools, bolts, or rivets, some hazards may still cause serious harm. Always avoid areas where high-impact or penetrating risks exist.
Make sure the helmet is worn properly, with both the chin and head straps fastened for maximum protection. Do not place items like gloves, cigarettes, or earplugs between the liner and shell, as they can cause injury during impact.
Never use this helmet as a motorcycle or sports helmet. Always inspect the helmet before and after each use, and replace any worn or damaged components.
Do not exceed the service life outlined in these instructions. Replace parts or the entire helmet when necessary.
Do not alter or modify the helmet in any way. Avoid using paints, solvents, or hydrocarbon-based cleaners (such as MEK, thinners, gasoline, or kerosene), as they may cause hidden damage over time. China Labor Insurance Network Exterior Use High Speed Roller Doors
Exterior use High Speed Doors are designed for
outside doors of factory and warehouse, which will face wind pressure from outside.
Such exterior rapid doors need be reinforced to withstand big wind.
Normally, if such doors are made from PVC fabric, it must be supported with metal wind bars at the middle. And the high speed door can be aluminum material, to get biggest wind resistance.
