Common safety protective equipment inspection method

It is essential to thoroughly inspect and test all commonly used safety protective equipment before each use. A critical step involves checking the safety net for any debris, damage caused by falling objects, or damage from lifting activities. Additionally, after a helmet has been struck by an object, it should be inspected for cracks or other signs of impact damage. These inspections are usually carried out according to established protocols.

(1) Hard Hats: To ensure their effectiveness, hard hats must pass specific tests. One standard method involves dropping a 3kg steel ball from a height of 5 meters onto a semi-circular human head model. The helmet should not show any damage during the test. The internal elastic band should be properly fastened to the model. This testing method can be applied to hard hats made from various materials. It is recommended that hard hats be inspected annually to ensure continued reliability.

(2) Safety Belts: According to national regulations, factory tests for safety belts involve applying a load of 120kg and subjecting the belt to an impact from an overhead frame between 2 to 2.8 meters high. All components must remain intact and undamaged. In practice, construction companies often use sandbags, wood chips, and iron bars to simulate heavy loads during testing. Experiments may also include dynamic and static load tests on specially designed shelves. The tensile strength of nylon belt accessories typically includes: 1200–1500kg for the belt itself, 700–1000kg for the straps, 1500kg for the safety rope, 1200kg for the hook ring, 60kg for the fixed clip, and 700kg for the leg parts. Regular static load tests should be conducted on safety belts. The test load is 225kg, and it should be hung for 5 minutes to check for deformation or cracking. Records should be kept. Safety belts should be inspected before every use. New belts should be spot-checked after two years, and older ones should be sampled every six months. Importantly, any safety gear that has been tested should never be reused.

(3) General Inspection of Personal Protective Equipment (PPE): When evaluating PPE, several key factors should be considered:

• Ensure the product is manufactured by a company with a valid "production license."
• Verify that the product comes with a "product certificate."
• Confirm that the product meets the relevant quality standards.
• Check that the specifications and technical performance match the protection requirements of the task at hand.

By following these guidelines, workers can significantly reduce the risk of injury and ensure a safer working environment. Always prioritize proper inspection and maintenance of safety equipment to protect yourself and others on the job site.
