What safety precautions should be taken when temporarily repairing a cracked NGW-L gearbox housing?

Shut Down and Isolate: Immediately stop the equipment operation, cut off the power supply, and hang warning signs such as "Do Not Close" at the switch to prevent accidental activation.

Personal protection: Maintenance personnel must wear personal protective equipment such as safety helmets, protective goggles, and protective gloves; if working at heights, a safety harness must be fastened.

Preventing Fires and Explosions: Temporary repairs often involve welding or cleaning, requiring the work area to be free of open flames and flammable materials. If welding is necessary, oil stains must be thoroughly removed, and the interior cavity must be confirmed free of oil and gas residues before welding begins.

Prevention of burns and leaks: Avoid contact with high-temperature components of the reducer and freshly discharged lubricating oil to prevent burns; also, properly collect any leaked lubricating oil to prevent slippery floors and reduce the risk of personnel slipping.

Tool and Environmental Safety: Before starting work, inspect tools for damage and clear obstacles from the site. If using electric tools such as handheld grinders, check their insulation performance to prevent electric shock risks
