Safety principles for welding and cutting operations at construction sites

While welding is a highly skilled trade that is essential to the construction process, it carries inherent risks and requires strict safety measures to ensure a safe working environment for welders. At the heart of these safety measures is the Welder's Ten Don'ts, a comprehensive guide to mitigating potential hazards associated with welding operations.

The Welder's Ten Don'ts include the following:

1. 
   1. No burning without obtaining a special welder's operation certificate: welders must hold a valid special welder operation certificate to perform welding operations.
2. 
   2. No burning without approval in high-risk and important places: before welding operations in dangerous or important places, corresponding approval must be obtained.
3. 
   3. No burning without understanding the surrounding conditions of the welding site: before starting the operation, welders must understand and confirm that the environment around the welding site is safe.
4. 
   4. No burning without understanding the internal conditions of the weld: before welding, welders need to know the internal structure of the weld to ensure safety.
5. 
   5. No burning if the container that has been filled with flammable and explosive items has not been thoroughly cleaned: if the container has been filled with flammable and explosive items, it must be thoroughly cleaned before welding.
6. 
   6. No burning in areas decorated with combustible materials: if the welding area is decorated with combustible materials, safety measures must be taken before welding.
7. 
   7. No burning in closed and pressurized containers and pipes: closed or pressurized containers and pipes are not allowed to be welded directly.
8. 
   8. No burning if there are flammable and explosive items near the welding area: if there are flammable and explosive items near the welding area, they must be removed or safety measures must be taken first.
9. 
   9. No welding if there is open flame nearby: If there is other open flame nearby, it may conflict with welding and should be avoided at the same time.
10. 
    10. No welding if no open flame approval is done in a fire-prohibited area: Before welding in a fire-prohibited area, open flame approval must be done.
11. 
    These principles are designed to ensure the safety of welders during welding operations and prevent accidents such as fire and explosion.
