The heavy tower is a structure used in construction projects to support heavy loads and provide stability.

• Heavy towers are typically made of steel or concrete to withstand the weight of equipment and materials.

• They are often used in conjunction with cranes to lift and move heavy objects.

• Heavy towers play a crucial role in ensuring the safety of workers and the success of construction projects.

TPI stands for Threads Per Inch, a measurement used in manufacturing and engineering to determine the number of threads on a screw or bolt.

• TPI is calculated by counting the number of threads within a one-inch length on a screw or bolt.

• Higher TPI values indicate finer threads, while lower TPI values indicate coarser threads.

• TPI is an important factor in determining the compatibility of nuts and bolts in mechanical assem

A work permit system is a formal written system used to control certain types of work that are potentially hazardous.

• Work permit systems ensure that proper precautions are taken before high-risk work is carried out.

• They typically involve a written permit that must be obtained before work begins.

• Examples of work permit systems include hot work permits, confined space entry permits, and excavation permits.

The lifting work system refers to the process and procedures in place for safely lifting and moving heavy objects in the workplace.

• Involves assessing the weight and size of the object to be lifted

• Determining the appropriate lifting equipment to use

• Ensuring proper lifting techniques are followed to prevent injuries

• Training employees on safe lifting practices

• Implementing protocols for team lifts when necessary

Welding work hazards include exposure to fumes, gases, radiation, and electrical hazards.
