Hazard factors and risk tips for pipe threading lathes

(1) hazard factors

1. Dangerous and harmful factors of machinery

(1) The blade of the stationary cutting tool, the mechanical processing equipment protrudes the longer part of the machine, and the working platform that causes sliding and falling causes injury to the personnel;

(2) Longitudinal, transverse, and through the movement of the work table lead to personnel injury.

(3) Getting involved in rotating mechanical parts and causing injuries to personnel.

(4) Flying out of the cutting, workpiece, tool, parts resulting in personnel injury.

(5) The equipment is damaged due to dry friction caused by not filling lubricating grease in time.

2. Non-mechanical hazards and harmful factors

(1) Electric shock damage is caused by poor insulation, wrong connection or wrong operation of the electrical part of the equipment.

(2) Harmful static electricity, explosion and electric shock caused by mechanical processing.

(3) It is burned by high temperature metal body and workpiece during hot working, causing injuries to personnel.

(4) During machining, the vibration is transmitted to the operator through the vibration tool, the vibration machine or the vibration workpiece, causing injury to personnel.

(5) Injuries caused by mechanical noise caused by mechanical impact, friction and rotation, fluid dynamic noise caused by sudden gas pressure or fluid flow, and electro-magnetic noise caused by the interaction of alternating forces in the motor.

(6) The dust produced by the mechanical processing or crushing of solid materials causes injuries to personnel.

(2) Risk presentation

1. Before starting the mechanical equipment, check whether reasonable and reliable safety protection devices are installed. If they do not meet the safety requirements, make Suggestions for rectification in time.

2. Check whether there is any sign of serious wear and tear on the parts, and replace and maintain the parts in time when found.

3. Operators shall wear labor protection articles in accordance with regulations during operation.

4. When the equipment is in operation, it is strictly prohibited to adjust and measure the workpiece by hand or to lubricate, remove sundries or wipe the equipment.

5. Cut off the power of the maintenance parts according to the actual situation, and check and confirm with the intact multimeter or side pen.

6. Before maintenance, it shall know the matters needing attention in this work, the operation procedure of maintenance and repair, and the staff shall concentrate their thoughts, wear in line with safety requirements, and stand in a safe position.

7. It is strictly prohibited to wipe the equipment with inflammable and volatile articles. Oily rags should not be placed on the equipment, and inflammable and explosive articles should not be placed around the equipment.
