Concept of mechanical processing

Cold metal working is often called mechanical processing. In mechanical processing, the part is manufactured by cutting off excess material to achieve the correct size and gloss according to technical requirements. When working, occupational accidents can occur more or less depending on the type of machine, machine layout, workplace layout, ventilation, lighting, etc.

Definition of hazards in mechanical processing

Hazards in mechanical processing are places and sources of danger due to the shape, size, and movement of working equipment as well as machined parts that cause injury to workers. The level of injury depends on the energy of the impact system (such as equipment…) and the impact energy of the person (such as hand movement). From there, assess the impact of the hazard.

Accidents and common causes

Types of accidents in mechanical processing

In mechanical processing, accidents can be divided into the following types:

– Tripping

– Collapse, collision

– Electric shock

– Chip burns

– Chips flying into the eyes

– Puncture

– Clothes, hair caught in the machine

– Clamping, rolling, cutting machines

Causes of accidents

Some causes of accidents:

– Unsafe shielding equipment

– Lack of protective equipment, damaged or malfunctioning protective equipment

– Damaged machine control unit

– Violation of standards and procedures for safe machine use

– Violation of factory safety regulations

– Poor hygiene conditions such as: poor ventilation, lack of light, etc.

– Unfavorable traffic in the factory, messy factory floor

– Untidy arrangement of raw materials and finished products

Principles of safety in mechanical processing

General principles

– Fully implement the requirements on occupational safety and hygiene currently prescribed in all stages

– Identify dangerous areas and risks causing occupational accidents during the use of mechanical processing machinery

– Organize the factory floor to be suitable for safety conditions

– Arrange the factory, warehouse and transportation routes reasonably and conveniently

– Install equipment in the factory to ensure safety conditions

Safety principles when using machines and equipment

– No one except the person in charge is allowed to start the machine control

– Before starting the machine, check the safety equipment and standing position

– Before doing other work, turn off the machine, do not let the machine operate without the operator

– Turn off the power switch when there is a power outage

– When you want to adjust the machine, turn off the engine and wait for the machine to stop completely, do not use your hands or a stick to stop the machine

– When operating the machine, wear appropriate personal protective equipment

– Check the machine regularly and check before operating

– On a broken machine, hang a sign saying “Broken Machine”

Notes to make the machine safer and more productive

– Choose machines that are safe to operate

– All moving parts are fully covered

– Automatic stop or two-hand control within reach

– Use safe loading and unloading devices to increase productivity and reduce hazards caused by the machine

– Fully cover dangerous parts and areas of the machine

– Maintain the machine properly and regularly

Conclusion: Above is some useful information about safety principles in mechanical processing. Always follow the above principles to create a safe and effective working environment. Lostwaxcasting CLD is proud and committed to ensuring a working environment for its staff.
