Occupational safety is necessary for any industry or field, including mechanical manufacturing. Mechanical engineering is rising and plays an essential role in industrial development. However, it also contains potential elements and poses dangers to workers. Therefore, to ensure labour safety in the mechanical workshop, we first need to understand the concept of safety and safety measures to proactively prevent and contribute to ensuring the lives of people and property. Because of its importance, 83MEC wants to share helpful information about safety in mechanical production with readers.

I. What is the safety concept in mechanical processing?

  • Occupational safety in the mechanical industry is the application of activities and measures to ensure the safety of employees working in workshops during production, processing or construction.
  • The danger in the mechanical field is sources/places of hazardous and harmful factors that can cause injury in production due to the shape, size, and movement of production facilities and other factors processing details harmful to workers such as: cutting, milling, grinding, rolling, stamping, scissors,… It is also the source of problems with many different levels of severity.

II. Why care about safety in mechanical processing?

– Safety must be a priority in mechanical production to minimize injuries and damage to employees and prevent loss of life and property.

– Many objective and subjective causes lead to unsafety in mechanical processing, and there are always potential dangers to us, so workers must constantly monitor the working conditions on occupational safety from the design, manufacture, and use of machinery and equipment,… to protect themselves and everyone else.

III. Common accidents in mechanical machining

  • Accidents are something nobody desires. However, if employees are not cautious, potential dangers will always threaten and injure them. Typical catastrophes in the mechanical processing industry:

+ Materials (embryos) splash into eyes, skin,…;

+ Being rolled, clamped, cut,…;

+ Clothes and hair get caught in the machine while operating

+ Electric shock

+ Burns

+ Stumbled 

IV.  Causes of accidents in mechanical machining 

4.1 General causes 

– Protective equipment and shielding are not enough to ensure safety.

– The clothes do not comply with regulations, leading to tripping on operating machinery and equipment.

– During the working process, the employee lacks protective equipment or the protective equipment is damaged

– Failure to regularly check machinery and equipment (control buttons, switches,…), leading to damage without knowing it, accidentally causing occupational accidents while using machinery and equipment.

– The working environment lacks light, obstructs the ability to observe the surroundings, and the noise exceeds acceptable standards.

– Working place lacks space, cramped, unscientific arrangement, unfavorable movement is one of the causes of unsafety.

– Lack of knowledge about mechanical processing safety and subjectivity leads to violations of machinery operating procedures, standards and state regulations, etc.

– The technological criteria and operating procedures have yet to be designed following the safety standards in the industries and fields in which the machines operate.

4.2 Cause-Specific 

a. Loss of safety in cutting

– Parts of the body (hair, hands, feet,…) or clothing are not correctly sized or neat, leading to the risk of being caught directly into the machine while operating.

– The material is not durable, when put into operation, it is easy to cause the phenomenon of material splashing on people.

– The drill bit is not securely installed and slips, causing it to fall out, the clamping table is not tight, which can drop the workpiece,… causing an accident.

b. Loss of safety in cold working

– Workers are not well-versed in professional knowledge, improper processing movements and postures.

– Hand tools (such as hacksaws, files, chisels,…) are easily cause an impact on people.

– Because cold processing machinery (small presses, bench drills, grinding wheels,…) are designed quite simply, the structure is not sustainable, lacks synchronization, and lacks safety.

– Improper standing while cooling generally leads to scoliosis.

c. Loss of safety metal welding-cutting

– When welding electricity, electric shock accidents due to open electricity are the most dangerous for human life

– Liquid metal may splash around, causing burns.

– Arc welding has intense radiation and high heat, easily causing skin burns and eye pain for workers.

– Arc fire can easily explode surrounding objects, so avoid placing them near flammable and explosive objects.

– Welders working in dangerous environments: toxic gases, waste dust such as CO2, F2, manganese dust, zinc oxide dust, … harmful to breathing and workers’ health when welding

– When welding steam, using compressed air containers, grease stains, flammable substances on the wires, and gas valves, … can easily cause fire, explosion or fire.

– Processing in dangerous terrains such as overhead, inside pipes, in earthen cages.

d. Loss of safety in pressure machining 

– The accident occurred due to rolling, stamping, forging, … in a hot state, causing burns to workers.

– When machining is complete, the forging is still hot but accidentally collides with it, causing burns

– Not being careful while using forging tools (hammer, pliers)

– Due to carelessness in the process of using hand tools (pliers, hammers, scissors, …), the hammer handle is not tight when it is thrown out when the hammer handle, pliers take the forging out of the furnace, it is unlikely that the hot object will drop. .

– The workpiece is thrown out due to unstable workpiece fixing details or incorrect clamping position.

e. Loss of safety in heat treatment

– Impact on the workpiece at high temperature.

– Heat treatment environment is easily toxic to humans. 

f. Loss of safety in electroplating

– Electrolyte solution causes skin burns and skin damage when accidentally exposed

– Toxic vapors pollute the environment.

– When operating electrolytic equipment with large currents, attention should be paid to electrical safety. 

V. What does 83MEC do to ensure safety in mechanical machining? 

5.1 General principles

– Fully equipped with professional knowledge and skills in occupational safety and health following current regulations of the Nation in all stages from design to manufacture, installation, operation and management of machinery and equipment.

– Identify details, objectively assess possible hazards and unsafe sources.

– Fully implement safety protection measures for workers. 

– Design and arrange the premises of the workshop scientifically, ensuring safety conditions such as:

+ The location to install the machine is suitable;

+ The factory layout is neat, and specialized machines are installed in each zone, which is convenient for moving;

+ Machines and equipment for mechanical processing in the factory are installed according to the correct technique, ensuring safety according to safety regulations;

5.2 Safety rules when using machines and equipment

– Only arbitrarily start and operate machinery after fully understanding it (except for the person in charge).

– Regularly check, maintain and repair equipment and machinery in the factory to promptly detect hazards that are dangerous to workers. At the same time, quickly report damage and abnormalities of machinery and equipment to the manager for a timely response.

– Before starting work, it is necessary to check machinery and equipment for safety and adjust the standing position to ensure safety.

– When there is a sudden power failure, it is necessary to turn off the power switch to ensure that the machinery does not operate unexpectedly when there is electricity, causing workers to unintentionally fail to respond in time, affecting the body, and even causing injury.

– When there is no person in charge of control, it is necessary to turn off the entire machine, do not arbitrarily use it

– When you want to adjust the machine, the worker must turn off all the power and ensure the machine stops working completely to avoid electrical accidents.

– Wear neat, well-fitted clothing when operating the machine to avoid being caught directly in the operating machine.

– For broken machines, warning signs should be posted to notify all workers.
