Grinder machine Safety | What are the mechanical and Non-mechanical Hazards ? | Control Measures
Before get into it we will know what is Hazard ?
Hazard is something which has the potential to cause you harm.
Classification of Hazards :
- Physical (e.g Electricity)
- Chemical ( e.g Cement )
- Biological (e.g Hepatitis B Virus )
- Ergonomics (e.g Bricklaying )
- Psychological (e.g Work related stress )
Mechanical and Non-Mechanical Hazards
As per BS EN ISO 12100:2010 Safety of Machinery
The Hazards of machinery is divided into two parts :
- Mechanical hazards.
- Non-mechanical hazards.
- Mechanical Hazards :
Mechanical hazards are mainly from contact with or being caught by dangerous moving parts.
Such as :
⚠️ Cutting Hazard : contact is made with moving sharp-edged part such as a blade.
⚠️ Friction or Abrasion Hazard : when contact is made with fast moving surface which may be smooth.
⚠️ Ejection Hazard : when workers are hit by parts or objects flying out or off from machines.
⚠️ Entanglement Hazard : when clothing, hair or jewellery become caught in parts of a machine.
⚠️ Puncture Hazard : when sharp parts of machine or parts of material ejected from the machine and penetrate the body.
2 . Non-mechanical Hazards :
Non-mechanical hazards are mainly from the power source or things emitted by the machine.
Such as:
⚠️ Electricity Hazard : which may result in electric shock,burns , arcing or fire.
⚠️ Noise Hazard : which may cause hearing loss.
⚠️ Vibration Hazard : which may cause hand arm vibration syndrome.
⚠️ Dust Hazard : which is harmful if inhaled.
⚠️ Heat Hazard : as a result of accidental contact with hot blade.
Protective Measures :
For these Mechanical Hazards :
⚠️ Cutting Hazard
⚠️ Friction or Abrasion
⚠️ Ejection Hazard
⚠️ Entanglement Hazard
⚠️ Puncture Hazard
We will provide Fixed, enclosing guards around the abrasive wheel and appreciate PPE to protect our workers such as: eye protection (impact-resistant )
For these Non-mechanical Hazards :
⚠️ Electrical Hazard
⚠️ Noise Hazard
⚠️ Vibration Hazard
⚠️ Dust Hazard
⚠️Heat Hazard
We will provide appropriate PPE such as : earplugs or earmuffs , Dust Musk, grinding Gloves.
