Identification of Risk Source

Mechanical Risk Source
Machines have various risk sources. First, it is necessary to identify these risk sources. Risk sources can be largely classified into the following categories. This section focuses on mechanical risk source which is one of the common risk sources.
Crushing
  
Shearing
Risk of a crushing injury Risk of a shearing injury
Cutting
  
Rolling in
Risk of a cutting injury Risk of a rolling injury
Drawing
  
Thrusting
Risk of a drawing injury Risk of a thrusting injury
* Other risk sources are such as biting, shock, rubbing, etc.

Electrical Risk Source
Contact with live parts, insufficient insulation resistance, static electricity, etc.
 

Thermal Risk Source
Fire, explosion, contact with live parts, insufficient insulation resistance, static electricity, etc.
   

Risk Source Caused by Noise
Hearing loss, ear ringing, etc.
 

Risk Source Caused by Vibration
Disorder of the body parts, etc. caused by mechanical vibration.
   

Risk Source Caused by Radiation
Ultraviolet rays, X rays, laser beams, low or high frequency, etc.
 

Risk Source Caused by Material, Substance
Hazardous substance, combustible material, etc.
   

Risk Source Caused by Negligence of Ergonomics
Forcing unnatural posture, poor visibility of indicators, etc.
