7.4. Establish controls

Determine the required control measures for each identified hazard. The control measures must be applied for each hazard individually or in combination and must be effective in reducing the resultant risk for each hazard to ALARA levels.

It should be noted that:

  • all hazards and resultant risk must have at least one control measure.
  • the current controls in place must be reviewed to ensure that the controls are appropriate and effective.
  • additional controls identified in the JSA must be available and in place while the job is being performed.
  • all controls must be realistic and effective in controlling the hazards and resultant risks.
  • each control may have a person identified as responsible for implementing it communicating the hazards and controls to the personnel performing the job is essential.

It is of little value to identify hazards and devise controls if the controls are ineffective or not implemented. The following control need to be keep in JSA:

i. Engineering controls eliminate exposure to the hazard by:

  • Isolating the employee from the hazard
  • Improving (redesign) work area layout
  • Substituting less hazardous product
  • Modifying equipment

ii. Administrative controls reduce employee exposure to a hazard by:

  • Reducing the frequency of performing the hazardous task
  • Rotating employees to reduce exposure time
  • Training employees to recognize hazards and employ safety practices.

iii. Work practice controls include:

  • Workplace rules
  • Safe & healthful work practices
  • Personal hygiene
  • Housekeeping and maintenance
  • Procedures for specific operations

iv. Use of PPEs (Personal Protective Equipments)

  • PPE reduce employee exposure to hazards when engineering and administrative controls are not feasible or effective.
  • PPE alone should not be relied on to protect against hazards; other uses include guards, engineering controls, and sound manufacturing practices.

v. Training: Another way is to prevent exposure to a hazard is training

  • The nature of hazards which may occur;
  • How to recognize hazardous conditions;
  • Procedures which will insure work is done safely in the vicinity of a hazard;
  • Personal protective equipment which is required, and how to use it effectively;
  • Procedures to follow if there is an emergency.

Efficient supervision:Efficient supervision is required, inefficient supervision has lot of safety and risk limitations as briefed below:
