Simple Risk Assessment And Control (SiRAC)

ATTENTION: : This assessment and control system is still in the process of discussion; therefore all information contained here is subject to change from time to time.

What is SiRAC?

  • It stands for Simple Risk Assessment and Control.
  • A system to carry out a simple assessment based on a process of grouping workplace risks into control bands based on combination of hazard and exposure information.
  • Emphasis is on risk control
  • Based on UK’s COSHH Essentials


May be conducted if all chemicals hazardous to health used in a particular work unit meet these criteria:

  • Chemicals listed in chemical register; and
  • Any chemicals not classified as carcinogenicity category 1; mutagenicity category 1 or 2; or respiratory sensitization category 1.


Does not apply to the following types of chemicals:-

  • classified as CATEGORY 1 Carcinogenicity, Mutagenicity or Respiratory Sensitization;
  • process generated dusts and fumes
  • organic dust
  • gases


Who Can Conduct?
A person should have knowledge on :

  • how to interpret Safety Data Sheets (SDS);
  • work processes and tasks;
  • basic principle of Hazard Identification Risk Assessment and Risk Control (HIRARC); and
  • basic requirement of the Occupational Safety and Health Act 1994 (OSHA), USECHH and relevant guidelines.



  • Risk Equation:
    - Risk = Hazard X Exposure
  • Hazard is described in terms of hazard groupings (hazard statement/code)
  • Exposure is represented by these parameters:
    - Scale of use
    Ability to become airborne
    Frequency & duration of exposure
