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

 

Application
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.

 

Methodology

• 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
