Note: For processes and activities where JSA is not suitable, other methods such as Failure Modes Effects Analysis (FMEA)/Fault Tree Analysis (FTA)/Event Tree analysis shall be selected. 4.3
Risk Assessment Criteria
4.3.1
Risk assessment shall be carried out in compliance with Workplace Safety & Health (Risk Management) Regulation 2006 using the guidelines provided in Attachment III using the following criteria: (a) The impact rating of the consequences of occurrence/exposure to the hazard; (b) The frequency rating of occurrence/exposure; (c) Based on the application of the impact rating and frequency rating, the risk level associated with the tasks shall be established. If the risk level is high then the associated work activity is classified as a high risk work activity and; (d) Review and record it as described in SIAEC Risk Assessment Part 1: Assessment with Existing Control Measures form. (See Appendix)
4.3.2
All reasonably practicable steps shall be taken to eliminate any foreseeable risk identified during the hazard identification and risk assessment exercise.
4.4
Additional Control Measures
4.4.1
Based on the results of risk assessment, additional control measures shall be implemented as per the guidance in attachment III If risk reduction is required, SIAEC Risk Assessment Part 2: Assessment of Risk Reduction Action form should be completed. (See Appendix)
4.4.2
The following guidelines shall be followed where feasible:
.1
Elimination
-
It refers to the total removal of the hazards and hence effectively making all identified possible accidents and ill health impossible. This is permanent solution and should be attempted in the first instance.
.2
Substitution
-
Where hazardous materials have been identified as a hazard then the preferred option is to replace the material with a less hazardous one or presents lower risk.
.3
Engineering
-
The removal of the potential hazards by reengineering the job or providing physical means that limits the hazard. This, for example may involve such action as redesigning pipe-work/ equipment or configuring a crane
.4
Administrative Control
-
The application of administrative control to hazards may include such actions as limiting the time of exposure, rotating of personnel, restricting unauthorised entry, etc
