In recent years, Hazard Identification, Risk Assessment and Risk Control (HIRARC) has become fundamental to the practice of planning, management and the operation of a business as a basic of risk management. The organizations that have carried out risk assessment at the work place have noted numerous changes in their working practice. Those who have already carried out risk assessment in their work, have reported positive changes in their working practice, they recognize substandard act and working condition as they develop and take necessary corrective action. Legislation requires that this process should be systematic and be recorded so that the results are reliable and the analysis complete. The risk assessment process should be continuous and should not be regarded as a one-off exercise.

In line with the Department approach of PREVENTIVE MEASURES as a way of enforcing the law on Occupational Safety and Health (OSH), it seems that HIRARC has became extremely important. With HIRARC, one will be able to identify hazard, analyze and assess its associated risk and then apply the suitable control measures. This Guideline is supposed to provide guidance on methodology of conducting HIRARC, it should be simple enough to be used by small and medium industries and should be versatile enough to be used by all in various economic sectors, either in the manufacturing sector, construction sectors or any other economic sectors.

The methodology of HIRARC as proposed in this Guidelines is intended for the assessment of physical hazards. Those who intend to assess health hazards in their workplaces, should make use of other risk assessment guidelines designed specifically for such purposes.

The Department would like to thank all the staff from Major Hazard Division for their effort and contribution in the preparation of this guideline.


The purpose of this guideline is to provide a systematic and objective approach to assessing hazards and their associated risks that will provide an objective measure of an identified hazard as well as provide a method to control the risk. It is one of the general duties as prescribed under the Occupational Safety and Health Act 1994 (Act 514) for the employer to provide a safe workplaces to their employees and other related person.
