INTRODUCTION TO HAZARD IDENTIFICATION, RISK ASSESSMENT AND DETERMINING CONTROL (HIRADC)

Hazard Identification, Risk Assessment and Determining Control (HIRADC) has become fundamental to the practice of planning, management and the operation of a business as a basic of risk management. 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.

With HIRADC, one will be able to identify hazard, analyse and assess its associated risk and then apply the suitable control measures.

This training 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.

OBJECTIVES

• To define what is hazard, risk and danger
• To explain the risk assessment process
• To describe the method of identifying hazard
• To use the risk assessment matrix
• To explain the hierarchy of control
• To develop the HIRADC activities
