Investigation at site of collapsed factory structure The five essential elements to good management of OSH on construction sites are derived from the lessons learnt from previous accidents and good management practices of construction projects. Managing site safety should be a shared responsibility among all employers in the project’s supply chain, especially the client, the designer and the contractor. Every employer in each phase of a construction project — from conception, design, procurement, construction, start up, future maintenance to the use of the building, including demolition — is recommended to take responsibility for every risk he creates. The proceeding paragraphs briefly explain these five important elements. 1. Principles of risk management and prevention These set out the principles which all employers should use in their approach to identify the practical measures they should take to control the risks in a particular project. A risk management process is a systematic way of making a workplace as safe as possible and it should also be used as part of the design process. It involves hazard identification, risk assessment, risk control and the review of control measures. Part of the risk assessment is to determine who will be affected by the work activity. Person at risk should also include workers who are not directly involved with the work activity, but workers that possibly move around the site. General guidance on the risk management process is available in the Guidelines for Hazard Identification, Risk Assessment and Risk Control (HIRARC) 2008 by the Department of Occupational Safety and Health (DOSH) and industry specific guidance can be sought from the Handbook on Hazard Identification, Risk Assessment and Risk Control (HIRARC) 2015 by the Master Builders Association Malaysia (MBAM). It is noteworthy that OSH risk management should be an active process, and not be treated merely superficially as a paper exercise to comply with the law. The principles of prevention can be summarised as: (a) avoid risks where possible; (b) evaluate those risks that cannot be avoided; and (c) put in place proportionate measures that control them at source. 27
