Report to your supervisor if further analysis is needed,Five X Five Technique,2021/4/5,环境健康安全风险评估,25,Documented informal (individual) and structured (team) inspections are conducted periodically to identify deficiencies,Workplace Audits or Inspections,2021/4/5,环境健康安全风险评估,26,Target areas include:,Workplace Audits or Inspections,Cranes Assessing the potential severity of the hazards; Determining the likelihood of occurrence and Assessing the risk level based on the severity and likelihood. Risk evaluation is the process of estimating the risk levels for the hazards and their acceptability. This is used as a basis for prioritizing actions to control these hazards and minimize safety and health risks.,Simple Risk Assessment Tool,2021/4/5,环境健康安全风险评估,41,Existing risk control The presence of existing control measures should first be identified for individual activity for each process. By considering the effectiveness of the existing controls and the consequences of their failure, the risk of the activity can be assessed. Examples of risk control measures include engineering controls, safe work procedures and personal protective equipment.,Simple Risk Assessment Tool,2021/4/5,环境健康安全风险评估,42,Simple Risk Assessment Tool,2021/4/5,环境健康安全风险评估,43,Simple Risk Assessment Tool,2021/4/5,环境健康安全风险评估,44,Simple Risk Assessment Tool,2021/4/5,环境健康安全风险评估,45,Step 3 - RISK Control,Simple Risk Assessment Tool,2021/4/5,环境健康安全风险评估,46,Simple Risk Assessment Tool,环境健康安全风险评估,47,Elimination or substitution,Engineering controls,Warnings,Training and procedures,Protective Equipment,Examples,Risk Assessment - Risk Control Hierarchy,2021/4/5,环境健康安全风险评估,48,2021/4/5,环境健康安全风险评估,49,The control of hazards and reduction of risks can be accomplished by following the Hierarchy of Control measures below. These control measures are not usually mutually exclusive e.g. engineering controls can be implemented together with administrative controls like training and safe work procedures.,a) Elimination Elimination of hazards refers to the total removal of the hazards and hence effectively making all the identified possible accidents and ill health impossible. This is a permanent solution and should be attempted in the first instance. If the hazard is removed, all the other management controls, such as workplace monitoring and surveillance, training, safety auditing, and record keeping will no longer be required. Example Laser marking of semiconductors eliminates the use of solvent for ink marking. Laser cutting eliminates noise hazard from powered saws.,2021/4/5,环境健康安全风险评估,50,b) Substitution This involves replacing the hazard by one that presents a lower risk. Example. Asbestos can be substituted with non-asbestos materials. A water-based paint can be used instead of a solvent-based paint.,c) Engineering controls Engineering controls are physical means that limit the hazard. These include structural changes to the work environment or work processes, erecting a barrier to interrupt the transmission path between the worker and the hazard. Example Isolation or containment of hazards, application of machine guards and manual handling devices.,2021/4/5,环境健康安全风险评估,51,d) Administrative controls These reduce or eliminate exposure to a hazard by adherence to procedures or instructions. Documentation should emphasize all the steps to be taken and the controls to be used in carrying out the activity safely. Examples Implementation of permit-to-work systems and scheduling of incompatible works; OSH training. e) Personal protective equipment This should be used only as a last resort, after all other control measures have been considered, or as a short term contingency during maintenance / repair or as an additional protective measure. The success of this control is dependent on the protective equipment being chosen correctly, as well as fitted correctly and worn at all times when required by employees.,2021/4/5,环境健康安全风险评估,52,Residual Risks The risk assessment team should ensure that the risk assessment is conducted properly, and that any residual risks are acceptable and manageable. Residual risks are the remaining risks for which the planned risk controls are not able to effectively remove or control. The risk assessment team should also highlight the residual risks of each of the controls. For example, if the risk control involves the use of fall arrest harness and lanyards (a type of personal protective equipment), then one of the residual risks is that the workers may not hook up the lanyards to protect themselves. In this case, the risk assessment team may highlight training (administrative control) as a further measure to ensure that residual risk is further minimized. Once all the risk controls are selected and their residual risks highlighted, the risk assessment team needs to identify the action officers and follow-up dates. In this way, the specific action officers to implement the controls can be clearly identified, and the follow-up dates will help to ensure timeliness in implementation.,Simple Risk Assessment Tool,2021/4/5,环境健康安全风险评估,53,IMPLEMENTATION AND REVIEW,The results of risk assessment must be approved and endorsed by the top management. The employer should as far as is practicable, implement the recommended risk control measures as soon as possible. An action plan should be prepared to implement the measures. The plan should include a time line of implementation and responsibilities of persons implementing the workplace safety and health measures. The plan should be monitored regularly until all the measures are implemented. Regular review of the risk assessment plan is critical. While employers are required to review their plans yearly, a review should take place whenever: Whenever new information on safety and health risks surfaces; There are changes to the area of work and / or After any accident or serious incident. The risk assessment team should undertake the same three steps (hazard identification, risk evaluation and risk control) when conducting a risk assessment review.,Simple Risk Assessment Tool,2021/4/5,环境健康安全风险评估,54,Spray Painting/ Workshop,- Moving metal drums to spray booth - Preparing and mixing paint - Carrying out spray painting,Paper Slitting/ Cutting Department,2,- Loading the machine with paper roll - Operating the machine - Unloading slit papers - Repair and maintenance of the machine,Simple Risk Assessment Tool,2021/4/5,环境健康安全风险评估,55,Simple Risk Assessment Tool,2021/4/5,环境健康安全风险评估,56,Simple Risk Assessment Tool,2021/4/5,环境健康安全风险评估,57,Simple Risk Assessment Tool,2021/4/5,环境健康安全风险评估,58,Simple Risk Assessment Tool,2021/4/5,环境健康安全风险评估,59,Risk Assessment Focus,Incident Investigation Focus,Risk Assessment vs. Incident Investigation Focus,2021/4/5,环境健康安全风险评估,60,Ten Steps to Effective Risk Assessment,Make sure the process is practical and realistic Involve as many people as possible Use a systematic approach Look at the big picture Start by identifying the hazard,2021/4/5,环境健康安全风险评估,61,Ten Steps to Effective Risk Assessment,6.Assess the risks from those hazards 7.
