22. 香港職業安全衛生協會 Hong Kong Occupational Safety and Health Association Risk Management • determine priorities • allocate resources

23. 香港職業安全衛生協會 Hong Kong Occupational Safety and Health Association 風險 ≠ 危害 Risk ≠ Hazard 風險評估 ≠ 危害識別 Risk Assessment ≠ Job Hazard Analysis

24. 香港職業安全衛生協會 Hong Kong Occupational Safety and Health Association British Standard BS 8800:2004 Occupational Health and Safety Management Systems Hazard source or situation with a potential for harm in terms of death, ill health or injury, or a combination of these Hazard Identification process of recognizing that a hazard exists and defining its characteristics

25. 香港職業安全衛生協會 Hong Kong Occupational Safety and Health Association Risk combination of the likelihood and consequence(s) of a specified hazardous event Risk Assessment process of identifying hazards and evaluating the risks to health and safety arising from these hazards taking account of the existing risk control (or, in the case of a new activity, the proposed risk controls) Risk Control selection and application of suitable measures to reduce risk

26. 香港職業安全衛生協會 Hong Kong Occupational Safety and Health Association Unacceptable Risk risk that cannot be accepted whatever the level of benefits gained from the activity giving rise to the risk Tolerable Risk risk at a level that can be accepted provided risk controls are implemented to reduce risk as low as is reasonably practicable i.e. reduced to the point where it can be shown that the costs (in terms of time, money and/or effort) of further risk reduction would be disproportionate to the further benefits

27. 香港職業安全衛生協會 Hong Kong Occupational Safety and Health Association Aacceptable Risk risk that is regarded as insignificant either as it stands, or as a result of risk control Each organization should define, according to its own circumstances, the boundaries between levels of risk. The level of risk should be determined as an unacceptable risk, tolerable risk or an acceptable risk.

28. 香港職業安全衛生協會 Hong Kong Occupational Safety and Health Association 風險評估(risk assessment) Risk assessment is a process comprising • hazard identification 危害識別 • risk assessment 風險評估 • risk control 風險控制

29. 香港職業安全衛生協會 Hong Kong Occupational Safety and Health Association Hazards Physical Hazards Chemical Hazards Biological Hazards Psychological Hazards

30. 香港職業安全衛生協會 Hong Kong Occupational Safety and Health Association Physical Hazards • slippery or uneven ground leading to slips/falls on a level • work at heights, leading to falls (linked to factors such as the distance of the fall) • falls from height of objects such as tools or materials, leading to impacts on passers by • inadequate space to work, such as low headroom, leading to head impacts • poor ergonomics (e.g. bad posture or repetitive work), leading to acute or chronic health effects

31. 香港職業安全衛生協會 Hong Kong Occupational Safety and Health Association Physical Hazards • manual lifting/handling of materials, etc., with the potential for back, hand and foot injuries (linked to factors such as the characteristics of the load) • trappings, entanglement, burns and other hazards arising from equipment • transport hazards, either on the road or on premises/sites, while travelling or as a pedestrian (linked to the speed and external features of vehicles and the road environment • fire and explosion (linked to the amount and nature of flammable material)

32. 香港職業安全衛生協會 Hong Kong Occupational Safety and Health Association Physical Hazards • harmful energy sources such as electricity, radiation, noise or vibration (linked to the amount of energy involved) • stored energy, which can be released quickly and cause physical harm to the body (linked to the amount of energy) • frequently repeated tasks, which can lead to upper limb disorders (linked to the duration of the tasks) • unsuitable thermal environment, which can lead to hypothermia or heat stress

33. 香港職業安全衛生協會 Hong Kong Occupational Safety and Health Association Physical Hazards • Violence to staff, leading to physical harm (linked to the nature of the perpetrators) • ionising radiation (from x- or gamma-ray machines or radioactive substances) • Non-ionising (e.g. light, magnetic, radio-waves)

34. 香港職業安全衛生協會 Hong Kong Occupational Safety and Health Association Chemical Hazards • substances hazardous to health or safety due to inhalation (such as carbon monoxide (CO) the hazard would be liked to the amount of CO) • contact with, or being absorbed through, the body (such as acids the hazard would be linked to the strength and amount of the acid) • ingestion (i.e. entering the body via the mouth), such as lead paint • stored materials that degrade over time (such as oxidizers) • lack of oxygen

35. 香港職業安全衛生協會 Hong Kong Occupational Safety and Health Association Biological Hazards • Biological agents, such as bacteria or viruses that might be: i) inhaled ii) transmitted via contact with bodily fluids (including needle-stick injuries). The hazard would be linked to the nature of the pathogen iii) ingested (e.g. via contaminated food products)

36. 香港職業安全衛生協會 Hong Kong Occupational Safety and Health Association Psychological Hazards • excessive workload, lack of communication or control, workplace physical environment, leading to stress (linked to the magnitude and duration of stressors) • physical violence, bullying or intimidation within the workplace, leading to stress • involvement in a major incident, leading to post traumatic stress. The hazard would depend on the nature of the incident

37. 香港職業安全衛生協會 Hong Kong Occupational Safety and Health Association Classify work activities Identify hazards Identify risk control Estimate risk The process of risk assessment and control Determine the tolerability of the risk Review Prepare risk control action plan to improve risk controls as necessary Review adequate of action plan – confirm whether risks are now acceptable or tolerable Ensure risk assessment and controls are effective and up-to-date

38. 香港職業安全衛生協會 Hong Kong Occupational Safety and Health Association 風險評估(risk assessment) 人、機械、產品、環境 鑑別危害，決定可接受及剩餘風險，風險評估，減低風險 識別危害，決定風險嚴重性及可能性，決定風險水平，決定控制及安全措施 可接受、減低、避免、風險轉移 控制及安全措施 風險記錄 Risk Register

39. 香港職業安全衛生協會 Hong Kong Occupational Safety and Health Association Hierarchy of Risk Control • eliminate hazards, e.g. use of safe substance instead of a dangerous one • reduce the risk at source, by use of low voltage electrical appliances, introduce machinery guards • reduce risk via procedures and safe systems of work • adopt personal protective equipment (PPE)
