28、 organization, employer or employee who has a responsibility for an aspect of health, safety and welfare NOTE In organizations and companies this is particularly those who have the authority and capacity to be active in preventing or controlling risks.

NOTE 2 This definition is different to that given in ISO/IEC Guide 73. 4

37、 Principles of risk assessment and risk management 4.1 General consideration of risk assessment within management systems Every organization should have a set of identified goals for its operations. Strategic planning and decisions determine broadly how these goals are to be attained taking into acc

38、ount external constraints and the concerns of stakeholders. Tactical planning and decision making concern choices of approach and methods within the strategic framework. Operational decisions take account of the precise conditions existing at the time. Within the operations of an organization, risk

39、management (see 3.9) is a core process as it aids the attainment of goals and reduces costly surprises. It should be integrated into all levels of planning and decision taking. This part of BS 7971 concentrates on risks to health and safety of people and the management of these risks. Further discus

40、sion and details of the concept of risk management within the operations of an organization are given in BS 6079-3:2000 and BS 8444-3:1996. The management of occupational health and safety at work is an integral element within the overall management of the operations and projects of an organization.

41、 Therefore it should be included within all planning and decision taking processes; it is not separate from them. Details of how this can be done are given in BS 8800:1996. Employers have a statutory duty to comply with the Management of Health and Safety at Work Regulations 1999 1. Advice on how to

42、 comply with these regulations is given in the Health and Safety Executive (HSE) Approved Code of Practice Management of Health and Safety at Work 3. The advice is specific about processes but inevitably general regarding their application. This part of BS 7971 gives guidance on the application of t

43、his advice to the provision of protective clothing and equipment for use in violent situations.BS 7971-2:2003 BSI 11 April 2003 3 Within risk management in occupational health and safety management, risk assessment (see 3.8) plays a key role. The Management of Health and Safety at Work Regulations 1

44、999 1, Regulation 3, states the following: “Risk assessment 3. - (1) Every employer shall make a suitable and sufficient assessment of - (a) the risks to the health and safety of his employees to which they are exposed whilst they are at work; and (b) the risks to the health and safety of persons no

45、t in his employment arising out of or in connection with the conduct by him of his undertaking,” Risk assessment is a major tool in managing health and safety at work and should be applied to all aspects of managing violent situations. It encompasses risk analysis and risk evaluation. Guidance on ri

46、sk assessment is given in Annex A. This is directed particularly at risk assessment related to the selection and use of clothing and equipment specified in the other parts of BS 7971. However all decisions taken concerning the management of violent situations effect the decisions that have to be tak

47、en regarding the selection and use of clothing and equipment, and therefore should be examined and if necessary reviewed with a view to implementing changes where the risk assessment shows these are appropriate. A fundamental principle underpinning the Health and Safety at Work Etc. Act 1974 4, is t

48、hat those who create risks (see 3.7) from work activity are responsible for protecting workers and the public from the consequences. The broad general duties are explicitly placed on those who are in the best position to do something about preventing or controlling the risks. The nature of risk is t

49、hat it always contains two elements; the frequency or probability with which a hazardous event occurs and the severity of the consequences of such a hazardous event. A hazard (see 3.3) exists when an inherent property of a system could cause harm to an individual or property. In a violent situation the hazards are mainly created by the opponent (see 3.4) who by intent, or inadvertently due to a medical condition, creates t
