9、nitarian, economic, and legal. in practice, all three are inter-related and probably reinforce one another. adoption of the following principles will provide a base for protecting company assets be they people, plant and/or equipment which is essential in a competitive market. 1accident prevention i

10、s an essential part of good management and of good workmanship.2management and workers must co-operate wholeheartedly in securing freedom from accidents.3top management must take the lead in organising safety in the works.4there must be a definite and known safety policy in each workplace.5the organ

11、isation and resources necessary to carry out the policy must exist.6the best available knowledge must be applied.accident definitionan accident is an unplanned, uncontrolled event that results in personal injury, property damage and/or some other loss, or could have resulted in personal injury, prop

12、erty damage and/or some other loss in slightly different circumstances.theory of accidentsaccident prevention is the technique of anticipating and controlling events so that accidents are avoided and the consequent damaging results do not occur. this technique covers a very wide field, dealing, as i

13、t does, with the attitudes and the unsafe conditions in the environment, thus ensuring the correct control systems are in operation.detailed research carried out in 1969 by f. bird extended the theory by bringing in property damage and likened the situation to an iceberg. the numbers quoted are aver

14、ages from a great variety of industries and will vary from industry to industry, but the principle applies universally. the position of the waterline on the "iceberg" represents the effective state of any accident prevention control system in any organisation because it denotes the dividin

15、g line between what is investigated and controlled and what is ignored.the essential fact to remember is that any "critical incident" could result in personal injury or property damage, or both; the seriousness of the result is purely a matter of chance. there are many examples to illustra

16、te this idea. for example:a maintenance job had been carried out years earlier and some brackets, although no longer of any use, had been left in place. an employee was walking past when one of the brackets fell.1it struck him on the head.result: a very serious, probably fatal injury.2the bracket bo

17、unced off a nearby shelf, caught the victim on the arm.result: minor injury.3the bracket knocked the material the employee was carrying from his/her grasp damaging it.result: property loss.4the bracket fell as the employee passed and dropped harmlessly to the floor.result: no visible injury or damag

18、e.this is why it is vital to control "critical incidents" which are the potential sources of personal injury and/or damage.identification and control of critical incidents leads to a safer work place, fewer incidents, fewer injuries, less damage to property and product.human contribution t

19、o accidentsaccording to bird and loftus a preventable accident is one of five factors in a sequence that results in injury, damage or some other loss. thus accidents are preventable , and so only occur as the culmination of a series of events or circumstances, which occur in a fixed, chronological o

20、rder. here a comparison can be made with a series of dominoes, placed on end such that if one falls it will cause the next to fall, and so on throughout the series. however, if the first domino were removed then the chain of events will be halted. the sequence of events are as follows:lack of manage

21、ment control from the organisation, permitting;basic causes (i.e. personal and job factors), leading to;immediate causes (unsafe acts and unsafe conditions), which are the direct cause of the accident, which results in a;contact with an energy or substance;loss (which may be categorised as injury, d

22、amage or some other loss).this sequence can be applied to all accidents, and is a basic tool for management control and accident investigation.the domino theoryunderlying, (root), causesdomino no. 1:organisationwherever people seek to make a living or achieve specified goals, organisations arise. th

23、e one characteristic that they all have in common is structure. they cannot function by allowing their members to do whatever they think needs to be done; they have to be organised.the formal structure takes place as duties are assigned, procedures adopted. so rules, and regulations are circulated a

24、nd the production processes are begun. in health and safety terms this is expressed in the setting of goals of commitment to safety and the demonstration to individuals that deviations are not acceptable.all the above is achieved by:1.controls?producing a safety policy. providing objectives and stan

25、dards for safety which are communicated to all.communication of these standards is achieved via information, instruction and training?carrying out risk assessments. to identify possible routes to human failure.producing rules and procedures to remove or minimise the risks identified by the risk asse

(audits, surveys, tours, inspections, safety contact, safety sampling and hazop studies).adequate and effective supervis

28、ve use of the lessons learned.domino no 2:basic causes:job factorssuccessful management of human factors involves the development of systems which have taken into account human capabilities and fallibilities. so careful design of the job is essential, and should ensure that no mis-match (either phys

29、ical or mental) occurs between the job requirements and the employees capabilities. otherwise, there will be the potential for human error.factors to be considered are:?likely human errors highlighted by risk assessments ?operator decision making - deciding on the optimum balance between human and a

30、utomatic contributions to safety actions. in other words, the level of automation required within the task.?ergonomics - this concerns the man/machine interface, and concerns how we make the job or machine fit the man. thus we consider layout of control panels, information displays, control devices

31、etc.?design and presentation of procedures and operating instructions. do we use operating manuals only, or do we use training sessions and leaflets as well? do we use words only, or words and pictures?organisational control of environmental factors: workspace, access for maintenance, and the effect

32、s of noise, lighting and the thermal environment etc.?provision of the correct/safe tools and equipment?scheduling of work patterns to control fatigue and stress - shift organisation, rest breaks, work variety, and arrangements for emergency situations.?effective communicationspersonal factorsthe or

33、ganisation and job factors will lead to a potential accident situation, and it will be the personal factors which now dictate how the person(s) will behave in that situation.these factors are as follows:stress stress is perhaps best understood in engineering terms. in a structure the various members

34、 are subject to loading, as in a bridge which is subject to different loadings at different times. for example, when traffic flows over the bridge it gives rise to internal and external stress.overloading structural members leads to overstress which can result in bending and/or fatigue, without nece

35、ssarily getting anywhere near the breaking strength. these well known conditions of stress and strain in engineering apply equally as well to people who live and work in stressful conditions. different personality types are better able to cope with high stress levels, and this is important when cons

36、idering appointing persons to high stress jobs egg fighter pilot, air traffic controller etc.stress due to organisational and job factors will be revealed in several ways, one of which is increased accident frequency.skillsskill concerns the performance of a task in a successful and rapid way. many

37、tasks fulfil this definition from typists to skilled craftsmen. it is recognised that there are individual differences in skill acquisition, and consequently, this must be a consideration in job design, especially when complicated skills are involved.personalitypersonality is the word used to descri

38、be the individuals perception of his total environment, including himself. so personality is directly linked to a persons behaviour as perceived by others egg honest, intelligent, loyal, serious etc. so where a supervisor has a personality that is considered by other workers to be weak, unintelligen

39、t, and disloyal this is important from a health and safety viewpoint because he will not be respected, and consequently any instructions that he gives are unlikely to be followed when he is not present.physiquethis concerns a physical rather than mental mis-match. certain jobs require strong physiqu

40、es e.g. scaffolder, labourer or soldier, whereas other jobs require less physical ability e.g. electrician, manager, receptionist. again if this is not considered by the organisation then this could result in a person that is not strong enough having an accident e.g. dropping a scaffolding tube from

41、 height.attitudeattitudes are sub-conscious filters that colour all information we receive. attitudes arise out of our beliefs, and are shaped by our education and experiences. this sub-conscious filter is important because it will colour all information, and so decide whether we perceive to like or

42、 dislike this information.motivationmotivation is important because it is a requirement within an unsafe individual in order to achieve a lasting alteration in his behaviour form unsafe to safe behaviour. this behaviour change is achieved by altering the persons underlying attitude(s), and this will

43、 only be possible with a suitably motivated individual.experienceour experiences as we grow older will shape and change our attitudes and thus, perceptions of ourselves and the world around us. the prime influences are:?economic?parents/friends?school?intelligenceconsiderations should include:1.task

44、 analysis for critical jobs will produce a job description and a specification for the person to match the job. this may include age, physique, skill qualifications, experience, aptitude, knowledge, intelligence, personality and will form the basis for recruitment and/or selection.2.training should

45、aim to, provide the skills for trainees to understand the workings of the plant and process so that they can work correctly under both routine and emergency conditions.3.monitoring of personal performance.4.fitness for workmedical standards, health surveillance, counselling/advice during stressful p

46、eriods.domino no 3:immediate causesunsafe acts88% of all accidents are caused by people - the unsafe act. this error could be on the part of anyone within the chain. therefore before we examine the unsafe act, we must examine the unsafe condition.we must decide to follow established safety rules and

47、 practices and also use as many of our senses as possible to observe the workplace to ensure it is safe."plan your action to remove the immediate causes""plan your action to remove the basic causes"“plan your action to remove the organisations lack of management control”the guide

54、 exclusively the breach of a contract or the breach of trust or other merely equitable obligation" (salmond).basically, a tort is a civil wrong, as distinct from a criminal wrong. one individual committing a wrong against another individual commits a tort.major torts are:- negligence- nuisance- defamation- conversion- trespass of goods- trespass to a person- trespass to landtort of negligencewhat is negligence?"negligence is the omission to do something which a reasonable man, guided upon those considera
