17、ontrol on construction and open sites. a list of organizations represented on this committee can be obtained on request to its secretary.Supersessiontogether with BS 5228-1:2008, this part of BS 5228 supersedes BS 5228-1:1997, BS 5228-2:1997, BS 5228-3:1997, BS 5228-4:1992 and BS 5228-5:1997, which

18、are withdrawn.Relationship with other publicationsBS 5228 is published in two parts:Part 1: Noise;Part 2: Vibration.BS 6472 gives detailed guidance on human response to vibration in buildings and BS 7385-1 covers the measurement and evaluation of structural vibration. BS 7385-2 contains guidance on

19、damage levels from groundborne vibration.an item dealing with the vibratory loading of structures, iSO/FdiS 10317, is being processed within iSO technical Committee iSO/tC 98/SC/2, Safety of structures. this is being monitored by BSi.Information about this documentthis British Standard refers to the

20、 need for the protection against noise and vibration of persons living and working in the vicinity of, and those working on, construction and open sites. it recommends procedures for noise and vibration control in respect of construction operations and aims to assist architects, contractors and site

21、 operatives, designers, developers, engineers, local authority environmental health officers and planners.noise and vibration can cause disturbance to processes and activities in neighbouring buildings, and in certain extreme circumstances vibration can cause or contribute to building damage.noise a

22、nd vibration can be the cause of serious disturbance and inconvenience to anyone exposed to it and in certain circumstances noise and vibration can be a hazard to health. attention is drawn to the legislation summarized in annex a.this is a full revision of this part of BS 5228, and introduces the f

23、ollowing principal changes:restructuring of the standard into two parts, one dealing with noise and one with vibration;updating of information relating to legislative requirements; updating of information relating to methods and equipment.

29、onstruction and open sites where work activities/operations generate significant vibration levels, including industry-specific guidance.the legislative background to vibration control is described and recommendations are given regarding procedures for the establishment of effective liaison between d

30、evelopers, site operators and local authorities.Guidance is provided concerning methods of measuring vibration and assessing its effects on the environment.2 Normative referencesthe following referenced documents are indispensable for the application of this document. For dated references, only the

For undated references, the latest edition of the referenced document (including any amendments) applies.BS 3015, Glossary of terms relating to mechanical vibration and shock3 Terms and definitionsFor the purposes of this part of BS 5228, the definitions given in BS 3015 and t

32、he following apply.3.1 air overpressureairborne pressure waves generated by blasting, produced over a range of frequencies including those which are audible and those which are below the lower end of the audible spectrum3.2 amplification factormotion measured at a given point (usually on the structu

33、re), divided by the motion measured at a reference point (usually at the base of the structure or on the foundation)3.3 peak particle velocity (PPV)instantaneous maximum velocity reached by a vibrating element as it oscillates about its rest position3.4 overburdenmaterial overlying the coal, or mine

36、olled Copy, (c) BSIBS 5228-2:20092 BSI 2008BritiSh StandardNOTE The VDV can be determined for continuous, intermittent, occasional and impulsive vibration. It takes account of the magnitude of the vibration events and the number and duration of those events, to quantify the total vibration exposure.

37、 The VDV is given by the fourth root of the integral of the fourth power of the acceleration after it has been frequencyweighted and is defined as:VdVb/d, day/night=atdtT40025().where:VDVb/d, day/nightis the vibration dose value (in ms1.75);a(t) is the frequencyweighted acceleration (in ms2), using

38、Wbor Wdas appropriate;T is the total period of the day or night, in seconds (s), during which vibration can occur.Further details of the VDV are given in BS 64721.4 Community relationsGood relations with people living and working in the vicinity of site operations are of paramount importance. Early

39、establishment and maintenance of these relations throughout the carrying out of site operations will go some way towards allaying peoples fears.it is suggested that good relations can be developed by keeping people informed of progress and by treating complaints fairly and expeditiously. the person,

40、 company or organization carrying out work on site should appoint a responsible person to liaise with the public. the formation of liaison committees with members of the public can be considered for longer term projects when relatively large numbers of people are involved.Vibration and air overpress

41、ure from blasting operations is a special case and can under some circumstances give rise to concern or even alarm to persons unaccustomed to it. the adoption of good blasting practices will reduce the inherent and associated impulsive noise: prior warning to members of the public, individually if n

42、ecessary, is important.5 Vibration and persons on site5.1 TrainingNOTE Attention is drawn to Regulation 8 of the Control of Vibration at Work Regulations 2005 2, which requires employers to provide information and training where the risk assessment indicates a potential risk to the health of employe

43、es as a result of exposure to vibration either handarm vibration (HAV) or whole body vibration (WBV) or where the employees are likely to be exposed to vibration levels above the relevant action levels. The Regulations require all employees to be advised of the following, as part of their training:t

44、he organizational and technical measures to be taken in order to a) comply with the requirements of Regulation 6;the exposure limit values and action values set out in Regulation 4;b) the significant findings of the risk assessment, including any c) measurements taken, with an explanation of those f

47、dentified as relating to a particular person.Operatives should be trained to employ appropriate techniques to keep site vibration to a minimum, and should be effectively supervised to ensure that best working practice in respect of vibration reduction is followed.a programme of monitoring should be

48、implemented to ensure that condition limits are not exceeded and that all the relevant recommendations are met.5.2 Protection from vibration exposureExposure to prolonged and regular work with high-vibration hand held tools can be a serious hazard to health. Workers using such equipment can suffer v

49、arious forms of adverse effects, collectively known as handarm vibration syndrome (haVS). the best known effect is vibration white finger (VWF) which is a prescribed industrial disease. Exposure to high levels of whole body vibration (WBV), e.g. for drivers of certain mobile plant in rough terrain conditions, can also be a serious hazard to health.at present, there is no effective personal protective equipment to alleviate the exposure to haV that is comparable to ear protectors in relatio
