7、formationThis British Standard was published by BSI and came into effect on 31 July 2006. It was prepared by Subcommittee PH/3/3, Protective clothing from chemicals and radioactive contamination, under the authority of Technical Committee PH/3, Protective clothing. A list of organizations represente

8、d on this committee can be obtained on request to its secretary. Relationship with other publicationsThis British Standard is intended to be used in conjunction with BS 8468 (all parts), which gives requirements for respiratory protective equipment for use with ensembles such as those covered by thi

9、s standard.NOTE All or some of the parts of BS 8468 might be appropriate depending upon the requirements identified. BS 8468 will be published in seven parts: Part 1: Positive pressure, self-contained breathing apparatus Specification; Part 2: Negative pressure air purifying devices with full face m

10、ask Specification; Part 3: Escape hoods Specification; Part 4: Powered air-purifying respirators Specification; Part 5: Dual-mode apparatus Specification; Part 6: Positive-pressure compressed airline equipment Specification; Part 7: Closed-circuit breathing apparatus Specification.Information about

11、this documentIncreased threat from chemical, biological, radiological and nuclear (CBRN) agents has led to a need for suitable personal protective equipment (PPE). The lack of coverage of combined CBRN protection in existing British Standards on PPE has recently been identified. This standard has be

12、en prepared to give requirements for such PPE.Presentational conventionsThe provisions of this standard are presented in roman (i.e. upright) type. Its requirements are expressed in sentences in which the principal auxiliary verb is “shall”.Commentary, explanation and general informative material is

13、 presented in smaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.Compliance with a British Standard cannot conf

14、er immunity from legal obligations. BSI 2006 1BS 8467:2006IntroductionThis Standard has been prepared using, wherever possible, British and European standards as a base in order to more easily facilitate both the availability of testing and the CE marking process.This standard has been prepared bear

15、ing in mind existing individual items of PPE that when used together could form an ensemble.The ensembles covered by this standard are intended for immediate or nearly immediate response to a CBRN challenge whether this is as a result of accidental release or through terrorist activity. Such ensembl

16、es are not necessarily intended for use some time after a release has occurred such as in the case of building decontamination (as opposed to casualty decontamination). In such cases, BS 7184 might provide suitable guidance.NOTE The term CBRN is used in Home Office publications (e.g. The release of

17、CBRN substances or material 1) to describe a range of incidents that can occur as a result of a release of chemical, biological or radiological material.The categories of ensemble have been selected based upon the anticipated activities expected to be undertaken by personnel, and the associated phys

18、iological demands, together with the knowledge of ensembles currently available.1 ScopeThis British Standard specifies requirements for personal protective ensembles intended to be used during rescue, evacuation, escape, hazard containment, decontamination and similar associated activities by first

19、responders, fire, ambulance, police and associated civilian agencies and workers, for protection during chemical, biological, radiological and nuclear (CBRN) events. This standard covers a variety of ensembles intended to provide a range of levels of protection against chemical warfare agents, toxic

20、 industrial chemicals and materials, biological agents and contamination by radioactive particles. It is assumed that an equivalent amount of protection from radioactive particles will be provided as a result of the protection that is provided from particulate chemical agents.This standard does not

21、cover ensembles intended to provide protection from irradiation by ionizing radiation, i.e. beta and gamma radiation, and for which no currently available chemical protective clothing will necessarily offer significant protection. Nor does it cover blast or heat protection from a nuclear device. Thi

22、s standard is not necessarily appropriate for responders to releases from establishments where the nature of the hazardous material is known in advance and where the establishment has emergency plans that include provision of appropriate PPE.NOTE 1 Ensembles conforming to this standard might be suit

23、able for use in situations other than those involving the specific CBRN agents identified in the standard. Information supplied by the ensemble suppliers or individual component manufacturers will indicate such additional possible performance applications.BS 8467:20062 BSI 2006Some typical anticipat

24、ed environments and activities for which the various categories of ensemble could be used are also provided.This standard identifies categories of ensembles and their associated performance requirements and test methods in order that ensembles can be categorized. This includes both material specific

25、 requirements and full ensemble testing.The performance requirements in this standard might be achieved by ensembles regardless of whether they are of the reusable, limited life or disposable type.NOTE 2 Ancillary items that might be used with an ensemble (e.g. lifejackets, guns, ballistic vests, hy

26、dration systems) and/or their compatibility with the ensembles are not covered by the standard.This standard also considers compatibility and interface with respiratory protective devices, and application and marking of the equipment, including user information.Ensembles that conform to this standar

27、d are designed to be used with respiratory protective devices. This standard does not identify the specific performance requirements for such respiratory protective devices. However some additional requirements for the respiratory element when it is used as part of the ensemble are included in this

28、standard, for example full system testing.BS 8468 (all parts), will provide the performance requirements specific to the respiratory devices for protection against CBRN agents to be used in conjunction with the ensembles identified in this standard.Annex A provides advice and guidance on selection,

29、use, care and maintenance and Annex B provides an informative check list of performance requirements in relation to the Essential Health and Safety Requirements of the PPE Directive 2 in order to assist manufacturers and Notified Bodies in preparing certification against the PPE Directive. Annex C g

30、ives requirements for full ensemble system testing for CBRN agents. Annex D gives the test methodology for material swatch testing for CBRN agents. Annex E gives a test methodology for testing permeation resistance to challenge chemicals in droplet form.2 Normative referencesThe following referenced
