21、genital protectors are items of protective clothing which are generally, but not exclusively, worn by serving police officers and prison officers whilst they are engaged in operational duties and in training. They are also used by civilians engaged in activities where the risks of attack and assault

22、 are similar e.g. private security personnel, bullion handlers, escorts and couriers. These protectors are intended to reduce the severity of, or prevent, soft tissue injuries resulting from blunt trauma to the areas covered. Such blunt trauma can arise as the result of impact from airborne missiles

23、 (house bricks, assorted types of bottle, metal bars, pieces of timber, fragments of wood, broken glass and slates, etc.), or can be due to assault by individuals using weapons such as bars, baseball bats and pieces of timber, or caused by individuals kicking or making violent physical contact with

24、the wearers body These protectors are not intended to provide ballistic protection or protection against blows from sharp or pointed instruments (e.g. axes, spikes and knives). For certain user groups, including police and prison officers, the protectors constitute a second line of defence, with a p

25、ersonal defence shield providing a degree of primary protection (see BS 7971-3). Whilst shields do not always prevent impacts with the wearers body by missiles or weapons, they can reduce the energy of impacts to levels at which protectors can have a significant effect in the reduction of soft tissu

26、e or skeletal injuries. At times, however, circumstances can dictate that the shield is dispensed with or placed in a position which leaves the user exposed to a direct impact or assault. In these circumstances, and in the event of an unanticipated assault from behind, a torso protector and shoulder

27、 protectors can provide a level of protection from injury which the user would otherwise not have. Experience has shown that many areas of the body are at risk of impact in the attack scenarios described above. This standard specifies requirements and test methods for torso, shoulder, abdomen and ge

28、nital protectors. However, other areas of the body can also be at risk of impact in these attack scenarios, so protective clothing and/or equipment to protect these areas is also necessary. The test methods specified in this part of BS 7971 have been designed to measure the performance of torso, sho

29、ulder, abdomen and genital protectors with respect to the protection they can be expected to provide against the commonly-faced hazards listed above. The severity of these tests cannot compare directly with the conditions to which police officers, prison officers and other users can be exposed in re

30、al life situations, but experience has shown that protectors which pass such tests can significantly reduce the incidence and/or severity of injuries. The requirements for torso protectors for equestrian use specified in this part of BS 7971 are more stringent than those specified for protectors for

31、 horse riders in BS EN 13158:2000.BS 7971-8:2003 2 BSI 1 December 2003 1 Scope This part of BS 7971 specifies performance requirements and test methods for blunt trauma torso, shoulder, abdomen and genital protectors for use by police and prison officers and others who might be exposed to attack and

32、 assault in the course of their duties, for use in operational situations and in training. It specifies requirements for torso protectors for pedestrian use and for torso protectors for equestrian use. NOTE 1 Information and guidance on the use of these protectors is given in Annex A. NOTE 2 Guidanc

33、e on risk assessment and the selection, care and maintenance of protective clothing and equipment for use in violent situations and in training is given in BS 7971-2. This standard is not applicable to protectors intended to provide protection against ballistic or penetrating trauma (e.g. stabbing).

34、 NOTE 3 Such body armour is specified in Police Scientific Development Branch publications 1, 2 and 3. 2 Normative references The following referenced documents are indispensable for the application of this document.
