This part of BS 7971 specifies performance requirements and test methods for foot and ankle protectors and foot protectors to provide protection against blunt trauma, for use by police and prison officers and others who might be exposed to attack and assault in the course of their duties, for use in operational situations and in training.<\/p>\n
\nNOTE 1 Information and guidance on the use of foot and ankle protectors and foot protectors is given in Annex A.<\/i><\/p>\n
NOTE 2 Guidance 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.<\/i><\/p>\n<\/blockquote>\n
