Indoor Firing Ranges IFR within DND are typically used by Canadian Forces CF personnel, Cadets, RCMP, and civilian organizations for firing small bore weapons in support of both operational occupational and recreational requirements. As indoor ranges are an enclosed space, control measures must be in place to ensure that contaminants generated during weapons firing are kept within acceptable exposure limits. The contaminant of most concern when firing a weapon in an enclosed space is lead. During firing lead from the round is physically chaffed off as the round passes down the barrel and further lead is released as the round strikes the backstop. All of this contributes to the presence of airborne lead and exposure to a contaminant which can cause a major respiratory health concern. Thus, it is important to ensure that lead exposures are kept As Low As Reasonably Achievable ALARA through the consistent, thorough evaluation of all aspects of an IFR. Assessment of the potential lead exposure, within an IFR, requires an evaluation of the current cleaning procedures, sanitation practices of users, assessment of IFR ventilation, air monitoring of lead concentrations, and monitoring of blood lead levels of personnel when required. Due to the potential health implications it is essential that inspections of FR be complete. Thus, this guideline has been written with the intention of providing a comprehensive step by step methodology for evaluating IFRs within DND. It is intended for use by Preventive Medicine Technicians PMed Techs who are aware and comfortable with the principles and practices of Industrial Hygiene specifically those trained in the use and handling of air sampling pumps velometers calibrators and, the general concepts of conducting an Indoor Firing Range survey.
