"Depending on the emergency event at hand, different emergency responder agencies may be first at the scene. Many times the cause of the incident is not known immediately and the emergency responder may have little, if any, information. Furthermore, emergency responders do not usually wear specialized clothing or bring specialized equipment needed to perform operations in an unknown threat environment. If an explosive device is present, emergency responders may be injured because their normal personal protective equipment (PPE) lacks explosive protection. Therefore, selection of equipment for explosive threat protection requires emergency responders to be aware of the capability of the protective products, any improvements made to these protective products over time, and areas where emerging technologies may be considered. This SAVER [System Assessment and Validation for Emergency Responders] Technology Guide offers insight into available resources to assist in the technology selection process and review of individual protection. Specifically, this guide outlines technologies and products that protect against the harmful effects of the blast overpressure and/or flying fragmentation caused by explosive devices. The focus is on body-worn PPE, emplaced mitigating equipment (e.g., flexible and/or inflatable barriers, and/or electronic explosive defeat devices), and emerging explosive protection technologies (e.g., materials and textiles). This guide does not include armored emergency response vehicles or explosive ordnance disposal (EOD) responder-specific equipment, such as bomb suits, robots, or other specialized equipment. Emergency responders need to consider their agency and individual needs when assessing individual blast overpressure and fragmentation protection."
