WISER ( (Wireless Information System for Emergency Responders) is a mobile application currently available on the Palm, Pocket PC, and Microsoft Windows™ platforms (now including Windows Mobile Smartphone) designed to assist first responders in hazardous material incidents. A web-based WISER (WebWISER) is now available, supporting web browsers for both PCs and PDAs, including BlackBerry.

Developed by the National Library of Medicine (NLM), WISER provides a wide range of information on hazardous substances, including chemical identification support, physical characteristics, and human health, containment and suppression information.

When handling hazardous material incidents, first responders in general, and Hazmat (hazardous materials) units in particular, must make many decisions quickly. They need accurate information about the hazardous substances, the emergency resources available, and the surrounding environmental conditions. WISER can assist in identification of an unknown substance and, once the substance is identified, provide guidance on immediate actions necessary to save lives and protect the environment.
