The new release of the Wireless Information System for Emergency Responders, WebWISER 4.5, integrates content from the Chemical Hazards Emergency Medical Management (CHEMM) tool. Also, it updates the Emergency Response Guidebook (ERG) content to ERG's 2012 version. WebWISER is a system designed to assist emergency responders in hazardous material incidents.

CHEMM integration brings the following new features to WISER:

• New hospital provider and preparedness planner profiles, along with a customized home screen for all WISER profiles
• Acute care guidelines for six known mass casualty agents/agent classes
• The addition of a wealth of CHEMM reference material
