Purpose of App Review

There are few reference apps for hazardous materials personnel that are as detailed and accurate as WISER.

This review will highlight some of the key features of the apps functionality and content as well as its use in everyday work.


WISER is an app developed by the National Library of Medicine (NLM), a part of the National Institute’s of Health (NIH), and serves as a comprehensive reference guide for professionals responding to hazardous materials incidents. It is hard to tell when an app like this is needed as HAZMAT incidents usually occur unexpectedly.

WISER is an acronym standing for Wireless Information System for Early Responders. Professionals can look up a substance and get all the information they need regarding the broad dangers, the environmental impact, and finding emergency resources available in the area.

User Interface

The WISER interface is one based on simplicity. The homescreen gives the user four options: Search Known Substances, Browse By Category, Recent Substances, and About. The Search Known Substances option allows the user to quickly search for substance information by name instead of having to find it in the Browse By Category option, which offers exactly what it states.

The browsing option is the most detailed and robust feature of the app. It is layered with categories and broken down into very specific subjects and types of substances making it easy for a user to find what they are looking for with little confusion. Recent Substances on the homscreen offers a history of what the user has recently viewed in WISER.

Finally, the About option provides a link to get more information about WISER, its developers (NLM), and a link to a WISER support page on the web.

Evidence to Support Use

Research has taken place on developing standardized decision support systems for HAZMAT emergency situations [1]. With the rise of mobile technology and average use of mobile devices in medicine and healthcare rising, some companies and organizations have shifted to include on-the-go decision support to aid in minimizing the effect of HAZMAT incidents as early as possible [2].
