The AskRail app is a hazardous materials safety tool specifically designed for first responders who are the first on the scene or directly support the first responders in the event of a rail incident. This app is available for iPhone users and is free to download and use.

The main purpose of AskRail is to provide first responders with vital information about the contents of railcars involved in an incident. This information can be accessed by querying the railcar based on its equipment number. However, it's important to note that access to certain features, including querying railcar contents, is restricted to authorized personnel only.

In order to gain authorization to use these restricted features, first responders must go through a process that involves asserting their status as a first responder, providing information about their emergency response agency, and identifying a supervisor who can verify their duties. Additionally, sponsorship from a Class I railroad is required, which can take several weeks to obtain.
