Smartphones are quickly taking over the US cellular phone hardware market — iPhone, Droid, Blackberry, Palm, just to name a few brands. With their advanced computing capability, smartphones are enabling users to perform more and more tasks on their phone than just the simple calling and texting. This computing power is harnessed by “apps,” which are application software programs used on smartphones.
For the fire investigator, the smartphone can become a handy tool in your daily work, but only if you know how to outfit it. This article highlights some of the core apps that fire investigators can use every day to assist in managing their investigative and administrative work. One caution before we begin: the investigator should be aware that any investigative information kept on your smartphone is not secure and also may be discoverable in a future legal proceeding. For that reason, we’ve confined the discussion of apps in this article to those where case-based investigative information is not stored or shared. At all times, exercise the utmost caution with investigative information.
Most weather apps have auto location based on the GPS signal from your phone, meaning that the app knows where you are and provides the weather data for that location. You can also lookup weather for a different area and program a favorites list for different locations you travel to repeatedly. Mapping Mapping applications, many of which are GPS-based, have both administrative and investigative value. Using the GPS in the phone and the mapping app, you are able to:
Mapping can also be used in other apps that help you find traffic, tides, mass transit, or parking information.
Remember that any information gleaned from one of these apps should be verified with another source. Roads change, streets are temporarily closed, and other events occur that may make the situation on the ground not the same as it is in a published map.
Administrative Management There are a wide variety of management and productivity apps that can help you organize your daily tasks, including:
Take a little time to think about the administrative tasks you do every day and then search the available apps for your device to see what’s out there to help you manage and streamline the administrative process. Incident Management There are several Incident Command System apps that can help the investigator handle large incidents, including the National Incident Management System (NIMS) components, concepts, and planning forms. Some of the ICS apps also provide an interactive look at the chain of command structure, which can assist with proper reporting at the scene. Scene Safety There are a number of apps available, and more are under development, that assist the investigator in working safely at the scene. Some examples of currently available scene safety apps include:
These apps can assist in identifying hazards at the scene and provide information on how to respond to the identified hazard.
Locators There are a number of locator apps available that can help the investigator find businesses nearby. Some locator apps also provide ratings and reviews for these businesses. A locator app works by using the GPS in the smartphone to determine your location, and then searching a database of nearby businesses that fit the criteria you enter, which is typically a category of business or government, and sometimes augmented with additional search filters, such as distance, price, or number of “stars.” These locator apps can be extremely helpful when you are not familiar with the location and can assist you in both physical comfort and investigative ways.
Some examples of what you can find with locator apps include:
There are also people locator apps, including offender and sex offender locator apps.
You should be aware that the locator app databases may not be definitive or complete and any information should always be confirmed with another source.
There are thousands of apps and more are being released every day. Set aside some time to browse through the apps available for your smartphone and think through how they might assist you in the field. Be sure to keep your apps up to date and periodically look for new apps that have been released and may be beneficial to you. Put your smartphone to work for you and you can work more efficiently, safely, and thoroughly.
