Grant funds can be found in a variety of expected and unexpected government sources. Typical funding for EMS programs, for example, can be found in your state's Department of Health, and Office of Traffic Safety or Department of Transportation. Your Department or Division of Forestry can help you locate and register for surplus government equipment and supplies. And, your Office of Emergency services, or in some cases State Fire Marshal, probably handles the Federal Emergency Management Agencies Hazard Mitigation Grant Program. These are but a few examples of typical fire related government funding.
Some states also have their own grant programs for fire and emergency service agencies.
In New Jersey, for example, the state offers funding for thermal imaging cameras. To locate available grants, you need to become familiar with all of the agencies at the federal and state level. You can do this through the Internet. Most agencies have an established Web site dedicated to providing information. Your job as a grant researcher is to go through every agency and locate their grant programs.
