Fire Prevention

Fires can occur anywhere, at any time, and even minor incidents can have severe consequences. To prevent fires, it is essential to understand the elements required for a fire to ignite and sustain itself, which include oxygen, fuel (e.g., paper or wood), heat, and a chemical chain reaction. Once ignited, a fire will continue to burn until at least one of its components is removed, either naturally or by extinguishment (e.g., fire extinguisher or sprinkler system). By staying alert and following safe practices, you help protect yourself, your colleagues, and our broader community, as well as safeguard University property.

Visit the Âé¶¹´«Ã½ Fire Prevention Program to learn about identifying and reducing potential fire hazards associated with your work and across campus.

Did you know?

According to the U.S. Bureau of Labor Statistics (BLS), workplace fires and explosions lead to more than 5,000 injuries and 200 deaths a year. The most common injuries sustained include skin burn injuries, broken bones, lung damage due to smoke inhalation, cuts, lacerations, concussions, other traumatic brain injuries, and nerve damage.

Fire safety in the workplace

Fires can originate from many sources in the workplace and can spread rapidly in the right conditions. Below are the top causes of workplace fires and how to prevent them: 

  • Hot work (34%) - Welding, cutting, and brazing create flames and sparks. Always follow the Âé¶¹´«Ã½ Hot Work Program by obtaining a permit, inspecting the area for hazards, and assigning a fire watch. 
  • Cooking equipment (30%) - Never leave appliances like microwaves and toaster ovens unattended when in use. Plug them directly into wall outlets, not extension cords or power strips.
  • Electrical equipment (22%) - Check cords, plugs, and power strips regularly. Replace damaged items and avoid overloading circuits.
  • Combustible materials - Keep work areas clear of cardboard, wood, and other combustibles. Dispose of trash often and keep fire equipment accessible.
  • Flammable liquids - Store aerosols, paint thinners, and other flammables in approved storage cabinets. Keep these areas clear of clutter and equipment.

Portable space heaters

Portable space heaters are responsible for many fires and are generally prohibited on campus due to the risk of fire and overloading electrical circuits. In addition, these devices can reach extremely high temperatures and may cause burns if touched or placed near combustible materials. If your work area has inadequate heat, contact Environmental Health and Safety at ehs@northwestern.edu

Responding to a fire

Follow the C.A.R.E. method if you discover fire or smoke:

  1. Contain the emergency by closing all doors
  2. Activate the nearest fire alarm
  3. Report the fire from a safe location by calling 911
  4. Evacuate the building using the nearest and safest exit - if trained, extinguish the fire

Training

Portable fire extinguisher training equips you with the knowledge and confidence to act quickly in the event of a fire, helping prevent small incidents from becoming major emergencies.

Stay current with your annual online  if required by your school or unit. Those working in higher-risk areas (e.g., with gasoline or welding) may also need to complete
