Job Description

Fire is one of nature’s most powerful forces. When it’s properly harnessed, fire is incredibly useful for things like cooking and heating. But when it’s out of control, few things are as destructive. Unfortunately, it is all too easy for harmful fires to get started due to human negligence or malicious intent. Fires can also be caused by accidental incidents such as overheated machinery or faulty electrical wiring. 

Because there are so many possible ways for fires to break out, many organizations utilize Fire Inspectors to screen buildings for potential hazards. Their role is to help prevent situations where fires could occur. Fire Inspectors do physical walkarounds to visually inspect residential and commercial properties, checking to ensure all applicable fire-related codes are being complied with (and to enforce codes when they aren’t being followed). Forest Fire Inspectors perform similar duties but related to outdoor environments and preventing wildfires. 

When unwanted fires do happen, Fire Investigators are brought in to assess the impacted area and determine how the fire — and any related explosions — got started. Like Inspectors, many Fire Investigators begin their careers as firefighters, then apply their accrued knowledge and skills to figure out the causes of fires and, when needed, help hold responsible parties accountable.

Expectations and Sacrifices

Fire Inspectors and Investigators must travel frequently to conduct site visits. Both roles have enormous responsibilities, with one helping to prevent fires and the other tasked to figure out how fires happened. An overlooked fire hazard could eventually lead to a devastating structure or forest fire, while a missed piece of evidence could prevent investigators from catching a serial arsonist. That’s why organizations and communities rely on the skills and diligence of these critical workers to keep people and property safe and to prevent future incidents. 

Current Trends

Two contrasting trends have been noticed in recent years — a decrease in fire frequency and an increase in fire temperatures and burn rates. Increased vigilance, aided by the work of Fire Inspectors, may be contributing to fewer fires, but the fires that do occur are burning hotter and faster because of changes in materials used for building construction and internal contents (such as furniture). 

There’s also a higher risk of building collapse, again due to materials used during construction. However, to help combat the risk, building owners have increased their usage of smoke alarms, sprinklers, and automatic system shutoff devices. 

Wildfires have been on the rise for some time, due to droughts and generally warmer climate conditions. These ravaging blazes can be extremely hard to contain, making prevention (through increased education and training) more important than ever. 

In terms of fire investigation, UAVs and technological advances such as computer fire modeling have helped improve results.

What kinds of things did people in this career enjoy doing when they were younger…

Fire Inspectors and Investigators may have enjoyed learning and following rules or helping to teach others about safety-related issues. Their concerns for safety could have stemmed from some event in their past, or simply out of their acute awareness of hazards and risks. They may have always exhibited a general sense of curiosity, wanting to find and solve problems or puzzles, too! 

Education and Training Needed

Education Needed

  • Per the American Library Association, ~20.7% of Fire Inspectors and Investigators hold only a HS diploma, 30.1% have some college (but no degree), 16.7% have an associate’s, 22.2% a bachelor’s, and 5% a master’s. 1.3% have a PhD
  • Fire Inspectors and Investigators frequently start out as firefighters. If starting as a firefighter: 
    • Firefighters don’t need a college degree but must be 18 years old and have a high school diploma or GED, plus some training in emergency medical services
    • Per the U.S. Fire Administration’s Fire and Emergency Services Higher Education Project, students may get a head start by taking relevant community college or vocational training courses in “building construction for fire protection, fire behavior and combustion, fire prevention, fire protection systems, principles of emergency services, principles of fire and emergency services safety and survival”
    • Many students earn a 60-credit associate’s in fire science to boost their credentials
    • Candidates must pass tests prior to acceptance into a fire academy program. Training takes 12-14 weeks and covers topics such as “firefighting, fire-prevention techniques, local building codes, emergency medical procedures”
    • Pre-acceptance testing includes a background check and interview plus:
    • Some departments require candidates to have EMT or paramedic certification
