Do Firefighters Take A Polygraph Test? (& how to Pass)

If you want to become a firefighter, you need a clear idea of all parts of the examination process. Fire departments want to hire the best applicants, and the hiring process includes a variety of physical, mental, and background checks.

But do firefighters take a polygraph test? If so, do all fire departments require a polygraph to be a firefighter?

This guide has the answer, as well as tips on how to pass a firefighter polygraph if one is required by your fire department.

Let’s get started.

Do Firefighters Take a Polygraph Test?

Yes, some firefighters do have to take a polygraph test for pre-employment examination. Polygraph tests assist fire departments in verifying information about an applicant’s past and confirming their suitability for certain fire service positions.

What Is a Firefighter Polygraph Test?

A firefighter polygraph (also known as a lie detector test) is a psychophysiological examination used by some fire departments during the hiring process. It measures physiological responses like heart rate, respiration, and skin conductivity while asking the examinee a series of questions. The examiner then analyzes these responses to assess the examinee’s truthfulness and suitability for the role.

How Does a Polygraph Test Work?

Generally, the test will be divided into four three segments:

  1. Calibration: The examiner establishes baseline readings for each physiological response while asking neutral questions.
  2. Questioning: The examiner then asks a series of relevant and irrelevant questions. Relevant questions pertain to the subject’s honesty, while irrelevant questions are designed to gauge emotional response.
  3. Analysis: The examiner analyzes the recorded physiological responses, looking for significant changes compared to the baseline. These changes are believed to indicate deception.

Why Would Firefighters Need Polygraph Tests?

When applying for some fire service jobs, you may have to take a polygraph test as part of your background investigation. The legality and use of polygraph tests at fire departments vary widely across states and even within specific jurisdictions.

Here is an overview of the most common reasons why firefighters are given a polygraph:

Pre-Employment Screening and Internal Investigations

There are a lot of requirements that an applicant need to fulfill to become a firefighter. For example, there is a specific age limit for firefighters. And anyone can lie and claim that they meet these criteria. Through polygraph tests, fire departments can dictate whether the applicant has filled out every part of the employment application correctly.

Compliance With Regulations

Some fire departments must adhere to the regulations of the state that require them to make firefighter applicants take a polygraph test.

Security Clearance

Polygraph tests may be used by fire departments to assess whether the applicant is fit for a role that requires security clearance. Firefighter polygraph tests can uncover potential security issues such as sabotage, espionage, and terrorist activities.

Evaluating Fitness for Duty

Although not common, some departments may use polygraph tests to determine the firefighter’s fitness level. For example, questions during the exam can check whether the applicant has a disability that was not disclosed on the application form that could make them unfit for the fire service role.

Incident Investigations

Other than a pre-screening examination for employment, fire departments may also use polygraphs to investigate a particular incident with employed personnel. Firefighter polygraphs can determine the level of truthfulness during fire scene investigations.

Common Types of Questions Asked During a Polygraph Test for Firefighters

The questions asked during a polygraph test will vary from one department to another. And the questions will also depend on the context of the test. But, in general, these are common questions you may be asked by the examiner:

Personal History:

  • Have you ever been arrested or convicted of a crime?
  • Have you ever used illegal drugs?
  • Have you ever committed theft, arson, or any other act of dishonesty?
  • Have you ever falsified information on an application or resume?

Job-Related:

  • Have you ever violated any rules or regulations in a previous job?
  • Have you ever been involved in any incident that could compromise your ability to perform as a firefighter?
  • Why do you want to be a firefighter?
  • Are you willing to follow orders and work as part of a team?
  • Do you have any physical or mental limitations that could hinder your performance as a firefighter?

Control Questions:

  • Have you ever lied to someone in a serious matter?
  • Have you ever done anything that you would be ashamed to tell your family or friends?
  • Have you ever taken something that didn’t belong to you?

Additionally:

  • Expect a mix of open-ended and yes/no questions.
  • Questions may be repeated in different ways to assess consistency.
  • The examiner may ask follow-up questions based on your responses.

How to Pass a Fire Department Polygraph Test

It is impossible to guarantee passing a firefighter polygraph test because several factors are beyond your control. However, the following information and tips can help you approach the test with confidence and understanding, which will aid you in passing the fire department polygraph.

Understanding the Polygraph

  • Remember, the polygraph is one tool amongst many used to assess your suitability. It measures physiological responses, but its accuracy is debated and can be influenced by individual variations.
  • Focus on truthfulness and honesty throughout the test. Trying to “beat” the polygraph by using countermeasures is unethical and often ineffective.
  • Research your state’s laws and regulations regarding polygraph use in the hiring process. Some states have banned them in specific professions.

Preparing for the Test

  • Get a good night’s sleep and avoid caffeine or alcohol before the test as these can affect physiological responses.
  • Practice relaxation techniques like deep breathing and meditation to manage anxiety during the test.
  • Review common polygraph question formats and understand the difference between relevant and control questions.
  • Be familiar with your background and be prepared to answer truthfully about any past experiences or behaviors the test might inquire about.
  • Consult with an attorney or relevant professional if you have concerns about specific questions or the test’s legality in your region.

During the Test:

  • Be polite and cooperative, and answer questions directly and honestly.
  • Don’t try to volunteer unnecessary information. Respond only to the questions asked.
  • If you don’t understand a question, ask for clarification. Don’t guess or provide misleading answers.
  • Take breaks if needed to calm your nerves.
  • Remember, the examiner is not your enemy. They are simply conducting their job.

Additional Polygraph Tips

  • Focus on your strengths and qualifications as a potential firefighter. Showcase your dedication and commitment to the profession.
  • Highlight your positive experiences and contributions in previous roles.
  • Don’t dwell on past mistakes or negative experiences. Be honest and upfront if questioned, but focus on your growth and positive qualities.
  • Remember, the polygraph is just one part of the overall hiring process. Don’t let it define your candidacy.

Remember: Honesty and integrity are key qualities sought by fire departments. By approaching the polygraph test with confidence, preparation, and truthfulness, you can demonstrate your suitability for this important role.
