Can A Fire Extinguisher Kill You? Case Studies And Real-Life Incidents

Although rare, documented cases exist where fire extinguishers have caused harm or fatalities. By examining these incidents, valuable insights can be gained to enhance safety measures.

For instance, in one case, a faulty fire extinguisher experienced an unexpected explosion during discharge, causing injuries. Another incident involved a person inhaling toxic fumes from a discharged fire extinguisher, resulting in respiratory distress.

These cases underscore the importance of proper handling, maintenance, and awareness to prevent similar incidents.

Analyzing the factors contributing to these incidents reveals various causes, including lack of maintenance, improper usage, and inadequate training.

It is crucial to emphasize that these cases are exceptions rather than the norm. Nevertheless, they highlight the significance of responsible use and the need for continuous improvement in fire safety protocols.

Types of Fire Extinguishers With Impact On Human Health

There are many types of fire extinguishers found around us. But the most common is 5.

Types of Fire Extinguishers With Impact On Human Health

If we analyze their ingredients and see the impact of these ingredients on the human body then it will be easy for us to determine whether they are human killers or not.

Wet Chemical Fire Extinguishers

  • Ingredient: Wet chemical agent (typically a potassium-based solution)
  • Function: Wet chemical agents create a foam that suppresses fires by cooling the flames and forming a soapy layer to prevent re-ignition.
  • Health Impact The wet chemical agent used in these extinguishers is generally safe for humans. However, prolonged exposure or ingestion may cause irritation to the skin, eyes, or respiratory system. It is important to follow proper safety precautions and avoid direct contact.
  • Can It Kill Humans No, wet chemical fire extinguishers do not kill humans. However, direct exposure or ingestion can do the above harm.

Water Fire Extinguishers

  • Ingredient: Water
  • Function: Water extinguishers work by rapidly cooling and suppressing Class A fires, primarily fueled by ordinary combustible materials.
  • Health Impact: Water is non-toxic and does not pose significant health risks. However, it is important to consider the risk of electrical shock when using water fire extinguishers near electrical equipment or live electrical sources. Avoid using water extinguishers on flammable liquid or electrical fires.
  • Can It Kill Humans: Never, but be careful about the electric fire.

CO2 Fire Extinguishers

  • Ingredient: Carbon dioxide (CO2) gas
  • Function: CO2 extinguishers displace oxygen, smothering the fire and interrupting the combustion process.
  • Health Impact: Carbon dioxide is generally safe for humans in small quantities. However, exposure to high concentrations of CO2 can lead to asphyxiation.

It is crucial to use CO2 extinguishers in well-ventilated areas and avoid prolonged exposure to high concentrations.

  • Can It Kill Humans: No, but if used improperly or in a confined space, CO2 fire extinguishers can displace oxygen and cause asphyxiation, potentially leading to fatalities.

Foam Fire Extinguishers

  • Ingredient: Aqueous film-forming foam (AFFF)
  • Function: Foam extinguishers create a barrier that separates the fuel from the oxygen, suppressing the fire and preventing re-ignition.
  • Health Impact: The ingredients used in foam fire extinguishers can vary, but they typically include surfactants, hydrocarbon solvents, and water. The foam itself is generally non-toxic.

However, some foam concentrates may contain chemicals that can cause skin or eye irritation. It is advisable to follow safety guidelines and avoid direct contact with the foam concentrate.

  • Can It Kill Humans: No, Foam fire extinguishers, when used properly, do not pose a direct risk of fatality to humans

Dry Powder Fire Extinguishers

  • Ingredient: Dry chemical powder (such as monoammonium phosphate or sodium bicarbonate)
  • Function: Dry powder extinguishers work by interrupting the chemical reaction of the fire, creating a barrier between the fuel and the oxygen.
  • Health Impact: The dry chemical powders used in these extinguishers can cause respiratory irritation if inhaled in large quantities. Some dry powders may also be abrasive, potentially causing eye or skin irritation.

Proper personal protective equipment, such as goggles and masks, should be used when operating dry powder extinguishers.

  • Can It Kill Humans: No, but if dry powder fire extinguishers are inhaled in large quantities, can cause respiratory irritation.

While the ingredients used in fire extinguishers may have some potential health impacts, they are generally considered safe when used properly and in accordance with manufacturer instructions.

However, it is important to exercise caution, follow safety guidelines, and seek medical attention if any adverse health effects occur.

Are Fire Extinguishers Safe to Use or Can They Be Dangerous?

Symbols on fire extinguishers play a vital role in ensuring safety. These universally recognized icons guide users on which type of fire they can effectively combat. While fire extinguishers are generally safe to use, it’s crucial to follow proper handling guidelines and precautions. Mishandling or using the wrong extinguisher type can pose certain risks, emphasizing the importance of understanding the symbols on fire extinguishers.

Potential Safety Precautions While Using Fire Extinguishers

When using fire extinguishers, it is crucial to follow these safety precautions. By adhering to these safety precautions, you can effectively use a fire extinguisher while minimizing risks to yourself and others.

Potential Safety Precautions While Using Fire Extinguishers
  • Assess the situation: Before attempting to use a fire extinguisher, evaluate the fire’s size and whether it is safe to extinguish. If the fire is spreading rapidly or the environment is unsafe, evacuate and call emergency services.
  • Know your extinguisher: Familiarize yourself with the type of fire extinguisher you are using and understand its proper application. Different extinguishers are suitable for specific fire classes, so use the appropriate one for the type of fire you are dealing with.
  • Maintain a clear exit: Always ensure you have a clear and unobstructed path to an exit before attempting to extinguish a fire. If the fire becomes uncontrollable or poses a threat to your safety, leave immediately.
  • Stand at a safe distance: Maintain a safe distance from the fire while using the extinguisher. The recommended distance is typically between 6 and 8 feet (1.8 to 2.4 meters) to avoid exposure to heat and flames.
  • Aim at the base of the fire: Direct the extinguisher’s nozzle or hose at the base of the flames, not at the top. This targets the fuel source and helps smother the fire effectively.
  • Use the P.A.S.S. technique: Remember the acronym P.A.S.S. to operate the extinguisher effectively:
    • Pull the pin: Pull the pin or safety clip to unlock the extinguisher.
    • Aim low: Point the nozzle or hose at the base of the fire.
    • Squeeze the handle: Squeeze the handle or lever to release the extinguishing agent.
    • Sweep side to side: Sweep the extinguishing agent from side to side, covering the base of the fire.
  • Evacuate if necessary: If you are unable to extinguish the fire or if it starts to grow rapidly, evacuate immediately. Safety should always be the top priority.
  • Alert others and call emergency services: Inform others nearby about the fire, activate the fire alarm if available, and call emergency services to report the situation.
  • Do not turn your back on the fire: After using the fire extinguisher, continue to monitor the area to ensure the fire does not reignite.

Leave firefighting to professionals: It is important to remember that fire extinguishers are meant for small, manageable fires. In the case of large or spreading fires, it is best to evacuate and let trained firefighters handle the situation.


Fire extinguishers are indispensable tools for fire safety, but it is crucial to recognize and address their potential hazards. By understanding the types and components of fire extinguishers, users can make informed decisions during emergencies.

Adhering to safety precautions, such as proper training, maintenance, and wearing protective gear, significantly reduces the risks associated with fire extinguishers.
