Liquid fires pose a significant threat to both property and lives. Recognizing the potential hazards and implementing preventive measures is crucial to minimizing the risk of these destructive incidents.
Due to the nature of their source, they have the ability to spread quickly and cover a large surface area. They also release toxic fumes, which can be harmful both in the short and long term for firefighters.
Liquid fires are so notoriously difficult to fight that scientists have even researched and come up with nonflammable liquid fuels. That said, there are many industries and fields that will continue to use the same dangerous, flammable materials.
Thus, in this article, we will seek to understand how and why liquid fires begin and what preventive measures exist to safeguard against disasters.
1. Improper Storage and Handling of Flammable Liquids
One of the primary contributors to liquid fires is the improper storage and handling of flammable liquids. There are three key aspects when it comes to improper handling. These deal with how flammable liquids are stored, identified, and handled.
Unsafe Storage Practices
Flammable liquids stored near to ignition sources or in areas lacking proper ventilation significantly increase the risk of fires. In industrial settings or even in households, failure to adhere to safe storage practices can lead to catastrophic consequences.
Adequate storage involves keeping flammable liquids away from potential ignition sources, such as open flames, sparks, or hot surfaces. Proper ventilation is also crucial to dissipate any flammable vapors that may accumulate.
Inadequate Labeling
Properly labeling containers that hold flammable liquids is a critical aspect of risk reduction. Without clear and accurate labels, workers or individuals may not be aware of the contents, leading to mishandling or improper storage.
The importance of following established labeling techniques cannot be overstated, as it plays a pivotal role in preventing accidental spills or leaks that may result in a liquid fire.
Mishandling
Improper handling techniques, such as using unsuitable equipment or neglecting safety procedures, can lead to spills or leaks of flammable liquids. Sometimes, mishandling can also worsen the situation. For instance, an individual not trained in handling liquid fires may rush to get water. This is one of the worst things you can do, as water should never be used when fighting a liquid fire.
In workplaces where these flammable liquids are commonly used, training and implementing strict protocols for handling will be crucial.
2. Ignition Sources and Electrical Hazards
The presence of ignition sources and electrical hazards is another factor contributing to liquid fires. Understanding and mitigating these risks is vital for overall fire prevention.
Naked Flames
Open flames, whether from welding operations, candles, or other sources, pose a direct threat when in close proximity to flammable liquids. It is crucial to establish strict safety measures to prevent the occurrence of naked flames near these substances.
This may involve creating designated areas for activities involving open flames and enforcing strict no-smoking policies in areas where flammable liquids are present.
Faulty Electrical Equipment
Electrical systems that are not up to code or poorly maintained can lead to sparks or electrical malfunctions, igniting flammable liquids. This is why regular inspection, maintenance, and adherence to electrical safety codes are imperative to reduce the risk of electrical hazards.
Implementing ground-fault circuit interrupters (GFCIs) and ensuring the use of explosion-proof electrical equipment in relevant areas are additional measures to enhance safety.
3. Inadequate Fire Safety Measures and Emergency Preparedness
A lack of proper fire safety measures and emergency preparedness can also exacerbate the consequences of liquid fires. Addressing these deficiencies is crucial for minimizing damage and ensuring a swift response in the event of an incident.
Lack of Fire Extinguishers
Insufficient availability or improper maintenance of fire-extinguishing equipment is a serious shortcoming in many settings. Adequate and strategically placed fire extinguishers, suitable for dealing with liquid fires are a must.
Likewise, regular maintenance and employee training on the proper use of fire extinguishers are integral components of an effective fire safety plan.
Emergency Exit Obstructions
In the chaos of a fire, obstructed emergency exits can be life-threatening. Clear and unobstructed emergency exits are fundamental to ensuring the safe evacuation of occupants in the event of a liquid fire.
Regular inspections to identify and remove any obstructions, coupled with employee training on emergency evacuation procedures, will be vital to safeguarding lives. According to Parker Young Construction, you want to have inspections done at least once a year. That said, if you are in a particularly risky industry, even twice or three times is better.
How Are Liquid Fires Dealt With?
Now that we know the many ways that liquid fires occur, it’s important to also know how to deal with them. While there are several fire-suppression methods out there, foam happens to be one of the most commonly used ways to fight liquid fires.
The unique ability of foam to form a durable film over the liquid surface separates the fuel from the oxygen, thereby interrupting the combustion process.
AFFF, or ‘Aqueous Form Filling Foam’ in particular, contains fluorochemical surfactants that enhance the film-forming characteristics, making it suitable for use on hydrocarbon-based liquid fires. This might include fires caused by gasoline or oil.
However, one critical drawback of AFFF is its toxicity. It has been proven to cause a number of serious health issues among those exposed to the substance. TruLaw notes that AFFF contains ‘PFAS,’ a group of chemicals that are known to cause cancer and other serious health issues.
This is why countless firefighters are seeing legal recourse and hoping that the AFFF lawsuit settlement amounts can pay for their medical bills.
As a result, there has been a push away from AFFF toward other options, like C02 suppression. The inert gas acts by displacing oxygen, effectively smothering the fire and preventing its further escalation.
In conclusion, preventing liquid fires requires a comprehensive approach that addresses the common causes discussed above.
By implementing the steps detailed in this article, individuals and organizations can significantly reduce the risk of liquid fires.
Taking proactive measures, such as regular training, inspections, and maintenance, is essential to creating a safe environment and protecting lives and property from the devastating consequences of liquid fires.
