Does Salt Put Out Fire

Fire has captivated and threatened humanity throughout history. It also demands innovative approaches for its control before you have time to call the local fire department. Among the myriad of substances explored for fire suppression, common salt you have in the kitchen cupboard, specifically sodium chloride, has emerged as a remarkable contender.

Harnessing the properties of this common household ingredient, scientists and firefighters have investigated its potential as a fire suppressant, raising the question: Can table salt put out fire? Sodium chloride, commonly known as table salt, is a crystalline compound composed of sodium and chlorine ions. Its ability to extinguish flames lies in its unique characteristics and chemical reactions when exposed to fire.

Salt has a high melting point and requires substantial heat to break down into constituent ions. When introduced to an open flame or high temperatures, salt crystals absorb heat, resulting in a chemical reaction that releases sodium and chlorine ions. These ions disrupt the fire triangle by inhibiting the combustion process.


While sodium chloride shows promising fire-suppressing properties, it is essential to acknowledge its limitations. Salt is most effective against small fires and may not be sufficient for large-scale infernos. Its effectiveness can vary depending on the fire’s nature, heat sources, and how much oxygen are available. Understanding these factors is crucial for employing salt as a firefighting tool safely and effectively.

Why Is Salt A Good Choice For Fighting A Fire?

Salt, a ubiquitous mineral found abundantly in nature, possesses remarkable properties, making it an excellent non flammable choice for firefighting. When salt is used in fire suppression, it undergoes a series of chemical transformations that help extinguish the flames and prevent re-ignition.

This inherent ability of salt to smother fires and cut off the oxygen supply to inhibit their rekindling has made it an invaluable tool in firefighting.

What Happens When You Burn Salt?

When salt is exposed to absorbing heat from the fire, it undergoes endothermic decomposition. With high heat, salt breaks down into its constituent elements, sodium, and chlorine. As the sodium atoms become energized, they release electrons and produce a vibrant yellow flame, characteristic of burning sodium (sodium oxide).

While the flame generated by burning salt may initially seem counterintuitive, it serves a vital purpose. As the sodium atoms release energy as light, the heat required to sustain the fire is significantly reduced. The fire is deprived of the heat necessary for its survival, leading to a rapid decrease in temperature and a subsequent extinguishing effect.

Can You Use Sea Salt To Put Out A Fire?

Sea salt, often hailed for its culinary uses and mineral-rich composition, is a variation of salt derived from the evaporation of seawater. However, sea salt shares similar chemical properties with common table salt, and its effectiveness in fire suppression varies significantly. Because of impurities and trace elements in sea salt, its combustion characteristics may deviate from common salts.

In firefighting applications, precisely controlling chemical reactions ensures optimal extinguishing efficiency. The impurities in sea salt introduce unpredictability into the combustion process, potentially compromising the effectiveness of the fire service. As a result, relying on sea salt as a primary fire extinguishing agent may prove unreliable and less efficient compared to fresh water or standard salt’s consistent performance.

Why Don’t Firefighters Use Salt Water To Put Out Fires?


While sea water contains dissolved salt, its utilization as a fire suppressant is discouraged in firefighting practices. The only reason is the corrosive nature of saltwater, which can inflict extensive damage to equipment and structures affected by the fire.

The high salt content in saltwater poses challenges, including increased conductivity and short circuits in electrical systems. This is the main reason salt water isn’t used as one of the primary kitchen fire extinguishers.

Is It Better To Use Salt Rather Than Baking Soda?

Salt, scientifically known as sodium chloride (NaCl), demonstrates exceptional fire-extinguishing capabilities because of its chemical composition. When exposed to high temperatures, salt undergoes an endothermic decomposition process. This process absorbs heat from the fire, significantly reducing its temperature and inhibiting its ability to sustain combustion.

The chemical reaction between salt and fire involves the dissociation of sodium chloride into sodium ions (Na+) and chloride ions (Cl-). The energized sodium atoms emit a vibrant yellow flame as they release energy, effectively starving the fire of the heat it needs to continue burning. This combustion characteristic of salt renders it a potent and reliable fire suppressant.

Baking Soda: Limited Extinguishing Potential

Baking soda (and baking powder), or sodium bicarbonate (NaHCO3), is a commonly recommended household ingredient for fire suppression. While baking soda can smother small fires, it falls short compared to salt because of its inherent limitations. When baking soda is exposed to heat, it undergoes a chemical reaction known as thermal decomposition. This reaction produces carbon dioxide (CO2), water (H2O), and a residue called sodium carbonate (Na2CO3).

Although the carbon dioxide generated can suppress flames by displacing oxygen, the efficacy of baking soda in extinguishing larger fires is limited.

Can You Use Flour Instead Of Salt?

Flour, predominantly composed of starch, is commonly found in kitchens. However, it is ill-suited for fire suppression purposes. When exposed to fire, flour can ignite and contribute to spreading flames, exacerbating the situation rather than extinguishing it. The explosive nature of flour makes it unsuitable and unsafe as a fire extinguishing agent. (Learn How To Turn Off Fire Alarm In Apartment Building)

Would Salt Put Out An Electrical Fire?

Regarding electrical kitchen fires, it is crucial to prioritize safety and follow recommended protocols. Using salt as an extinguisher for electrical fires is highly discouraged and dangerous. Salt is an electrical conductor and can exacerbate the situation by providing a path for electricity to travel.

In an electrical fire, it is essential to cut off the power source and use appropriate fire extinguishers designed explicitly for Class C fires, like carbon dioxide (CO2) or dry chemical extinguishers.

Does Salt Put Out A Grease Fire?

Grease fires can occur in kitchens and pose a significant risk because of the high temperatures and volatile nature of cooking oils and fats. So, can you put salt on a grease fire? Salt is not recommended for extinguishing grease fires.

When salt is introduced to a grease fire, it can cause splattering, making the fire worse and potentially causing injuries. Instead, following the “smother and suffocate” technique is advisable to cut off the air when dealing with a grease fire risk.

Can You Use Salt In A Large Kitchen Fire?

While salt to put out a fire is not recommended for extinguishing grease fires, it can be used as a preventative measure in kitchen environments to minimize the risk of fire incidents. Placing a thin layer of salt on the bottom of a pan or skillet before cooking can help absorb any potential grease splatters and prevent them from igniting.

However, it is essential to emphasize that this technique should not replace proper fire safety measures, including monitoring cooking activities and keeping a functional fire extinguisher nearby.

Can Rock Salt Catch Fire?

Rock salt, also known as halite. In winter, they throw salt to melt ice on roads besides seasoning in cooking. However, regarding its flammability, it is crucial to understand its properties and potential risks. Salt can burn for a few seconds before it cools again.

Understanding the Composition of Rock Salt

Rock salt (Himalayan Rock Salt or Pink Salt) is primarily composed of sodium chloride (NaCl), a non-combustible compound that does not support or contribute to the spread of flames. This means that rock salt does not catch fire under normal circumstances.

Factors That Influence the Flammability of Rock Salt

While rock salt is not flammable, it is essential to consider external factors may lead to the ignition or combustion of materials in contact with rock salt.

  1. Impurities: Rock salt obtained from natural sources may contain impurities that could have flammable properties. However, these impurities are typically present in trace amounts and do not significantly affect the overall flammability of rock salt.
  2. Moisture: Rock salt has hygroscopic properties, which can absorb moisture from the surrounding environment. Moisture can act as a catalyst for fire if it comes into contact with flammable materials near rock salt. Storing rock salt away from potential ignition sources and flammable substances is crucial.

In the event of a fire, knowing how to smother the flames promptly and effectively can prevent escalation. Here are some tried-and-true techniques for fire smothering:
