When dealing with fires, the correct way to suppress them is often the crucial difference between resolution and disaster. As suggested by the recent overview by Waterline Controls, not all fires are the same, and each one responds differently to extinguishing methods. One question often arises in such discussions: can you use water on a petroleum-based fire? Spoiler alert—not only should you avoid it, but doing so could worsen the situation and spread the fire.
What Type of Fire Can Be Put Out Safely with Water?
Water is the most widely available agent for extinguishing fires, but it cannot combat all fires. The effectiveness of water depends on the fuel that is burning. Fires are classified by their fuel source, which also determines how to extinguish them safely.
These Class A fires are probably the most common, such as wood, paper, and cloth, even plastics. With a campfire, a knocked-over candle, or when a fireplace accident causes something to catch fire, water is safe here since it cools and thereby removes the heat required for the fire to burn. Such incidents are usually resolved with a continuous flow of water without much effort.
However, when dealing with a Class B fire it’s a different story. You might wonder, can you use water on a petroleum based fire? The simple answer is no. Water can cause the petroleum to spread, making the flames grow larger and even more uncontrollable. The dangers skyrocket, which is why Class B fires require foam, dry powder, or carbon dioxide extinguishers instead.
Can You Use Water on a Petroleum Based Fire? Absolutely Not!
Petroleum and water do not mix. Water’s inability to suppress the flames comes down to basic science. Products such as gasoline, oils, and some alcohols are less dense than water and float on its surface. When water is applied to a petroleum-based fire, it spreads the flammable liquid outwards, potentially extending the fire to areas and materials not already affected.
In the event of an occurrence such as a fire in a garage ignited by leaking gasoline or oil, the use of water may cause the surrounding implements, walls, or sometimes even the whole structure to catch fire. Such cases can only be best solved by specialized extinguishers, such as foam extinguishers, to smother the flames by cutting off the oxygen supply. Sellers of fire-damaged properties should always be upfront if damage traces back to petroleum-fueled fires, as future mishaps could arise if the area is not properly restored.
Why Water Doesn’t Work for Class C, D, and K Fires
Moving beyond Class A and B, other types of fires require their own extinguishing protocols:
- Class C Fires involve electrical equipment. Water is a dangerous conductor of electricity. That is why spraying water on sparking wires or burning electrical outlets increases the chances for electrical currents to flow toward anyone near the vicinity. First, disconnect the electrical source. The fire may then become a Class A scenario if solid combustibles are involved.
- Class D Fires are rare and occur when combustible metals, like magnesium or titanium, ignite. Perchloric acid is very reactive, creating potential hazards with unknown chemicals. This can be anticipated using a proper standard operating procedure to minimize it.
- Class K Fires frequently occur in kitchens due to burning fats and oils. In such conditions, the aggressive splatter and its effect on the fire are consequences of water. However, wet chemical extinguishers are especially effective on kitchen-related mishaps.
The Importance of Understanding Fire and Restoration for Property Sellers
If you’re aiming to sell a property that has experienced fire damage, knowing the details of the incident is vital, not only for safety purposes but also to build trust with potential buyers. Buyers will want to know:
- The type of fire: Was it caused by a Class A mistake like a cigarette or candle, or something more involved like petroleum or electrical issues?
- The damage resolution: If water was improperly used the fire-and-restoration process may need adjustments due to possible water damage.
- Professional restoration services: Check if cleanup and repairs were done by trained specialists. A fire-damaged house seller should provide buyers with details of repairs, upgrades, and corrective measures taken.
Restoring a fire-damaged property is crucial for anyone looking to sell, as it helps rebuild trust and restore the home’s value. Engaging qualified professionals ensures the property is fireproofed against reoccurrence and made marketable. They also leave it homey and comfortable for the owners. The line between devastation and opportunity lies in how fire and restoration are handled and communicated.
