A fire blanket serves as a safety device in laboratory environments, designed to manage small-scale fires or to smother flames on a person. These blankets are constructed from fire-resistant materials like woven fiberglass or treated wool. Their primary function involves depriving a fire of oxygen, thereby extinguishing the flames. This method offers a straightforward and fast-acting response to minor fire incidents, making fire blankets a vital tool for immediate protection in a lab setting.
Identifying Fire Blanket Locations
Fire blankets are positioned in laboratories for rapid accessibility during emergencies. Common placement includes areas near workbenches, chemical storage zones, and equipment that generates high heat, such as Bunsen burners or hot plates. They are typically wall-mounted in central, visible locations, often near laboratory exits or entrances. Clear signage at eye level indicates their presence, further aiding quick identification.
Fire blankets should never be blocked or concealed by equipment, furniture, or doors. The goal is to minimize retrieval time, ensuring personnel do not navigate obstacles. This positioning facilitates an immediate response to fire hazards.
Effective Use of a Fire Blanket
Utilizing a fire blanket effectively depends on the nature of the fire. For small fires on a workbench, such as those involving spilled flammable liquids, pull the blanket from its holder, unfold it, and use it as a shield while approaching the flames. The blanket is then gently placed over the fire, ensuring it completely covers the burning material to cut off the oxygen supply. The blanket should remain in place until the fire is extinguished and the area has cooled.
When an individual’s clothing catches fire, the procedure changes. The fire blanket should be quickly removed from its container and wrapped around the affected person to smother the flames. It is important not to wrap the blanket too tightly, focusing instead on covering the burning areas to extinguish the fire. While safety showers are often the preferred method for extinguishing clothing fires, a fire blanket can serve as an alternative, particularly if a shower is not immediately available or accessible.
Fire blankets are useful for situations where a fire extinguisher might be inappropriate, such as small grease fires or incidents near sensitive equipment that could be damaged by extinguisher residue. These blankets are single-use and should be replaced after any deployment.
Fire Blankets Within Broader Lab Safety
Fire blankets function as one component within a comprehensive laboratory safety system. They complement other emergency equipment, including fire extinguishers, emergency showers, and eyewash stations, each serving distinct purposes in addressing lab hazards. This integrated approach ensures that a range of tools are available to address various types of incidents, from chemical splashes to different classes of fires.
A comprehensive safety framework relies on proper placement and maintenance of all safety devices, as well as regular training for laboratory personnel. Understanding when and how to use a fire blanket, alongside other safety equipment, is communicated through routine safety drills and educational programs. This preparation allows for swift and coordinated action, preventing minor incidents from escalating into larger emergencies.
