If A Laboratory Fire Erupts Immediately

Navigating the chaotic aftermath of a laboratory fire demands swift, decisive action. Your preparedness and response in the immediate moments can significantly impact the severity of the damage, the safety of personnel, and the overall recovery process.

Initial Steps: Prioritizing Safety and Immediate Response

When a fire erupts, the initial response should revolve around ensuring safety and containing the situation. Here’s a breakdown of crucial steps:

1. Activate the Alarm: Immediately trigger the building's fire alarm system. This alerts everyone in the facility, giving them ample time to evacuate. Make sure you're familiar with the location of alarm pull stations within your lab.
2. Evacuate Immediately: Your life and the lives of others are paramount. If the fire is small and manageable and you are trained to use a fire extinguisher, you might attempt to extinguish it. However, if the fire is spreading rapidly, producing thick smoke, or you are unsure of what to do, evacuate immediately. Close doors behind you as you leave to help contain the fire.
3. Call Emergency Services: Once you are a safe distance away from the building, call emergency services (911 in the US, 999 in the UK, 112 in Europe, or your local emergency number). Provide them with the exact location of the fire, the type of laboratory, and any specific hazards you know about (e.g., chemicals involved).
4. Account for Personnel: Once outside, gather at a designated meeting point and account for all lab personnel. Report any missing individuals to the emergency responders immediately. Do not re-enter the building under any circumstances until authorized by fire officials.
5. Stay Upwind: Smoke inhalation is a serious threat. Position yourself upwind of the building to avoid breathing in harmful fumes and gases.

Fire Extinguisher Use: A Calculated Decision

Deciding whether or not to use a fire extinguisher depends on several factors. Misusing a fire extinguisher can exacerbate the situation. Here's what to consider:

• Size of the Fire: Only attempt to extinguish a small, contained fire. If the fire is already spreading to nearby equipment or materials, it's too large to handle with a portable extinguisher.
• Type of Fire: Different classes of fires require different types of extinguishing agents. Using the wrong type of extinguisher can be ineffective or even dangerous. Common fire classes include:
  • Class A: Ordinary combustibles like wood, paper, and cloth.
  • Class B: Flammable liquids like gasoline, oil, and solvents.
  • Class C: Electrical fires involving energized equipment.
  • Class D: Combustible metals like magnesium, titanium, and sodium.
  • Class K: Kitchen fires involving cooking oils and fats.
• Your Training: You must be properly trained in the use of fire extinguishers before attempting to put out a fire. Training should include hands-on practice and instruction on the different types of extinguishers and their proper applications.
• Your Escape Route: Ensure you have a clear and unobstructed escape route before attempting to extinguish a fire. Never let the fire block your exit.

Using a Fire Extinguisher (PASS):

If you decide to use a fire extinguisher, remember the acronym PASS:

• Pull the pin: This unlocks the operating lever and allows you to discharge the extinguisher.
• Aim at the base of the fire: Aiming at the flames is ineffective. You need to target the fuel source to extinguish the fire.
• Squeeze the lever: This releases the extinguishing agent.
• Sweep from side to side: Cover the entire area of the fire with the extinguishing agent.

Even if you successfully extinguish the fire, notify emergency services. They can assess the situation and ensure there are no hidden embers or hazards that could reignite the fire.

Understanding Laboratory-Specific Fire Hazards

Laboratories present unique fire hazards due to the presence of flammable chemicals, specialized equipment, and often, compressed gases. Being aware of these hazards is crucial for preventing fires and responding effectively if one occurs.

• Flammable Chemicals: Many chemicals used in laboratories are flammable, including solvents like acetone, ethanol, and ether. These chemicals can easily ignite if exposed to a spark or open flame. Proper storage and handling of flammable chemicals are essential.
