Why Emergency Evacuation Plans Are Critical for Laboratories
In the event of a fire or other emergency, seconds count. The ability to safely and efficiently evacuate a laboratory depends on having a well-structured emergency evacuation plan in place. Laboratories pose unique risks due to the presence of hazardous chemicals, equipment, and potentially infectious agents. Every individual working in a lab must take personal responsibility for understanding the evacuation procedures and acting promptly when an emergency arises. A clear, practiced plan not only saves lives but also minimizes potential damage to facilities and equipment.
Pre-Planning Your Laboratory Escape
Preparation is key to ensuring a safe evacuation. Follow these steps to pre-plan your laboratory escape:
Get training in Lab Crisis Preparation and earn CEUs.
One of over 25 IACET-accredited courses in the Academy.
Lab Crisis Preparation course
Locate Fire Alarm Pull Boxes: Know where the nearest fire alarm pull boxes are in your laboratory. Activating these alarms is the first step in alerting others to a fire or emergency.
Identify Two Exit Routes: Ensure that your lab floor has at least two unobstructed exit routes. These provide alternative ways out in case one exit is blocked.
Inspect Fire Exits: Regularly check fire exits to ensure they are accessible and functional. Exits should be free of clutter or obstructions.
Avoid Elevators: Never use elevators during a fire; they may malfunction or stop on a fire-affected floor, trapping occupants.
Find Fire-Rated Stairwells: Learn the location of fire-rated stairwells, which offer a protected path to the outside.
Familiarize Yourself with the Fire Alarm Sound: Fire alarms may sound like bells, chimes, horns, or a coded gong. Recognize the specific alarm used in your building to respond quickly.
Post Emergency Numbers: Place emergency contact numbers near all telephones for quick access.
Know How to Use Fire Blankets: If fire blankets are available in your lab, learn how to deploy them effectively.
Evacuation Procedure During a Fire or Alarm
When a fire or fire alarm occurs, everyone must evacuate immediately. Follow these steps:
Activate the Alarm: If you discover a fire or see smoke, activate the nearest fire alarm pull station to alert building occupants.
Leave Immediately: Do not assume the alarm is false or a test. Seconds count in emergencies, so evacuate without delay.
Assist Others If Safe: Offer help to those who may need assistance, such as individuals with mobility challenges, as long as it doesn’t endanger your safety.
Use the Nearest Stairway: Unless unusual conditions dictate otherwise, the best evacuation route is the nearest stairway leading to an exit.
Close Doors Behind You: Close (but do not lock) doors as you leave to help contain the fire. If doors lock automatically, take your key with you in case you need to seek refuge.
Assemble and Account: Once outside, proceed to your designated assembly point. Conduct a head count to ensure everyone is accounted for. If someone is missing, inform fire or police officials immediately.
Door Safety: Is the Door Hot?
Before opening any door during an evacuation, it is crucial to assess the situation for potential fire hazards. Taking the proper precautions can prevent dangerous encounters with flames or smoke and ensure a safer path to escape. By checking the door for heat and opening it cautiously, you can avoid worsening the emergency and safeguard yourself and others during the evacuation process.
- Check for Heat: Use the back of your hand to feel the door, door knob, or door frame. If any of these feel hot, do not open the door as there is likely fire on the other side.
- Open Slowly: If the door feels cool, open it slowly to check for smoke or flames before proceeding. Close the door behind you once you pass through.
Smoke Safety: Stay Low
If you encounter smoke while evacuating, it is essential to take immediate precautions to protect yourself from inhaling toxic fumes and ensure your safety. Smoke can impair visibility and breathing, making it critical to stay low to the ground where the air is clearer. Understanding how to navigate through a smoke-filled environment can significantly increase your chances of safely reaching an exit or a secure location.
- Crawl Low: Smoke rises, so the cleanest air is typically within 1 to 2 feet from the floor. Crawl or stay as low as possible to avoid inhaling toxic fumes.
- Use an Alternate Route: If the primary exit is blocked by fire or smoke, use your secondary route. If no safe route is available, return to a room and wait for rescue.
If You Can’t Escape
If evacuation is not possible due to blocked exits or heavy smoke, it is essential to take proactive measures to protect yourself while waiting for rescue. These steps can help you minimize exposure to heat and smoke and increase your chances of being located and safely evacuated by emergency personnel.
Close Doors: Shut all doors between you and the fire to slow its spread.
Seal Cracks: Use cloth or other materials to seal cracks around doors to keep smoke out.
Call 911: Inform emergency services of your exact location and situation.
Signal for Help: Signal from a window by hanging clothing, waving an object, or shouting to alert rescuers to your location.
Conclusion: Preparedness Saves Lives
A well-thought-out emergency evacuation plan tailored to the unique risks of a laboratory environment is crucial for ensuring the safety of all personnel. By pre-planning escape routes, familiarizing yourself with safety equipment, and understanding evacuation procedures, you can respond quickly and effectively during emergencies. Regular practice and adherence to these guidelines will help create a safer laboratory environment for everyone.
