Laboratory environments come with inherent risks, making preparedness for medical emergencies a critical aspect of lab safety. From chemical burns to severe bleeding, swift and appropriate action can prevent injuries from worsening and, in some cases, save lives. This guide outlines essential steps to handle common medical emergencies in the laboratory, emphasizing first aid techniques, emergency protocols, and the importance of calling for professional help.

General Guidelines for Handling Laboratory Medical Emergencies

In any medical emergency:

Get training in Physical Hazards and earn CEUs.

One of over 25 IACET-accredited courses in the Academy.

Physical Hazards course

• Provide Immediate First Aid: Administer only the minimum necessary aid to prevent further injury until professional help arrives.
• Call 911 for Serious Injuries: If the injury is severe (e.g., requiring more than a bandage), call for emergency medical assistance.
• Stay Within Your Training: Avoid performing medical procedures you are unfamiliar with. Focus on stabilizing the victim within your scope of knowledge.
• Report All Incidents: Notify your supervisor or advisor once professional help has been contacted. Accurate documentation ensures future preventative measures can be implemented.

Responding to Specific Laboratory Injuries

1. Stoppage of Breathing

Lack of breathing, often caused by asphyxiation, electrical shock, or other physical trauma, is a critical situation that demands immediate and decisive action to prevent life-threatening consequences.

• Start rescue breathing (mouth-to-mouth) immediately. Seconds count—shout for help while resuscitating.
• Check for obstructions in the airway and ensure the victim is lying flat.
• Continue until professional help arrives or the victim begins breathing independently.

2. Severe Bleeding

Severe bleeding can often be controlled effectively by applying direct pressure to the wound and taking immediate action to prevent further blood loss and complications.

• Apply Pressure: Use a clean pad or cloth to press firmly on the wound. In emergencies, clothing can suffice.
• Elevate the Limb: Raise the injured area above the heart to reduce blood flow.
• Wrap for Shock Prevention: Keep the victim warm and lying down to avoid traumatic shock.
• Avoid Tourniquets: These can cause more harm than good unless applied by a trained professional.

3. Thermal Burns

Burns can range from minor to life-threatening injuries that require prompt action. Immediate cooling and proper care are crucial to minimize damage, alleviate pain, and prevent further complications.

Minor Burns:

• Apply cold water or ice packs to the area to reduce heat and inflammation.

Clothing Fires:

• Instruct the victim to stop, drop, and roll to extinguish flames.
• Avoid running to the safety shower; use a fire blanket if one is nearby.
• Once flames are out, deluge the burned area under a safety shower to cool the skin and wash away any chemical contaminants.
• Apply wet, ice-packed cloths to the burned areas and wrap the victim to prevent shock.
• Never use a fire extinguisher on a person—it’s for objects, not humans.

4. Chemical Burns

Chemical splashes can be particularly harmful and may result in serious injuries or burns. Immediate and thorough flushing with running water is essential to minimize damage and remove the harmful substance effectively.

Steps to Treat Chemical Burns:

1. Flush the Area: Use running water to wash away the chemical immediately.

2. Remove Contaminated Clothing: Continue to flush the skin while carefully removing any saturated clothing.

3. Eye Exposure: Flush the affected eye with clean water for at least 15 minutes, directing the stream away from the unaffected eye.

4. Body Exposure: Use a safety shower, hose, or faucet to flood the affected area with water for at least 15 minutes.

5. Large Area Contamination: Remove contaminated clothing while under the safety shower, prioritizing immediate treatment over modesty.

6. Safety Goggles: Leave goggles on until the surrounding area is thoroughly rinsed—they may be preventing further exposure.

5. Traumatic Shock

Traumatic shock can result from severe injuries, even if the symptoms aren’t immediately apparent, and it can quickly escalate into a life-threatening condition if left untreated.

Symptoms of Shock:

• Cold, clammy skin
• Paleness
• Disorientation or deliria

Treatment:

• Keep the victim lying down and warm.
• Minimize movement until professional medical assistance arrives.
• Always treat injuries as potential shock situations, as symptoms may develop later.

Key Emergency Equipment in the Laboratory

To effectively handle medical emergencies, ensure the laboratory is equipped with the following:

• First Aid Kits: Stocked with bandages, sterile pads, gloves, and antiseptics.
• Safety Showers and Eyewash Stations: Easily accessible for chemical burns and splashes.
• Fire Blankets: For extinguishing clothing fires quickly and safely.
• Safety Goggles and Gloves: Preventive measures to reduce injury risks.
• Emergency Contact Information: Clearly posted numbers for 911 and local emergency responders.

Frequently Asked Questions (FAQs)

1. What should I do if I’m unsure how to help during a medical emergency?

Focus on stabilizing the victim with basic first aid and call 911 immediately. Avoid attempting unfamiliar medical procedures, as improper actions can worsen injuries.

2. Why is it important to report all lab injuries to a supervisor?

Reporting injuries ensures proper documentation, which is crucial for identifying hazards and implementing safety improvements to prevent future incidents.

3. Can I use a fire extinguisher on someone if their clothing is on fire?

No. Fire extinguishers are for objects, not people. Use the stop, drop, and roll method or a fire blanket to extinguish flames on a person’s clothing.

Conclusion: Preparedness Saves Lives

Handling medical emergencies in the laboratory requires a combination of preparedness, knowledge, and quick thinking. Whether dealing with chemical burns, severe bleeding, or stoppage of breathing, the actions you take in those critical moments can make all the difference.

By following proper first aid techniques, utilizing safety equipment like safety showers and eyewash stations, and calling 911 for professional help, you ensure a swift and effective response to emergencies. Remember: Seconds count in a medical emergency, so act decisively and within the scope of your training. Prioritizing lab safety not only protects individuals but also creates a secure environment for all.
