  3. Report the incident: Inform your supervisor or authority figure of the incident immediately to ensure the appropriate measures are taken.

It’s crucial to know the location of fire extinguishers and emergency exits to prevent or minimize damage during such times.

According to OSHA, welding sparks are a common cause of fire accidents in welding workshops.

Emergency equipment: because running around the workshop screaming ‘where’s the fire extinguisher?!’ is not a safety protocol.

Know where emergency equipment is located

In an emergency, it’s key to know where the important gear is. Having it easy to find can be a lifesaver! Keep these points in mind:

  1. Have a plan. Knowing the places of the first aid kit, fire extinguisher, and other safety equipment will help you act quickly.
  2. Make sure it’s accessible. Everyone should know how to get the emergency stuff. And it should be unblocked all the time.
  3. Inspect often. Check that the equipment is working, placed right, and well-maintained.

Note: Depending on the industry and location, the equipment’s location may differ. When you’re not sure, get specialized help.

Fun fact: A National Safety Council study shows that if AEDs (Automated External Defibrillators) are used within three minutes of cardiac arrest, survival rates go up from 6% to 74%.

Have a designated person responsible for calling emergency services

Assign a person to take charge in emergency cases! They must be trained, so they can handle the situation. Here’s a guide:

  1. Choose someone who can decide if it’s an emergency.
  2. Inform them what to communicate to emergency services: location, type of emergency, any injuries.
  3. Share the list of available emergency numbers with them.
  4. Ensure they know the layout of your facility to help first responders get there quickly.

The assigned person should stay calm and use simple language. Don’t let jargon confuse them. Crazy-Fact: In a FEMA report, 60% of American firms never recover from disasters.

Know basic first aid and CPR

Having basic knowledge of emergency medical procedures can save lives! Knowing what to do before help arrives is key in an accident or injury. Here’s a 4-step guide on how to administer basic first aid and CPR:

  1. Evaluate the situation and check for any dangers.
  2. Call emergency services right away.
  3. Give basic first aid – stop bleeding, stabilize injuries, keep airways and breathing open.
  4. If needed, do CPR until trained staff arrive.

It’s essential to take a course in basic first aid and CPR to be as accurate as possible during an emergent situation. Not having the right actions when serious injuries occur can lead to severe consequences, even after calling for help. Also, some heart attack victims have no warning signs, which is why knowing how to do CPR is so important to save their life.

Evacuate the work area if necessary

In an emergency, it’s important to vacate the area right away. Personnel should leave calmly, but be alert for potential problems. Follow the evacuation procedures and exit routes. Activate alarms, if needed. Contact emergency services.

Meet at a safe point, outside of the affected area.

Leaving without hesitation can save lives, so be prepared to leave belongings behind. Review and practice evacuation procedures regularly, so everyone knows their role in an emergency. Failing to prepare could mean injury or death. Stay informed and prioritize safety.
