Fire Blanket

These are used to put out smaller fires before

they have a chance to become large fires

Steps for effectively using a fire blanket

• Identify a Small Fire: Recognize when a fire is manageable and can be addressed with a fire blanket.

• Access the Fire Blanket: Open the bottom of the container to get the fire blanket.

• Wrap the Blanket: Carefully wrap the blanket around the object on fire or around the person whose clothes are burning.

• Cut-Off Oxygen Supply: Ensure the blanket fully covers the flames to suffocate the fire by cutting off its oxygen supply.

• Monitor the Situation: After using the fire blanket, stay alert for any resurgence of flames and seek assistance if needed.

Fire Exit

Emergency Exit Guide

Follow Evacuation Signs: Evacuate the building immediately and use illuminated signs to guide your way.

Do Not Use Elevators: Always take stairs during a fire evacuation.

Gather at Assembly Point: Meet at the designated safe area. Do not re-enter the building until the Campus Fire Marshal gives the “all-clear” signal.

First Aid for minor cuts and burns

• Minor cuts and scrapes from broken glass or minor burns from chemicals or heat need to be treated, no matter how small they seem.

 

• Wash the area with plenty of water and tell your instructor

• To help prevent injuries from broken glass, always use the broom and dust pan to clean up broken glass.

• Dispose of any glass in the glass garbage.

First Aid for eyes

Eye wash fountains are used to wash the eye if a chemical or other object gets into the eye. Delaying treatment may cause permanent damage to the eye. You may need to ask another person to help you to the fountain. 

Steps to operate an Eyewash Station

Follow these steps to use the eye wash fountain:

1. Push the lever to make the water flow.

2. Flush your eyes for at least 15 minutes.

3. Keep your eyes open and rotate your eyeballs in all directions.

4. Seek medical attention immediately.

First Aid for Chemical Spills on a Person

Safety showers are essential for emergencies involving large chemical spills on a person or if clothing catches fire. Immediate action is important, as delays can result in severe skin damage. If needed, request assistance from someone to help you reach the shower.

Steps to operate a Safety Shower

1. Pull the Lever: Activate the shower by pulling the lever to start the water flow.

2. Flush Your Body: Rinse your body thoroughly for at least 15 minutes.

3. Remove Affected Items: Take off any clothing, jewelry, and shoes that have come into contact with the chemical. All students should exit the lab, and someone of the same gender will assist you while the curtains are closed for privacy.

4. Seek Medical Attention: Get medical help immediately after using the shower.
