Safety Equipment / Lab Safety Video Part 2

Summary

This video script emphasizes the importance of laboratory safety, outlining essential safety equipment such as safety showers, eyewash stations, fire extinguishers, and fire blankets. It highlights proper usage and maintenance of these tools to minimize the risk of accidents. The script explains the different types of fires and their corresponding extinguishing methods and stresses the need for regular safety checks. Additionally, the video emphasizes the importance of knowing evacuation routes and understanding lab safety behaviors to protect oneself and others in the event of an emergency.

Takeaways

• 😀 Accidents are inevitable in a laboratory, but knowledge of safety measures can minimize the risks.
• 😀 Always identify the location of safety equipment when working in a lab for the first time.
• 😀 Every lab must have a safety shower and eyewash station, both of which should be tested weekly.
• 😀 In case of chemical or flame exposure, immediately move to the safety shower and remove any saturated clothing.
• 😀 If exposed to hazardous chemicals in the eyes, use the eyewash station and rinse for at least 10 minutes.
• 😀 There are four types of fires: Class A (ordinary combustibles), Class B (flammable liquids), Class C (electrical equipment), and Class D (combustible metals).
• 😀 Water should never be used to extinguish Class B or C fires as it can worsen the situation or cause electrocution.
• 😀 Dry chemical fire extinguishers are effective against Class A, B, and C fires and are often installed near exits.
• 😀 In case of a large fire, evacuate all personnel immediately and call 911.
• 😀 A fire blanket should be used to extinguish small fires or to help a person whose clothing is on fire, but never wrap a standing person.
• 😀 Each lab should have a first aid kit, and evacuation routes should be clearly posted and known by all personnel.

Q & A

What is the importance of lab safety equipment?

Lab safety equipment helps minimize the likelihood of accidents and can save lives when an accident occurs. Familiarizing yourself with the location and proper use of this equipment is crucial in maintaining safety.

What are the key safety equipment items every lab should have?

Every lab must have a safety shower, eyewash station, fire extinguisher, fire blanket, first aid kit, evacuation routes, and a chemical fume hood.

How often should safety showers and eyewash stations be tested?

Safety showers and eyewash stations should be tested weekly to ensure they are working properly and that the water is clean.

What should you do if your clothes or skin are exposed to a chemical or flame?

If exposed to chemicals or flames, immediately move to the nearest safety shower, remove saturated clothing, and thoroughly rinse the affected area. If exposed to flames, drench your entire body, and call 9-1-1.

What is the correct procedure for using an eyewash station?

If your eyes are exposed to hazardous chemicals, hold your eyes open and rinse them thoroughly for at least 10 minutes using the eyewash station.

What types of fires exist in a lab, and how should each be handled?

There are four types of fires in the lab: Class A (ordinary combustibles like wood or paper), Class B (flammable liquids and solvents), Class C (electrical equipment), and Class D (combustible metals). Class A fires can be extinguished with water or general purpose extinguishers, while Class B and C fires require chemical foam extinguishers. Class D fires typically require dry chemical extinguishers.

What should you do if a fire is too large for you to control?

If a fire is too large, immediately evacuate all personnel and call 911. Do not attempt to use a fire extinguisher unless you are trained.

What is the proper way to use a fire blanket?

To use a fire blanket, help the person to the floor, wrap the blanket around them, and assist them in rolling until the fire is extinguished. Never wrap a person while they’re standing as it can force flames upward.

What items should be in a lab's first aid kit?

A lab's first aid kit should contain bandages and antiseptic for treating minor injuries.

How should a chemical fume hood be used to ensure safety?

When using a chemical fume hood, ensure the exhaust fan is on, check the hood is venting properly, and adjust the sash to either 8 or 16 inches for most applications. Never store chemicals under the hood, and always clean up materials after use.
