Laboratory Safety and Equipment Maintenance

What are some common lab safety rules?

• Wearing appropriate protective clothing, following proper handling and disposal procedures for chemicals, using equipment correctly and safely, and knowing the location of safety equipment.

• Not wearing any protective clothing

• Ignoring handling and disposal procedures for chemicals

• Using equipment incorrectly and unsafely

Why is it important to follow chemical handling procedures in the laboratory?

• To ensure safety and prevent accidents or exposure to hazardous substances.

• To save time and increase efficiency in the laboratory.

• To impress the supervisor and get a promotion.

• To make the laboratory look organized and clean.

What are some examples of protective equipment used in a laboratory?

• safety shoes, earplugs, and hard hats

• gloves, goggles, lab coats, and face masks

• aprons, boots, and helmets

• safety glasses, gloves, and respirators

What should you do in case of a chemical spill or accident in the lab?

• Notify your supervisor or the designated authority, evacuate if necessary, follow emergency procedures, avoid direct contact, and use appropriate PPE.

• Wait for someone else to handle the spill

• Clean up the spill by yourself

• Ignore the spill and continue working

Why is equipment calibration important in a laboratory?

• To waste time and resources.
• To increase the chances of errors in experiments.
• To make measurements less accurate.
• To ensure accurate and reliable measurements.

What are the steps involved in calibrating a laboratory instrument?

• The steps involved in calibrating a laboratory instrument are: 1. Prepare the instrument for calibration. 2. Gather the necessary calibration standards and reference materials. 3. Follow the manufacturer's instructions for calibration. 4. Perform the calibration by comparing the instrument's readings to the known values of the calibration standards. 5. Record the calibration results and any adjustments made. 6. Validate the calibration. 7. Repeat the calibration process periodically.

• 1. Shake the instrument vigorously. 2. Use random calibration standards. 3. Skip the validation step.

What are some emergency response protocols that should be followed in a laboratory?

• Wear casual clothing in the laboratory, as it is more comfortable during emergencies.

• Familiarize oneself with emergency exits and equipment, know how to use safety equipment, understand emergency reporting procedures, know the location of emergency showers and eyewash stations, and be aware of specific hazards and safety protocols.

• Do not report emergencies to the appropriate authorities, as it may cause unnecessary panic.

• Ignore emergency exits and equipment, as they are rarely used.

Why is it important to wear protective eyewear in the lab?

• To prevent hair from falling into the eyes.

• To block out the bright lights.

• To look cool and professional.

• To protect the eyes from potential hazards.

What are some common chemical handling procedures in a laboratory?

• Wearing PPE, using proper ventilation, following storage and disposal procedures, conducting experiments in a fume hood or designated area

• Not wearing any protective gear, working in a closed room with no ventilation, disposing chemicals in regular trash bins

• Storing chemicals in open containers, conducting experiments on an open bench, not following any disposal procedures

• Using improper ventilation, not wearing any protective gear, storing chemicals in an unorganized manner

How often should equipment maintenance be performed in a laboratory?

• Regularly

• Every 10 years

• Never

• Once a year
