Autoclave Safety and Operation

This video tutorial, a collaboration between the National Biosafety and Biocontainment Training Program, the National Institutes of Health, and Dartmouth College, provides comprehensive guidance on autoclave safety. It covers the importance of wearing personal protective equipment, understanding autoclave components, and following proper procedures for decontaminating biohazardous waste. The tutorial emphasizes the need for safety precautions to prevent injuries, such as burns from steam and superheated liquids. It also highlights the importance of consulting safety professionals and adhering to regulations for medical waste disposal.

What is the primary purpose of wearing a liquid-resistant apron when using an autoclave?

• To avoid liquid contamination

• To enhance comfort

• To prevent heat exposure

• To protect against chemical spills

Which component of the autoclave is responsible for maintaining a constant pressure during operation?

• Steam inlet

• Jacket pressure gauge

• Drain

• Chamber pressure gauge

What is the minimum temperature and time required to decontaminate biohazardous waste in an autoclave?

• 100 degrees Celsius for 30 minutes

• 110 degrees Celsius for 2 hours

• 121 degrees Celsius for 1 hour

• 150 degrees Celsius for 45 minutes

Why should the bag containing biohazardous waste be loosely packed before autoclaving?

• To allow steam to penetrate

• To ensure even weight distribution

• To prevent the bag from melting

• To reduce the risk of chemical reactions

What should you check before opening the autoclave at the end of the cycle?

• The steam has completely evaporated

• The temperature is still high

• The chamber pressure has returned to zero

• The door is cool to touch

What is a potential risk when opening an autoclave with superheated liquids inside?

• The liquids may freeze

• The liquids may boil over violently

• The liquids may evaporate instantly

• The liquids may solidify

What is a common cause of burns when using an autoclave?

• Using incorrect settings

• Condensation splashing

• Inhaling steam

• Touching the cold surfaces

Why is it important to stand back when opening the autoclave door?

• To check for leaks

• To avoid inhaling fumes

• To allow the door to cool

• To prevent steam burns

What should you do if you notice steam escaping from the autoclave?

• Ignore it as it is normal

• Use caution to avoid burns

• Open the door immediately

• Increase the pressure

What is a potential hazard of touching the sides of a hot autoclave?

• Electrical shock

• Chemical exposure

• Radiation exposure

• Burns
