Autoclaves are indispensable in the laboratory for sterilising equipment and materials, but they must be used correctly to ensure safety. Improper use can lead to accidents, including burns, exposure to harmful agents, and equipment damage. Here are the top five safety tips to remember when operating an autoclave.
1. Wear Proper Protective Equipment (PPE)
Always wear appropriate safety gear when loading, operating, and unloading an autoclave. This includes heat-resistant gloves, lab coats, and face protection to shield against steam burns and hot surfaces.
2. Check the Chamber and Door Seal
Before each use, inspect the autoclave chamber and door seal for any signs of wear or damage. A compromised seal can lead to steam leaks, reducing effectiveness and posing a burn hazard.
3. Do Not Overload the Autoclave
Ensure that the autoclave is not overloaded and that there is enough space around items for steam circulation. Overloading can lead to incomplete sterilisation and increased pressure, risking container breakage.
4. Use Proper Containers and Packaging
Use only containers and packaging materials that are rated for autoclave use. Materials not designed to withstand high temperatures and pressures may melt or explode, causing contamination and injury.
5. Allow Items to Cool
After the sterilisation cycle, allow the autoclave and its contents to cool down before handling. Opening the door too soon can result in a rapid release of steam, posing a burn risk. Items should be cool enough to handle with bare hands before removal.
Following these safety tips can significantly reduce the risk of accidents and injuries associated with autoclave use. Always refer to the manufacturer’s guidelines for specific operating procedures and maintenance recommendations.
