Autoclave Machine Safety Guidelines

Autoclave Machine Safety Guidelines

An autoclave is a machine that combines pressure and temperature to sterilize reusable medical equipment. All reusable items must be fixed before being used in a clinical setting. The steam sterilization process is an effective method of killing microorganisms. However, it can be dangerous if not carried out correctly. It involves removing all air from the chamber and replacing it with steam.


The temperature of a lab autoclave machine plays a vital role in sterilization. It can affect the time it takes certain microorganisms to die off and help determine how long the materials will hold their temperature within the autoclave chamber. Steam-based sterilization cycles use saturated steam and specific pressure to achieve 121deg C (250 deg F). These temperatures kill various microorganisms, which is why they are commonly used in healthcare settings. Some autoclaves use a pre-vacuum to remove moist air from the chamber before steam is admitted. This allows the moisture to penetrate even the most minor holes and pores in porous objects. Wear proper PPE, including heat-insulating gloves, a lab coat, and closed-toe shoes when using a lab autoclave. This helps to prevent burns and scalds from the heat and steam. Additionally, do not open the door while a cycle is in progress. This can cause the door to blow off, resulting in a scalding injury to your hands or arms.


The pressure of the steam that enters an autoclave nail salon machine helps to keep it at a consistent temperature. This is important because it ensures the sterilization process is efficient and effective. For this reason, it is essential to check the machine’s pressure regularly and maintain a constant level. Modern machines have the equipment to help with this task and digital and mechanical monitoring systems. During the heating phase, the steam displaces all the air in the chamber, increasing the pressure and temperature. After this, the cycle transitions to the exposure (sterilization) phase, where items are exposed to steam at a set temperature for a fixed amount of time. Once the sterilization is complete, the exhaust valve is opened, and the pressure is released. This will allow the chamber to return to its normal atmospheric pressure, and the goods can be removed. This is also called the excellent down phase and may include drying time.

Cycle Time

Steam sterilization, also known as autoclaving, is a process that kills microorganisms and spores using a combination of steam, pressure, and time. It decontaminates specific medical waste and sterilizes instruments, media, and labware. The cycle time of an autoclave machine is a crucial factor in sterilization. It affects how long each piece of equipment is exposed to the steam and whether or not it will reach the required temperature and pressure set point within the chamber. Depending on the type of equipment being sterilized, various cycles can be used to achieve the desired results. These include primary gravity cycles, high-speed pre-vacuum cycles, and dynamic air removal cycles. In a high-speed pre-vacuum process, the air is removed from the chamber before the steam is introduced. This eliminates the air entrapment problem in a gravity displacement cycle.


A safe autoclave machine operation is critical to the safety of personnel and those close to it. To ensure this, laboratory supervisors must provide training to use these machines safely. This involves understanding and following the proper loading, unloading, and handling procedures that must be followed to avoid burns or other injuries. In addition, the operator must wear personal protective equipment and a rubber apron or face shield when removing liquids from the autoclave. In addition to this, items that contain biohazards, such as sharps and waste, must be decontaminated before being sterilized in an autoclave. This prevents contamination by infectious microbes that can cause illness and bacterial or viral infections.
