Waste Treatment
Autoclave
A device that uses steam under pressure to sterilize medical waste and instruments. Autoclaving is one of the most common treatment methods for regulated medical waste.
Definition
A device that uses steam under pressure to sterilize medical waste and instruments. Autoclaving is one of the most common treatment methods for regulated medical waste.
What This Means for Your Facility
Autoclaving subjects waste to saturated steam at 121°C (250°F) under 15 psi of pressure for a minimum of 30 to 60 minutes, depending on load size and waste density. This process destroys vegetative bacteria, viruses, fungi, and most bacterial spores. Under California's Medical Waste Management Act (HSC §118215), autoclaving is an approved treatment method for biohazardous waste, but not for pathological waste, which must be incinerated.
Healthcare facilities that operate on-site autoclaves take on the regulatory status of a medical waste treatment facility and must register with their Local Enforcement Agency (LEA). This brings additional requirements: routine spore testing (typically weekly using Geobacillus stearothermophilus biological indicators), temperature and pressure log documentation, and annual operational reviews. Facilities that skip spore testing or fail to maintain calibration records risk having their treatment permit revoked.
Most BayArea Compliance clients rely on our permitted treatment network rather than operating their own autoclaves. We handle pickup, manifesting, transport, and treatment through certified facilities, eliminating the compliance burden of on-site treatment. For clients who do maintain autoclaves for instrument sterilization, our COMPLIANCE|360 program includes guidance on spore testing schedules and documentation requirements.
