Biomedical wastes are treated onsiteutilizing autoclaves

Autoclaving provides an economical process of killingpathogenic microorganisms through saturation withmoist heat (steam) under pressure

This process makes the microorganisms nonviable bydestroying (denaturing) essential proteins andstructures

Waste Handling Continued

Bags should be left to cool forseveral minutes beforeremoving from autoclave

Once cool, securely closebiohazard bag and place intoopaque black bag which haslarge white trash bin assecondary containment

Quality Control

Methods for Quality Control: Autoclave temperature tape (only tells desired

temperature reached not time or pressure)

Parameter monitoring (pressure, time and temperature)

Record every load on autoclave use log Perform Efficacy monitoring

0 - 100 lbs/month - monthly

100 - 200 lbs/month - biweekly

>200 lbs/month - weekly

Routine parameter monitoring maybe substituted for

biological monitoring for autoclaves which have a

continuous readout and record of operating parameters

(example: autoclave with receipt tape style printout)

Parameter Monitoring

Parameter monitoring is necessaryto ensure efficacy of autoclave

Parameter can be performed byusing Verify integrator strips

Autoclaves that use pinwheel plotsrequire biological monitoring withVerify biological monitoring vialscontaining live GeoBacillus

Stearothermophilus

Autoclave Rooms are BSL-2 Rooms

It is important to rememberthat all autoclave rooms areBSL-2 (biosafety level 2) rooms

Indicates a biohazard is

present such as Hepatitis Bvirus, HIV, the salmonellae,and Toxoplasma spp. Alsoincludes human-derived blood,body fluids, tissues, or primaryhuman cell lines where thepresence of an infectious agentmay be unknown

Indicates that NO FOOD /

DRINKS or cosmeticsareallowed in the room

Typical Door Posting

Personal Protective Equipment

When selecting PPE consider the highest level hazard present,the source of the hazard, and the potential forsimultaneous exposures.

Face protection Goggles or safety glasses with side shields

Clothing Lab coats, scrub suits, gowns (long pants only, no open toed

shoes) Clothing should be replaced immediately when contaminated

Gloves Verify gloves are compatible with your specific application,

process and materials before using Gloves should be replaced immediately if torn Gloves should not be worn outside the lab area Always wear heat resistant gloves and keep your face away

from the door when loading and unloading the autoclave


11/14

Employee Safety Practices

Avoid compressing bags which may create aerosols

Biological waste should be stored in rigid leak proofcontainers such as biohazard boxes, bins, or secondarycontainment pans

Waste should be stored inside the autoclave room andnot in the hallways

Biological waste containing hazardous chemicals

(flammables, chemotherapeutic agents) or Sharpsshould not be autoclaved. Call EH&S at 713-500-5837 for collection of these items

Biological Waste should not be left for someone elseto autoclave


12/14

Good Employee Work Practices

Be a conscientious worker Keep work areas clean and free of hazards

Use Standard Precautions

Treat all human blood and body fluids as ifknown to be infectious

No eating, drinking, or applying cosmetics in the workarea

Frequent hand washing

Decontaminate work surfaces

decontaminate surfaces daily

Common Biomedical Waste AutoclaveDeficiencies

EH&S performs semiannual surveys ofautoclaves utilized for biomedical wastetreatment

Common deficiencies include: Food or drink consumed or stored in

autoclave area Autoclave log incomplete Sterility monitoring not performed Training records incomplete Minors in the work place

In Summary

Autoclave Use Guidelines to follow:

3. Place sterilizing indicator tape on the autoclave bag. Make sure bags

designated for autoclaving are used

2. Place waste inside autoclave. Use secondary containment (pan) under the bag.

If waste does not contain any moisture, put cup of water inside bag for

steam generation

3. Autoclave according to manufacturers instructions for a minimum 30 minutes,

at a minimum operating temperature and pressure of 250 deg. F and 15 psig

4. When cycle is finished, inspect sterilizing tape, and visually check bags to

ensure autoclave was working correctly5. Place waste in black opaque bags. Seal bag with tape or tie wrap

6. Place waste in trash cans labeled Autoclaved Waste Only Log activities in the autoclave usage log Perform routine efficacy monitoring and record results in logbook
