Influence of packaging and processing conditions on the decontamination of laboratory biomedical waste by steam sterilization.
The conditions for optimal steam decontamination of polypropylene bags half loaded with laboratory biomedical waste were studied (276 bags were processed).
Controls were single-closed bags without water added or incisions made in the top, standing freely in an autoclave set at 121oC.
The average time required to reach 121oC at the load center was 46 min for controls.
A significant increase in this time occurred following addition of water to bags without incisions (60 min), with double bagging (60 min), or when using vertical confiners (82 min).
A significant decrease occurred when bags were slashed (37 min) or processed at 123oC (32 min) or 132oC (19 min).
Horizontal containers or addition of water to slashedbags had no significant effect.
