Basic Information
Scope
Scope: This standard mainly consists of scope, normative reference documents, terms and definitions, general principles, requirements for the management of laboratory waste disposal, and classification and disposal methods of laboratory waste. This standard is only applicable to microbiological laboratories. This standard applies to the disposal of laboratory waste in secondary biosafety and lower levels. The content of this standard does not involve laboratory disinfection and sterilization. Main technical content: 6.1 Laboratories shall, in accordance with relevant requirements and the specific circumstances of the laboratory, use different technical methods to remove contamination from all contaminated materials, samples, and cultures before discarding or reusing them. 6.2 Laboratories shall classify waste before disposal. Generally, the waste produced by microbiological laboratories includes the following types: a) General waste; b) Infectious waste; c) Solid waste; d) Molecular biology waste; e) Chemical waste. 6.3 Waste disposal methods 6.3.1 General waste may be placed in black garbage bags or bins and disposed of in accordance with the principles of urban waste management. 6.3.2 Disinfectants, high-pressure sterilization, and incineration should be selected for disinfection and sterilization, and other methods such as dry heat, ultraviolet rays, microwaves, and ionic radiation should not be used. Disposable materials can be high-pressure sterilized and incinerated or directly incinerated. Reusable materials such as Erlenmeyer flasks, Petri dishes, glass pipettes, scissors, forceps, and work clothes should first be soaked and disinfected, then high-pressure sterilized or directly high-pressure sterilized and washed. 6.3.3 Solid waste a) Sharps (such as needles, blades, and sampling gun heads) should be stored in colored (recommended red or yellow) puncture-resistant containers, which should be labeled with biosafety, "sharp ob
