Description

Temporary storage device for dangerous solid waste for high-grade biological safety laboratory

Technical Field

The invention belongs to the technical field of biological waste storage devices, and particularly relates to a temporary storage device for dangerous solid waste for a high-grade biological safety laboratory.

Background

The biological safety laboratory is divided into a first-Level (BSL-1), a second-Level (BSL-2), a third-Level (BSL-3) and a fourth-Level (BSL-4) according to the biological safety protection Level of the laboratory; ABSL-1, ABSL-2, ABSL-3 and ABSL-4 respectively represent the biosafety level of laboratories engaged in live animal operations. The high-grade Biosafety laboratory refers to a laboratory with three-grade and four-grade Biosafety protection grades, and is used for developing scientific research on high-pathogenic microorganisms with 3-grade and 4-grade risks (recognized as first-class and second-class pathogenic microorganisms domestically) internationally [ World Health organization.laboratory Biosafety Manual [ M ]3rd edition. geneva,2004 ]. The high-grade biological safety laboratory is required to meet the GB19489-2008 laboratory biological safety general requirements and the GB50346-2011 biological safety laboratory building technical specifications in terms of hardware construction, the possibility that high-risk pathogens are diffused to an external environment along with human flow, logistics, water flow and air flow is strictly controlled by physical protection facilities and equipment, and the personnel infection incidence and the environmental pollution incidence are reduced to zero.

In order to ensure the safety of workers in the biological safety laboratory, personnel outside the laboratory and the surrounding environment, the high-grade biological safety laboratory is mainly realized by the protection of a primary barrier and a secondary barrier. The primary barrier is the isolation between the experimental operator and the operated object (pathogen, infectious material and infected animal), plays a main barrier role, protects the experimental operator, and is realized through safety equipment. The secondary barrier is a peripheral facility of the primary barrier, and can ensure that operating personnel are prevented from being infected by operating pathogens and prevent the pathogens from leaking into the environment when the primary barrier fails or accidents occur outside the primary barrier, so that the isolation between the laboratory and the external environment is realized, and the secondary barrier comprises a building structure, decoration, ventilation and purification, water supply and drainage, a temporary waste storage device, a sterilization system and the like. However, in the current temporary storage device for dangerous solid waste for high-grade biosafety laboratory, when the waste is stored, the waste is mostly stored by one person and taken out, and when the waste is operated by one person, the risk of pathogen leakage caused by incorrect storage or taking out exists.
