1) Expired experimental drugs, chemical reagents;
2) Experimental waste liquid and waste gas;
3) Direct packaging containers (eg reagent bottles) containing hazardous waste;
4) Filter paper, coated paper, cotton paper, waste activated carbon and plastic containers with harmful substances;
Scientific collection of hazardous waste should be carried out, safely stored, disposed of in accordance with national regulations, and must not be discarded or placed indiscriminately!
The temporary storage and storage of hazardous waste shall be the responsibility of the designated person in each production waste unit. . .
It is necessary to establish a hazardous waste job management system, make records and statistics, and find problems in a timely manner!
All production and abatement units must comply with the following regulations
1. Each laboratory must set up hazardous waste storage cabinets (boxes, racks) and have obvious warning signs. The storage location is indoors, to be safe and secure, away from fire and water sources.
2. Containers containing direct hazardous waste must meet the following requirements:
(1) The material of the container must be compatible with hazardous waste (not reacting with each other);
(2) The container should meet the corresponding strength and protection requirements;
(3) The container must be intact and tightly sealed to prevent leakage and spillage during handling and transportation;
(4) Each container containing hazardous waste must be affixed with an obvious label (or original, or a new label indicating the Chinese name and dangerous nature of the substance in question). The label must not be altered. trace;
(5) All containers containing liquid hazardous waste must have a proper amount of space and cannot be filled too full;
3. Temporary storage of hazardous waste must be done:
(1) Separate by class, incompatible materials should be stored separately to prevent danger;
(2) Fragile packaging materials and direct packaging materials with a container capacity of less than 2L shall be fixed in wooden boxes or solid cardboard boxes according to their properties, and filled with fillers to prevent collision and extrusion to ensure safe storage;
(3) Containers containing direct hazardous waste should be prevented from tilting, inverting and stacking during storage (including in indirect packaging);
(4) The storage time of hazardous waste in each laboratory should not exceed 6 months, and the stock should not be excessive;
Hazardous waste disposal
Work program
1. The classified wastes collected by each unit shall be classified and counted;
2. Classification of hazardous wastes shall be delivered to the designated place in batches and delivered to the relevant units approved by the state for safe disposal;
3. When each unit delivers hazardous waste, it must be inspected again, whether the container and secondary packaging directly meet the requirements of these regulations, and the problems are promptly rectified;
Collection of hazardous waste
1. Anyone who purchases chemicals, reagents, etc. is responsible for managing the above items. Always check the quality and label of the above items to prevent the labels from falling off and the items from deteriorating, making it difficult to use or dispose of.
2. Hazardous waste generated by each laboratory shall be collected at any time to be collected in a container filled with the requirements and stored in the hazardous waste storage cabinet of the room at the same time. During the collection process, special attention shall be paid:
(1) Incompatible substances (ie, substances that react with each other) should be contained in separate containers;
(2) In order to ensure safety and prevent possible dangers during collection or disposal, when collecting hazardous waste, ensure that the contents of the label on the container are consistent with the contents of the contents. Do not arbitrarily change the label. Labels with altered marks are considered as Invalid label.
(3) Unstable substances should be pretreated and collected and stored.
3. For the hazardous waste generated by the ability to dispose of itself, it is necessary to report the disposal plan and treatment volume to the “Green School†office for record.
How to safely process expired experimental reagents?
1. The waste liquid of the combustible substance is placed in a combustion furnace for combustion. If a small number, can be made to place it into an iron or porcelain container for outdoor secure it to burn. When igniting, take a long stick and put a rag on the end of the oil, or use wood chips and other things, and stand in the upwind direction to ignite and burn. Also, it must be monitored until it is burned out.
2. For substances that are difficult to burn, mix them with flammable substances or burn them into an incinerator equipped with a combustion burner. For substances that are difficult to burn, such as polychlorinated biphenyls, some substances that have not been incinerated are often discharged. For high-concentration organic waste liquids containing water, this method can also be incinerated.
3. Waste liquids that generate harmful gases such as NO2, SO2 or HCl due to combustion must be burned in an incinerator equipped with a scrubber. At this time, it is necessary to wash the combustion exhaust gas with an alkali solution to remove harmful gases therein.
4. The solid material may also be dissolved in a flammable solvent and then burned.
