Laboratory standard operating procedures

Main Responsibilities of laboratory

1. The laboratory director is fully responsible for safety. Regularly conduct safety inspections, organize safety inspections, and be responsible for dealing with safety incidents.

2. The experimenter is responsible for the configuration of water, electrical lines, fire-fighting equipment and facility safety inspection.

3. The experimenter is responsible for the management of reagents, medicines, especially toxic and harmful, flammable and explosive substances.

Working procedure of laboratory

1. Safe Operation Specifications

(1) The inspectors must strictly follow the operating procedures in their work, put an end to all illegal operations, stop work immediately when abnormal conditions are found, and register and report in time.

(2) It is forbidden to directly contact the reagent with mouth and nose. The use of volatile, corrosive and toxic substances must be carried out with protective gloves and in a fume hood. Do not leave the post in the middle.

(3) When heating, pressurizing, distilling and other operations, operators are not allowed to leave the site at will. If they have to leave temporarily for some reason, they must entrust others to take care of them or turn off the power.

(4) All kinds of safety facilities are not allowed to be dismantled, moved or used for other purposes, to ensure that they are in good condition and function properly.

(5) Operators should be familiar with the performance and maintenance knowledge of the equipment used, familiar with the common sense and performance of water, electricity, gas, and air pressure cylinders, abide by the rules of safe use, and operate carefully.

2. Management of Toxic and Hazardous Substances

(1) All chemical reagents and medicines that are inflammable and explosive, toxic (especially highly toxic substances), and volatile to produce harmful gases should be classified as dangerous goods, strictly classified, strengthened management, and special personnel are responsible.

(2) Establish detailed accounts, the accounts, objects and cards are consistent, special personnel are limited to purchase, and warehousing inspection.

(3) Dangerous materials, flammable and explosive materials should be stored separately, and toxic materials should be placed in a special locked iron cabinet, and pay attention to ventilation.

(4) Highly toxic items (cyanide, arsenic, etc.) should implement the "double double lock" storage system

(5) The registration and approval procedures should be strictly performed when receiving the product, and the amount of the product should be received as much as possible. It is not advisable to store a large number of dangerous goods and highly toxic reagents in the operating room.

3. Three wastes treatment

(1) The waste liquid produced in the analysis process is mostly corrosive and toxic. This kind of waste liquid directly discharged into the sewer will pollute the environment, so it must be collected uniformly, and then discharged after effective treatment.

(2)After the waste liquid produced in the laboratory is stored to a certain amount, it shall be processed centrally. The waste liquid containers used for recycling should be classified and stored, and mixed storage is prohibited to avoid accidents caused by violent chemical reactions.

(3) Filter paper, weighing paper, cotton wool, etc. with harmful substances should be separated from domestic waste and disposed of separately.

(4) The waste liquid shall be handled by the comprehensive management department and the environmental protection department. All waste liquids (materials) should not be stored for a long time.

(5) Disinfection of bacteria-containing waste liquid after treatment.

4. Security Management

(1) Everyone is responsible for safety work. Personal injury or death accidents should be avoided to ensure the smooth progress of the inspection work.

(2) Regularly check the hidden dangers of safety, prevent the small and the gradual, report the problems in time, and rectify them quickly and seriously.

(3) Equipped with corresponding safety facilities and fire-fighting equipment, and placed it in a place with conspicuous signs, and shall not be moved. The relevant personnel should master the correct use of fire-fighting equipment. The safety officer is responsible for regular inspections and timely replacement of expired and failed fire-fighting equipment.

(4) The circuit shall be checked regularly by the safety officer to prevent the aging and damage of components from causing accidents. When moving and overhauling live equipment, cut off the power supply. Circuit (line) electrical equipment failure should be repaired by special personnel.

(5) The person in charge of each laboratory is responsible for the safety of water, electricity, gas, doors and windows in the room, and the person in charge of each department is responsible for the safety of the department and regularly supervises and inspects.

(6) The substances used in chemical testing shall be kept by special personnel, and the waste liquid shall be kept and disposed of in a centralized manner. Experimenters should have special work clothes and use disposable utensils when operating. It is forbidden to leave the benzopyrene experimental area wearing work clothes and other protective equipment.

(7) The storage of high-pressure gas cylinders such as acetylene gas, argon gas and nitrogen gas shall meet the requirements of relevant regulations.

(8) Those who use the elevator must operate in strict accordance with the procedures specified in the elevator instruction manual, and it is strictly forbidden to bring overweight or oversized objects into the elevator. Pay attention to safety.

(9) In the event of an accident, effective measures should be taken immediately to prevent the situation from expanding, rescue the casualties, protect the scene, and notify relevant personnel to deal with the accident.

(10) Within three days after the accident, the parties shall fill in the accident report form and report it to the person in charge of the research institute. The director presided over an accident analysis meeting in a timely manner, dealt with those directly responsible, and formulated corresponding rectification measures to prevent similar accidents from occurring.

(11) After a major accident occurs, it should be reported to the higher authorities in time, and a special report on accident handling should also be submitted after the event.

5. Experimental record

(1) When entering the laboratory, you must wear protective equipment (white coat and protective glasses). The experimental attitude is rigorous, the operation is standardized, and the experimental order is reasonable. Contact with toxic and harmful reagents, operate with caution, mainly for the personal safety of yourself and others, laboratory and environmental safety.

(2) Requirements for experimental records: the records should be standardized and clear.

(3) First record the temperature and humidity. The text part records the source of raw materials (manufacturer, batch number, specification), the amount of experimental materials (molecular weight, weight (calculated amount and actual amount), volume, moles, batch number), instrument specifications, and thermometer number.

(4) Record the temperature every hour.

(5) Sampling shall be recorded and numbered. The recorder and reviewer should sign and date the back of the record.
