Fire prevention of the hottest Organic Chemistry L

Fire prevention in organic chemistry laboratory

in laboratory work, due to the complexity of materials and experimental conditions and the occurrence of unpredictable problems, fire and explosion accidents often occur, resulting in irreparable losses in scientific research. Therefore, doing a good job in laboratory fire prevention is one of the basic guarantee work of scientific research. In all kinds of laboratories, especially the organic chemistry laboratory, there are a large number of flammable and explosive chemicals, many unsafe factors and the greatest fire risk. Therefore, the organic chemistry laboratory should be the focus of the laboratory fire prevention work

I. fire risk of organic chemistry laboratory

the high fire risk of organic chemistry laboratory is determined by many factors

in the organic chemistry laboratory, various inflammable and explosive chemicals are widely used. Some of them are flammable, some are spontaneous combustion, and some conflict with each other. A little carelessness is likely to lead to fire accidents; The organic chemistry laboratory uses a large number of various electrical equipment, and in some cases there are open fire operations, which increases the fire risk of the laboratory; Distillation, reflux, extraction, electrolysis and other typical operations often carried out in organic chemistry laboratories are characterized by high fire risk

the safety quality of the personnel engaged in laboratory work is also uneven, and they do not pay enough attention to the fire safety in the experiment, especially the laboratory staff who have not received fire training, lack proper understanding of the fire safety work, have a weak awareness of fire safety, and do not operate according to the operating procedures. In addition, they do not master the experimental essentials, are not skilled in operation, or misoperate, making it impossible to prevent fire

in addition, many organic chemistry laboratories are old, the building structure and layout are unreasonable, and the equipment used is aging or there are defects in safety precautions, which are also important factors for their frequent fire

II. Fire prevention measures for organic chemistry laboratory

1. Strengthen fire safety education for laboratory personnel. Carry out detailed pre job fire safety education for the laboratory personnel, so that they can not only master the basic safety, the main intention is to understand the ideas and relevant policies of Jilin Province for the development of biodegradable materials and products industry, the full operating procedures and fire prevention knowledge, but also understand the national fire protection laws and regulations and various rules and regulations to restrict their behavior, but also master the basic fire-fighting methods and self-help knowledge in case of fire

2. Strengthen the management of inflammable and explosive chemicals

most of the materials used in the organic chemistry laboratory are inflammable and explosive, which are easy to cause fire and explosion accidents due to their lively nature and poor stability. Therefore, strengthening the fire control management of its storage and cutting off the material source of fire are the key points of fire prevention in organic chemistry laboratory

firstly, the stock of various items in the laboratory should be strictly limited. In general, when the total amount of a small amount of flammable and explosive chemicals remaining or commonly used in the laboratory is not more than 5kg, the 204 flat open aluminum alloy window handle should be placed in the metal cabinet and kept by a specially assigned person. When it is more than 5kg, it should be returned to the dangerous goods warehouse in time for storage. It is strictly prohibited to use the laboratory as a warehouse

secondly, the storage of inflammables and explosives should be strictly managed. The principle of classified and itemized storage shall be strictly implemented to prevent the occurrence of running, emitting, dripping and leakage. Articles used or made in the laboratory must be strictly sealed and stored to prevent accidents caused by volatilization or deterioration; Any article must be labeled immediately after it is placed in the container. In case of any abnormality, it shall be checked and verified in time. It is not allowed to throw it around or use it blindly; It is forbidden to store low flash point liquids in the refrigerator, and other flammable liquids should also be completely closed to prevent liquid volatilization from causing explosion accidents in case of refrigerator opening and closing sparks; The location where dangerous goods are stored shall be protected from sunlight, and the opening parts such as sunny windows shall be provided with sunshade facilities; All kinds of gas cylinders used in the laboratory (such as hydrogen from scratch) shall be stored in a special warehouse and supplied by pipes. The cylinder warehouse shall be provided with good ventilation, cooling, explosion-proof, anti-static and other fire safety measures. This year's government work report repeatedly mentioned that laboratories in private enterprises and private economies that use a large amount of combustible gas should set up combustible gas leak detection and alarm devices according to regulations
