The accident of chemical leakage was heard. If a chemical leak occurs properly and promptly, it can control the seriousness of the consequences and mitigate the destructive accident. If the mistake is handled or handled unproperly, it will not only help to control the situation, but even lead to greater calamity. Therefore, we should pay special attention to the correct handling of chemical leakage by producing and storing units that use a lot of chemicals and other workplaces that need lots or lots of dangerous chemicals.
1. The requirements for the correct treatment of chemical leakage
The workplace should be prescribed treatment chemicals leakage measures, provide cleaning materials and leakage of personal protective equipment required, and store them to allow staff to facilitate the use of the position, and the workers before contact, use or handling of chemicals, and appropriate training, in order to understand the characteristics of chemical hazards, safety tips and emergency measures.
Institutions should have chemical control events. The primary task should be to prevent the occurrence of chemical leakage, which depends, of course, on a set of chemical safety management systems, including safety rules and storage methods. If there is still a chemical leakage accident, the staff concerned will need to implement a safety and appropriate chemical leakage contingency plan to control the development and consequences of the situation.
Two, formulating the contingency plan for chemical leakage treatment
1 the first campaign inspection should be made to identify the types of chemicals, the quantity, the container and the location of the chemicals being used, in order to prepare a list of chemicals. Hazard list should be updated regularly, avoid the list of data differ from the actual situation, and placed in the leakage of chemical / disaster opportunity lowest place to have occurred when the exemption is not available.
2 contact chemical manufacturers / suppliers to collect the material safety data sheet on the list of chemicals (MSDS). The contents of the material safety data sheet will contain procedures for dealing with the leakage of chemical products (small quantities and large quantities of leaks), the implementation of personal protective equipment worn by the cleaners, materials for containment of leaks and sucking agents. These institutions through reference data, compile chemical spill contingency plan, reflect the program processing facilities required and staffing, training, exercises and other matters.
3 provide appropriate and sufficient chemical leakage treatment kits and place appropriate and eye locations for convenience. Check regularly to make sure that they are in good performance to spare. The leak processing suite can generally include:
Personal protective equipment, such as protective clothing, protective gloves, goggles or face masks and appropriate respirators;
Containment leakage of material, such as sand or other inert materials;
Blister chemical leakage material, such as sand or other blister agent;
Warning marker enclosure;
A suitable container for carrying waste.
A reagent needed to purify the procedure.
4 arrange appropriate training for the staff to understand the hazard characteristics of chemicals, emergency measures, and the proper use of the leak treatment kit.
5 a chemical leak exercise is conducted on a regular basis and an assessment is made to ensure the effectiveness of the procedure.
6, check regularly whether there is a gap between the actual stock of chemicals and the stock of recorded species. If we find that chemicals are missing, we should thoroughly investigate that chemicals are actually stored in other inappropriate locations, causing harm. Last year, a tin laboratory has leak "; picric acid police and firefighters arrived at after receiving the report, the chemicals stored in principle a rusty steel container, the container has been screened out of the past for a long time.
7, the chemical leakage treatment contingency plan needs to be documented and regularly reviewed. The chemical leakage procedures should make sheets and notices, send them to the appropriate staff and post them in an appropriate place, which can play a reminder role and facilitate their inspection.
Three. Treatment procedures for chemical leakage
1 evacuate the staff of the leakage site quickly and restrict any person into the leakage area.
2 in the safety case confirmed the leak is that chemicals will leak accident report to the supervisor and response personnel event notification by trained; such as personnel training institutions without strain, and encounter a lot of leakage, fire or medical auxiliary, please call 999 emergency hotline;
3 if you failed to confirm the handler and then take the service you cut adventure trying to clean up the leaking chemicals, should leave the scene immediately;
4 wear personal protective equipment and strengthen the protection of individual.
5 the ventilating area is well ventilated.
6 out of all the fuel source and the leakage of incompatible substances;
7 staff who take care of the contaminated chemicals. Immediately take off the splash of chemicals, such as the spatter of the skin chemicals, and at least fifteen minutes with the use of clean water.
8, we should use Containment Materials in the leak handling kit to prevent the leakage from spreading, prevent leakage from entering the drainage channel or other ways to release chemicals to the outside world, and use the absorption agent or neutralizer to clean up the leakage chemicals.
9 the leaking chemicals treated by the mirror are placed in the appropriate container and cover seal and affixed to the appropriate warning label. Please keep in mind: after the use of the absorption agent, the related leakage chemicals will not change their chemical properties, so it is necessary to treat them carefully.
10 the chemical waste must be discarded in accordance with the relevant legislation. Before the recycling of chemical waste, containers should be placed in the smoke kitchen or other properly ventilated areas.
11 record the details of the leakage accident in order to analyze the cause of the accident and make improvement measures to avoid the occurrence of the accident.
