Analysis of the accident involving the burns of Xiao XX, a laboratory technician from the quality inspection department of a chemical company 1. The course of the accident: At about 9 a.m. on April 10, 2009, Xiao XX, a laboratory technician from the Quality Control Department, was riding a bicycle to the crude benzene section of the chemical industry to take a sulfuric acid sample. When he rode to the west corner of the old metering tank, the sampling bottle and the binding wire broke off, and the sulfuric acid bottle fell to the ground and exploded. , the liquid splashed on Xiao Jing's face, neck and feet. She hurried to the water pipe and washed it with plenty of water. She found 4 minor burns on her face and 5 on her neck, and her work clothes and rubber shoes were burned. Later, her lover drove her to the No. 7 Provincial Hospital for treatment. 2. Cause analysis: 1. Because Xiao XX did not check the sampling tools properly before taking samples, and the corrosion of the iron wires tied to the sampling bottle bolts was not discovered in time, so he went to take samples and broke due to force during the process. The sulfuric acid bottle fell to the ground and exploded, causing the accident. This is a major reason. 2. The iron wire that tied the mouth of the glass bottle had been corroded before sampling. Xiao XX was riding a bicycle, holding the handle with one hand and carrying the bottle with the other, causing shaking on the road, which further accelerated the probability of the wire breaking. When we rode to the west corner of the old metering tank in the thick benzene section, there happened to be a liquid discharge pipe on the ground here. The wheels went over some bumps, and the wire at the corroded area of ​​the bottle mouth was twisted off, causing the sulfuric acid bottle to fall, and Xiao XX was burned by the splashed sulfuric acid. This is also a direct reason. 3. Since the laboratory technicians were not equipped with personal acid-proof suits, taking sulfuric acid samples posed a threat to them. This time the sulfuric acid bottle fell to the ground and splashed, burning Xiao Jing's work clothes, rubber shoes, face and neck, which was also an objective reason. 4. Day shift monitors, section leaders, and department safety officers and managers are responsible for ensuring that employees are fully equipped with acid-proof clothing and whether they actually wear it. When riding a bicycle for a long time, one hand holds the handle and the other hand extracts sample bottles, etc. * Problems such as the hidden dangers of inertial operation are ignored. This is also an indirect reason. 3. Responsibility analysis: 1. Operator Xiao XX did not carefully check and confirm the iron wire tied to the mouth of the sampling bottle before taking samples. This is a violation of the * Inertial operation. Since I was riding a bicycle with one hand holding the handle and the other hand taking out the sample bottle, I had a sense of luck, which caused my body to be bumped by the road, causing the wire to break, and being burned by the splashed sulfuric acid. I should bear direct responsibility. 2. The monitor, Zhang XX, was directly in charge of the laboratory work during the day shift. He did not ask or resolve whether the acid-proof clothing distributed to employees was fully in place and worn. As a result, the sampling employees did not wear acid-proof clothing for a long time, took samples by bicycle, and did not check the equipment used for sampling. This caused problems for employees. * Failure to educate, manage and stop the hidden dangers of inertia eventually led to this accident. Therefore, squad leader Zhang XX should assume certain management responsibilities. 3. Duan Chang Li XX was in charge of the laboratory work, and he was also a part-time safety officer who did not educate the laboratory technicians enough and failed to check the sampling tools properly, which caused Xiao Jing to corrode and break the wire when taking samples, and she was burned by the sulfuric acid splashed by the explosion in the bottle. Therefore, Li XX should bear certain management responsibilities. 4. Wang xx, manager of the quality inspection department, has not implemented acid-proof clothing and gloves for employees. The employees have been riding bicycles for a long time and taking samples without wearing acid-proof clothing, turning a blind eye and letting things go, which ultimately led to the accident. Therefore, manager Wang Shumin should bear certain leadership and management responsibilities for this accident. 4. Preventive measures: 1. Strengthen safety education for laboratory operating employees, check carefully before each sampling, eliminate hidden dangers in time, and replace wires every two months. 2. The inspected sulfuric acid liquid is poured into a collection bottle, and then sent to a storage tank in the chemical production workshop after a certain amount. The current sampling and return method has been changed to each shift to reduce the probability of hidden dangers on the way. 3. Distribute acid-proof clothing, acid-proof gloves, and protective glasses to workers who take sulfuric acid samples as soon as possible. 4. From now on, all sampling will be carried out on foot. After taking the sample, it is not allowed to pick up or remove the sample from the customer's car. 5. Make a sampling bottle protection device. 6. The Quality Control Department took this accident as an example to conduct safety education for employees and find hidden dangers in each link of sampling and testing, formulate safety regulations for sampling and testing of chemical products (tar, sulfuric acid, crude benzene, washing oil, etc.), and correct * Inertial operation and violation of regulations, do a good job of safety.

like this* Most people turn a blind eye to the dangers of habitual violation of regulations, and they don’t realize that it is illegal work until they pay the price! Our security detail management leaves a lot to be desired ; Our personnel at all levels have insufficient awareness of safety responsibilities ; of our employees * Habitual violations still exist in large numbers ; Our safety work still has a long way to go!

Is this the laboratory technician's responsibility? After analyzing so many reasons, one of the key ones did not notice the "iron wire binding the sampling bottles". As a corrosive medium, who decided on the method of tying the sampling bottles with iron wires? Have the safety managers at all levels noticed this hidden danger for a long time?

This is an obvious* Inertia violations, especially riding a bicycle with one hand, are very dangerous.

The investigation report is written in great detail. Preventive measures, whether hazard source identification can be added.

You should use a suitable box to transport sample bottles. We have custom-made ones. How about a small insulated box with suitable foam stuffed inside?
Reply #72009-04-16
The most important thing is that the wire is used to lift the bottle. Now our company has replaced all of them with plastic, which causes constant corrosion.

I think it’s because there are flaws in the company’s safety management. The sulfuric acid sampling bottles are tied with wire frames, which inherently poses safety risks. Why can’t we customize a box specifically to hold the sampling bottles? Wouldn’t this ensure both safety and time?

The most dangerous violation is* Habitual violation! Generally speaking, we all know how to handle large projects according to the procedures, but for small projects, * It is easy to ignore inertial items. It is recommended that the unit focus on the employees' daily work. * If you discuss habitual violations with all employees, you will definitely gain something! Punishment is not the purpose, you will gain wisdom after suffering a hardship!

is a typical* Consistent violations of rules and regulations,

Can I ride a bicycle casually in the factory? There is a problem with the management of this factory, or the layout is unreasonable. Why is the analytical laboratory so far away from the sampling place?
Reply #122009-04-23
People are arbitrary, especially in repetitive work. Sometimes rules and regulations are not binding enough. For example, when pedestrians cross the road, how many people wait until the light turns green? They usually wake up after something happens. Suggestion: Job positions should be assigned according to people's personalities, and comrades with strong safety awareness should take on greater responsibilities. People who lack safety awareness should be transferred if they are not suitable for the job. This post was last edited by hjptfq on 2009-4-23 16:48 ]
