In response, relevant experts pointed out that in view of the characteristics of chemical production, the emergency plan for safety accidents formulated by chemical companies must be in line with the actual situation of the company and be practical, especially highlighting the details. Only in this way can accidents be avoided and properly handled. emergency.
A yellow phosphorus production expert said that yellow phosphorus is a high-risk chemical. If the above-mentioned enterprises can allow employees to master relevant safety knowledge in advance and formulate targeted emergency plans, this accident can be avoided completely. For the key parts of the company prone to accidents, the company's safety emergency plan should be able to cover it, and allow operators to know in advance precautions, or to master the skills in the usual drill. In addition to the characteristics of flammability, explosiveness, high temperature, and high pressure, chemical production generally also has the characteristics of a variety of materials in tanks, kettles, pipelines and other closed containers to carry out violent chemical reactions, which requires chemical companies to develop The safety accident emergency plan must have diversity and pertinence.
However, in reality, existing safety emergency plans for some chemical companies cannot be consistent with actual production conditions. For example, many companies have conducted fire safety drills related to fire extinguishing, and most of the fire drills of these companies are not located at the production site, but at the site outside the production zone. The fired materials in the drills are also different from the actual production. , very lack of actual combat. "To some extent, this kind of safety drill just allows employees to master the use of fire-extinguishing equipment and can't really deal with actual fires. This type of plan has no practical significance at all." Jiangsu Limin Chemical Industry Co., Ltd. Safety Chief of Section Zhuang Wendong said.
It is understood that it is the lack of practical emergency plans that have caused some chemical companies to suffer huge losses of property and even cost their employees their lives. A young woman worker from a chlor-alkali company in Jiangsu was inadvertently splashed into the back with mother liquor of chloroacetic ACID during production operations. However, all the personnel present at the time, including the female worker, did not expect to have any serious consequences. After the incident, the female worker simply rinsed his back with clean water and changed his overalls to continue working. On the second day, however, the woman’s back was red and swollen and his expression was paralyzed. Although his family members sent him to the hospital for emergency treatment, he failed to save his life. After being diagnosed by a doctor at the Occupational Disease Hospital, the female worker died of organophosphate inhalation into the body.
Experts pointed out that the accident was also a lack of detail and pertinence of a safety emergency plan. Many chemical materials belong to toxic hazardous chemicals and are highly invasive to the human body. Enterprises should describe all hazards that may cause harm to employees and allow employees to gain relevant knowledge. These are the critical issues that chemical companies need to solve to formulate a safety emergency plan, and it is also the reality that the company's safety management must face.
The reporter also communicated with managers of enterprise safety who had done a good job of emergency plans. Limin Chemical Company stated that the company's safety emergency plan should be based on the characteristics of the post, one case of one job, and not the same. In particular, each key post should be sorted out, the safety hidden factors should be placed under effective supervision, targeted preventive measures should be formulated, and the post operators should be mastered as the content of the should-to-be meetings.
On the anniversary of the Sichuan Wenchuan earthquake on May 12 last year, the company held a chemical enterprise earthquake and secondary disaster emergency drill, in which a number of specific positions were set up to simulate safety accidents. For example, once an earthquake triggers a fire, how to quickly start self-contained power generation equipment and extract water from the reservoir to extinguish the fire in the event of an external power outage; simulate the occurrence of liquid ammonia storage tank leakage in the raw material area and how to make rapid disposal; also assumed The production of post-discharged carbon disulfide toxic gases, operators how to take anti-drug measures to escape the exercise of the content.
Zhou Xueqiang, chief of safety and environmental protection department of Jiangsu Hengsheng Chemical Fertilizer Co., Ltd., believes that the materials involved in chemical production generally have the characteristics of being easily corroded and easily contaminated, and the production process is relatively complex. Any omission in any link may lead to accidents. Therefore, chemical companies must, in accordance with the accident classification standards stipulated in the “Regulations for the Reporting and Investigation of Production Safety Accidents†formulated by the relevant state agencies, formulate targeted safety emergency services for the key parts and key links that may lead to accidents. Plan.
Pigments are used for coloring paint, ink, plastic, construction, fabric, cosmetics, food, and other materials. Most pigments used in manufacturing are dry colorants, usually ground into a fine powder. For use in paint, this powder is added to a binder (or vehicle), a relatively neutral or colorless material that suspends the pigment and gives the paint its adhesion. A colorant can act as either a pigment or a dye depending on the vehicle involved. In some cases, a pigment can be manufactured from a dye by precipitating a soluble dye with a metallic salt.
Emergency plan for safety in enterprises needs to be further elaborated
In late January, a yellow phosphorus fire accident occurred in a phosphate company in northern Jiangsu Province. The entire tank of yellow phosphorus burned down and all tens of square meters of working surface were burned. According to the internal analysis of the company, the cause of the accident was that the overhaul workers improperly disposed of liquid phosphorus. According to a survey by the reporter, several maintenance workers in the accident had never conducted drills on the safety of this position. When the accident occurred, they could only escape from their own lives.
