According to the CCTV news client, on May 9, 2024, an explosion occurred in the nitrocellulose production workshop of a chemical company in Laohekou City, Hubei Province, killing three people. The preliminary analysis of the accident was that the water level of the nitrocellulose pot in the nitrocellulose production workshop declined, and the local nitrocellulose lacked water, which decomposed under the action of high-temperature steam and continuously released heat, resulting in the explosion of the violent thermal decomposition of nitrocellulose in the pot. The exact cause is under further investigation.
In summer, there is an increase in high temperatures, thunder and lightning
Hazardous chemical accidents are prone and frequent
What are the precautions in the production and storage of hazardous chemicals?
Keep these tips away!

In the process of production and operation of enterprises
How should it be "explosion-proof"?
↓↓↓
01
Personnel must undergo safety training before taking up their posts
1. Employees must receive safety, management, and occupational health training before taking up their posts, and they can only take up their posts after passing the assessment.
2. Regularly conduct safety, management and occupational health training and education for employees.
02
The facilities and equipment in the factory meet the requirements
1. The equipment and facilities in the factory must be installed and equipped with lightning protection and electrostatic conduction facilities in accordance with relevant regulations, and the tests shall be carried out every year.
2. The electrical equipment must meet the national electrical explosion-proof standards, and the configuration of the electrical equipment must match the regional hazard level configuration requirements.
3. Monitoring and measuring equipment should be established and regularly calibrated.
4. Production equipment and devices must be set up with safety facilities in accordance with national regulations, and regularly maintained and calibrated.
03
Strictly manage key parts and key devices
1. Smoking and the use of fireworks and other activities that generate sparks or static electricity are strictly prohibited in areas where hazardous chemicals are stored, produced and used.
2. Hazardous chemicals storage sites should be set up with obvious signs, indicating the name, characteristics, fire prevention measures and fire extinguishing methods, and equipped with necessary fire fighting equipment. The storage methods, facility requirements, storage arrangements, and storage limits of hazardous chemicals should comply with relevant regulations.
04
Strengthen risk management and control of non-routine operations
1. Implement list management for unconventional operations (including special operations, device start-up and shutdown, etc.), mobilize all employees to sort out the unconventional operations of the enterprise, form a list of unconventional operations of the enterprise, identify the risks of each unconventional operation, formulate and improve safety operation procedures and emergency response measures, and summarize and file them.
2. Before implementing unconventional operations, it is necessary to carefully study the content of risk identification, predict various risks, and understand risk scenarios; In the process of operation implementation, it is necessary to strictly implement the safety operation procedures, find abnormal situations, and take emergency measures; After the completion of the operation, the operation process must be analyzed and summarized, and the results of the analysis and summary must be completed in turn.
05
Strengthen the risk management and control of loading and unloading operations
1. Before loading and unloading operations, you should understand the physical and chemical properties of the goods, protection methods and precautions for loading and unloading operations, and wear the prescribed protective equipment.
2. Before loading and unloading, the electrostatic grounding wire should be connected first, the vehicle engine should be turned off, and the loading and unloading of goods should be stopped during thunderstorms.
3. During loading and unloading operations, operators should master the operating procedures and fireproof, explosion-proof and anti-virus requirements, and operate carefully to prevent leakage and overflow of goods.
4. When loading and unloading, the flow rate of the goods should be controlled according to the nature of the goods to prevent the accumulation of electrostatic charges and the generation of electrostatic sparks due to the fast flow rate.
06
Strengthen the management of construction operations
1. All workers are not allowed to carry fire, mobile phones and other contraband when entering the site, and are not allowed to wear work shoes with iron nails and clothing that is easy to generate static electricity.
2. All operators should strictly implement the relevant safety management system regulations, and if there is any violation, they will be dealt with according to the regulations.
3. For key construction operations, the "Construction Safety Plan" should be formulated, and key guardianships should be carried out to achieve the "three implementations" of guardians, fire-fighting equipment and safety measures.
07
Strengthen vehicle management
1. When the vehicle enters the reservoir area and the device area, it must wear a fire hat, install an electrostatic conduction device, and should maintain a sufficient safety distance, not allowed to block the fire escape, the driver is not allowed to leave the vehicle, and during the loading process, the engine of the vehicle must be turned off and the power supply must be cut off.
2. The safety management department of the enterprise shall inspect and spot check the warehousing vehicles, and stop them in time if they find violations.
3. The production management personnel shall inspect the vehicle according to the regulations before loading and unloading the vehicle and fill in the inspection form.
08
Strengthen surveillance, monitoring and labor protection
1. Safety alarm system and safety monitoring system should be set up in the fire hazard, toxic and harmful workplace.
2. Toxic gas monitoring should be carried out on the workplace on a regular basis and announced.
3. Necessary warning signs about occupational health and safety should be set up at the job site.
4. Employees on the job site should be examined once a year, and employees who are exposed to highly toxic or long-term exposure to toxic and harmful working environments should be inspected according to the type of chemicals they are exposed to.
5. Enterprises should be equipped with necessary anti-virus equipment and equipment, and conduct anti-virus training and anti-virus drills for employees on a regular basis.
09
Strengthened security checks
It is necessary to do a good job of daily inspections, regular inspections and temporary inspections.
