As of August 16, 2015, the Tianjin Port explosion has killed 112 people, including 21 firefighters;
video from the scene shows the horror of the explosion: mushroom clouds, glass in high-rise buildings shattered, hundreds of kilometers away, and thousands of residents homeless. Analysis says the second explosion is equivalent to 21 tons of TNT. This accident will be chemical safety and volkswagen seems far away from the problem once again pulled back into the public eye, it once again sounded the "heavy chemical era" of safety alarm!
all along,
coatings
industry is also a chemical accident industry, as a high-risk industry,
coating enterprises
never know tomorrow and accident which come first. Tianjin Binhai New Area dangerous chemicals warehouse explosion, for the paint enterprise safety production once again sounded the alarm. The author believes that after this accident, the paint industry as a high-risk industry, will usher in a round of safety inspection.
production safety involves many disciplines, strong professionalism. Related to the paint factory general plan, fire and explosion prevention, lightning and static protection, electrical safety, production equipment safety, industrial pipeline safety, safety signs, dust and anti-virus, noise prevention, protective supplies, paint production safety and safety management and other aspects of the content. Strengthening safe and standardized production will play a positive role in ensuring the safety and supervision and management of paint production.
paint production with flammable, explosive, toxic, high temperature, high pressure, corrosion and other high-risk characteristics. As a result, there is a greater risk than other industrial sectors.
(1) paint production using a wide range of raw materials, semi-finished products and finished products, the vast majority of which are flammable, explosive, toxic, corrosive hazardous chemicals. This puts special demands on the storage and transportation of these raw materials, fuels, intermediates and finished products in production.
(2) paint production requirements of the process conditions are harsh. Some chemical reactions are carried out at high temperatures and pressures, and some at low temperatures and high vacuums. Such as thermal paint and resin synthesis process, in addition to the general use of steam and heat carrier heating, there is also the use of open fire heating, in the trial production, inspection and analysis also use a variety of electric ovens, electric furnaces and other heating facilities, in the maintenance process also has electric (gas) welding and other fire sources, but also increased the risk of paint production fire, explosion.
(3) electrical equipment, poor safety. In the paint production site, the use of electrical equipment such as mechanical and electrical facilities, distribution facilities, electrical wiring, exhaust fans, switches and so on more, and the existence of selection, installation does not meet the explosion-proof norms, line aging, poor safety and other unsafe factors, is a major factor leading to combustion, explosion.
(4) production methods are highly automated and continuous. Paint production has changed from backward manual operation and intermittent production to highly automated and continuous production, production equipment from open to closed, production equipment from indoor to open, production operation from decentralized control to centralized control, and from manual operation to automatic instrument operation, and then developed into computer control. Continuous and automatic production is the inevitable result of large-scale, but the control equipment also has a certain failure rate.
coating industry occupies an important position in the modern industrial system, and it is necessary to develop the coating industry. However, in view of the safety characteristics of the coatings industry, whether in production operations, or daily risk prevention, the global
Coatings Network
believes that it is necessary to widely publicize the paint industry's safety knowledge, regulatory system updates and enterprises on the importance of safe production.
with the rapid development of paint production, its production scale, process technology, product structure, production equipment and raw materials have undergone new changes. Therefore, paint enterprises should follow the objective law of paint production, with a scientific attitude to continue to explore and study the safety problems in paint production, from which to master and take the necessary safety technical measures, effective control and prevention of accidents and disasters, to protect the lives and health of paint producers, to ensure that national and enterprise property from loss, and promote the sustainable development of paint production.
(1) reform of process conditions, the use of low-toxic or non-toxic raw materials, instead of highly toxic or toxic raw materials. Use heavy aromatics instead of xylene, iron oxide red, iron yellow instead of red Dan, Yellow Dan production rust-proof paint and so on.
(2) efforts to develop non-toxic harmless new coatings, is the direction of the development of coatings, but also to prevent occupational poisoning of the fundamental measures. Such as the
water-based coatings
as the representative of non-toxic harmless coatings.
(3) strict operation, to avoid human error and cause the leakage of poison accidents and disorderly discharge phenomenon, reduce the pollution of poison to the environment and harm to people.
(1) Gradually transform and replace older open-type, unsafe, seriously polluted equipment, such as the use of closed grinders to replace the three-roller machine, with closed filters to replace the plate frame filter, and so on, and strive to achieve closed operations to reduce toxic hazards.
(2) for noise, vibration of large blowers, air compressor, ball mill, sander, punch and other equipment, can take sound absorption, sound insulation, vibration reduction, the use of noise-proof supplies or the establishment of sound-proof operating room and other anti-vibration noise reduction measures to reduce noise, vibration hazards.
(3) establish a system of regular maintenance and maintenance of equipment, strengthen the inspection and maintenance of equipment, prevent the running, running, dripping and leakage of equipment, and ensure the safe and proper operation of equipment.
(1) engaged in dust operations, such as ingredients, rolling tablets, resin feed, etc., must be set up ventilation and dust protection devices, to maintain good and effective, reduce the harm of productive dust to the human body.
(2) To open or closed poor jobs and equipment, such as nitro-thin materials and finished packaging, solvents and lacquer slurry storage tanks, cylinders, etc. to adopt mandatory pumping, exhausting devices, reduce the concentration of flammable, toxic gases in the work site, to ensure the safety and health of operators.
(3) paint production in other production sites, should also strengthen natural ventilation or mechanical ventilation, in order to reduce toxic concentration and heat protection cooling.
(1) to establish and improve the safety management system, and effectively strengthen the storage, transportation, use and collection of toxic and harmful substances management. Prevent the leakage, spread and loss of poisons.
(2) conscientiously implement the "new construction, alteration, expansion" project "three simultaneous" provisions, that is, labor safety and health and dust poison control measures, must be designed at the same time as the main project, construction, at the same time put into production.
(3) strengthen the regular detection and management of dust and poison operation sites on the production site, keep abstring on the changes in the concentration of toxic substances, find and solve existing problems in a timely manner, and promote safe and civilized production.
(4) adhere to the "three-level safety education" system, the use of "toxic knowledge card" and other effective ways to widely carry out safety and health, dust hazards and prevention education, improve the safety of the vast number of workers, health awareness and self-protection quality.
(1) strengthening personal protection is an important measure to ensure the safety and health of operators. Therefore, the operator in the production process must adhere to the correct use of personal protective equipment, the use of protective clothing, protective masks, protective gloves and dust appliances, etc. , consciously develop a diligent hand washing, bath after work, not in the production site to eat, smoke, drink water and other good hygiene habits, in order to prevent the wrong poison, resulting in poisoning.
(2) to enter the container, equipment operation, in addition to strict examination and approval procedures, must correctly use anti-virus facilities to prevent poisoning.
(3) For employees engaged in toxic and harmful operations, regularly organize medical examinations, and organize convalescies and treatment for workers who are found to be suffering from occupational hazardous diseases, personnel who are not suitable for engaging in toxic and harmful operations shall be transferred or transferred in a timely manner.
(4) In addition to occupational health education, employees who enter the factory should also organize health checks, establish and improve health examinations and occupational disease files, and strengthen occupational disease monitoring.
alarm bells ringing, we can't always sound the safety alarm at the cost of our lives!" Safety first" is an eternal theme, paint enterprises only safe development is healthy development, harmonious development. Therefore, the safety work is far greater than the rapid development.
