A multi-pronged approach to enhance the safety of dust workplaces

In order to draw lessons from the “4•16” dust explosion accident of Dongmao Shuangma Chemical Co., Ltd., Rugao City, Jiangsu Province, according to the “4•16” dust explosion of the General Administration of Safety Supervision of Rugao City Shuangma Chemical Co., Ltd., Nantong City, Jiangsu Province. "Report on accidents" (Safety Supervision Administration No. 3 [2014] No. 34) requires that the Shanghai Municipal Bureau of Safety Supervision issued a notice a few days ago and adopted various measures to comprehensively strengthen the safety production of dusty workplaces in the city, and to prevent production accidents of various types of dust explosions from occurring. .

First, in conjunction with the work of the "Asian Summit" on safe production support, it immediately launched a full-scale, pull-net-style safety inspection and continued to conduct in-depth investigation and treatment of hidden dangers. It is required that all levels of safety supervision departments and related holding (group) companies figure out the specific quantities, distribution status, and hidden troubles of all production and business units and workshops, warehouses, confined spaces, and other production sites with dust explosion hazards in their own areas and systems. Situation and the establishment of situation files; focus on checking the equipment and facilities for ventilation and dust removal in dust explosion hazardous locations, installing explosion-extinguishing, explosion-proof, explosion-proof devices, and implementing safety measures such as fire protection, explosion protection, and anti-static protection; Analyze and test all combustible dusts in the enterprise, grasp the limits of each dust explosion and detonation energy value, formulate targeted measures to eliminate dust safety hazards, and urge the hazardous chemicals enterprises in the region and this system to strictly enforce the suspension of flammability before May 31st. The annual inspection and maintenance of explosive sites (chemical installations), the control of gas filling stations for finished products, the limitation of the frequency of production process adjustments, and other control measures; continued in-depth implementation of anti-"three violations" and "non-violation" actions in the production safety field to ensure that "Asian Summit" holds venues, event venues, and other neighboring enterprises to produce safety And resolutely put an end to have a greater social impact of production safety accidents resolutely reduce the general production safety accidents and promote the city's production safety situation continues steady improvement.

The second is to urge related companies to strengthen the safety management of dust explosion hazardous locations, strictly implement relevant national laws and regulations, establish and improve dust safety management rules and regulations, ensure the prevention and control of dust explosion safety input, and conduct risk identification for workplaces with dust explosion hazards. Assessment, equipped with detection instruments and timely detection, to prevent dust concentrations from reaching explosion limits; to improve ventilation and dust removal facilities, and to install relatively independent dust removal systems in accordance with the process segmentation; dust collection points should be installed at all dust production points; Settlement of dust, ensure the timely elimination of dust accumulation, prevent excessive concentration of dust; keep the dust-removal system vented, explosion-proof device in good condition and normal operation; strengthen employees' safety education and fire and explosion-proof technical training, ensure that employees have the necessary knowledge of dust explosion, master Safe operating skills.

The third is to strengthen the safety management of hot work and other operations. Requested enterprises to improve rules and regulations for operational procedures such as hot spots in dust explosions, strengthen operational management of operations, strictly implement safety measures, clearance of work ticket approvals, and safety custody check; and strictly carry out risk assessment before removing fire to remove combustible dust. And equipped with adequate fire extinguishing equipment to separate the fire zone and other zones to ensure that no dust enters the hot zone during hot work and cooling during the hot fire to prevent dust explosion caused by hot work; to arrange on-site safety with emergency rescue knowledge Guardians, equipped with necessary communications and rescue equipment and emergency facilities to ensure prompt and proper handling of emergencies.

The fourth is to increase safety supervision. We will further intensify safety supervision laws, regulations, standards, publicity, training, and strengthen supervision and inspection; continue to promote consensus on safety supervision, build, share, and consolidate the cooperation of “regular consultation, linkage law enforcement, hidden prosecution, and information sharing”. The safety supervision mechanism strictly investigates and enforces violations of laws and regulations and seriously investigates the responsibility for accidents. For intermittent chemical production enterprises, it focuses on strengthening safety management such as change management, production switching, product plan adjustment, automatic control system effectiveness, and safety facility integrity; Promote the construction of a safe production standard for enterprises as a starting point, and further promote enterprises to implement their main responsibilities.

The fifth is to strengthen emergency response. It is required to improve contingency plans, improve operational skills of employees, implement emergency resources such as emergency organizations, rescue teams, equipment, and supplies, and strengthen emergency response drills; urge leading cadres in key areas and key enterprises to take steps to strengthen emergency duty, and all on-duty personnel stick to their positions. Responsibility for due diligence, promptly and properly dispose of the problems occurred, prevent improper handling, and cause accidents in a timely manner; earnestly implement the accident information reporting system, unblock the channels for information submission, ensure that information is reported in a timely and accurate manner, and resolutely prevent delays, omissions, and reports of accidents. Information; From May 15 to May 31, according to the “One-day report” requirement, submit the relevant information to the Municipal Safety Supervision Bureau.
