Matters needing attention in the construction of desulfurization tower
1 Machine calibration
According to the construction requirements, the validity and inspection of the equipment and tools in the factory should be carried out first.
2 Risk Identification
Considering the smooth implementation and safety of the desulfurization tower project, the risk of the site is assessed and identified one by one! __________
2.1 Group Cooperative Work of Altitude Work and Cross Work
风险源(危害因素):未正确使用安全用品、用具; 脱硫塔施工人员注意力不集中;防护设施器材缺失、不完善;物品放置不妥;多人协同作业时无指挥、动作乱。可能的事故后果:高处坠落、落物打击、人员触电、人员砸碰磕绊挤压、设施损坏!控制措施:四级 L0M 监督人员按职责到位，多人协同作业必须有人指挥、协调、确认设立专职监护人，做好施工前5min安全隐患排查和签字见证，加强安全意识，采取防护措施:
Risk sources (hazards): incorrect use of safety supplies and appliances; inadequate attention of desulfurization tower builders; absence and imperfection of protective equipment; inappropriate placement of articles; lack of command and disorderly movements when many people work together. Possible accident consequences: falling, falling objects strike, electric shock, stumbling and extrusion, facility damage! Control measures: Level 4 L0M supervisors are in place according to their duties, many people must be directed, coordinated, confirmed the establishment of full-time guardians, do a good job of 5 minutes before the construction of potential safety hazards investigation and signature witness, strengthen safety awareness, take protective measures:
(1) Correct use of seat belts and tool bags as required:
(2) Construction at high altitudes should eliminate falling objects in upper space, erect isolation measures such as "putting up protective nets, recovering in time after dismantling protection in frontier operations, or implementing hard pole protection and warning signs; there should be warning zones below the working face" to set up safety warning signs or other protective isolation measures to strengthen monitoring operations;
(3) Do not throw tools or materials up and down; they should be firmly tied up when hoisting.
(4) It is forbidden to climb unstable frames and trample on asbestos boards, tiles and other light materials. When necessary, strong scaffolds should be laid and fixed.
(5) All personnel entering the working site of the desulfurization tower shall wear labor insurance clothes according to the regulations, and shall be equipped with occupational protective articles according to the construction needs;
(6) The trench "pit" hole "hole cover board" fence removed during construction must be restored in time or effectively isolated when leaving the site.
2.2 Peripheral Protection
Risk Source (Hazard Factor): During the construction of desulfurization tower, people enter other equipment, pipeline operation area, causing the operation area to stop or cause their own damage! Possible accident consequences: causing partial shutdown, personnel injury! Control measures: doing peripheral protection in site construction, preventing unrelated personnel from entering, and preventing site constructors from entering other areas.
2.3 Pharmaceutical Safety Management
Risk source (hazard factor): Pull up construction warning line before construction, prohibit other types of work from entering within the scope of construction, take precautions around construction site, prepare necessary water sources, etc. Possible accident consequences: cause burns "burns accident! Control measures: employees must wear labor protection articles correctly according to regulations when on duty! Obey safety operating rules, observe labor discipline, and strictly prohibit drinking. On duty! In the construction area to designate a safe passage to ensure the smooth passage, pay attention to a variety of safety signs, do not arbitrarily remove or occupy a variety of safety protective devices, "safety signs and detection instruments, etc!"
2.4 Construction Electricity
风险源(危害因素): 脱硫塔施工过程中接线"接地"接零有缺陷时易造成人员触电"裸露导体温度过高引燃周围可燃物!可能的事故后果:人员触电"设施损坏"火灾!控制措施:电工施工作业时要落实监督人员职责，按照规章制度挂牌，电工要严格执行电气安全技术操作规程，线路敷设要有防护措施，线路接头做好防水"缘包扎，移动式电器手持电动工具做到$一机一闸 一保护%!非专职电工严禁涉电!
Risk Source (Hazard Factor): In the process of desulfurization tower construction, the defective connection of "grounding" is liable to cause electric shock of personnel "high temperature of bare conductor ignites surrounding combustibles!" Possible accident consequences: personnel electric shock"facilities damage"fire! Control measures: Electrician construction work should implement the responsibilities of supervisors, listed in accordance with rules and regulations, electrical workers should strictly implement the technical operating rules of electrical safety, Line laying should have protective measures, line joints should be waterproof "insulation bandage", mobile electrical hand-held power tools to achieve $1 machine, one gate, one protection%! Non-full-time electricians are strictly prohibited from involving electricity!
