do you know about the safety management of erection and use of scaffolds on the construction site of gasifier?

● during the construction of gasifier project, the metal double bent frame shall be used for the erection of scaffolds, and the load shall meet 270kg / m2. if it needs to be overloaded, it can be used only after accounting and reinforcement treatment.

● in addition to bearing a certain load, the erected scaffold is required to be stable, firm and reliable, so as to ensure the stability and firmness under the condition of no overload and climate change during the construction period, so that the scaffold will not deform, tilt, shake and collapse during the use, and ensure the safe operation of the construction personnel.

● ø 48-51 shall be used for scaffold members, δ= 4 mm steel pipe, according to the need to choose different length of rod, the steel pipe with serious corrosion, bending, flattening or crack is forbidden to use.

● malleable castings for fasteners. δ= 2-3mm steel springboard, 1.5-2mm in length and 230-250mm in width, with connecting devices at both ends. the springboard surface shall be drilled with anti-skid holes. it is strictly forbidden to use cracked and twisted scaffold boards.

● the scaffold body must be firmly connected with the steel structure, frame and frame.

● cross bracing and diagonal bracing shall be set at both ends and corners of the scaffold and every 6-7 vertical poles, and the included angle with the ground shall not be greater than 60 degrees. the bottom end of the throwing bracing shall be buried in the ground for 300-500mm. when the height of the scaffold is more than 7m or throwing bracing cannot be set, a connecting rod shall be set every 4m and 7m to connect the scaffold with the platform or frame.

● in terms of the height of the fixed pole, one is set every 4m to prevent the shelf from toppling outward.

● the intersecting and protruding ends of each scaffold member shall be greater than 100 mm to prevent the scaffold member from slipping.

● the scaffold (including safety net) erector must comply with the specification requirements. after the scaffold is erected, it shall be submitted to the safety department in charge of the project department and the user for joint inspection and acceptance. after receiving the experience, hang the striking signboard at the obvious place of the scaffold (the size is 400mm) × the scaffold that meets the requirements can only be used after hanging "qualified scaffold" (the signboard is blue on white background, and the operation bearing capacity, load limit, person in charge of use and person in charge of inspection shall be written on it). if the scaffold does not conform to the requirements, hang the sign of "unqualified scaffold is strictly prohibited to use" (the sign is in red on a white background, and the person responsible for rectification shall be indicated on it. only after it is qualified, can it be used.

● the scaffold should be erected from bottom to top and removed from top to bottom. warning signs shall be set around the demolition and special personnel shall be assigned to take care of it.

● special person shall be assigned to take charge of the scaffold demolition to prevent the scaffold collapse caused by recklessness and violation of regulations.
