The main hazard factors in monolithic construction are considered to be the collapse of the formwork system, injury to workers during installation, electric welding tasks.
General safety requirements
Employees over the age of 18 who have been instructed are allowed to carry out monolithic works.
There are several types of instruction, each of which is conducted by a safety engineer:
- introductory – conducted when hiring an employee;
- primary – before performing concrete works on a new construction site;
- repeated – for prevention purposes or when detecting minor safety violations;
- unplanned, it is carried out after an emergency;
- target – before performing non-standard work.
Monolithic work must be carried out by workers in overalls (helmet, mittens, overalls, goggles and mask, there must also be safety belts).
Safety precautions during installation and dismantling of formwork systems
It is necessary to adhere to the following requirements:
- Strangers are not allowed to the construction site.
- The formwork must be installed exclusively on a reliable, solid and level platform.
- Large shield systems are assembled on the ground, after which they are mounted using lifting equipment.
- Wall formwork systems are installed in stages. On the first tier (up to 5.5 m high), work is carried out using mobile ladders, and the 2nd tier is installed using movable scaffolding. Only climbers with appropriate tolerances are allowed to install formwork systems at a height of more than 8 meters.
- Only after checking the quality of the installation of the first tier, you can proceed to the installation of the next.
- When using reusable formwork systems, special attention should be paid to checking the condition of locks, bolts and other fastening elements.
- The stability of the formwork is checked daily before the start of monolithic work.
Disassembly of the panel formwork is carried out from top to bottom.
Safety precautions when pouring concrete
Before work, it is necessary to check the operation of mechanized equipment, the discharge of the solution should be carried out from a height of no more than 1 meter.
