2, brick, sand, pulp and other materials should be neatly stacked, keep the road clear, ditch, pit are not allowed to pile up materials.
3. Bricklaying and bricklaying on the scaffold of chimney maintenance project shall not be outward, and objects shall not be thrown at the opposite side or under the scaffold board to avoid injury.
4, no scaffolding or loose scaffolding. Bricks, materials and objects should be piled up smoothly on the roof or scaffolding.

Masonry principle
Therefore, the following five principles should be followed in the process of transformation:
1. For buildings with brick-concrete structure, all reinforced concrete walls cannot be dismantled and doors cannot be opened. Brick walls more than 24 cm thick are generally load-bearing walls and cannot be easily demolished and rebuilt.
2. The door frame is embedded in concrete and should not be removed. If it is dismantled or modified, it will destroy the building structure, reduce the safety factor and make it more difficult to reinstall the door.
3. The low wall beside the balcony cannot be removed or changed. There is a door and a window on the wall between the room and the balcony. These doors and windows can be removed, but the wall under the window can't be removed, because this wall is a "counterweight wall" and plays the role of provoking the balcony like a heavy object. If this wall is torn down, the bearing capacity of the balcony will be reduced, leading to the balcony falling.
The beams and columns in the room can't be changed. Beams and columns are used to support the floor above. Demolition or reconstruction will cause the upper floor to fall off, which is quite dangerous, so beams and columns must never be demolished or rebuilt.
5, the reinforcement in the wall can't move. When laying pipelines, the steel bars shall not be cut. If the reinforcement is damaged, it will affect the bearing capacity of the wall and floor, leaving a safety hazard.
