Accidents and occurrences in construction projects are inevitable for workers and even in some cases personnel, but precautions should be taken to minimize the occurrence of accidents, and this will only refer to the implementation of the executive instructions of the people present in the project and all Stakeholders must act in accordance with the rules and protocols of the template designer and in accordance with the safety rules to the executive points in the project to prevent any unfortunate accident that will have consequences for the employer, workers and even their families.

For this purpose, points should be observed in the implementation of the structure and formwork to prevent unfortunate events. Below are some of the factors to reduce the collapse of the mold, the collapse of the mold may be local or general, and may also be in part or Some conditions of the molds move compared to the original conditions, in which case the molding system must be opened and reinstalled. If the molding system has sufficient strength, such damage will not occur.

Some of the causes of mold collapse are as follows:

1- Lack of control of concreting speed

2- Incorrect or incomplete design of the molding system

3- Inadequate or incorrect piling

4- Incorrect connections

5- Error in installing jacks

6- Early dismantling of molds

7- Insufficient resistance of molding materials

8- Negligence of workers or supervisors

9- Making changes in the equipment provided by the manufacturer

10- Improper method of shaking or compacting concrete

11- Improper or insufficient details and connections of bracing

12- In some cases, the collapse of molds may be due to non-compliance with regulations and standards.

One of the most important factors in the collapse of molds are roof jacks, which should be paid special attention in their design and control.

To avoid the risk of falling from a height

1- Installing protective fences

2- Using seat belts and scaffolding

3- Use of anti-fall systems and movement restrictions

To prevent the movement of materials and cargo

1- Observing the principles of ergonomics and the place of cargo access

2- Using cranes, forklifts and elevators

To avoid the risk of electric shock

1- Installation of earth equipment system

2- Using dual insulation

3- Preventing water and moisture from coming into contact with electrical appliances

To prevent the mold from tipping over

1- Tightening loose molds

2- Inspection of molds

3- Using appropriate personal protective equipment

Observing the safety of project stakeholders, including template designers, engineers / architects, workers, supervisors and supervisors, is a priority in implementing safety principles.

Designers and creators of templates are required to comply with local and national regulations.

Other factors that can prevent mold collapse are as follows

1- Loads and pressures that are applied on vertical jacks

2- The forces resulting from falling on the deck

3- Mold design against dynamic loads

4- Preventing the collapse of temporary barriers
