Proper marking of the construction site, all visual messages regarding hazards, and acoustic information are the strong points of VM, improving safety and working conditions. Moreover, the use of visual messages shapes the occupational health and safety culture and awareness among employees. Effective implementation of VM requires knowledge of the proper implementation of VM, supervision, compliance with applicable rules, awareness of health and safety, involvement of management and employees in compliance with applicable rules, and clear communication about the changes introduced, the failure of which will be a weakness of the proposed solution. The implemented visual management activities will result in improved safety on the construction site among potential employees and external entities. Threats that employers may face may include the need for frequent, additional supervision of subcontractors' employees who are reluctant to follow established rules and do not comply with visual messages. The implementation of VM (opportunity) may translate into building employee awareness of implementing solutions aimed at improving work safety. Visual messages, information about threats and dangerous situations, and better communication significantly improve the organization of work on the construction site, which results in reduced accidents and a positive reception on the market. The analysis of the strengths and weaknesses of Visual Management, as well as the opportunities and threats related to its implementation and use, is presented in Table 5.  
Standardization is an important element of the LM concept because it reflects best practices in the workplace and describes the safest and most effective methods of performing work at the required level of quality. Hence, standardization was used to reduce 13 illustrative hazards (Table 3). Carrying out construction works in accordance with the adopted standards (e.g., moving along designated paths, correct and safe use of equipment, materials and tools, and maintaining order) introduces a unified method of carrying out all tasks, allows maintaining order in the construction site, limiting unnecessary movement of workers in areas of increased risk and build awareness of occupational health and safety. The factors mentioned above affect work safety, which is the strength of standardization in this area. Lack of knowledge, incorrect implementation of standards, lack of supervision by superiors, non-compliance with the procedures introduced by employees, lack of awareness, lack of training, and communication regarding the changes introduced in the applicable standards will constitute weaknesses that affect occupational safety. The effect of standardization and compliance with the introduced rules will be an improvement in safety on the construction site among potential employees and other external entities (opportunities). Failure of subcontractors' employees to comply with work and safety standards, as well as the need for frequent supervision of subcontractors' employees related to compliance with standards, may pose a hazard to the effectiveness of standardization in construction work. An analysis of the strengths and weaknesses of Standardization, as well as opportunities and threats related to its implementation and use in the construction industry, is presented in Table 6.  
Poka-Yoke allows for the elimination of dangerous events on the construction site by introducing technical solutions that identify and warn against hazards or interrupt the operation of devices (P-Y allowed for the reduction of six potentially identified hazards--Table 3). Reducing the possibility of an employee making an error through properly designed Poka-Yoke solutions has a positive impact on the safety of the tasks performed, especially when the activities performed are repetitive and may cause, for example, distraction. To achieve the goal, i.e., eliminating the possibility of making an error leading to an accident, the implemented technical solutions should be properly designed and implemented.
