Which factor is least likely to contribute to workplace safety?

Outdated equipment is least likely to contribute to workplace safety because it can increase the risk of accidents and injuries. When equipment is old or does not meet current safety standards, it may malfunction or break down, leading to unsafe working conditions. This makes it harder for employees to perform their tasks safely.

In contrast, effective communication, regular safety training, and hazard assessments all play vital roles in enhancing workplace safety. Effective communication ensures that all team members are aware of safety protocols and can report potential hazards. Regular safety training helps employees understand best practices and stay updated on safety procedures, significantly reducing risks. Hazard assessments allow organizations to identify and mitigate risks before they lead to incidents, creating a safer work environment.
