What is one common hazard in a work zone that must be communicated to workers?

In a work zone, the presence of moving vehicles and equipment represents a significant hazard that must be communicated to workers. This is crucial for maintaining safety because workers often operate in close proximity to these vehicles and machines, which can pose risks of injury or fatal accidents if not properly managed. By informing workers about the potential dangers associated with moving vehicles and equipment, they can take necessary precautions, such as remaining alert, wearing high-visibility clothing, and following established safety protocols. Effective communication about this hazard is essential in promoting a safe work environment and reducing the likelihood of incidents in active work zones.
