Be aware of co-workers who have a distinctive appearance, such as bright-colored shirts or shiny new hard hats, because these workers may be ___ to you or others.

• A. contagious
• B. inconsequential
• C. non-hazardous
• D. a safety hazard

Answer: (D)

On a job site, someone who stands out with bright clothing or a shiny new hard hat can signal that they’re new or not yet fully integrated into the crew’s safety practices. That unfamiliarity can mean they don’t yet know the specific hazards on the site, the established flow of work, or the exact PPE and procedures required. As a result, their presence can introduce risks for themselves and for others, making them a potential safety hazard.

The other options don’t fit because they don't address the safety risk that comes from someone who may be inexperienced or unaware of site rules. Contagious or non-hazardous traits don’t apply here, and labeling them inconsequential ignores the potential for misunderstandings or unsafe actions that can arise from inexperience.
