What is one consequence of failing to implement safety protocols?

Failing to implement safety protocols can result in increased insurance costs. This occurs because when safety measures are neglected, the risk of accidents and injuries on the job site rises. As the frequency and severity of incidents increase, insurance companies may raise premiums to cover potential claims associated with those accidents. Higher insurance costs can place a financial burden on the company, as they directly affect operating expenses.

In contrast, improved project timelines would generally be a benefit of safety protocols, as a safe work environment allows for smoother operations and reduced downtime. Less communication among workers and reduced employee morale are often negative effects of an unsafe environment, but they are not direct financial consequences like increased insurance costs. Therefore, the most significant consequence among the options provided is the financial impact of increased insurance costs stemming from inadequate safety measures.
