True or False: If exposed to blood or potentially infectious materials at work, the school district provides an HBV vaccine at no cost.

The answer is true because under the Occupational Safety and Health Administration's (OSHA) Bloodborne Pathogens Standard, employers are required to offer the hepatitis B vaccine series to all employees who may be exposed to blood or other potentially infectious materials in the workplace, including school buses and related duties. This vaccination must be provided at no cost to the employees, ensuring that they are protected against potential exposure to hepatitis B, which can be a serious health risk.

This requirement is part of the employer's obligation to maintain a safe work environment and reduce the incidence of bloodborne pathogen transmission. The availability of the vaccine to all employees, rather than only some or only in specific emergency situations, underscores the importance of proactive health measures in safeguarding staff who might encounter such risks.
