Which statement is true regarding U.S. biohazard regulations?

The statement regarding the application of the OSHA General Duty Clause to biohazards in research laboratories accurately reflects the responsibilities and regulations surrounding workplace safety. Under the General Duty Clause, employers are required to provide a safe working environment for their employees, which includes protecting them from recognized hazards, such as biological agents that can pose a threat to health and safety. This clause permits OSHA to address safety issues related to biohazards, even when specific regulations for those hazards may not explicitly exist.

In research laboratories, biohazards may arise from materials such as bacteria, viruses, and other pathogens, and employers are obligated to take reasonable steps to mitigate any risks associated with these hazards. This includes implementing standard operating procedures, providing appropriate training, and ensuring the use of personal protective equipment. Therefore, the application of the OSHA General Duty Clause to biohazards is crucial for maintaining safety against potential biological threats in the workplace.
