Answer:
a. willful
Step-by-step explanation:
The Occupational Safety and Health Administration (OSHA) is a federal agency saddled with the responsibility of assuring and ensuring safe and healthy working conditions for employees by setting and enforcing standards, providing education, trainings and assistance to various organizations.
When Occupational Safety and Health Act inspectors discover a hazard in which illness or injury incurred is unlikely to cause death or serious physical harm, but the violation does have a direct impact on safety and health, it reports a willful violation.
