California Registered Dental Assistant (RDA) Written Practice Exam

At which interval must employees receive training regarding hazardous chemicals?

1. Annually

2. Upon hire and whenever a new hazard is introduced

3. Every six months

4. Only upon hire

The correct answer is: Upon hire and whenever a new hazard is introduced

Employees must receive training regarding hazardous chemicals upon hire and whenever a new hazard is introduced. This is in accordance with the Hazard Communication Standard (HCS) set by the Occupational Safety and Health Administration (OSHA). This standard requires employers to train employees on any new hazards that may arise, such as new chemicals being introduced in the workplace. While annual training may be a good practice, it is not required by the HCS. Similarly, training every six months may be beneficial, but it is not required unless a new hazard is introduced. Only providing training upon hire is not sufficient, as new hazards may arise after an employee has already been hired. Therefore, option B is the most accurate and complete answer.
