What should be done if a worker has been overexposed to asbestos?

In the event of a worker being overexposed to asbestos, the appropriate action to take is to ensure that the worker receives immediate medical attention. This is crucial because asbestos exposure can lead to serious and sometimes fatal health issues, such as asbestosis or lung cancer. Prioritizing the worker's health and safety is essential in handling such a hazardous situation.

While writing a letter to provide facts about the exposure can be part of documenting the incident, it does not directly address the immediate health risks faced by the worker. Therefore, it is not the essential first step when exposure has occurred. Actions like notifying OSHA or removing the worker from duties might also be necessary, but they do not replace the need for immediate medical evaluation and treatment. Taking care of the worker's health is the fundamental priority in this scenario.
