A more thorough explanation:

Definition: Injurious exposure refers to contact with a substance that can cause harm or injury if a person is repeatedly exposed to it over time. This term is commonly used in the context of workers' compensation, where an employer may be held responsible for harm resulting from injurious exposure.

Examples: An example of injurious exposure could be a worker who is regularly exposed to toxic chemicals in a factory. Over time, this exposure could lead to serious health problems such as lung disease or cancer. Another example could be a construction worker who is repeatedly exposed to loud noises on the job, which could result in hearing loss over time.

These examples illustrate how injurious exposure can occur in a variety of work environments and can lead to serious health consequences if not properly addressed. It is important for employers to take steps to protect their workers from injurious exposure and to provide appropriate compensation and medical care if harm does occur.
