Safeopedia explains Exposure Level
When a worker is exposed to contaminants (usually airborne contaminants like dust or fumes) for a specific period of time, that is referred to as the exposure level. Exposure level aims to assess the level of exposure for a given time, while exposure limits set standards for how much exposure to a particular substance is considered safe. Assessing exposure to airborne contaminants is an important component of workplace safety in many industries.
