Final answer:
Different job functions can lead to different levels of exposure to hazardous materials through absorption and inhalation.
Step-by-step explanation:
Different job functions can lead to different levels of exposure. Most occupational exposures are caused by absorption through exposed skin such as the face, hands, forearms, neck, and chest. This exposure is sometimes enhanced by inhalation in settings including spraying operations in greenhouses and other closed environments, tractor cabs, and the operation of rotary fan mist sprayers.
