What is the most common route of exposure to hazardous materials?

Inhalation is indeed the most common route of exposure to hazardous materials. This occurs because many hazardous substances, particularly gases, vapors, and airborne particulates, can easily enter the respiratory system when they are inhaled. The lungs provide a large surface area for absorption, making it efficient for harmful substances to enter the bloodstream and affect the body rapidly.

In many work environments, especially those involving chemicals and industrial processes, inhalation of airborne hazards is a prevalent concern. Factors such as inadequate ventilation, the use of volatile substances, and dust generation can significantly increase the likelihood of inhalation exposure.

While other routes of exposure, such as injection, ingestion, and absorption, can certainly occur in certain situations, they are generally less common compared to inhalation, particularly in occupational settings where airborne chemicals pose a risk to workers' health.
