Exposure limits refer specifically to the maximum allowable concentration of a hazardous substance in the air that workers are exposed to over a specified time period. These limits are crucial for ensuring workplace safety and are established based on health risk assessments, scientific studies, and recommendations from occupational health organizations. They are designed to minimize the risk of adverse health effects resulting from inhalation or contact with hazardous materials.

By defining exposure limits in this way, employers can implement necessary controls and protective measures to maintain concentrations below these thresholds. This ultimately serves to protect employees' health and welfare in the working environment. Understanding exposure limits is vital for hazardous materials management, as it informs safety protocols, monitoring practices, and compliance with regulations designed to manage chemical exposure in various occupational settings.
