What does 'short duration' mean when working with asbestos?

The term 'short duration' when working with asbestos specifically refers to activities that are brief and controlled, minimizing potential exposure to hazardous materials. The definition given in the correct answer indicates a time limit of less than one hour for a single worker, or an aggregate of less than two hours for multiple workers. This limitation is crucial, as shorter exposure times significantly reduce the risk of inhaling asbestos fibers, which pose serious health risks.

When dealing with hazardous materials like asbestos, time is a critical factor in managing health risks. By defining 'short duration' in this manner, it helps to establish clear guidelines for safety precautions and the necessary protective measures that should be in place during such work. Adhering to these defined time limits allows for effective risk management and compliance with health and safety regulations.
