The maximum airborne concentration limit for arsenic set by NIOSH over a short time is established to protect workers from the acute health effects associated with arsenic exposure. NIOSH has identified that exposure to arsenic can lead to serious health issues, including respiratory problems and potential skin and internal organ damage, when concentrations exceed a certain level.

The limit specified by NIOSH is 2 μg/m³ over a short time frame. This concentration is designed to ensure that any potential occupational exposure remains within a range that is considered safe and manageable to minimize the risk of acute toxicity. It reflects an understanding of the potency of arsenic as a hazardous substance and emphasizes the need for stringent controls in occupational environments where exposure is possible.

Maintaining exposure below this limit is critical for worker safety and aligns with NIOSH's mission to prevent work-related injury and illness through scientific research and guidance on occupational health standards.
