Name one common respiratory hazard in construction.

Silica dust is a well-recognized respiratory hazard in the construction industry, primarily arising from activities such as cutting, grinding, or drilling into materials that contain silica, including concrete, stone, and masonry. When these materials are disturbed, tiny silica particles become airborne and can be inhaled, leading to serious health conditions such as silicosis, chronic obstructive pulmonary disease (COPD), and lung cancer. The Occupational Safety and Health Administration (OSHA) has established specific regulations and exposure limits for silica to protect workers, highlighting its significance as a hazardous substance in construction.

While other options like asbestos fibers and coal dust also represent serious respiratory hazards, silica dust is more frequently encountered in construction settings due to the prevalence of silica-containing materials. Sand dust is less specific, and although it can contribute to respiratory issues, its connection to silica is more pivotal when considering common aerial nuisances that workers face in construction.
