What is OSHA's current Excursion Limit for asbestos in the construction industry?

  1. 0.3 f/cc

  2. 1.0 f/cc

  3. 0.25 f/cc

  4. 0.6 f/cc

The correct answer is: 0.3 f/cc

OSHA's current Excursion Limit for asbestos in the construction industry is set at 0.3 fibers per cubic centimeter (f/cc) of air for any 30-minute period. This limit is designed to protect workers from excessive exposure to asbestos, a hazardous material known to cause serious health issues such as asbestosis and mesothelioma. Setting the excursion limit at this level reflects a balance between ensuring worker safety and the practicalities of asbestos-related work in construction environments. This limit allows for short-term exposures that may fluctuate during specific tasks but establishes a maximum threshold to help mitigate health risks. The other options represent different concentration levels that do not align with OSHA's established standard for short-term exposure. Understanding these limits is crucial for compliance and ensuring a safe workplace for those who may be exposed to asbestos fibers during construction activities.
