Permissible Exposure Limits in the Construction Industry
Permissible Exposure Limits (PELs) are regulatory thresholds set by OSHA to protect workers from harmful levels of exposure to hazardous substances during workplace accidents in Oregon. These limits define the maximum amount of a chemical or substance a worker can be exposed to over a specific period, typically an eight-hour workday. By adhering to PELs, construction sites can reduce the risk of long-term health issues, ensuring a safer work environment for all employees.
Understanding Permissible Exposure Limits (PELs)
OSHA’s standards for PELs vary depending on the substance and its associated health risks. For example, substances like lead, silica, and asbestos have strict PELs due to their potential to cause severe health problems and construction injuries.
Common Hazardous Substances on Construction Sites
Construction sites often expose workers to hazardous substances that can lead to severe health problems if not properly managed. These materials include toxic chemicals, dust particles, and other harmful elements commonly encountered during construction activities.
Lead
Lead exposure on construction sites can have serious health consequences, including neurological damage and kidney problems. Workers often encounter lead in materials such as paint, pipes, and other construction components, making it essential to monitor exposure levels closely. OSHA has set a permissible exposure limit (PEL) of 50 micrograms per cubic meter of air over an 8-hour period per Appendix B to § 1910.1025 to protect workers from these risks.
Silica
Silica exposure is a significant concern for construction workers, as it can lead to severe respiratory illnesses, including silicosis and lung cancer. Workers are commonly exposed to silica when cutting, grinding, or drilling concrete, brick, or stone materials.
To protect against silica exposure, employers must implement control measures such as using water systems to suppress dust and providing appropriate personal protective equipment (PPE) like respirators. OSHA has set a permissible exposure limit (PEL) of 50 micrograms per cubic meter of air over an 8-hour period per 1910.1053(c) to protect workers from these risks.
Asbestos
Asbestos exposure on construction sites poses serious health risks, including mesothelioma, asbestosis, and lung cancer. Workers may encounter asbestos during demolition or renovation projects involving older buildings, as asbestos was commonly used in construction materials like insulation, roofing, and flooring. OSHA mandates a permissible exposure limit (PEL) of 0.1 fibers per cubic centimeter of air over an 8-hour workday.
Employer Responsibilities for Managing PELs
Monitoring and Testing
Employers must regularly monitor and test air quality on construction sites to identify hazardous substance levels. Techniques such as air sampling and direct-reading instruments help detect substances like silica, lead, and asbestos that may exceed PELs. Once levels are identified, employers can take immediate action to address dangerous conditions, ensuring the worksite meets OSHA standards.
Engineering Controls and PPE
Installing proper ventilation systems, using water sprays to reduce dust, and enclosing hazardous processes are effective strategies for minimizing risks. Workers should have access to properly fitted respirators, gloves, and eye protection to protect against harmful substances.
