GS-42 Compliance: Explaining the New Air Filter Regulations for Construction and Demolition
GS-42 Compliance: A New Era of Air Filter Regulations in Construction and Demolition
Key Takeaways:
- The OSHA’s revised Respirable Crystalline Silica Standard (29 CFR 1910.1053) for construction and demolition activities requires employers to implement new air filter systems to reduce silica exposure
- GS-42, a new air filter standard, meets the OSHA’s regulations and ensures a safe and healthy work environment for construction and demolition workers
- Compliance with GS-42 is mandatory for all construction and demolition projects, with deadlines for implementation and compliance in place
The Problem: Silica Exposure in Construction and Demolition
Crystalline silica is a common mineral found in many construction materials, including concrete, mortar, and masonry. When workers perform tasks like cutting, crushing, or drilling these materials, silica particles become airborne, posing serious respiratory health risks. Long-term exposure to silica can lead to silicosis, lung cancer, and other serious health issues.
The Solution: GS-42 Compliance
In 2016, the Occupational Safety and Health Administration (OSHA) introduced a new standard to reduce respirable crystalline silica exposure in the construction and demolition industries. The standard (29 CFR 1910.1053) requires employers to implement controls to limit worker exposure to 25 μg/m3 for an 8-hour time-weighted average (TWA).
What is GS-42?
GS-42, a new air filter standard, is designed to meet and exceed the OSHA’s silica exposure limits. Developed by the Air Filtration industry, GS-42 is a voluntary, industry-wide standard that ensures high-efficiency air filters meet the OSHA’s regulatory requirements. By specifying a minimum 42% Arrestance (a measure of filter efficiency), GS-42 certifies air filters that can effectively capture 42% of particles 0.5*10^-5 cm (0.5 μm) or larger, effectively reducing silica exposure and protecting worker health.
Applications and Compliance
GS-42 compliance is mandatory for all construction and demolition projects, including:
- Construction sites (e.g., building construction, renovation, or repair)
- Demolition sites (e.g., deconstruction, wrecking, or dismantling)
- Allied trades, such as excavation, drilling, or blasting
- Disruption of materials (e.g., drilling, grinding, or cutting) containing silica
To ensure compliance, employers must:
- Conduct a hazard assessment: Identify potential silica exposure areas and tasks
- Implement controls: Use personal protective equipment (PPE), vacuum systems, and HEPA-filtered equipment
- Use certified air filters: Install GS-42-compliant air filters in HVAC systems, local exhaust ventilation (LEV) systems, and powered air-purifying respirators (PAPRs)
- Train workers: Educate employees on silica risks, control measures, and proper PPE use
Conclusion
GS-42 compliance is a critical step in protecting the health and safety of construction and demolition workers. By understanding the new air filter regulations and implementing GS-42-compliant solutions, employers can ensure a safe and healthy work environment, reducing the risks associated with silica exposure and preventing occupational illnesses.
