Denver Drywall Dust: Construction Hiding Toxic Lung Harm?
By Franklin Everett ShawThe air in Denver, crisp and clean as it often is, can hide a silent danger lurking within the walls of older homes undergoing renovation. It’s not the altitude, but the dust – specifically, the dust from drywall. While seemingly innocuous, this dust can pose serious health risks, especially to your lungs. Ignoring proper mitigation can lead to long-term health problems, and in some cases, even legal battles.
Denver’s older housing stock, particularly in neighborhoods like Capitol Hill and Baker, often contains drywall installed decades ago. This drywall, when disturbed during remodeling, can release harmful particles into the air. The primary concern is crystalline silica, a common component of drywall compound. Inhaling crystalline silica can lead to silicosis, a debilitating and irreversible lung disease.
Silicosis scars the lungs, making it difficult to breathe. Symptoms can include shortness of breath, coughing, fatigue, and chest pain. The disease can progress even after exposure has stopped. Denver residents need to be particularly vigilant because silicosis can be misdiagnosed as other respiratory ailments common in the area, such as asthma or allergies.
But silicosis isn’t the only worry. Older drywall might also contain asbestos, a known carcinogen. While asbestos was phased out of drywall production in the late 1970s, many homes built before then still contain it. Disturbing asbestos-containing drywall releases microscopic fibers into the air, which, when inhaled, can cause mesothelioma, lung cancer, and asbestosis.
So, how can Denver homeowners protect themselves and their families during renovations? Here’s a step-by-step guide to proper dust mitigation:
Testing is Key: Before starting any demolition or renovation work on a home built before 1980, test the drywall for asbestos. Certified asbestos testing companies in Denver, such as ATC Environmental or CTL Thompson Materials Engineers, can collect samples and analyze them in a lab. This typically costs between $50 and $100 per sample. Don’t skip this step; it’s crucial for your health.
Containment is Crucial: Create a physical barrier between the work area and the rest of your home. Use heavy-duty plastic sheeting (at least 6 mil thick) and painter’s tape to seal off doorways, windows, and vents. Think of it like creating a negative pressure zone, similar to what hospitals use to contain infectious diseases.
Ventilation is Vital: Set up a high-efficiency particulate air (HEPA) filter to continuously clean the air in the work area. Position the filter to exhaust air outside, if possible. This helps remove dust particles and prevents them from circulating throughout your home. Consider renting a commercial-grade HEPA air scrubber from a local equipment rental company like Herc Rentals or Sunbelt Rentals.
Personal Protective Equipment (PPE) is Non-Negotiable: Wear a properly fitted N95 or P100 respirator mask at all times while working. These masks filter out at least 95% of airborne particles. Also, wear disposable coveralls, gloves, and eye protection to prevent dust from contacting your skin and eyes. Dispose of the coveralls and gloves after each use.
Wet Methods are Your Friend: Use wet methods to minimize dust generation. Lightly mist the drywall with water before cutting, sanding, or demolishing it. This helps to bind the dust particles together, preventing them from becoming airborne. A simple spray bottle filled with water works well for small areas.
HEPA Vacuuming is Essential: Use a HEPA vacuum to clean up dust and debris regularly. Ordinary vacuums can actually spread dust particles into the air. HEPA vacuums have filters that trap even the smallest particles. Vacuum all surfaces in the work area, including walls, floors, and ceilings.
Proper Disposal is Paramount: Dispose of drywall debris properly. Double-bag the debris in heavy-duty plastic bags and seal them tightly. Contact your local waste management company for specific disposal guidelines. In some cases, you may need to dispose of asbestos-containing materials at a designated hazardous waste facility.
Decontamination is Key: After the renovation is complete, thoroughly decontaminate the work area. Wipe down all surfaces with a damp cloth and HEPA vacuum again. Remove the plastic sheeting carefully, folding it inward to contain any remaining dust. Dispose of the sheeting properly.
Medical Monitoring is Recommended: If you suspect you have been exposed to drywall dust, especially if the drywall contained asbestos, consult with a medical professional. Dr. Anthony Gerber at National Jewish Health in Denver is a pulmonologist specializing in occupational lung diseases. Early detection and treatment are crucial for managing silicosis and asbestos-related illnesses.
Know Your Legal Rights: If you develop a health problem as a result of drywall dust exposure, you may have legal recourse. Contact a Denver-based attorney specializing in personal injury or workers’ compensation cases, such as Burg Simpson Eldredge Hersh & Jardine, P.C., or The Gilbert Law Group. They can advise you on your legal options and help you pursue compensation for your medical expenses, lost wages, and other damages.
A common mistake Denver homeowners make is underestimating the amount of dust generated during drywall work. Even seemingly small projects can release significant amounts of dust into the air. Another pitfall is failing to properly seal off the work area, allowing dust to spread throughout the home.
Finding contractors in Denver who prioritize dust control can be a challenge. Look for contractors who are certified by organizations like the EPA or the National Association of the Remodeling Industry (NARI). Ask potential contractors about their dust control procedures and request references from previous clients. Companies like High 5 Plumbing and Brothers Plumbing, Heating, and Electric often work with older homes and understand the importance of dust mitigation.
Ignoring the risks of drywall dust exposure is a gamble with your health. By following these steps, Denver residents can protect themselves and their families from the dangers of silicosis and asbestos-related diseases. Don’t let your dream renovation turn into a health nightmare. Take the necessary precautions and breathe easy.
