The OSHA silica standard for drywall restricts permissible exposure limits (PELs) to 50 micrograms per cubic feet of air over an 8-hour shift.
Controls. A recent NIOSH Health Hazard Evaluation (HHE) found that drywall sanders were exposed to as much as 10 times the permissible exposure limit (PEL) of 15 mg/m3 for total dust set by the Occupational Safety and Health Administration (OSHA).
The new silica dust safety regulations reduce the permissible exposure limit to 50 µg/m3, or lower, on a weighted average over an 8-hour period. To reduce the permissible exposure limit, OSHA's regulation states that silica dust collection vacuums must contain a filter with 99.00% efficiency or greater.
When you inhale drywall dust, your body doesn't really have a way to expel it again. It could sit in the lungs for decades, potentially causing a condition called interstitial lung disease. This occurs when fine particles or dust build up in the lungs.
Drywall and plaster dust will ruin a home vacuum, because the particles are too fine for the filters and will clog up the innards of the machine, and blow back out into your house again. They also don't do your little lungs any good. Wear a mask when you are working on it.
To effectively clean drywall dust before painting, use a vacuum with a HEPA filter to thoroughly remove any loose dust particles from the drywall surfaces. Then, wipe down the surfaces with a damp cloth to remove any remaining dust.
Yes, air purifiers play a big role in cutting down on construction dust and debris while projects are taking place in the surrounding area.
Lungs are self-cleaning organs that will begin to heal themselves once they are no longer exposed to pollutants. The best way to ensure your lungs are healthy is by avoiding harmful toxins like cigarette smoke, vaping and air pollution, as well as getting regular exercise and eating well.
Even after thoroughly dusting and cleaning, some drywall dust may still linger in the air. Consider using an air purifier equipped with a HEPA filter to capture these airborne particles.
Whether you're sanding drywall, wood or metal surfaces, reach for the 3M™ Performance Particulate Respirator 8210 for Paint Prep. This N95 respirator features Advanced Electrostatic Media that enhances the capture of airborne particles while allowing for easy breathing.
Gypsum can irritate mucus membranes and the respiratory system. Talc or talcum powder can irritate the respiratory system, damage the lungs, and can contribute to the development of cancer. Exposure to powdered mica can lead to fibrosis of the lungs and long-term respiratory difficulties.
Reduce drywall dust by sanding with a drywall vacuum sander. The drywall vacuum sander is a hose attached to your wet-dry shop vacuum. On one end is the sander, a special grid-like implement that sucks the drywall dust away and down through the hose. At the other end of the hose is a bucket of water.
Can dust from construction make you sick? Yes, dust from construction can make you sick. It often contains harmful particles, such as silica, asbestos, and lead, which can cause respiratory problems if inhaled. Symptoms can include coughing, wheezing, shortness of breath, and in severe cases, even lung disease.
To avoid problems, begin cleaning the dust when it's dry before proceeding to damp methods and always keep a dust mask on: Lightly brush the dust off the walls with a soft broom or hand brush. Move slowly from top to bottom. Sweep the dust from the floor before the next step.
Symptoms may include skin rashes, eye irritation, runny nose, sneezing, and even respiratory issues. This is often caused by an allergic reaction to substances in the drywall, such as dust, mold, or gypsum.
Given the factors mentioned above, determining an exact settling time for construction dust can be challenging. However, as a general guideline, most construction dust begins to settle within 48 to 72 hours after work has ceased.
To help drywall dust move outside, house cleaning professional Raymond Chiu recommends that you “open the windows to allow for ventilation.” Place box fans in the windows so they blow the air out of the room, and tape plastic sheeting around the fans and window frames to seal off the area.
Hang plastic sheeting.
Plastic sheeting helps keep the dirt and dust in the work area. It also works well for creating walls to protect other areas of your home. We used it to protect our storage area and the area where our water heater and furnace are located.
Dust buildup can cause serious health problems, according to Johns Hopkins Hospital lung expert Dr. Panagis Galiatsatos, including serious lung infections and in rare cases, even death. “A good inhalation of dust could be life threatening depending on someone's asthma exacerbation,” Galiatsatos said.
These diseases, caused by dust inhalation, are often described as work-related. They include diseases like asbestos-related conditions. Silicosis is a work-related lung disease — you get it because you're breathing in silica crystals at your job. You can't cure or reverse silicosis, but your providers can treat it.
While there are many ways to clean drywall dust, good old H20 is the best. Dust absorbs the water, and the dust becomes weighed down and unable to dissipate into the atmosphere. After spraying the dust, you can use a broom or vacuum to remove it without fear of it floating into the air.
Air Circulation Opening windows and blowing air out the doors and windows with fans, both during construction and after, can help clear dust that is airborne and bring in fresh air. Dust particles can be rough on lungs, so removing dust that is floating around is beneficial.
This can be caused by a hole in the filter, the filter not being properly installed, or the dust being too fine for the filter. If the dust is too fine, you need to upgrade to a filter capable of catching the dust and dirt you are cleaning up.
