Why is gypsum toxic?

Gypsum Poisoning. Anaerobic bacteria are common bacterium that can exist in gypsum that was NOT properly processed. When the gypsum becomes damp, the bacteria works with the oxygen in the water and converts the calcium sulphate into calcium sulphide, which produces a poisonous gas called hydrogen sulphide.

Harmful Dust

Cutting drywall and sanding dried joint compound can expose you to harmful chemicals in the dust. The dust can irritate your respiratory system and cause persistent coughing or difficulty breathing. If the drywall contains silica, long-term exposure can cause cancer or lung diseases.

What happens if you inhale gypsum?

Over time, breathing the dust from drywall joint compounds may cause persistent throat and airway irritation, coughing, phlegm production, and breathing difficulties similar to asthma. Smokers or workers with sinus or respiratory conditions may risk even worse health problems.

Is all drywall toxic?

To answer your question in short: drywall dust is not toxic to the body in smaller amounts. This means it will not cause any long-term diseases. However, it can irritate parts of the body, like the eyes and throat. This is because it is made of a chemical known as gypsum (calcium sulfate dihydrate).

How do humans use gypsum?

Crude gypsum is used as a fluxing agent, fertilizer, filler in paper and textiles, and retarder in portland cement. About three-fourths of the total production is calcined for use as plaster of paris and as building materials in plaster, Keene's cement, board products, and tiles and blocks.

Drywall can release sulfur dioxide gas when burned, which is poisonous to both humans and the atmosphere.

Can you get silicosis from drywall dust?

When drywall is sanded, crystalline silica and mica is released into the air as dust. These minerals are extremely dangerous to the lungs. When they are inhaled, they are embedded in lung tissue. The lung tissue develops fiber nodules and scarring around the silica particles; this is known as silicosis.
