SECTION 2: Hazards identification

WARNING Toxic - Harmful by inhalation. (Contains crystalline silica) Respiratory Eye Protection Use proper engineering controls, work practices, and Personal Protective Equipment (PPE) to prevent exposure to dust. Read MSDS for details. Gloves (continued) Emergency Overview: Drywall is a sold material that is composed of paper covered gypsum board. The paper covering can be gray, green, brown, blue, or white while the internal gypsum board is an off-white color. Drywall is odorless. Drywall is not combustible or explosive. A single, short-term exposure to drywall dust presents little or no hazard.

Potential health effects

Eye Contact: Eye contact to airborne dust may cause immediate or delayed irritation or inflammation. Eye exposures require immediate first aid and medical attention to prevent significant damage to the eye. Skin Contact: Drywall dust may cause dry skin, discomfort, and irritation. Inhalation (acute): Breathing dust may cause nose, throat or lung irritation, including choking, depending on the degree of exposure. Inhalation (chronic): Risk of injury depends on duration and level of exposure. Silicosis: This product contains crystalline silica. Prolonged or repeated inhalation of respirable crystalline silica from this product can cause silicosis, a seriously disabling and fatal lung disease. See Note to Physicians in Section 4 for further information. This product contains mica. Prolonged and repeated inhalation of respirable mica dust may cause lung disease (pneumoconiosis). The extent and severity of lung injury depends on duration and level of exposure. Carcinogenicity: Crystalline silica is classified by IARC and NTP as a known human carcinogen. Autoimmune Some studies show that exposure to respirable crystalline silica (without silicosis) Disease: or that the disease silicosis may be associated with the increased incidence of several autoimmune disorders such as scleroderma (thickening of the skin), systemic lupus erythematosus, rheumatoid arthritis and diseases affecting the kidneys. Tuberculosis: Silicosis increases the risk of tuberculosis. Some studies show an increased incidence of chronic kidney disease and end- Renal Disease: stage renal disease in workers exposed to respirable crystalline silica. Ingestion: Do not ingest drywall. Ingestion of small quantities of drywall is not known to be harmful; ingesting large quantities can cause intestinal distress. Medical Conditions Individuals with lung disease (e.g. bronchitis, emphysema, COPD, pulmonary Aggravated by Exposure: disease) can be aggravated by exposure.
