Principle Routes of Exposure

Eyes and inhalation.

Medical Conditions Generally Aggravated by Exposure

Sensitive individuals can experience skin irritation from repeated exposure to sulfur dust. Allergenic responses can occur. Chronic Exposure: Prolonged overexposure to sulfur dust can produce possible skin sensitization and permanent eye damage (clouding of the lens and chronic irritation). Prolonged inhalation can cause irritation of mucous membranes. May cause central nervous system effects. Eye Contact: Sulfur dust is an eye irritant. Skin Contact: May cause skin irritation and possible burns. Skin with existing skin lesions will experience aggravated irritation. Ingestion: Considered essentially non-toxic by ingestion. Ingested sulfur is converted to sulfides in the gastrointestinal tract, and ingestion of 10 to 20 grams has caused irritation of the gastrointestinal tract and renal injury. Individuals with allergies to sulfide drugs may have an allergic reaction. Swallowing large amounts may cause nausea and vomiting. Inhalation: Prolonged inhalation may cause irritation of the respiratory tract. Breathing of dust may aggravate asthma and other pulmonary diseases. Individuals with allergies to sulfide drugs may have an allergic reaction.
