Sodium Hydrosulfide

CAS RN:16721-80-5

Range of Toxicity

A) Concentrations of 50 to 100 ppm are associated with mild toxicity manifesting as respiratory tract irritation while concentrations greater than 500 ppm are usually associated with the loss of consciousness and death.
B) At an airborne concentration of 0.05 ppm, hydrogen sulfide produces a characteristic odor of rotten eggs. The distinctive rotten egg odor cannot be detected at concentrations above 150 ppm.
C) Exposure to greater than 500 ppm results in severe toxicity and death. Respiratory paralysis and death may be noted within 30 to 60 minutes. At 800 to 1000 ppm, death may be nearly immediate after 1 or more breaths.

A) LIQUID CORROSIVES - With highly concentrated liquids (30% sodium hydroxide) esophageal burns may occur in up to 100% of patients, even after accidental ingestion.
B) Serious burns are less likely if the pH is less than 11.5. Injury is greater with large exposures and high concentrations.
C) More recent series of caustic ingestions (mixed liquid and solid) in children report incidences of significant esophageal burns from 5% to 35%. Adults with deliberate ingestions are more likely to develop significant esophageal burns (30% to 80%).
D) LOW PHOSPHATE DETERGENTS and electric dishwasher soaps may result in oral and esophageal burns.
