SECTION 2: Hazards identification

Emergency Overview

Appearance/Odor

Brown to black. Viscous liquid. Hydrocarbon.

Health hazards

Hydrogen sulphide is highly toxic and may be fatal if inhaled. May cause cancer. Safety Hazards : Combustible liquid. Hydrogen sulphide (H2S), an extremely flammable and toxic gas, and other hazardous vapours may evolve and collect in the headspace of storage tanks, transport vessels and other enclosed containers. Electrostatic charges may be generated during pumping. Electrostatic discharge may cause fire. Inhalation : Hydrogen sulphide is highly toxic and may be fatal if inhaled.Hydrogen sulphide (H2S), an extremely flammable and toxic gas, and other hazardous vapours may evolve and collect in the headspace of storage tanks, transport vessels and other enclosed containers.May dull the sense of smell, so do not rely on odour as an indication of hazard. Skin Contact : Repeated exposure may cause skin dryness or cracking. Prolonged or repeated skin contact without proper cleaning can clog the pores of the skin resulting in disorders such as oil acne/folliculitis. Eye Contact : May cause slight irritation to eyes. Ingestion : Low toxicity if swallowed.

Environmental hazards

Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment. : Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment.

Further information

May cause cancer. Signs and Symptoms : H2S has a broad range of effects dependent on the airborne concentration and length of exposure: 0.02 ppm odour threshold, smell of rotten eggs; 10 ppm eye and respiratory tract irritation; 100 ppm coughing, headache, dizziness, nausea, eye irritation, loss of sense of smell in minutes; 200 ppm potential for pulmonary oedema after >20-30 minutes; 500 ppm loss of consciousness after short exposures, potential for respiratory arrest; >1000ppm immediate loss of consciousness, may lead rapidly to death, prompt cardiopulmonary resuscitation may be required. Do not depend on sense of smell for warning. H2S causes rapid olfactory fatigue (deadens sense of smell). There is no evidence that H2S will accumulate in the body tissue after repeated exposure. Oil acne/folliculitis signs and symptoms may include formation of black pustules and spots on the skin of exposed areas. Defatting dermatitis signs and symptoms may include a burning sensation and/or a dried/cracked appearance.
