Section V. Toxicological Properties
SODIUM DICHROMATE page 2/4
Use flooding quantities of water. Wear adequate personal protection to prevent contact with material or its combustion products.
Self contained breathing apparatus with a full facepiece operated in a pressure demand or other positive pressure mode. Cool
containing vessels with flooding quantities of water until well after fire is out. Move containing vessels from fire if without risk.
Powerful oxidizing agent; may ignite oxidizable materials. Contributes to combustion of other materials. Contact with
other material may cause fire and/or explosion. Contact with other material may form shock, heat or friction sensitive
mixtures. Container explosion may occur under fire conditions or when heated. Emits toxic fumes under fire conditions.
Routes of entry Inhalation and ingestion. Eye contact. Skin contact. Skin absorption.
Effects of Acute
Exposure
Skin
Inhalation
Ingestion
Chromium and sodium oxides.
May be fatal by ingestion, inhalation or skin absorption. Severe irritant! Potentially harmful amounts can cause damage to
kidneys, liver, blood, lungs, eyes, skin, respiratory system, and/or bone marrow.
Eye Causes conjunctivitis, severe irritation or burns and loss of vision. May cause permanent damage.
Causes severe irritation. Prolonged exposure may result in skin burns and ulcerations. Contact with broken skin may lead to
formation of firmly marginated "chrome sores". Massive overexposure could lead to damage to the kidneys, liver, blood, and/or
bone marrow, kidney failure and death. A strong sensitizer which may cause skin rash.
Inhalation of dust or mist may irritate the nasal septum and respiratory tract. Destructive to tissues of mucous
membranes. Prolonged or repeated exposure may cause ulceration and perforation of the nasal septum. May cause
headache, nausea, vomiting, chemical pneumonitis and pulmonary edema. May cause sensitization by inhalation. Can
cause liver, kidney, and lung damage.
Burns in mouth, pharynx and gastrointestinal tract (can cause severe tissue destruction.). May cause vomiting, nausea,
abdominal pain, fever, diarrhea, coma, bleeding and/or tissue ulceration, gastroentritis, toxic nephritis with glycosuria,
blood and bone marrow damage, liver and kidney failure, peripheral vascular collapse and death. Estimated lethal dose is
5 g.
