CRS Indicating Oxygen-Removing Purifier

SECTION 2: Hazards identification

Do not open cartridge. Contents may generate heat in contact with air or water. Emergency Overview Appearance (contents of cartridge): Black or gray powder; green powder becomes gray on exposure to air. Immediate concerns: May cause burns. Irritant - Dust may irritate mucous membranes, eyes, lungs and skin. Harmful if swallowed or inhaled. Inhaling dust can cause irritation of the upper repiratory tract, and my lead to "metal fume fever", a flu-like condition. Long term exposure by inhaling or swallowing can affect the central nervous system or lungs. Sodium oxide reacts violently with water or moisture. Reducer in the active state; when depleted by reaction with oxygen becomes an oxidizer.

Principle Routes of Exposure

Inhalation (breathing), ingestion (swallowing), eyes, skin

Potential health effects

Eyes: Product is abrasive to the eyes and may cause irritation. Skin: Product is abrasive to skin and may cause irritation. Prolonged skin exposure to trivalent chromium compounds may cause dermatitius. May cause sensitization by skin contact. Ingestion: May result in G.I. disturbances and possible hemorrhage. Renal failure may occur after a few days. Methemoglobinemia has also been reported. Long term exposure by swallowing can affect the central nervous system. Inhalation: Dust can cause irritation of the upper respiratory tract and may lead to "metal fume fever", a flu-like condition. Inhalation of magnesium oxide fumes have been known to produce leukocytosis. Chronic exposure to manganese dioxide by breathing low levels of dust or fume for a long time can result in disease of the central nervous system similar to Parkinsonism. Signs and Symptoms of Overexposure Eyes: Irritation from mechanical abrasion. Skin: Irritation from mechanical abrasion. Ingestion: May produce metallic taste, severe nausea, vomiting, abdominal pain, diarrhea and hemolysis. Inhalation: Flu-like symptoms may include fever, chills, nausea and vomiting, muscular aches, weakness and fatigue. Breathing high concentration of dust or fume may produce metallic taste, dryness and irritation of the throat, coughing, sneezing, and bronchitis. ________________________________________________________________________________________ DISCLAIMER: This Safety Data Sheet is offered without charge to the clients of Chromatography Research Supplies, Inc.

Medical Conditions Generally Aggravated by Exposure

Eye, skin, and respiratory diseases or disorders would be aggravated by repeated or prolonged exposure to the dust or fume from this chemical. Iron deficiency may increase susceptibility to manganese poisoning.
