Section 2: Composition and Information on Ingredients IngredientCAS NumberPercentACGIH (TWA)OSHA (PEL) Title compound11110-52-4100%0.025mg/m31mg/10m3 Section 3: Hazards Identification The alloy rapidly forms corrosive alkali hydroxide with evolution of heat. Severe thermal and chemical burns Emergency Overview: will result. Toxic by inhalation, in contact with skin and if swallowed. Danger of cumulative effects. Primary Routes of Exposure:Contact with skin and eyes. Vapor inhalation. Eye Contact:Severe thermal burns, corrosion and ulceration of the eyes may occur on direct contact. Skin Contact:Severe thermal burns, corrosion and ulceration of the skin may occur on direct contact. Inhalation:Inhalation of dust will severely irritate the nasal cavity and respiratory tract. Mercury vapor is toxic Ingestion:Toxic if swallowed. Ingestion will cause burns and perforations of the gastrointestinal tract. Acute Health Affects:Corrosive to skin, eyes and respiratory tract. Toxic by inhalation, in contact with skin and if swallowed. Danger of cumulative effects. The chronic effects of mercury poisoning include stomatitis, tremors, psychic Chronic Health Affects:disturbances, excessive salivation, and pain on chewing. Other effects include loss of memory, insomnia, lack of confidence, irritability and depression. NTP:No IARC:No OSHA:No SECTION 4: First Aid Measures Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need Eye Exposure: assistance in keeping their eye lids open. Get immediate medical attention. Wash the affected area with water for at least 15 minutes. Remove contaminated clothes if necessary. Seek Skin Exposure: medical assistance if irritation persists. Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty Inhalation: in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance.
