Emergency overview: This material is not hazardous by OSHA Hazard Communication Definition. Signal Word(s): Harmful! Irritant! Main Hazards: Harmful by inhalation, in contact with skin, and if swallowed. Irritating to eyes, respiratory system and skin. Physical Health Hazards: Dry dust may form respirable particulates if disturbed. If this material gets into the eyes, it could be irritating. Material could be irritating if the dust is inhaled. Could also be irritating if skin is exposed to the dry powder. Physical state: Liquid Color: blue Odor: None Odor threshold: No data available Potential Health Effects: Routes of exposure: Eye contact, ingestion, skin contact Signs and Symptoms of Acute Exposure: This material if used properly, should not pose any kind of real hazard. If the material is used improperly, for example, if the dust is inhaled, it could be very irritating to the respiratory tract. Eye contact: Mechanical irritation is possible; can be irritant. Skin Contact: There may be irritation and redness at the site of contact. Ingestion: May be harmful if swallowed. Nausea and stomach pain may occur. There may be vomiting and diarrhea. Headaches or general malaise may result. May cause blueness around the mouth. Inhalation: Exposure may cause coughing or wheezing. May cause blueness around the mouth. Nausea and stomach pain may occur.
Take proper precautions to ensure your own health and safety before attempting to rescue and providing first aid. For specific information refer to the Emergency Overview in Section of this MSDS. Symptoms: Skin contact: There may be irritation and redness at the site of contact. An itchy rash may occur at the site of contact. Eye contact: There may be irritation and redness. Ingestion: Nausea and stomach pain may occur. There may be vomiting. Inhalation: Nausea and stomach pain may occur. Action: Skin Contact: Remove all contaminated clothes and footwear immediately unless stuck to skin. Drench the affected skin area with running water for ten minutes or longer if substance is still on skin. Transfer to hospital if there are burns or symptoms of poisoning. Eye Contact: Wash eyes with clean low-pressure water. Continue to rinse for 15 minutes. Seek medical advice for examination and possible further treatment of the affected eye(s). Ingestion: Do not induce vomiting. Wash out mouth with water. Seek emergency medical attention at once. Inhalation: Remove victim from further exposure ensuring your own safety first. If unconscious, and check for breathing and apply artificial respiration if necessary. If breathing becomes bubbly, have the casualty sit and provide oxygen if available.If unconscious and breathing is OK, place in the recovery position. If conscious, ensure the victim sits or lies down. Seem medical attention at once.
Extinguishing Media: Any suitable medium for extinguishing the supporting fire. Use water to keep fire-exposed containers cool. For fire specifically involving this product, use water spray, dry chemical powder, alcohol or polymer foam, or CO2 to extinguish the fire. Exposure Hazards: In combustion emits toxic fumes. Protection of Fire-Fighters: Protective Equipment/Clothing: Wear a NIOSH approved positive pressure self-contained breathing apparatus and firefighter turnout gear. This should be selected on the basis of the supporting fire. Avoid having the fumes come in contact with skin and eyes.
See Sections 8 and 13. Personal precautions: Do not attempt to take action without suitable protective clothing. Do not create dust so that there are air borne particulates that could be inhaled.
