Health Hazard Data Routes of entry Inhalation, Skin and Eyes Effects of Exposure / Symptoms Inhalation causes increased respiration rate, headache, subtle physiological changes for upto 5% conc. And prolonged exposures. Higher concentrations can cause unconsciouness and death. Solid can cause cold contact burns. Liquid or cold gas cause freezing injury to skin or eyes similar to burn. Emergency Treatment Inhalation : Move the victim to fresh air area. Skin : Treat burns from contact with solid in the same way as frastbite. Eyes : Irrigate with plenty of water for 15 mins. Seek medical aid immediately.

Preventive Measures Personal Protective Equipment Avoid contact with liquid or Solid. Provide self-contained breathing apparatus in excessively high Co2 conc areas. For handling liquid or solid, wear face shield, or safety goggles, insulated gloves, long sleeved shirt, and trousers worn outside. Handling & Storage Precautions Keep in a dry cool place away from heat.
Emergency / First aid Measures FIRE - Fire Extinguishing Media Not flammable Special Procedure Unusual Hazards Keep the containers cool by spraying water if exposed to fire or heat. Containers may explode in fire. EXPOSURE - First Aid Measures Inhalation : Remove the victim to fresh air area. Skin : Treat burns from contact with solid in the same way as frostbite. Eyes : Irrigate with plenty of water for 15 mins. and immediately seek medical aid. Antidotes / Dosages Not available
Spills Steps to be taken Shut off leaks if without risk. Allow to evaporate slowly. Waste Disposal Method Allow the liquid or solid to evaporate under control.
Additional Information / References LCLo 10000 ppm / 1M (ihl-hmn). An asphyxiant. Contact of carbon dioxide snow with skin can cause burns. Dusts of Magnesissm, Zirconlsam, Titanium and some Magnesium. Aluminium alloys ignite and then explode in Co2 atmosphere. Several bulk metals will burn in Co2, atmosphere. Humans cannot breathe air containing more than 10% Co2 without losing consciousness.
