UN 1013 — Carbon dioxide, compressed

Carbon dioxide, compressed, is a colorless, odorless gas at room temperature, classified as a compressed gas under the DOT class 2. It is widely used in industrial processes, food and beverage production, and medical applications. First responders may encounter carbon dioxide, compressed, in various scenarios, including transportation accidents, industrial leaks, or medical emergencies. The scale of production and transport of carbon dioxide, compressed, is significant, with millions of tons being produced and transported annually. As a result, first responders must be prepared to handle emergencies involving this substance. Carbon dioxide, compressed, is a critical component in many industrial processes, and its release can have significant consequences. The widespread use of carbon dioxide, compressed, in various industries increases the likelihood of first responders encountering it during emergency situations.

Hazard overview: Carbon dioxide vapors can cause dizziness or asphyxiation without warning, and the gas can spread along the ground, making it a hazardous substance in confined areas. Prolonged exposure to high concentrations can also cause respiratory problems.

Response guidance: In the event of a spill or leak, first responders should ensure adequate ventilation and treat the area as a simple asphyxiant in confined spaces. The correct suppression agent for carbon dioxide, compressed, is not applicable, as the substance is non-flammable. However, ventilation can be used to disperse the gas, and combustible materials should be avoided. Decontamination procedures should be followed, and CHEMTREC should be contacted in the event of a spill or leak. First responders should also be aware of the potential for carbon dioxide, compressed, to accumulate in low-lying areas or confined spaces, increasing the risk of asphyxiation.

Firefighter training notes: First responders should receive training on the hazards associated with carbon dioxide, compressed, including its ability to displace oxygen and cause asphyxiation. A known tactical error for this chemical class is the failure to recognize the potential for carbon dioxide, compressed, to accumulate in low-lying areas or confined spaces, increasing the risk of asphyxiation. ICS position needs and mutual aid criteria should also be established to ensure a coordinated response to emergencies involving carbon dioxide, compressed. First responders should be aware of the potential for carbon dioxide, compressed, to be involved in a wide range of emergency scenarios, from industrial accidents to medical emergencies.

Regulatory context: Carbon dioxide, compressed, is classified as a DOT class 2 substance, with a packing group not applicable. The OSHA PEL/TLV for carbon dioxide, compressed, is 5,000 ppm (0.5%) as an 8-hour TWA, and the substance is subject to various regulations and guidelines, including those related to transportation, storage, and handling. First responders should be aware of the regulatory requirements for carbon dioxide, compressed, and follow established procedures for handling and responding to emergencies involving this substance.

Storage & handling: Carbon dioxide, compressed, should be stored in a well-ventilated area, away from incompatible materials such as heat sources or ignition sources. The temperature limit for storage is not established, but the substance should be kept away from heat sources or ignition sources. The top 3 incompatible materials for carbon dioxide, compressed, are heat sources, ignition sources, and oxidizable materials. The ventilation standard for storage is to provide adequate ventilation to prevent the accumulation of carbon dioxide, compressed, in low-lying areas or confined spaces.
