What potential hazards are associated with dry ice?

Dry ice, which is the solid form of carbon dioxide, poses several hazards that can be categorized primarily into frostbite, asphyxiation, and the potential for explosions.

Frostbite can occur upon direct contact with dry ice, as it is extremely cold at about -78.5 degrees Celsius (-109.3 degrees Fahrenheit). This low temperature can cause freezing of skin and injury similar to burns, resulting in tissue damage if contact is prolonged.

Asphyxiation is a significant risk because dry ice sublimates into carbon dioxide gas. In poorly ventilated spaces, this buildup of carbon dioxide can displace oxygen in the air, leading to an unsafe environment where there may not be enough oxygen for breathing, potentially causing suffocation.

The potential for explosions arises when dry ice is sealed in a container. As the dry ice sublimates to gas, the pressure inside the container can increase significantly. If the pressure becomes too high and the container can no longer withstand it, an explosion may occur, leading to injury or damage.

Overall, these hazards highlight the importance of handling dry ice with caution, ensuring appropriate ventilation, and using protective gear to prevent skin contact. The other options do not accurately represent the risks associated with dry ice, thereby supporting the
