Using compressed gas in welding presents significant hazards, particularly the risk of explosion or fire if the gases are not handled properly. Compressed gases, such as oxygen and acetylene, are highly flammable and can create explosive environments when mixed improperly or when there are leaks. The potential for these gases to ignite presents a danger not only during the welding process but also when transporting and storing these gas cylinders. Proper storage, ventilation, and regular checks for leaks are crucial safety measures that must be observed to mitigate these risks.

Understanding the behavior of these gases under pressure and their reactivity is essential for any welding professional. This knowledge assists in ensuring safety protocols are strictly adhered to while working with or around compressed gases. While other hazards like exposure to harmful fumes or high temperatures are relevant in welding, the specific dynamics of working with compressed gases make the risk of explosion or fire a particularly critical concern that must be emphasized and managed effectively.
