What precaution should be taken when handling CO₂ extinguishers?

When handling CO₂ extinguishers, wearing gloves and holding the extinguisher upright ensures safety and proper functioning. CO₂ extinguishers discharge carbon dioxide in a very cold form, and the freezing temperatures can cause skin damage if it comes into contact with bare skin. Gloves provide insulation, protecting the user from cold burns.

Holding the extinguisher upright is crucial because CO₂ is stored as a liquid and needs to be released in a controlled manner; this position ensures that the CO₂ is expelled effectively and safely when the handle is pressed. Ensuring a proper grip and position also enhances the user's control over the extinguisher while extinguishing a fire, making the operation smoother and more effective, keeping both the user and others safe during the firefighting process.

Other precautions, while also important, do not primarily focus on the safe handling aspect as directly as the use of gloves and maintaining an upright position.
