What is a poor handling or storage practice for gases?

Storing cylinders in nonventilated areas is identified as a poor handling or storage practice for gases due to the potential hazards it presents. Nonventilated spaces can lead to the accumulation of gases, which may increase the risk of fire, explosion, or exposure to toxic substances. Proper ventilation is crucial for safely managing gas cylinders, as it enables the dispersal of any leaking or released gases, thereby minimizing danger to personnel and the environment.

In contrast, maintaining well-ventilated areas, securing cylinders in place, and labeling all cylinders correctly are all essential best practices in handling and storing gases. They contribute to safety by ensuring that any potential risks are mitigated through appropriate measures.
