What is required for gas cylinders in terms of safety precautions?

1. They must be painted bright colors

2. They must be chained or secured at all times

3. They must be stored in a cool area

4. They should not be moved often

The correct answer is: They must be chained or secured at all times

Gas cylinders must be chained or secured at all times to prevent them from tipping over. When cylinders fall, there is a significant risk of the valve breaking off, which can create a highly dangerous situation. A ruptured cylinder can turn into a projectile, causing injuries or damage to surrounding areas. Securing cylinders reduces this risk and ensures they remain stable during transport and storage. While other options may seem relevant to safety in specific contexts—such as storing cylinders in a cool area to prevent pressure buildup or having them painted bright colors for easy visibility—these do not address the paramount safety concern of preventing falls, which can lead to catastrophic incidents. Therefore, securing cylinders is a critical and universally applicable safety measure that is emphasized in safety standards and guidelines.
