How must compressed gas cylinders be secured?

1. In a horizontal position

2. In a vertical position

3. In an open area

4. In water

The correct answer is: In a vertical position

Compressed gas cylinders must be secured in a vertical position to ensure safety and stability. When stored vertically, cylinders can be properly secured to prevent them from tipping over, which reduces the risk of accidents, leaks, or damage to the valve. The upright position also facilitates easier handling and transportation, allowing for better access to the cylinder’s valve and reducing the likelihood of improper use. Storing cylinders in a horizontal position can create hazards, as they can roll or shift, potentially leading to damage and accidents. Keeping them in an open area does not provide adequate safety measures against falling or tipping over, and placing them in water could be dangerous, as it would not allow for safe retrieval or could introduce rust and corrosion concerns. Therefore, securing compressed gas cylinders vertically is the established safety protocol that helps minimize risks in various environments, particularly in construction and industrial settings.
