When working with gas cylinders, securing the cylinders upright and using protective caps is crucial for numerous safety reasons. Keeping the cylinders upright prevents them from tipping over, which could lead to leaks or damage. This stability is particularly important given the high pressures contained within gas cylinders, as falling over could cause the cylinder to become a projectile or lead to exposure to hazardous gases.

Using protective caps is equally important because these caps prevent the valve from being damaged, which could also lead to leaks. In the case of pressurized gases, a leaking cylinder could create dangerous situations, including fire hazards or exposure to toxic substances. Thus, securing the cylinders and ensuring their valves are well protected is a fundamental safety practice in handling these potentially dangerous materials.

While other practices may seem significant, they do not adhere to the best safety measures for working with gas cylinders. For instance, storing them in direct sunlight can lead to heat buildup and increased pressure within the cylinder, which is dangerous. Providing a flame source near the cylinders can create a high-risk environment, especially for flammable gases. Transporting cylinders horizontally is also unsafe as it can lead to ruptures or valve damage.
