What should not be used to suspend cylinders?

Ropes, chains, or slings are not suitable for suspending gas cylinders because they may not provide a secure or stable support. Gas cylinders are heavy and should be handled with equipment designed specifically for lifting and securing heavy objects. Using materials like ropes or chains can lead to improper support, risking the cylinder falling or rolling, which can cause serious accidents or injuries.

In contrast, items like straps or belts are typically designed to secure loads and can offer the necessary strength and stability to safely hold gas cylinders in place. Hoses or cables also do not provide adequate support for the weight and balance required for cylinders. Planks or beams can be used in certain scenarios for stability, provided they are appropriately secured to prevent any movement or shifting of the cylinders. Hence, the use of robust and specialized equipment is essential in handling these heavy and sometimes hazardous materials safely.
