What is located at the top and bottom of acetylene cylinders to prevent explosions?

Safety fuse plugs are specifically designed to prevent explosions in acetylene cylinders by acting as a pressure relief mechanism. When the temperature within the cylinder increases excessively, the safety fuse plug melts and allows gas to escape, which prevents the cylinder from reaching a dangerous pressure level. This is crucial in preventing explosions, as acetylene is highly flammable and sensitive to heat.

The technology behind fuse plugs is aimed at providing a fail-safe response to overheating or over-pressurization scenarios. By allowing for a controlled release of gas, these plugs help mitigate the risks associated with acetylene storage and usage.

While safety valves and protective covers serve essential functions in terms of safety and protection, their roles are different. Safety valves can release pressure but do not specifically address the risk of temperature-induced explosions the way fuse plugs do. Protective covers are used to safeguard the cylinders from physical damage rather than actively preventing explosions. Pressure gauges, on the other hand, are used to monitor the internal pressure, but they do not function as protective devices against explosion scenarios. Thus, safety fuse plugs are the components that play a direct and critical role in preventing explosions within acetylene cylinders.
