Fusible plugs in acetylene cylinders are located:

Overheating acetylene cylinders can cause dangerous decomposition, so a safety feature called a fusible plug is used to vent gas and relieve pressure before an explosion can occur. These plugs melt at a relatively low temperature to open a path for gas to escape. In acetylene cylinders, there are fusible plugs on both ends—top and bottom—so heat from any direction can trigger venting. A plug at only one end wouldn’t protect if heat or flame affected the opposite end, and a plug in the middle wouldn’t provide the proper vent path.
