Abstract
The drum cap venting device generally includes a venting cap assembly. The venting cap assembly can include a venting cap and a venting key. The venting cap generally includes a main body portion, a valve portion and a ring portion. The venting key generally includes a key body portion and a venting tube. The venting key is rotatably engageable with the valve portion of the venting cap such that rotation of the key provides a passageway of continuous fluid communication from the drum, through conduits in the venting cap, and out the venting tube of the venting key. As a result, any release or evacuation of pressurized gasses from the drum is directed away from the user to a safe area or device.
