Steam Whistle

The Steam Whistle is a block from Flaxbeard's Steam Power. It is used as protection against machine-based explosions. It must be placed directly on the machine to work. It will create a loud sound to alert the player when the machine it is placed on is reaching dangerous pressure levels. It will sound before a Rupture Disc will pop, allowing for the player to solve the situation before losing steam.
