Fabricating processes shutdown

Most waterside problems develop insidiously. Over time, scale and other types of deposit are gradually formed on internal heat transfer surfaces, which gradually raises the cost of providing heat energy. Some types of deposition can be very difficult and costly to remove. Corrosion wastes away the fabric of the plant (sometimes very quickly) and may produce an unexpected and untimely boiler plant shutdown, with a consequential loss of space heating, electricity, or process manufacturing capability. Likewise, fouling reduces the size of waterways and increases boiler operational problems. 

As fabrication shops have accomplished effective safety measures to protect the primary operator, safeguarding only the machine or process operator has been extended toward providing hazard protection for nonoperators, maintenance personnel, and others. Particularly effective in reduction of injury to maintenance personnel and die setters has been the lockout-tagout programs established to assure that nonoperators are not injured during machine shutdown and reconfiguration.
