Leaks in a chemical process industries (CPI) facility can run the gamut from creating a costly waste to prefacing a catastrophic failure.. They can be an annoyance, by creating pools of liquid on concrete that can become a possible slipping hazard and housekeeping problem, or a leak that can emit toxic vapors, causing various degrees of harm to personnel. In some cases a leak may be a simple housekeeping...
