Many process tanks are cleaned manually. For manual cleaning, workers will need to go into the confined space of the tanks, which is never without risk.
Still today, manual cleaning leads to incidents and accidents, sometimes with dramatic outcome.
Avoid entering confined spaces
With Cleaning-In-Place, you do not require to open the equipment or enter the tank. The spray balls or spray jets take care of the internal cleaning of the tanks. Workers do not need to enter the tank, and do not risk to get into contact with the detergents or experience lack of oxygen.
If you need to enter the tank for whatever reason, be informed, prepared and stay safe.
