Decontamination procedures for chemical process equipment.
NIOSH 1981 Mar; :159-179
The basic elements of chemical process equipment decontamination procedures were described. The decontamination procedure was said to begin with the identification of equipment and the contaminant. It was recommended that the facility and process equipment be designed with consideration for decontamination, with all wood and concrete surfaces painted. Physical and chemical cleaning techniques were described, and high pressure water or solvent flushing were cited as the most common methods. The verification of decontamination was discussed and several wipe tests were described. The disposal of contaminated waste was addressed, and recycling of flush solvents, incineration, landfilling, and treatment were described as useful techniques. Personal protective equipment and hygiene were found to be important during the decontamination process, as equipment integrity and local exhaust ventilation may be overridden as part of the decontamination process. The importance of procedural controls in the decontamination process was stressed.
