ContainmentFormaldehyde Generator/Neutralizer For Biological Decontainmination
General Operating Protocol - All Models
The space to be decontaminated is measured and the volume calculated in cubic feet. The space is then sealed. The relative humidity inside the space is measured or sensed, depending upon the model. The CERTEK Generator/Neutralizer generator is then connected to the space with the appropriately sized connections. The humidifier, formaldehyde, and neutralizer canisters are then loaded with the proper amount of material as calculated using the formulas in the operating manual or the amount determined by other evaluations. The generators are then programmed with the operating sequence choices as determined by the operator and then started by pushing the "Start" button. The space is then conditioned to the proper relative humidity. After this is accomplished, the generator starts formaldehyde insertion. The amount of air required to insert the formaldehyde/neutralizer is circulated through the generator when the insert sequences are active. After the formaldehyde insertion cycle, the generator holds for a preselected contact time (infinitely selectable). After the contact time, the generator automatically begins the neutralizer insert cycle, inserting the neutralizing gas into the space. At the conclusion of this cycle, a preset one hour neutralizer contact cycle begins. When this is complete, the space may be reopened. The product of the reaction between the formaldehyde and the neutralizer is a white powder, which has a slight “fishy” odor. For safety, the space should be ventilated and air samples taken prior to occupancy. Built-in safety features in all of the CERTEK generators permit completely automatic operation without the necessity of a technician’s constant attention.
