Effective monitoring means are the gas detector sensors. Rooms with ozonation plants shall equipped with ventilation at floor level actuated automatically by the gas detectors. Ventilation shall guarantee at least three complete changes of air per hour. The bidder has to confirm and fulfill ozonisation capacities and operation of the system as adequate the following as per the guidelines of Environment problems such as supply failure, interruption in supply of ozone gas etc. Unit’s start-ups and shut downs- planned / forced. Quick stabilization of the system after any interruption. Dozing points to be selected in such a way that Ozonation is ensured for complete system. It should ensured that no ozone-depleted pockets are left out the system. The health and safety aspects are required to be elaborated so that proper precautions can be taken during operation and maintenance. Operations: On the basis of manufacturers operation & maintenance manual the supplier shall provide instruction for the operation of the ozonating plant make them accessible to all personnel who work at near the plant. Such instruction shall include the following indication: • Instruction on the operation of the parts of the plant • Starting and shut down sequence • Action in the event of the faults • Preventive measures to avoid untoward situation. Safety Signs: Safety signs marked shall be in accordance with the safety concerns at the working place. The technology design & details as per provided and approved by technology provider.
