(\u0026lt;= 8%). _______________________________________________________________________________________________________
9. Opening of the angle valve (if present) with elevation of the cup (components on the manhole) for the drainage of oil in the tank to be carried out with spark-proof tools. _______________________________________________________________________________________________________
10. If there is significant product in the tanks and its quantification, measure with metric and auction information table in the presence of the operator, making the monitoring of water with a special paste detector. The transfer of the product will still be reused in adjacent tanks by using the adf pump connected to PVC pipe. _______________________________________________________________________________________________________
11. Manual removal or by wire rope winch with tripod placed on aluminum, spark-proof tools, equipment pdu on the manhole cover and positioning the same on a PVC sheet. _______________________________________________________________________________________________________
12. In order to avoid risks due to obstruction of materials and equipment must be always respected the following criteria:
- the waste must be immediately collected and stored according to the types;
- waste materials should be put aside in order and then removed from the site;
- any equipment no longer used should be placed on the truck;
- any spillage of product should be immediately absorbed and clean;
- access roads should be maintained to the operating sgombere from materials of any nature and kind
_______________________________________________________________________________________________________
13 . Check presence of the link grounding of the tank, ensuring the continuity of the system to the network before performing open manhole. _______________________________________________________________________________________________________
14. Cleaning cover with pdu idrojet and aspiration of liquid by suction pump connected to PVC piping or equipment always manually using PVC, loosening bolts and nuts holding the manhole cover using non-sparking tools, manual removal or by winch with cable rope placed on tripods in aluminum manhole cover using ropes or cords are suitable and spark, luggage cover away from pdu well (not to impede the movements of operators) and on a PVC sheet previously drawn (not to contaminate the soil from pollutants). Home mechanical ventilation of the gas in the tank, using a suction machine and a special pipe explosion (the passage of gas through a suction filter with active carbon acts to reduce the danger of them) during this phase must be used and to use non-sparking equipment. During the 7-8-9-10-11-12-13-14-15 operator used in the cleaning of the well and disassembly of the equipment of the PDU must be assisted and monitored by other operators.
_______________________________________________________________________________________________________
15. Aspiration of the existing sludge in the tank with hand pump adf-specific works in the presence of explosive vapors. _______________________________________________________________________________________________________
16. Continuation of mechanical ventilation by car exhaust gas explosion (the passage of gas through a suction filter with active carbon acts to reduce the danger of them) inside the tank and subsequent ventilation when using the same machine vacuum explosion-proof up to the LEL value of \u0026lt;8%. The operation will be repeated whenever the explosimeters indicate exceeding the safety threshold. The vapors are vacuumed filtered through charcoal filters. Verify that the presence of oxygen is> = 19%. _______________________________________________________________________________________________________
17. Water mist and filming by launching idrojet connected to the in-vehicle inside the tank in order to reduce any residual vapors and aspiration of the resulting operation. _______________________________________________________________________________________________________
18. Placing aluminum ladder in the manhole of the tank. Entry Operator (Equipped with a harness attached by carabiner to the rope winch aluminum supported by aluminum tripod, another operator acting on the winch to power the cable so that the descent of the other operator carried out in safety), appropriately dressed in white overalls cotton or terylene, boots and / or anti-static shoes, gloves and PVC mask equipped with filters or air from a compressor outside, inside the serbatoio.Se necessary you can 'repeat the operation described in paragraph 17. The other two players in the square, dressed in white cotton or terylene overalls, boots and shoes antistatic / PVC gloves, harness and already worn masks or air filters in an easily accessible position, will assist the operator who is inside the tank. The operator inside the tank will be brought out immediately if the oxygen level to \u0026lt;= 18%. If you have any problems inside the tank operator, these must be communicated to employees through the square on the movements of the rope winch (tears) in numbers previously agreed, at the time that the operator is located outside the tank to check the his being sick and perform emergency procedures. During the entire operation to clean the inside of the tank must be always maintained the aspiration / ventilation air through the use of machine / vacuum fan explosion, and the continuous monitoring of the vapors inside the tank by explosimeters provided (the LEL must be \u0026lt;8%).
