3. Observe Codes of Practice in relevant country When fitting the leak detection fluid header tank in the Ex area the access shaft or in the open ensure that neither surface or precipitation water nor dirt or drifting sand can penetrate the header tank or the cable junction box The leak detection fluid header tank must be mounted high enough above the interstitial space for the static pressure of the leak detection fluid on all parts of the interstitial space to be sufficient to cause the leak detection fluid to escape in a leak situation and the fluid level in the leak detection fluid header tank to fall until the alarm is triggered The minimum distance between the crown of the tank and the lower edge of the leak detection fluid header tank generally depends on the specific gravity of the stored material and in the case of underground tanks on possible groundwater or water levels above the crown of the tank For storage containers below ground the leak detection fluid header tank must be mounted at least 30 cm above the crown of the storage container Where the tested system over pressure of the interstitial space of the tank is 0 6 bar the leak detection fluid header tanks may not be set higher than 5 5m above the base of the tank in relation to the filling level screw The minimum distance between the tank crown and the leak detection fluid header tank in relation to the specific gravity of the stored material can be ascertained from the
