Elements and Performance Criteria

Elements and Performance Criteria 


Performance Criteria 


Prepare for cleaning operations 


Vehicle is positioned under gantry in accordance with workplace procedures


Documentation is obtained from the vehicle driver to determine the product which has been previously carried in the tanker


The vehicle keys are taken from the driver to prevent 'accidental drive off' before the cleaning process is completed


Appropriate cleaning process is selected for type of tanker/load in accordance with workplace procedures


Cleaning materials are prepared in accordance with manufacturers instructions and workplace procedures


The required personal protection and safety equipment is selected and used in accordance with regulatory requirements and workplace procedures


Steam clean a tanker 


The vehicle is earthed to prevent sparks and explosions


Valves are opened to allow draining of the wash materials and hoses attached in accordance with manufacturers instructions and workplace procedures


All access points, including vents and washing points, are opened and heat-sensitive auto fill probes removed in accordance with workplace procedures


Where the tank has held oil/diesel, a wash consisting of detergent wash and hot water rinse is carried out followed by the application of steam


Where the tank has only held petrol, a steam clean only is carried out in accordance with workplace procedures


After the wash, the unit is left to drain until liquid ceases to drain from the outlet valves and steam stops leaving the vents on the top of the tank


All vents and valves are closed and the auto fill probes reconnected


Plastic seals are placed on valves to signify the completed cleaning of the tanker where required in accordance with workplace procedures


Clean a tanker using water and detergent 


High pressure water and detergent is used to clean around the top of the tanker vents and hatches to remove dirt and they are rinsed clean with water


Valves on the outlet manifold are opened and connected with flexible pipes to the waste storage facility or recycling tanks for the tank cleaner


All hatches are opened and spray balls are placed into the tanks after checking visually for the condition of the tank. Where solid materials are present these are washed out with high pressure water prior to starting the cleaning cycle


Tank is rinsed then washed with tank wash until waste is clear and then it is recycled into a holding tank for reuse leaving the tankers tank to drain


Water in the holding tank is topped up and ph tested and solution is replaced if necessary in accordance with workplace procedures


Tank is rinsed with water in short bursts until the liquid leaving the tank is clear


Top of tank is hosed off again with water, and spray balls are removed


The tank is visually checked, through the hatches with the aid of a torch, for cleanliness


If cleanliness standards have not been achieved, the tanker is rewashed or re-rinsed as required. Hatches are closed


At the conclusion of cleaning operations drainage hoses are removed, manifold checked for cleanliness, and drainage valves closed and sealed to indicate completed process in accordance with workplace procedures


Complete cleaning operations 


Due care is taken to ensure that the disposal of used cleaning materials is in accordance with environmental protection regulations and workplace procedures


Wash water is suitably treated using available water cleaning and separation processes before draining into the sewerage system


Cleaning equipment is cleaned, dried, checked and stored in accordance with workplace procedures


Documentation on the cleaning operations is completed in accordance with workplace procedures and is returned to the driver along with the keys to the vehicle
