Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the required performance needed to demonstrate achievement of the element. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria



Prepare for cleaning operations 

1.1 Vehicle is positioned under gantry in accordance with workplace procedures

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

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

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

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

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

Steam clean a tanker 

2.1 The vehicle is earthed to prevent sparks and explosions

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

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

2.4 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

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

2.6 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

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

2.8 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 

3.1 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

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

3.3 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

3.4 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

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

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

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

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

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

3.10 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 

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

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

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

4.4 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
