Steam Method of Cleaning
WARNING
Compressed air can move particles so that they
cause injury to the user or to other personnel.
Make sure that the path of the compressed air is
away from all personnel. Wear protective goggles
or a face shield to prevent injury to the eyes.
WARNING
Be careful when cleaning with steam. Steam can
cause serious burns. Wear protective clothing,
gloves, and eye protection. Never expose your
skin to steam.
Use the following procedure to clean the tank with
steam:
1. Remove all the parts from the tank. Install the
drain plug.
2. Fill the tank 1/4 full with a solution of water and
sodium bicarbonate or sodium carbonate. Mix
0.5 kg (1 lb) per 4 liter (1 gal) of water.
3. Mix the solution in the tank using air pressure.
Make sure all the surfaces on the inside of the
tank are flushed with the solution. Drain the tank.
4. Put steam into the tank until the tank does not
have odors and the metal is hot. Steam vapors
must come from all the openings.
5. Flush the inside of the tank with boiling water.
Make sure all the loose material is removed from
the inside of the tank.
6. Make an inspection of the inside of the tank. If it is
not clean, repeat Step 4 and Step 5 and make an-
other inspection. When making inspections, use a
light that is approved for locations with flammable
vapors.
7. Put plugs in all the openings in the tank. Wait
15 minutes, then remove the inlet and outlet
plugs. Test a sample of the vapor with a special
indicator for gas vapors. If the amount of flamma-
ble vapors is above the lower flammable limit, re-
peat the cleaning procedures.
