26. SAFETY PRACTICES FOR HANDLING ACIDS
Cleaning with acid for certain castings and pieces of equipment is frequent. In handling them, follow these
recommendations:
-
Avoid contact with skin, clothing and eyes.
-
Descaling operations should be performed away from all fire, spark or other ignition sources.
-
Keep acid off of concrete floors because it attacks the lime in the concrete. If solution does get on concrete
surfaces, apply an alkaline solution to neutralise.
-
Acids can react with metals to form various gases. Generally, acid solutions on lime scale and rust result in
the formation of harmless carbon dioxide. However, when acids contact aluminium, zinc, cadmium, tin,
sulphur, arsenic or cyanide, poisonous and explosive gases may be generated. When descaling is done in
closed equipment, install proper ventilation to carry the gases away.
-
Always store containers closed, placing these in their normal position.
-
Be sure that there are no leaks in the vessel being descaled, which will permit solution to leak into opposite
side of equipment. Good practice is to fill the opposite side of the equipment being descaled with water to
level higher than the acid solution.
-
Use an acid-proof pump, or an inexpensive, throw-away pump.
-
Do not agitate acid solutions with compressed air.
-
Applications of acid should be followed by thorough rising, then neutralising with an alkaline solution to
remove all acidic residue, to prevent further action.
-
Store acid solutions in either an acid-proof wooden or synthetic rubber lined steel container.
-
Check steel equipment to be treated with acid solution for copper or brass fittings or fusible metal plugs. If
possible, dissimilar metals should be removed prior to descaling to prevent electrolytic action which might
interfere with the inhibiting action of acid solution. Do not use acid to descale equipment constructed of
aluminium.
27. ENGINE LIFTING AND HANDLING
-
The use of cloth slings is recommended to avoid damaging the equipment with rough movements.
-
Assure that the slings do not come into contact with sensitive parts of the equipment.
-
Correctly inspect all anchor points so that there is no defective welding, loose screws, etc. that might
jeopardize the lifting of the equipment.
-
Verify that all pertinent structures have been inspected, are in good condition, and can support at least the
weight of the equipment plus 10%. If you are not sure, weigh the equipment prior to lifting it.
-
Prior to lifting it, be sure to balance the equipment to the maximum, using slings of different lengths if
necessary.
-
Keep all personnel away when the unit is in the air.
-
Do not lift the equipment further than necessary.
