COMPRESSEDAIR 1. Avoid contact with skin, clothing, and eyes.
Compressedair or gases should never be used to
cleanclothing orthe body.Compressedaircanpierce
the"skin and cause severeand very painful injury.
Neveruseyour handto checkair, gas,or liquid flow
rates.Do not engagein "horseplay" with air, gas,or
liquid hoses. Observeall applicableregulations as
relatedto compressedgases.
SODIUMFILLEDVALVES
When handling sodium filled valves always wear
approvedsafetygoggles,a hat or cap,longsleeves,
and gloves. If refacing of sodium filled valves is
required, do not exert undue force at the grinding
wheel asthis couldcrackthe hollow valvestemand
allow the sodium to escape.
Donot handlebrokensodiumfilled valveswith bare
hands.Sodiumor sodium residuecan causesevere
burns. Sodium burns are of the same nature as
causticburns.Washburnswith largevolumesofcold
water, then neutralize with vinegar. The affected
parts should then be treated as a burn and medical
attention sought.

INTOXICANTSAND NARCOTICS
Workers under the influence of intoxicants and/or
narcotics are unsafe workers and are a hazardto
themselvesand other employees.
SAFETYPRACTICESFORHANDLINGACIDS.
Throughout this manual, acid cleaning procedures
are recommendedfor certain castings or piecesof
equipment.
I
WARNING'
Always add the acid to the water - never add water
to acid when mixing solution.
2. Descaling operations should be performed
away from all fire, sparks or other ignition
sources.
3. Keepacids off of concrete floors, as it attacks
lime in the concrete. If solution does get on
concretesurfaces,applyan alkaline solutionto
neutralize.
4. 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
aluminum, zinc,cadmium,tin, sulfides,arsenic
and cyanides,poisonousand explosivegases
may be generated. When descaling is being
done in closed equipment. install proper
ventilation to carry the gasesaway. When an
open tank or crock is used, gases should be
diluted by adequate air flow above the open
tank.
5. Always fill closedvesselsfrom bottom up.
6. Be sure that there are no leaks in the vessel
being descaledwhich will permit solution to
leak into opposite side of equipment. Good
practice is to fill the opposite side of the
equipmentbeingdescaledwith water toa level
higher than the acid solution.
7. Use an acid-proof pump, or an inexpensive,
expendableone.
8. When mixing with water, pour acid into the
water, do not pour water in concentratedacid.
9. Do not agitate acid solutions with air.
10. Applications of acid should be followed by
thorough rinsing, then neutralizing with an
alkalinesolutionto removeall acidicresidue,to
preventfurther action.
11. Store acid solutions in either an acid-proof
wooden or synthetic rubber lined steel
container should be used.
12. Checksteel equipmentto be treated with acid
solution for copperor brassfittings or fusible
metal plugs. If possible, dissimilar metals
shouldberemovedpriortodescalingto prevent
electrolytic action which might interfere with
the inhibiting actionofacidsolution.Donotuse
acid to descale equipment constructed of
aluminum.
