2-GALLON ASME TANKS – SAFEGUARDS
HAZARD
CAUSE
SAFEGUARDS
Fire
Solvents and coatings can be highly
flammable or combustible, especially
when sprayed.
1. Adequate exhaust must be provided to keep the air free
of accumulations of flammable vapors.
2. Smoking must never be allowed in the spray area.
3. Fire extinguishing equipment must be present in the
spray area.
Fire – Pressure tank
Vapors from flammable liquids can
catch fire or explode.
Keep tank at least 10 feet away from sources of ignition.
Ignition sources include hot objects, mechanical sparks, and
arcing (non -explosion proof) electrical equipment.
Explosion Hazard –
Pressure Tank –
Static Electricity
Static electricity is created by the
flow of fluid through the pressure
tank and hose. If all parts are not
properly grounded, sparking may
occur. Sparks can ignite vapors from
solvents and the fluid being sprayed.
1. Ground the pressure tank by connecting one end of 12
gauge (minimum) ground wire to the pressure tank and
the other end to a true earth ground. Local codes may
have additional grounding requirements.
2. See illustration on page 6 for grounding and grounding
hardware required.
Explosion Hazard –
Pressure Tank –
Rupture
Making changes to a pressure tank
will weaken it.
1. Never drill into, weld, or modify the tank in any way.
2. Do not adjust, remove, or tamper with the safety valve.
If replacement is necessary, use the same type and rating
of valve.
Explosion Hazard –
Galvanized Tanks –
Material Compatibility
Halogenated hydrocarbon solvents
– for example 1-1-1 Trichloroethane
and methylene chloride – can
chemically react with aluminum
parts and components and cause an
explosion hazard. These solvents
will also corrode the galvanized tank
coating.
1. Read the label or data sheet for the material. Do not
use materials containing these solvents with galvanized
pressure tanks. Stainless steel tank models may be used
with halogenated solvents.
2. Refer to specifications chart to ensure that fluids are
chemically compatible with the tank wetted parts.
Before placing fluids or solvents in tank, always read
accompanying manufacturer’s literature.
General Safety
Improper operation or maintenance
may create a hazard.
Operators should be given adequate training in the safe
use and maintenance of the equipment (in accordance with
the requirements of NFPA-33, Chapter 15 in U.S.) Users
must comply with all local and national codes governing
ventilation, fire precautions, operation, maintenance, and
housekeeping (in the U.S., these are OSHA sections 1910.94
and 1910.107, and NFPA-33.
The following hazards may occur during the normal use of this equipment. Please read the following chart.
WARNING
High pressure can cause
serious injury.
Pressure is maintained in a
pressure tank after the
system has been shut
down.
Always follow this
procedure to relieve
pressure from the tank.
!
1. Turn off the main air supply to the tank.
2. Close the air inlet valve located on the tank air manifold.
3. Bleed off air in the tank by turning the air relief valve (5) thumb screw counterclockwise. Wait until all the
air has escaped through the valve before removing the pressure tank cover or fill port cap.
4. Leave the air relief valve open until you have reinstalled the tank cover or fill port cap.
PRESSURE RELIEF PROCEDURE
To reduce the risk of injury, follow the pressure relief procedure below
• Before checking or servicing any
part of the spray system
• Before attempting removal of fill
port cap or tank cover
• Whenever the tank is left
unattended
