SAFETY DECALS
SAFETY DECALS ARE PROVIDED WITH YOUR HEIL DRY BULK MATERIALS TRANSPORT . PLEASE CAREFULLY READ THE MESSAGES CONTAINED WITHIN THE DECALS AND BE ALERT TO THE POSSIBLILITY
OF PERSONAL INJURY OR DEATH.

WARNING
Do not exceed working pressure. If pressure rises
above limits, shut down immediately and investigate.
WARNING
NEVER open manhole unless
tank is completely depressurized. Even a slight amount of residual pressure will cause manhole to fly open when unlatched.

WARNING
The Relief Valve must be operational
to maintain system pressure within
safe limits. Failure to properly maintain the relief valve may cause property damage, potential injuries and
death.
WARNING
When unloading, the discharge
hose must be secured at both
ends prior to pressurizing unit.
Always relieve pressure in discharge hose before disconnecting it.
16

NOTICE
Blowdown valve should be OPEN at all
times except when unloading. This
will help relieve pressure buildup due
to changes in ambient temperature,
friction, product expansion, etc.
WARNING
To avoid suffocation, never enter a tank containing pulverants,
liquids, flammable or caustic
materials. Always follow all confined space entry procedures.
CAUTION
To avoid product contamination or mixing of incompatible materials, clean tank thoroughly before switching payloads.
CAUTION
To prevent a vacuum from developing when unloading without
pressure, open manhole before opening discharge valve.
WARNING
Never operate this
bulk transport unless you are fully
aware of the location of all the control valves and shut
down procedure.

17

CAUTION
Vehicle safety checks should be performed daily prior to
operation.

CAUTION

CAUTION

If a leak is discovered during
operation, shut down immediately and repair the leak.

To avoid spillage, product discharge valves must be closed
prior to loading and while in
transit.

Notice
All check valves must be operational to prevent product
back-up into the supply
lines.
WARNING
Maintain non-skid surface at top of tank
free of ice, snow, sleet, rain, oil, grease,
etc. prior to climbing on top.

WARNING
Decals are posted on the tank to alert the operator of potential
dangers. Replace decals when illegible.
