Ensure that the team is protected. Obtain
the necessary safety equipment specified
for confined space exposure to those
materials, paying particular attention
to safety harness/line, and respiratory
support and protection. This may include
contaminant detection equipment and
positive ventilation to refresh air in the
hopper.
At least one attendant must be equipped
with communications capability, to summon
outside aid in the event that the hopper
worker is overcome. Equip the entrant with
a safety harness and safety line.
Review the hazards. Review the
procedures. Understand the use of the
protective equipment. Know the steps
to take in emergencies. Practice them.
Train the observer to summon aid, and
not attempt hopper entry if the entrant is
overcome.
Set brakes or block the drill wheels to
prevent movement.
Disrupt any crusting or bridging that may be
present. From outside the hopper, break up
any hard surfacing on top of the material,
or forming layers within the material. Such
layers are extremely dangerous to stand
on.
5.12 Hydraulic
Maintenance
To function properly, the hydraulic systems
must be free of contaminants, free of air
and fully charged with oil.
Do not loosen (“crack”) fittings
with a circuit engaged. With a
circuit in Neutral or Float, crack
hydraulic lines carefully. There
may still be pressure in lines
even with the circuit in Float or
Neutral. Wear gloves and eye
protection. Crack fittings slowly.
Supply fluid slowly. When circuit
is energized, watch for fluid
emergence at a safe distance.
Escaping fluid under pressure
can penetrate the skin causing
serious
injury. Avoid the
hazard by relieving pressure
before disconnecting hydraulic
lines. Use a piece of paper or
cardboard, NOT BODY PARTS,
to check for suspected leaks.
Wear protective gloves and
safety glasses or goggles when
working with hydraulic systems.
If an accident occurs, seek
immediate medical attention
from a physician familiar with this
type of injury.
Check hydraulic fluid level in tractor
reservoir and fill to proper level. Add fluid
to system as needed.
