Permit-Required
Conned Spaces
A conned space has limited openings for
entry or exit, is large enough for entering and
working, and is not designed for continuous
worker occupancy. Conned spaces include
underground reservoirs, ground storage tanks,
elevated tanks, silos, manholes, and pipelines.
Conned Space Tips
• Do not enter permit-required conned spaces
without being trained and without having a
permit to enter.
• Review, understand and follow employer’s
procedures before entering permit-required
conned spaces and know how and when
to exit.
• Before entry, identify any physical hazards.
• Before and during entry, test and monitor for
oxygen content, ammability, toxicity or
explosive hazards as necessary.
• Use fall protection, rescue, air monitoring,
ventilation, lighting and communication
equipment according to entry procedures.
• Maintain contact at all times with a trained
attendant either visually, via phone, or by
two-way radio. This monitoring system
enables the attendant and entry supervisor
to order you to evacuate and to alert
appropriately trained rescue personnel to
rescue entrants when needed.
Refer to 29 CFR 1910.146 for complete
regulations set by OSHA. Refer to your state's
regulations if your state established and operates
their own safety and health programs approved
by OSHA.
Protect Yourself
It is important that you comply with all relative
OSHA and local regulations while installing
and performing any maintenance to the mixer
circulation equipment.
Key OSHA Compliance Standards that must
be followed (and not limited to) are:
• 1910.146 Permit-required conned spaces
• 1910.147 Lockout/Tagout
• 1926.500 Fall Protection
Fall Protection Tips
• Identify all potential tripping and fall hazards
before work starts.
• Look for fall hazards such as unprotected
oor openings/edges, shafts, open hatches,
stairwells, and roof openings/edges.
• Inspect fall protection and rescue equipment
for defects before use.
• Select, wear, and use fall protection and
rescue equipment appropriate for the task.
• Secure and stabilize all ladders before
climbing.
• Never stand on the top rung/step of a ladder.
• Use handrails when you go up or down stairs.
• Practice good housekeeping. Keep cords,
welding leads and air hoses out of walkways
or adjacent work areas.
Refer to 29 CFR 1926.500 for complete
regulations set by OSHA. Refer to your state's
regulations if your state established and operates
their own safety and health programs approved by
OSHA.
Lockout Tagout
When the On/Off switch is in the "ON" position,
the mixer may start up at any time if not already
operating. The mixer's On/Off switch can be
locked out by placing a pad lock thru the door latch
of the controller after the switch has been turned
to the "OFF" position. The On/Off switch is to be
used as the emergency stop.

The AP mixer is designed for the harshest conditions. For proper operation, place AP mixer air
source away from trace gases and high humidity to ensure long life of mixer. If there is not a
clean location, place air source outside of harmful environment.

UNIT CLEANING
The AP Unit is designed to provide continuous
operation with little to no maintenance.
However, in some locations signicant debris
within the pond may eventually get caught on
the unit either restricting the ow pattern at
the manifold or through the intake housing.
Debris may get caught in the air manifold,
either being too large to pass through or
resistant to sliding up the manifold housing.
Often debris will eventually work it's way loose
and pass through the unit or may be pulled
through as other debris passing through the
unit will pull or slide snagged debris through.
If signicant debris is causing the unit to clog,
occasional maintenance and cleaning may be
required.
If required, debris should be carefully
removed from the manifold and be wiped
clean from any scum buildup on the outside
of the pipes that may contribute to preventing
debris from passing through the unit.
Figure 1: Debris Passing Through AP Unit.
WINTER CONDITION RECOMMENDATIONS
In freezing conditions, the AP mixer causes thin ice above and around the unit. If the unit is in a
position that personnel could be walking on ice above the unit, the unit should be shut off, or removed
to protect personnel from thin ice hazards.
