• Point all hoses away from personnel and equipment when connecting or disconnecting.
• Always ensure that the fluid discharge hose is connected before the air hose to prevent
accidental discharge.
The AutoPump System minimizes the potential for accidents with the following safeguards:
Fire and Explosion Protection
Almost all of QED underground fluid extraction systems are pneumatic. This offers many
inherent fire and explosion protection features:
• Compressed air lines eliminates electrical wiring in hazardous areas.
• Aluminum or fiberglass enclosures prevent sparking.
• Standard systems use brass fittings to eliminate sparking hazard.
Personal Protection
On-site, service and maintenance personnel can safely use QED equipment. Safety-in-use is
the primary design feature in all systems. Following are some samples:
• All standard high pressure air hoses have automatic shut off quick-connects on the supply
side which prevents injury due to hose whip or air blown particles. Tubing does not usually
have quick-connect fittings, but is pushed over barbs or pushed into compression fittings.
• Metal regulators and filter bowls are rated for an inlet pressure of 200 psi. The metal air
filter bowl is made of zinc, providing greater pressure and chemical resistance than plastic
bowls and it is less prone to damage if dropped.
Spill Protection
On-site spills cannot always be prevented. QED equipment is designed to take into
consideration such unpredictable occurrences that may happen despite strict adherence to
standardized safety practices.
• The standard air and fluid hoses are rated at over 800 psi burst pressure to prevent
accidental hose breakage.
• Down well quick-connects have locking features to prevent accidental disconnections.
