SCANNER SAFETY AND LOCAL CONTROLS
Table. 2. Compressed Air and Coolant Precautions
Red hoses, compressed air (See
Fig 12)
Energized air lines can cause
projectile motion and hose-whip that
is dangerous to body and eyes.
Ensure that compressed air to the scanner
is isolated and de-energized; wear eye
protection.
Green hoses, pressurized water
/ glycol coolant mixture
(See Fig 12)
Pressurized or full coolant lines can
lead to contact with skin or eyes, as
well as spill potential
Ensure that coolant lines are blocked off or
drained, and chiller pump is disabled. Wear
eye protection. Review mill procedures for
handling fluid spills prior to work.
Accidental removal of black
flow meter knob
(See Fig 12)
Flow meter adjustment knob will pop
off unexpectedly if turned opened too
far; a strong stream of coolant will
shoot toward the upper torso and
face
Use care when turning adjustment dial to
gain more flow. Stop turning knob when it is
seen that the flow stops increasing. About
two extra turns are required to remove knob
from full open state. Keep a firm grip on
knob. Wear eye protection.
TES pressurized water / glycol
coolant hoses, both ends of
beam (See Fig 13)
Working on coolant lines, full or
pressurized, can lead to contact with
skin or eyes, as well as spill potential
Disable TES pump. If required, partially or
fully drain TES below level of work.
