Triangle Engineering of Arkansas JD - Manual (Page 4)

Access doors to a duct system should never be opened
when the fan is running. On the downstream (or pressure)
side of the system, releasing the door with the system
in operation may result in an explosive opening. On the
upstream (or suction) side, the inflow may be sufficient to
suck tools, clothing, etc., and may even cause a man to lose
his balance.
When a fan is being started for the first time, a complete
inspection of the duct work and interior of the fan should be
made (with the power locked off), to make certain there is no
foreign material which can be sucked into or blown through
the duct work.
FAN GUARDS, INLET and OUTLET GUARDS,
DRIVE GUARDS
All fans have moving parts which require guarding in
the same way as other moving machinery. In areas which
are accessible only to experienced personnel, a standard
industrial type guard may be adequate. This type of guard
will prevent the entry of thrown or dropped objects with a
minimum restriction of air flow.
Where the fan is accessible to untrained personnel or
the general public, maximum safety guards should be used,
even at the cost of some loss of performance. Fans located
less than 7’ above the floor require special consideration as
specified in the Occupational Safety and Health Act. Roof
mounted equipment will require guards when access is
possible, for example, by climbing children.
Upblast and hooded fans may be connected directly to
ductwork which will prevent contact with the internal moving
parts, but when the inlet or outlet is exposed, a suitable
guard should be installed. Accordingly, roof openings for
Upblast and Hooded Fans can be easily and neatly fitted
with framed safety guards.
Fans may be driven from the motor shaft or through a belt
drive. In every case where the bearing assembly, rotating
shaft, sheaves or belts are exposed, a suitable guard should
be provided.
