Safety Precautions
General Safety Considerations
The DirectFlo has been designed to be safe to operate when used properly. Any
device that is pressurized and requires electrical power, however, requires that
certain safety precautions be observed to avoid potentially hazardous situations.
The primary safety-related issues involved in the use of the DirectFlo are listed
below and addressed in detail on the following pages.
1.
Working with a device that is pressurized.
2.
Working with an electrical device.
3.
Working with a device that uses abrasive powders that could be
potentially dangerous if inhaled or ingested in large quantities or
put in constant contact with the skin.
4.
General issues involved in operating machinery.
Working with a Device that is Pressurized
The DirectFlo uses pressurized air to perform its basic function. While Comco's
blasting machines incorporate relief valves and check valves to minimize the risk
of an accident related to air pressure, Comco also recommends the following:
√
The air supply system should have a shutoff valve located
upstream of the blasting machine so that the supply pressure can
be turned off independently of the blaster.
√
Pressure relief valves should be incorporated into the supply
system to minimize the risk from system over pressure.
√
Anyone who will use the DF1400 should be trained in its basic
operation.
√
The DirectFlo should always be turned OFF and vented prior to
performing any maintenance.
√
When replacing parts during maintenance, use only Comco parts
and verify that all installations are correct before using the
DirectFlo.
Improper set-up or use of the DirectFlo DF1400 may result in a condition that could be
hazardous. All fittings and covers must be properly installed and tightened in order to
minimize any hazard.
