Safety Precautions
August 2005
1.1 Cont’d
Before actual shotblasting can begin, the operator should be certain that the 1-9DEZ will
clear all obstructions in the work area. Work areas must be dry and clean (no loose
debris) before cleaning can begin.
WARNING: LOOSE DEBRIS MAY CAUSE A CATASTROPHIC FAILURE OF THE
BLAST WHEEL RESULTING IN SERIOUS INJURY.
WARNING: KEEP ALL GUARDS IN PLACE - THE 1-9DEZ IS EQUIPPED WITH
GUARDS OR COVERS FOR PARTS THAT MAY BE HAZARDOUS. IF ANY
GUARDS ARE REMOVED FOR MAINTENANCE, VERIFY THAT THE GUARDS
HAVE BEEN REPLACED AND ARE FUNCTIONING PRIOR TO USING THE 1-9DEZ.
REFER TO DRAWINGS 650-0011 FOR CORRECT PLACEMENT OF GUARDS,
COVERINGS AND OTHER 1-9DEZ COMPONENT PARTS.
All personnel in the immediate work area must wear safety glasses with side shields
and hearing protection whenever the 1-9DEZ is blasting; protective clothing is also
recommended. Long sleeve shirts and safety shoes should be worn. The abrasive used
in the 1-9DEZ impacts the work surface at high velocity; therefore any leakage during
normal operation may sting personnel in the surrounding area. The blast head must be
sealed to the work surface during operation to prevent abrasive leakage. Loose
clothing, long hair and jewelry should not be worn when operating or maintaining the 1-
9DEZ.
1.2 Safety – Mechanical
