and CO monitor or both. If CO monitor is not used, air MUST
be tested FREQUENTLY to ensure proper air quality.
□
3. Clean, properly maintained NIOSH-APPROVED
SUPPLIED-AIR RESPIRATOR.
ALL components should
ALWAYS be present. NEVER operate without inner lens in
place. Thoroughly inspect ALL components DAILY for
cleanliness and wear. ANY substitution of parts voids NIOSH
approval i.e. cape, lenses, breathing hose, breathing air supply
hose, air control valve, cool air or climate control devices.
□
4. OSHA required BREATHING AIR FILTER
for removal
of moisture and particulate matter from breathing air supply.
THIS DEVICE DOES NOT REMOVE OR DETECT CARBON
MONOXIDE (CO). ALWAYS USE CO MONITOR ALARM.
□
5. ASME CODED BLAST MACHINE
sized to hold 1/2
hour abrasive supply. ALWAYS ground machine to eliminate
static electricity hazard. Examine pop up valve for alignment.
Blast machine MUST be fitted with a screen to keep out foreign
objects and a cover to prevent entry of moisture overnight.
□
6. AIR LINE FILTER
installed AS CLOSE AS POSSIBLE
to machine inlet. Sized to match inlet piping or larger air supply
line. Clean filter DAILY. Drain OFTEN.
□
7. REMOTE CONTROLS
MUST be in PERFECT
operating condition. ONLY use APPROVED spare parts,
including twin- line hose. DAILY: test system operation and
check button bumper and spring action of lever and lever lock.
DO NOT USE WELDING HOSE.
□
8. BLAST HOSE
with ID 3 to 4 times the nozzle orifice.
Lines MUST be run AS STRAIGHT AS POSSIBLE from
machine to work area with NO sharp bends. Check DAILY for
internal wear and external damage.
□
9. HOSE COUPLINGS, NOZZLE HOLDERS
fitted
SNUGLY to hose end and installed using PROPER coupling
screws. Coupling lugs MUST be snapped FIRMLY into locking
position. Gasket MUST form positive seal with safety pins
inserted through pin holes. Check gaskets and replace if ANY
sign of wear, softness or distortion. ALWAYS install safety
cables at every connection to prevent disengagement. Check
nozzle holder for worn threads. NEVER MIX DIFFERENT
BRANDS OF COMPONENTS. Check each of these
components DAILY.
□
10.
Inspect
NOZZLE and GASKET
DAILY for wear.
Replace nozzle when 1/16" larger than original size or if liner
appears cracked. Check nozzle threads for wear.
□
11.
Use abrasive that is properly sized and free of harmful
substances; such as, free silica, cyanide, arsenic or lead.
Check material data sheet for presence of toxic or harmful
substances.
□
12.
Test surface to be blasted for toxic substances. Take
appropriate, and NIOSH required, protective measures for
operator and bystanders which pertain to substances found on
the surface to be blasted.
