TriangleTube Prestige Excellence Part 1 - Manual (Page 68)

The combustion chamber insulation
contains ceramic fibers, which are clas-
sified as a possible human carcinogen.
When exposed to extremely high tem-
peratures, the ceramic fibers, which
contain crystalline silica, can be con-
verted into cristobalite.
Avoid Breathing and Contact with Skin
and Eyes
When removing or repairing the combustion
chamber insulation follow these precaution
measures:
1. Use a NIOSH approved respirator which
meets OSHA requirements for cristobalite
dust, similar to N95. Contact NIOSH at
1-800-356-4676 or on the web at
www.cdc.gov/niosh for latest recommen-
dations.
2. Wear long sleeved, loose fitting clothing,
gloves and eyes protection.
3. Assure adequate ventilation.
4. Wash with soap and water after contact.
5. Wash potentially contaminated clothes
separately from other laundry and rinse
washing machine thoroughly.
6. Discard used insulation in an air tight
plastic bag.
NIOSH Stated First Aid:
Eye/Skin: Immediately irrigate
Breathing: Clean fresh air
