17.22 Handling Previously Fired Combustion Chamber Insulation
WARNING!
The combustion chamber insulation contains ceramic fibers, which
are classified as a possible human carcinogen. When exposed to
extremely high temperatures, the ceramic fibers, which contain
crystalline silica, can be converted into cristobalite.
Avoid Breathing and Contact with Skin and Eyes.
When removing or repairing the combustion chamber insulation follow these
precaution measures:
• Use a NIOSH approved respirator which meets OSHA requirements for cristobalite dust,
similar to N95. Contact NIOSH at1-800-356-4676 or on the web atwww.cdc.gov/niosh for
latest recommendations.
• Wear long sleeved, loose fitting clothing, gloves and eyes protection.
• Assure adequate ventilation.
• Wash with soap and water after contact.
• Wash potentially contaminated clothe separately from other laundry and rinse washing
machine thoroughly.
• Discard used insulation in an air tight plastic bag.
NIOSH Stated First Aid:
• Eye/Skin: Immediately irrigate
• Breathing: Clean fresh air
