Handling ceramic fiber materials
REMOVAL OF COMBUSTION CHAMBER LINING
The combustion chamber insulation in this appliance
contains ceramic fiber material. Ceramic fibers can
be converted to cristobalite in very high temperature
applications. The International Agency for Research
on Cancer (IARC) has concluded, “Crystalline silica
in the form of quartz or cristobalite from occupational
sources is carcinogenic to humans (Group 1)”. Normal
operating temperatures in this appliance are below the
level to convert ceramic fibers to cristobalite. Abnormal
operating conditions would have to be created to convert
the ceramic fibers in this appliance to cristobalite.
The ceramic fiber material used in this appliance is
an irritant; when handling or replacing the ceramic
materials it is advisable that the installer follow these
safety guidelines.
Avoid breathing dust and contact with skin and eyes.
• Use NIOSH certified dust respirator (N95).
This type of respirator is based on the OSHA
requirements for cristobalite at the time this
document was written. Other types of
respirators may be needed depending on the job
site conditions. Current NIOSH recommendations
can be found on the NIOSH website at
http://www.cdc.gov/niosh/homepage.html.
NIOSH approved respirators, manufacturers, and
phone numbers are also listed on this website.
• Wear long-sleeved, loose fitting clothing, gloves,
and eye protection.
Apply enough water to the combustion chamber
lining to prevent airborne dust.
Remove the combustion chamber lining from the
water heater and place it in a plastic bag for disposal.
Wash potentially contaminated clothes separately
from other clothing. Rinse clothes washer thoroughly.
NIOSH stated First Aid.
Eye: Irrigate immediately.
