Potential Carcinogen - Use of Refractory Ceramic Fibers in high temperature applications (above 1805 °F) can
result in the formation of Crystalline Silica (cristobalite), a respirable silica dust. Repeated airborne exposure to
crystalline silica dust may result in chronic lung infections, acute respiratory illness, or death. Crystalline silica is
listed as a (potential) occupational carcinogen by the following regulatory organizations:
Research on Cancer (IARC),
and Health Administration (OSHA), and National Institute for Occupational Safety and Health (NIOSH). Failure to
comply with handling instructions in Table 18.1 may result in serious injury or death.
Crystalline Silica - Certain components in the combustion chamber may contain this potential carcinogen. Read
warnings and handling instructions pertaining to Refractory Ceramic Fibers before commencing service work in
the combustion chamber. Take all necessary precautions and use recommended personal protective equipment
as required (see Table 18.1). Installation and service must be performed by a qualified installer, service agency or
the gas supplier who must read and follow the Installation, Operation, and Service Manual before performing any
work on this boiler. Improper installation, adjustment, alteration, service or maintenance can cause property
damage, serious injury (exposure to hazardous materials) or death.

• Avoid contact with the skin and eyes.
• Avoid breathing in the dust in the combustion chamber.
• Avoid transferring the contamination from clothing and items at the job site.
• Wear
long-sleeved shirt and pants, gloves, and safety goggles.
• Wear a respirator with a N95 rated filter efficiency or better.
• When cleaning the combustion chamber with a vacuum cleaner use water to reduce
airborne dust levels.
• Do not dry sweep silica dust. Pre-wet or use a vacuum with a high efficiency HEPA
filter.
• Take all possible steps to provide adequate ventilation in the boiler room.
• Remove all contaminated clothing after use. Store in sealable container until cleaned.
• Wash contaminated
machine after use to avoid contaminating other clothes.
• Wash all exposed body areas gently with soap and water after contact.
• Discard used RCF components by sealing them in an airtight plastic bag. RCF and
crystalline silica are not classified as hazardous wastes in the United States and
Canada.
• If contact with eyes: Flush with water for at least 15 minutes. Seek immediate medical
attention if irritation persists.
• If contact with skin: Wash affected area gently with soap and water. Seek immediate
medical attention if irritation persists.
• If breathing difficulty develops: Leave the area and move to a location with clean
fresh air. Seek immediate medical attention if breathing difficulties persist.
• Ingestion: Do not induce vomiting. Drink plenty of water. Seek immediate medical
