Refractory Ceramic Fibers (RFC)
Personal Protective Equipment Recommended - Read the following warnings and
handling instructions carefully before commencing any service work in the combustion
chamber. The insulating material on the inside of the burner plate contains Refractory Ceramic Fibers and
should not be handled without personal protective equipment.
Potential Carcinogen - Use of Refractory Ceramic Fibers in high temperature
applications (above 1000
o
C/1800ºF) 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:
International Agency for Research on Cancer (IARC),
Canadian Centre for Occupational Health and Safety (CCOHS), Occupational Safety and Health Administration
(OSHA), and National Institute for Occupational Safety and Health (NIOSH). Failure to comply with handling
instructions in Table 14-1 may result in serious injury or death.
Crystalline Silica - Certain components confined in the combustion chamber may
contain this potential carcinogen. Improper installation, adjustment, alteration, service or
maintenance can cause property damage, serious injury (exposure to hazardous materials) or death. Refer to
Table 14-1 for handling instruction and recommended personal protective equipment. Installation and service
must be performed by a qualified installer, service agency or the gas supplier (who must read and follow the
supplied instructions before installing, servicing, or removing this boiler. This boiler contains materials that have
been identified as carcinogenic, or possibly carcinogenic, to humans).
Table 14-1 Handling Instructions for Refractory Ceramic Fibers (RCF)
Reduce the Risk of Exposure Precautions and Recommended Personal Protective Equipment
Avoid contact with skin and eyes

Wear long-sleeved clothing, gloves, and safety goggles or glasses .
Avoid breathing in silica dust

Wear a respirator with an N95-rated filter efficiency or better. 1

Use water to reduce airborne dust levels when cleaning the combustion chamber.

Do not dry sweep silica dust. Pre-wet or use a vacuum with a high efficiency filter.
Avoid transferring contamination

When installing or removing RFCs, place the material in a sealable plastic bag.

Remove contaminated clothing after use. Store in sealable container until cleaned.

Wash contaminated clothing separately from other laundry.
First Aid Measures
If irritation persists after implementing first aid measures consult a physician.

Skin - Wash with soap and water.

Eyes - Do not rub eyes; flush with water immediately.

Inhalation – Breathe in fresh air; drink water, sneeze or cough to clear irritated
passage ways.
