Important Product Safety Information:
Refractory Ceramic Fiber Product
WARNING
Some boiler components use materials that contain refractory ceramic fibers (RCF). RCF has
been classified as a possible human carcinogen. When exposed to elevated temperatures, RCF
may change into crystalline silica, a known carcinogen. When disturbed as a result of servicing
or repair, these substances become airborne and, if inhaled, may be hazardous to your health.
Avoid breathing RCF particulates and dust.
Precautionary Measures
:
•
Do not handle RCF parts or attempt any service or repair work involving RCF without wearing the following
protective gear:
1. A properly fitting National Institute for Occupational Safety and Health (NIOSH)-certified air-
purifying respirator with a filter efficiency of at least 95%. Respirator should also include a full
facepiece when handling used RCF. Other types of respirators may be required depending on site
conditions. Current NIOSH recommendations may be found on the NIOSH website
http://www.cdc.gov/niosh/homepage.html
. NIOSH-approved manufacturers, respirators and
associated user instructions are listed on the NIOSH website.
2. Long sleeved, loose fitting clothing that is sufficiently tight around potential entry points for RCF
dust.
3. Gloves.
4. Eye protection, such as goggles, safety glasses with side shields, or full facepiece.
•
Take steps to assure adequate ventilation.
•
Handle RCF carefully to minimize airborne dust. Use hand tools whenever possible.
•
Dampen used RCF with light water spray prior to removal to prevent airborne dust.
•
Do not use compressed air or dry sweeping for clean-up. Frequently clean work area with a vacuum or by
wet sweeping to minimize debris accumulation.
•
Vacuum work clothes before leaving work area. Wash work clothes separately from other laundry and
rinse washing 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 in an airtight plastic bag or container. Refer to local, regional,
state or provincial regulations to identify applicable disposal requirements.
First Aid Procedures
:
•
Eye contact: Flush with water for at least 15 minutes.
Do not rub eyes
. Seek immediate medical attention
if irritation persists.
•
Skin contact: Wash affected area gently with soap and water. Do not rub or scratch affected skin. Seek
immediate medical attention if irritation persists.
•
Nose and throat contact: If these become irritated, leave the area and move to a location with clean fresh
air. Drink water and blow nose. Seek immediate medical attention if symptoms persist.
