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.
