10 Boiler Cleaning (continued)
Important Product Safety Information:
WARNING
Some boiler components contain refractory ceramic fibers (RCF). RCF has
been classified as a possible human carcinogen. When exposed to
temperatures above 1805°F, such as during direct flame contact, RCF
changes 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 FIBER PARTICULATES AND DUST
Precautionary Measures:
Do not remove or replace RCF parts or attempt any service or repair work involving RCF
without wearing the following protective gear:
1. A National Institute for Occupational Safety and Health (NIOSH) approved air-purifying
respirator equipped with 100-series particulate filter, as a minimum
2. Long sleeved, loose fitting clothing
3. Gloves
4. Eye Protection
Dampen RCF to be removed with light water spray to prevent fibers from becoming
airborne.
Take steps to assure adequate ventilation.
Wash all exposed body areas gently with soap and water after contact.
Wash work clothes separately from other laundry and rinse washing machine after use to
avoid contaminating other clothes.
Discard used RCF components by sealing in an airtight plastic bag. RCF and crystalline silica
are not classified as hazardous wastes in the United States and Canada.
First Aid Procedures:
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
attention.
