WARNING
Fiberglass Wool!
Exposure to glass wool fibers without all necessary
PPE equipment could result in cancer, respiratory,
skin or eye irritation, which could result in death or
serious injury. Disturbing the insulation in this
product during installation, maintenance or repair will
expose you to airborne particles of glass wool fibers
and ceramic fibers known to the state of California to
cause cancer through inhalation.
You MUST wear all necessary Personal Protective
Equipment (PPE) including gloves, eye protection, a
NIOSH approved dust/mist respirator, long sleeves
and pants when working with products containing
fiberglass wool.
Precautionary Measures:
•
Avoid breathing fiberglass dust.
•
Use a NIOSH approved dust/mist respirator.
•
Avoid contact with the skin or eyes. Wear long-
sleeved, loose-fitting clothing, gloves, and eye
protection.
•
Wash clothes separately from other clothing;
rinse washer thoroughly.
•
Operations such as sawing, blowing, tear-out,
and spraying may generate fiber concentrations
requiring additional respiratory protection. Use
the appropriate NIOSH approved respirator.
First Aid Measures:
•
Eye Contact - Flush eyes with water to remove
dust. If symptoms persist, seek medical
attention.
•
Skin Contact - Wash affected areas gently with
soap and warm water after handling.
