SECTION 2 - HAZARDS IDENTIFICATION
Emergency Overview
Gray. Solid ply rolls. Not applicable under normal conditions of use. Generally not required under normal
conditions of use.
Acute Potential Health Effects/ Routes of Entry
Inhalation Not applicable under normal conditions of use.
:
Eyes Not applicable under normal conditions of use.
:
Ingestion Not applicable under normal conditions of use.
:
Skin May cause mild irritation.
:
Aggravated Medical Conditions
Pre-existing eye, skin and respiratory disorders may be aggravated by exposure.
Chronic Health Effects
This product contains granular materials which may cause mechanical skin, eye or respiratory irritation. The
International Agency for Research on Cancer (IARC) has classified ceramic fiber, fibrous glasswool, and
mineral wool (rockwool and slagwool) as possible human carcinogens (Group 2B) based on sufficient evidence
of carcinogenicity in animals but insufficient data in humans. In the National Toxicology Program's (NTP) 7th
Annual Report on Carcinogens (1994), respirable glasswool was classified as reasonably anticipated to be
carcinogenic. Inhalation of crystalline silica (quartz) can cause cancer based on animal data, and IARC
concludes sufficient evidence in humans (Group 1). Prolonged and repeated overexposure to free crystalline
silica dust above the TLV level may cause scarring of the lungs with cough and shortness of breath. A delayed
lung injury, silicosis may result from breathing free silica. OSHA considers fibrous glass dust a nuisance dust.
Fibrous glass can cause dermatitis, local irritation. Fillers are encapsulated and not expected to be released
from product under normal conditions of use.
Target Organs: Skin, Eye, Lung
