Further information
Crystalline silica: Raw materials in this product may contain respirable crystalline silica as an
impurity. Exposures to respirable crystalline silica are not expected during the normal use of this
product. However, actual levels must be determined by workplace hygiene testing. Industrial
hygiene testing by RJ Lee Group showed that cutting with a utility knife or a router equipped with a
dust collection system did not produce airborne respirable crystalline in exceedance of OSHA
PELs. However, cutting with a power saw, even with a dust collection system in place, did produce
some exceedances. Prolonged and repeated exposure to airborne free respirable crystalline silica
can result in lung disease (i.e., silicosis) and/or lung cancer.
Slag Wool Fiber: Large morbidity and mortality studies of both European and North American
mineral wool manufacturing workers have been conducted. These studies have found no
significant association of non-malignant (i.e. fibrosis) or malignant (i.e., lung cancer or
mesothelioma) lung disease and exposures to slag wool fibers and have not established a causal
relationship between exposure and non-malignant or malignant diseases.
In 2001, the International Agency for Research on Cancer (IARC) assigned slag wool fiber to the
Group 3 category [“not classifiable as to carcinogenicity to humans”].
The synthetic mineral fiber used in this product is exonerated from classification as a carcinogen in
accordance with Note Q in the EU Commission Directive 97/69/EC.
Titanium dioxide: Raw materials and/or coatings in this product contain small amounts of titanium
dioxide. The International Agency for Research on Cancer (IARC) has determined that titanium
dioxide is possibly carcinogenic to humans (Group 2B) based on inadequate evidence in humans
and sufficient evidence in experimental animals. This conclusion relates to long-term inhalation
exposure to high concentrations of pigmentary (powdered) or ultrafine titanium dioxide. However,
no significant exposure to primary particles of titanium dioxide is thought to occur during the use of
products in which titanium dioxide is bound to other materials, such as in paints. The available
human studies do not suggest an association between occupational exposure to titanium dioxide
and risk for cancer (1).
The American Conference of Governmental Industrial Hygienists (ACGIH) has designated this
chemical as not classifiable as a human carcinogen (A4).
The US National Toxicology Program (NTP) has not listed this chemical in its report on
carcinogens.
