Skin Irritation
No test data available on the wood panel itself. Data available on identified ingredients
are listed below.
Dermatitis has been reported in humans; nature of the wood and origin of the dust has to
be taken into consideration during cutting or sanding operations of this product.
Eye Irritation
Conjunctivitis has been reported in humans, nature of the wood and origin of the dust has
to be taken into consideration.
Skin Sensitization
No test data available on the wood panel itself. Data available on identified ingredients
are listed below.
Repeated exposure to some species of wood and sensitivity of some workers may cause
the outbreak of some allergies that can become a potential health hazard to these
individuals.
However, considering the small quantity of the resins contained in these products and the
polymerization of these resins during the press cycle, the risk of exposure to
formaldehyde and/or MDI during cutting and sanding operations must be considered of
very low.
Respiratory Sensitization
No test data available on the product itself. Data available on identified ingredients are
listed below.
Inhalation of wood dust may sensitize the respiratory system and cause asthmatic
symptoms and signs.
People with existing respiratory tract ailments, (e.g. bronchitis) should avoid exposures to
wood dust as they may suffer severe irritation and difficulty in breathing.
Some reports suggest that formaldehyde and MDI may cause respiratory sensitization,
such as asthma, and pre-existing respiratory sensitization may be aggravated by
exposure. However, considering the small quantity of the resins contained in these
products and the polymerization of these resins during the press cycle, the risk of
exposure to formaldehyde and/or MDI during cutting and sanding operations must be
considered of very low.
Mutagenicity
No test data available on the product itself. Data available on identified ingredients are
listed below.
Data on wood dust suggests that exposure to wood dust may cause cellular changes in
the nasal epithelium.
