Components
Material:
Methyl
Metacrylate (MMA)
Poly Methyl Metactylate (PMMA)
Alumina Trihydrate (AL-OH3)
Materials are not known to contain toxic materials under Title
III and Reauthorization Act of 1986 and 40 CFR part 372.
Hazards
Identification:
Topstone Solid surface is not hazardous in its original state
but fabricating procedures may generate dust at a high degree
which might result in a release of MMA vapor that could cause
irritation to the eye, nose and throat areas and skin rash.
Inhalation of MMA vapor may cause nausea, shortness of breath,
coughing, lung irritation, increased blood pressure, and abnormal
testing of kidney functions.
Persons with lung disease may have adverse affects when exposed
to dust of MMA.
There is no known carcinogens in this material at levels in
excess of .1% as listed by OSHA or IARC.
First
Aid Measures:
- Inhalation
- No specific action required. If any irritation occurs,
consult a physician.
- Eye
Contact - Flush eyes immediately with ample amounts of fresh
water for at least 20 minutes. Consult a physician.
- Skin
Contact - Wash skin area with soap and warm water.
- Ingestion
- Although the material is unlikely to be hazardous after
ingestion, consult a physician.
Firefighting
Measures :
Pursuant
to NEMA LD3, Topstone is highly resistant to flame, but if exposed
to extremely high temperatures it may be combusted. Hazardous
gases released in fire are methyl methacrlate, carbon monoxide,
and aldehydes. Agents for extinguishing are water, dry chemical
and carbon dioxide. Instructions for firefighting are to keep
personnel upwind and to wear self contained breathing equipment.
Storage
and Handling:
- Avoid
breathing dust or creating dust.
- Work
areas should be clean, dry and well ventilated.
- Work
gloves, work shoes and protective eye goggles should be
worn.
- A protective
face dust mask should be used over the nose and mouth when
engaging power tools.
- Avoid
breathing fumes as a result of fabrication
- Store
in a dry and cool place.
