I discovered that have re-engineered transite and made it completely
safe for the studio.
G’day Karen - I seem to be forever playing the Devil’s advocate -
it’s not a role I enjoy, but … if the material you are talking
about is Transite HT then it’s a calcium silicate insulating board -
here’s a quote from the MSDS issued May 3 2002:
"Primary Routes of Entry: Via respirable dust to the lungs and
respiratory system and via coarse dust and particulate to the eyes.
Primary Target Organs: Lungs, respiratory system and eyes.
Potential Health Effects:
Inhalation: Long term overexposure to respirable crystalline silica
dust may cause permanent and irreversible lung damage including
Skin Contact: Possible dryness or irritation resulting from long
term exposures to product dust.
Eye Contact: A mechanical irritant which can cause moderate to
severe eye irritation.
Ingestion: Non-hazardous when ingested. Potentially a mild irritant
to the GI tract if excessive quantity is ingested.
Medical Conditions Aggravated by ExposuRe: Pre-existing chronic
upper respiratory and lung diseases such as, but not limited to,
bronchitis, emphysema and asthma.
Carcinogenicity: This product contains crystalline silica which is
classified as a class 1, human carcinogen by IARC, as a suspect
carcinogen by NTP and as a possible select carcinogen by OSHA."
All of which just means that you don’t saw it, grind it, file it or
otherwise disturb the surface, not that you don’t use it!
Just that you are aware that there are potential hazards and use it
