Is zeolite hazardous?
Is zeolite hazardous?
Zeolite is of low acute toxicity. Long-term exposure to any respiritible mineral dust could cause slight effects on the respiratory system. Wet Zeolite spillage constitutes a minor slipping hazard. Primary hazards: This product does not present any primary hazards.
What are the properties of erionite?
Erionite is a naturally occurring fibrous mineral that belongs to a group of minerals called zeolites. It usually is found in volcanic ash that has been altered by weathering and ground water….
| Erionite | |
|---|---|
| Luster | Vitreous – silky |
| Streak | white |
| Specific gravity | 2.09 – 2.13 avg = 2.11 |
| Optical properties | Uniaxial (-) |
What is MSDS in chemical safety?
A Material Safety Data Sheet (MSDS) is a document that contains information on the potential hazards (health, fire, reactivity and environmental) and how to work safely with the chemical product. It is an essential starting point for the development of a complete health and safety program.
What happens if you inhale zeolite?
Inhalation May be harmful if inhaled. Causes respiratory tract irritation. Ingestion May be harmful if swallowed. Skin May be harmful if absorbed through skin.
Is zeolite A metal?
Zeolite, any member of a family of hydrated aluminosilicate minerals that contain alkali and alkaline-earth metals. The zeolites are noted for their lability toward ion-exchange and reversible dehydration.
What is erionite used for?
Therefore, the use of other zeolites may result in exposure to erionite among workers and members of the general population who use the zeolites in various processes and products. The commercial uses of other natural zeolites include pet litter, soil conditioners, animal feed, wastewater treatment, and gas absorbents.
Where is erionite found?
Erionite is a naturally occurring, microscopic, fibrous mineral. It usually is found in volcanic ash that has been altered by weathering and ground water. Erionite forms brittle, wool-like fibrous masses in the hollows of rock formations.
When is erionite a hazard to the environment?
Erionite fibers only pose a hazard if they are disturbed and become airborne, and control recommendations should focus on reducing the potential for exposure to airborne erionite fibers.
Are there any commercial uses for erionite zeolite?
Erionite is no longer mined or marketed for commercial purposes. Although other natural zeolites have many commercial uses (pet litter, soil conditioners, animal feed, waste- water treatment, gas absorbents, etc.) because of their unique properties, very few data are available specifically for erionite.
Where do you find erionite in volcanic ash?
Erionite is a naturally occurring mineral that belongs to a group of silicate minerals called zeolites. It is usually found in volcanic ash that has been altered by weathering and ground water.
How much Erionite is in a ton of gravel?
However, bulk gravel erionite concentrations alone are not a reliable predictor of air concentrations, as disturbance of gravels containing erionite in “trace” amounts (< 0.2%) can sometimes result in relatively high airborne fiber concentrations.
