|Component||CAS#||Approx % by Weight|
Mixture - A trade secret claim is made for this item.
Never give anything by mouth to an unconscious person. If you feel unwell seek medical attention.
Move victim to well ventilated area. If coughing and irritation persists, seek medical attention.
Wash affected area with water. Obtain medical attention if irritation persists.
Remove contact lenses (if present and easy to do). Rince cautiously with water for several minutes.
Obtain medical attention if pain, blinking or redness persists.
Unlikely to be toxic unless large amounts have been ingested. Rinse mouth. Do NOT induce vomiting. If discomfort persists, seek medical attention.
Repeated or prolonged exposure to respirable crystalline silica dust may cause lung damage in the form of silicosis. Symptoms will include progressively more difficult breathing, dry cough, fever, loss of appetite and weight loss, chest pain. Acute silicosis can be fatal.
Prolonged contact with large amounts of dust may cause mechanical irritation.
Prolonged contact with large amounts of dust may cause mechanical irritation.
Inhalation of high concentrations of dry clay dust may cause mechanical irritation and discomfort. Long term exposure may cause chronic effects (see section 11).
Large quantities ingrested may cause gastrointestinal irritation.
Repeated or prolonged exposure to respiriable crystalline silica dust may cause lung damage in for form of silicosis. Symptoms include shortness of breath, fever, fatigue, loss of appetite, chest pain, dry non-productive cough.
This product is not combustible. Use dry chemical or water.
No restrictions on extinguishing media.
Decomposition products include steam (as the product dries), water vapor (as it dehydrates), carbon dioxide, tiny amounts of sulphur (as temperatures exceed 1500F).
Clay can become slippery when wet.
Avoid inhalation of dust during clean-up. Wear approved respirators when dust levels exceed exposure limits. Wet clay is slippery, exercise caution when walking on it.
There are no emergency procedures required for this material.
For normal cleanup, use wet methods (hose, mop) to avoid dust geneation. Use dry methods to collect powdered or granular clay materials only if significant amounts must be collected. Do not use compressed air. Avoid generating dust.
Large cleanups: If needed, evacuate the area downwind during cleanup operations. Collect spilled slurry material using shovels, brooms, squeegees and appropriate containers. Be very cautions of slipping hazards. Water wash to remove any residue.
Clay is a natural material and will not cause adverse effects to most systems. However it can plug pipes and sumps so do not dump muddy water into your drains. Allow it to settle in containers, then pour off the water and dry out the sediment for disposal.
Use proper lifting techniques to avoid physical injury. Wear approved respirators when working in areas where clay products having dust on the packaging are being moved.
Keep pugged clay out of direct sunlight. Do not freeze. Stack pugged material only as high as it will be stable. Keep hallways and passage way floors clean and dust free.

Clay mixture in moist form poses no inhalation health risk. Once clay mixture has dried, there may be dust generated by cleaning and working processes. In the event that dust is generated, use local exhaust ventilation or other engineering controls as required to maintain exposures below applicable occupational exposure limits (TLV).
Exhaust system: When sanding or finishing dry ware, use local exhaust to reduce the level of respirable dust that can be breathed or that will settle on floors and objects.
Respiratory Protection: Respirable dust should be monitored and levels in excess of appropriate exposure limits should be reduced by better ventilation, changing production methods, keeping floors cleaner, periodically cleaning shelves and other objects on which dust settles. When controls are not feasible wear NIOSH/OSHA approved respirators where airborne concentration exceeds PEL, otherwise wear an N95 particulate respirator.
Eye Protection: Use safety glasses where appropriate. Avoid working in areas having crystalline silica dust if you wear contact lenses.
Skin Protection: Protective cloting is not essential. Use gloves and/or protective clothing if abrasion or allergic reactions are experienced.
Moist plastic clay or dry powder
White, grey, brown, red
< 0C (32F)
Not data available
Not soluble in water
No stabilizers required. Safety issue: Mold may form in the plastic bag (moist clay mixture) after several months of shelf life (especially if the material is exposed to sunlight).
Temperatures above 2000F are required for decomposition products other than small amounts of CO2. Possible products are sulfur, metal fumes).
May cause mechanical irritation and discomfort.
Long term repeated and prolonged inhalation of respirable dust may cause damage in the form of silicosis, or, increase susceptibility to bronchitis, COPD, tuberculosis.
Silica has been classified by OSHA as a human lung carcinogen.
Symptoms included progressively more difficult breathing, cough, fever, weight loss. Acute silicosis can be fatal.
Exposure to high levels of dust can irritate the eyes. Preexisting skin sensitivities or allergies can be aggravented by skin contact of dry or wet clay. No known short or long term mutagenic, teratogenic or development effects.
Clays and mineral powders used in this product are inert and insoluble.
Clay particles have an electrolytic affinity for water. As their proportion increases in the soil it becomes more and more impermeable to water penetration.
Refer to section 8.
Standard waste containers - no special requirements.
In accorance with local, state and federal requirements. No special measures. Call your supplier for advice on repurposing specific material to another manufacturing process to eliminate the need for disposal.
When dry clay dust is being transported and workers are exposed to it in confined environments, it should be in sealed containers that do not permit release of dust during handling.
Do not dispose into sinks or toilets. When clay:mineral powder mixes disperse in plenty of water heavier particles quickly settle out and their sticky nature can make it difficult to flush them away.
None. This product is non-combustible.
Not regulated. No UN proper shipping name, transport hazard class, packing group number, bulk transport guidance, special precautions.
Quartz and other materials are listed in the TSCA Chemical Substance Inventory.
The mixture contains no substances at or above the reporting threshhold under section 313, based on available data.
D2A Materials causing other toxic effects.
Components found in this product may contain trace amounts of inherent naturally occuring elements (such as, but not limited to manganese, sulfur).
