high concentrations of dust may cause mechanical irritation and
discomfort of the respiratory tract . Repeated exposure may have chronic
effects.
(H316 + H320 + H335) Can cause skin, respiratory , and eye irritation .

Section 5 - Fire Fighting Measures
General Fire Hazards Clay mixture in dry or moist form is not flammable and does not support fire. The
paper bags or plastic bags and cardboard boxes containing the mixture are
flammable.
Extinguishing Media Use appropriate extinguishing media for surrounding fire.
Chemical hazards
from fire
Clay mixture does not contain hazardous decomposition products .
Protective actions
and equipment for
fire-fighters
Clay mixture and packaging can become slippery when wet . Fire-fighters should
wear appropriate protective equipment .

and Personal
Protective Equipment
Environmental
Precautions
Emergency procedures
& Methods of
Containment
If appropriate, use gentle water spray to wet down and minimize dust generation .
Wear appropriate protective equipment and clothing during clean-up. When dry
sweeping use NIOSH approved respirators when dust levels exceed exposure
limits.
Clay is a natural mineral product mixture and will not cause adverse effects to the
water system other than turbidity from suspended particles.
There are no emergency procedures required for this mixture. Place dry clay dust
in a sealed container for re-use or proper disposal.
Section 7 - Handling & Storage
Precautions for safe
handling
Recommendations on
the conditions for safe
storage
Use proper lifting techniques to avoid physical injury .
No special storage considerations . Do not store moist clay mixture
below freezing point (< 0 C or<32 F).

Respiratory
Eyes
Skin and Body
Use of NIOSH/OSHA approved safety glasses with side shields is recommended . Face shields
should also be used when dry sawing clay products . Wear tight fitting dust goggles when
excessively (visible) dusty conditions are present or are anticipated. NIOSH recommends that
contact lenses not be worn when working with crystalline silica dust.
Dust is generated when working with dry clay mixture . To minimize exposure to dust and/or
crystalline silica, cutting or sanding dry clay products should be conducted with sufficient
ventilation. Respirable dust and quartz levels should be monitored regularly. Dust and quartz
levels in excess of appropriate exposure limits should be reduced by feasible engineering
controls, including (but not limited to) wet sanding, wet suppression, ventilation, and process
enclosure. When such controls are not feasible, NIOSH/MSHA approved respirators must be
worn in accordance with a respiratory protection program which meets OSHA requirements
as set forth at 29 CFR1910.134 and ANSI Z88.2-1080 " Practices for Respiratory Protection .
In most cases, a disposable N-95 Particulate Respirator is sufficient.
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).
Protective Clothing is not essential . Use gloves and /or protective clothing if abrasion or
allergic reactions are experienced.

Section 11 - Toxicological Information
Primary Route of Exposure: Skin, Eye Contact, Inhalation and Ingestion
Specific Organ Toxicity - Single Exposure
Target organs include ears, skin, respiratory system , and gastrointestinal tract .
Specific Organ Toxicity - Repeated Exposure
Causes damage to eyes , skin, respiratory system , and gastrointestinal tract through prolonged or repeated exposure .
Acute Short-Term Exposure Effects
May cause eye irritation, skin irritation, respiratory tract irritation, and gastrointestinal tract irritation . Inhalation of
high concentrations of dry clay dust may cause mechanical irritation and discomfort . Long term exposure may cause
chronic effects.
Chronic Long Term Exposure Effects
Silica has been classified by OSHA as a human lung carcinogen. Repeated or prolonged exposure of respirable
crystalline silica dust may cause lung damage in the form of silicosis .
Effects of silicosis include bronchitis/chronic obstructive pulmonary disorder , increased susceptibility to tuberculosis ,
scleroderma (a desease affecting skin, blood vessels , joints and skeletal muscles ), and possible renal disease. Acute
silicosis can be fatal.
Related Symptoms
Symptons will include shortness of breath, fever, fatigue, loss of appetite, chest pain, dry non-productive cough .
Medical Conditions Aggravated by Exposure:
Individuals with pre-existing allergies, eye disorders, skin disorders, respiratory disorders and /or gastrointestinal
disorders may have increased susceptibility to the effects of exposure .
