Section III - Hazard Identification
Routes of Exposure: N/A
Summary of Acute Health Hazards: The product presents a very low health risk.
Magnesium hydroxide is a general purpose food additive. Dust generated from the dried
product is classified as a nuisance dust.
Ingestion: Ingestion is unlikely. If ingested in sufficient quantity, may cause
gastrointestinal disturbances. Symptoms may include irritation, nausea, vomiting,
abdominal pain and diarrhea.
Inhalation: May irritate the respiratory tract on prolonged or repeated contact. May
aggravate pre-existing respiratory conditions.
Skin: Repeated or prolonged contact may cause irritation.
Eyes: Particulate is a physical eye irritant.
Summary of Chronic Health Hazards: Dried product dust is classified as a 鈥渘uisance
particulate, not otherwise regulated鈥? as specified by ACGIH and OSHA. The excessive,
long-term inhalation of mineral dusts may contribute to the development of industrial
bronchitis, reduced breathing capacity, and may lead to the increased susceptibility to
lung disease.
Signs and Symptoms of Exposure: N/A
Effects of Overexposure: N/A
Medical Conditions Generally Aggravated by Exposure: Dust from the dried product

Product Name: Thioguard庐 1 (61-65%)
may aggravate pre-existing chronic lung conditions such as, but not limited to, bronchitis,
emphysema, and asthma.
Note to Physicians: N/A
Section IV - First Aid Measures
Ingestion: Ingestion is an unlikely route of exposure. Give 1 - 2 glasses of water and
seek immediate medical attention. Never give anything by mouth to an unconscious
person. Leave decision to induce vomiting for medical personnel, since some particles
may be aspirated into the lungs. Seek immediate medical attention.
Inhalation: Remove victim to fresh air. If not breathing, give artificial respiration. Get
immediate medical attention.
Skin: Wash affected areas with mild soap and water.
Eyes: Flush eyes, including under the eyelids, with large amounts of water. If irritation
persists, seek medical attention.
Section V - Fire Fighting Measures
Flash Point: N/A Autoignition Temperature: N/A
Lower Explosive Limit: N/A Upper Explosive Limit: N/A
Unusual Fire and Explosion Hazards: N/A
Extinguishing Media: Use extinguishing media appropriate to combustibles in area of
fire.
Special Firefighting Procedures: Firefighters should wear NIOSH-approved, positive
pressure, self-contained breathing apparatus and full protective clothing when
appropriate.
Section VI - Accidental Release Measures
Carefully, clean up and place material into a suitable container, being careful to avoid
creating excessive dust from dried product. If conditions warrant, clean up personnel
should wear approved respiratory protection, gloves, and goggles to prevent irritation
from contact and/or inhalation.
Section VII - Handling and Storage
Store at ambient temperature. Prevent possible eye and skin contact by wearing
protective clothing and equipment. Do not store in aluminum tanks. Do not allow product
to freeze.
Section VIII - Exposure Controls/Personal Protection
Respiratory Protection: Respirator approved by NOISH/ MSHA are adequate for
contaminate concentrations encountered in accordance with requirements of 29 CFR
1910.134 for level of exposure incurred.
Ventilation: Provide sufficient ventilation, in both volume and air flow patterns to
control mist/dust concentrations below allowable exposure limits.
Protective Clothing: Gloves are recommended, rubber gloves are recommended when
repeated or prolonged contact is likely. Long sleeve clothing is also recommended.
Eye Protection: Safety glasses are recommended.
Other Protective Clothing or Equipment: N/A
