SECTION I: IDENTIFICATION OF PRODUCT
Workplace Hazard: May cause skin, eye, respiratory and
Proper Shipping Name: Thermasal-B
gastric irritation
Product Name: THERMASAL-B
Product Use: pH control additive
Chemical Family: Proprietary
TDG Classification: Not regulated
WHMIS Classification: Not controlled
Packaging Group: Not applicable
PIN: Not applicable
SECTION II: HAZARDOUS INGREDIENTS
Ingredients Percent CAS Number LD50 (Species/Route) LC50 (Species/Route)
Contains no WHMIS controlled products
SECTION III: TOXICOLOGICAL PROPERTIES
Route of entry: Skin Eye Contact Inhalation Ingestion
Effects of acute exposure: Excessive exposure may cause eye and upper respiratory tract irritation. Particulate is a physical eye
irritant. Prolonged contact may cause skin irritation.
Effects of chronic exposure: Product dust is classified as a 鈥渘uisance particulate, no otherwise regulated鈥? as specified by
ACIGH and OSHA. The excessive, long term inhalation of mineral dusts may contribute to the development of industrial
bronchitis, reduces breathing capacity, and may lead to the increased susceptibility to lung disease.
Exposure limits: OSHA PEL 鈥? 15 mg/m鲁, ACGIH TLV 鈥? 10 mg/m鲁
OSHA: 5 mg/m3 (as PNOR respirable fraction) ; ACGIH : 3 mg/m3 (as PNOC respirable fraction).
Irritancy of product: Excessive exposure may cause eye and upper respiratory tract irritation. Particulate is a physical eye
irritant. Prolonged contact may cause skin irritation.
Sensitization to product: Not determined
Carcinogenicity: None known by NTP, AIRC Monographs, OSHA Regulated
Reproductive toxicity: Not determined
Tetratogenicity: Not determined
Mutagenicity: Not determined
Name of toxicological synergistic products: Not determined

SECTION IV: FIRST AID MEASURES
Skin contact: Wash skin thoroughly with soap and water. Remove contaminated clothing. Get medical attention if any
discomfort continues.
Eye contact: Promptly wash eyes with plenty of water while lifting eyelids. Get medical attention if any discomfort continues.
Inhalation: Move the exposed person to fresh air at once. Get medical attention in any discomfort continues. If not breathing,
give artificial respiration. Get immediate medical attention.
Ingestion: Ingestion is an unlikely route of exposure. If ingested in sufficient quantity and victim is conscious, give 1-2 glasses of
water or milk. Never give anything by mouth to an unconscious person. Leave decision to induce vomiting to qualified medical
personnel, since particles may be aspirated into the lungs. Seek immediate medical attention.

SECTION VI: FIRE AND EXPLOSION DATA
Conditions of flammability: Not combustible
Means of extinguishing:
Product will react with water generating heat. If contact with water is unavoidable, use sufficient water to dissipate any excessive
heat buildup.

Upper flammable limit: Not applicable
Lower flammable limit: Not applicable
Auto-ignition temperature: Not applicable
Hazardous combustion products: Not applicable
Explosion data-sensitivity to mechanical impact: Not applicable
Explosion data-sensitivity to static discharge: Not applicable

SECTION VIII: PREVENTATIVE MEASURES
Personal protective equipment: The use of eye protection, gloves and long sleeve clothing is recommended. For dust
concentrations above allowable nuisance particles limit provide employee with NIOSH /MHSA approved particulate dust
respirator in accordance with the requirements of 29 CFR 1910.134
Specific engineering controls: Provide sufficient ventilation, in both volume and air flow patterns to control mist/dust
concentrations below allowable exposure limits.
Procedures for leak/spills: 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.
Waste disposal: This product does not exhibit any characteristics of a hazardous waste. The product is suitable for landfill
disposal. Follow applicable federal, state/provincial and local regulations for safe disposal.
Handling procedures and equipment: Avoid contamination and wear protective clothing.
Storage requirements: Store in a clean place and keep material dry. Do not allow water to get inside containers; reaction with
water will cause product to swell, generate heat, and burst its container. Exposed, unprotected magnesium oxide will absorb
moisture and carbon dioxide from the air. Minimize dust generation during material handling and transfer.
