Safety information
DOT Label：
Oxidizer
First Aid：
ERG2024, Guide 140 (Magnesium perchlorate): In Canada, an Emergency Response Assistance Plan (ERAP) may be required for this product. Please consult the shipping paper and/or the "ERAP" section.
Treatment：
In case of oral exposure, immediately dilute with 4 to 8 ounces (120 to 240 mol) of water or milk. Consider after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 1 hour). Protect airway by placement in Trendelenburg and left lateral decubitus position or by endotracheal intubation. Control any seizures first. Maintain ventilation and oxygenation and evaluate with frequent arterial blood gas or pulse oximetry monitoring. Early use of PEEP and mechanical ventilation may be needed. Following inhalation, Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation...
Fire Hazards：
ERG2024, Guide 140 (Magnesium perchlorate): · Runoff may create fire or explosion hazard.
Fire Fighting：
FIRE INVOLVING TANKS, RAIL TANK CARS OR HIGHWAY TANKS: For ammonium nitrate products: Do not fight cargo fire. Withdraw, evacuate and isolate area for at least 1600 meters (1 mile). Treat as an explosive (ERG Guide 112). Do not enter area for 24 hours or until expert advice has been provided. Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. ALWAYS stay away from tanks in direct contact with flames. For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn. (ERG, 2024)
Fire Potential：
It is noncombustible but it will accelerate the burning of combustible materials.
Health Effects：
Adverse effects on a wide variety of organ systems can result from disruption in the availability of T3 to target tissues. Organ systems affected by disturbances in T3 levels include the skin, cardiovascular system, pulmonary system, kidneys, gastrointestinal tract, liver, blood, neuromuscular system, central nervous system, skeleton, male and female reproductive systems, and numerous endocrine organs, including the pituitary and adrenal glands. Such an array of secondary potential targets underscores the need to maintain an adequate level of circulating thyroid hormones. Perchlorate, an environmental contaminant, is known to disturb the hypothalamus-pituitary-thyroid (HPT) axis by blocking iodide accumulation in the thyroid. Iodide deficiency can lead to hypothyroidism and goiter (L894...
Health Hazards：
ERG2024, Guide 140 (Magnesium perchlorate): · Runoff from fire control or dilution water may cause environmental contamination.
Reactive Group：
Oxidizing Agents, Strong
Adverse Effects：
Methemoglobinemia - The presence of increased methemoglobin in the blood; the compound is classified as secondary toxic effect
Cleanup Methods：
IMMEDIATELY REMOVE & CAREFULLY DISPOSE OF ANY SPILLED PERCHLORATE.
Exposure Routes：
Inhalation (L894); oral (L894); dermal (L894); eye contact (L894).
Hazards Summary：
Skin and mucous membrane irritant; Information is limited, but concentrated solutions are probably not irritating; May induce methemoglobinemia after ingestion; [CHEMINFO] Very toxic by ingestion; [CAMEO] A skin, eye, and mucous membrane irritant; [CHRIS] An oxidizing agent that may cause fire on contact with combustible materials; A skin and strong eye irritant; [Alfa Aesar MSDS] See PERCHLORATES.
DOT ID and Guide：
1475 140
Disposal Methods：
SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
Toxicity Summary：
The primary and most sensitive target of the perchlorate anion (perchlorate) is the thyroid gland. Perchlorate inhibits the transport of iodide (I-) from the blood into the thyroid follicle cells. The inhibition is thought to be accomplished by perchlorate competitively blocking iodide binding to a carrier, or sodium/iodide symporter (NIS), which catalyzes the simultaneous transfer of Na+ and I-across the basolateral membrane of thyroid follicle cells. Perchlorate inhibition of the NIS can limit the availability of iodide needed for the production of the thyroid hormones thyroxine (T4) and triiodothyronine (T3), which in turn, may affect the circulating levels of T4 and T3. All known effects of perchlorate on the thyroid hormone system derive directly or secondarily from the inhibition...
Reactivity Alerts：
Strong Oxidizing Agent
Minimum Risk Level：
Chronic Oral: 0.0007 mg/kg/day (L900)
Reactivity Profile：
MAGNESIUM PERCHLORATE is a strong oxidizing agent. Decomposes at 185-190 °C [Hawley]. Noncombustible but accelerates the burning of combustible materials. If large quantities are involved in the fire or the combustible material is finely divided an explosion may result. Avoid contact with mineral acids because of the danger of explosion. In the preparation of anhydrous dimethyl sulfoxide by vacuum distillation from anhydrous magnesium perchlorate, an explosion occurred [MCA Case History 1187, 1966]. Drying ethylene oxide with magnesium perchlorate resulted in an explosion [NSC Newsletter. Chem. Soc. 1959]. Magnesium perchlorate used in drying hydrocarbons exploded when heated to 220 °C [Ind. & Eng. News 17:70. 1939]. As soon as trimethyl phosphite contacted a small amount of magnesium p...
Signs and Symptoms：
Irritating to skin, eyes, and respiratory system, depending on the route of exposure. Esophageal or gastrointestinal tract irritation could occur following exposures (L894).
Storage Conditions：
Keep tightly closed.
Preventive Measures：
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
