First Aid MeasuresBack to Contents
【Ingestion】

Activated charcoal does not effectively adsorb magnesium salts. Monitor ecg and vital signs frequently. Cardiovascular and/or respiratory assistance may be required. Calcium - to temporarily ameliorate respiratory depression, administer iv calcium chloride 10% (dose: 0.2 To 0.5 Ml/kg/dose up to 10 ml/dose over 5 to 10 minutes). Monitor ecg during infusion and stop if heart rate begins to decrease. Repeat dose if needed. Hypotension: infuse 10 to 20 ml/kg isotonic fluid, place in trendelenburg position. If hypotension persists, administer dopamine (5 to 20 mcg/kg/min) or norepinephrine (0.1 To 0.2 Mcg/kg/min), titrate to desired response. Hypothermia - place patient under a warming blanket or a hugg-bear or equivalent device. Hemodialysis - is the most effective method to remove significant quantities of magnesium and may reverse life-threatening symptoms within 30 minutes.
【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 as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
【Skin】

Remove contaminated clothing, wash exposed area with copious amounts of water. A physician should examine the area if irritation or pain persists.
【Eyes】

Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility. Medical facility: irrigate with sterile 0.9% Saline for at least an hour.
Handling and StorageBack to Contents
【Storage】

Exposure Controls/Personal ProtectionBack to Contents
【Personal Protection】

Wear appropriate protective gloves, clothing and goggles.
【Respirators】

Wear positive pressure self-contained breathing apparatus (SCBA).
【Exposure Effects】

Lethargy, hyporeflexia, weakness, and subjective feeling of thirst and heat may occur. Excessive absorption of magnesium from cathartics may result in CNS depression and seizures, most notably in renal failure patients.

【Fire Potential】

Dangerous fire risk.
Accidental Release MeasuresBack to Contents
【Small spills/leaks】

ELIMINATE all ignition sources and prevent contact. Stop leak if you can do it without risk. Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact spilled material. However DO NOT GET WATER on spilled substance or inside containers. Cover with DRY earth, DRY sand, or other non-combustible material followed with plastic sheet to minimize spreading or contact with rain. For powers, cover with plastic sheet or tarp to minimize spreading and keep powder dry. DO NOT CLEAN-UP OR DISPOSE OF, EXCEPT UNDER SUPERVISION OF A SPECIALIST.
