Following ingestion
Rinse mouth.
4.2 Most important symptoms/effects, acute and delayed
Exposure Routes: inhalation, skin and/or eye contact Symptoms: Irritation eyes, nose; metal fume fever: cough, chest pain, flu-like fever Target Organs: Eyes, respiratory system (NIOSH, 2016)
4.3 Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Magnesium and Related Compounds
