=====================  Hazards Identification  =====================

LD50 LC50 Mixture:NO DATA PROVIDED BY RESPONSIBLE PARTY.
Health Hazards Acute and Chronic:EXPOSURE TO MAGNESIUM METAL OR OXIDE
    DUST SHOULD BE A LOW HEALTH RISK BY INHALATION AND SHOULD BE
    TREATED AS A NUISANCE DUST. EXPOSURE TO MAGNESIUM OXIDE FUME
    SUBSEQUENT TO BURNING, WELDING, MOLTEN ME TAL WORK, ETC. CAN RESULT
    IN METAL FUMEFEVER. TEMPORARY SYMPTOMS CAN INCLUDE FEVER, CHILLS,
    NAUSEA, VOMITING, AND MUSCULAR PAIN. ONSET OF SYMTPOMS OCCURS 4-12
    HOURS AFTER EXPOSURE. RECOVERY IS USUALLY  COMPLETE IN 24-48 HOURS.
    MEETING THE EXPOSURE LIMITS OF 10 MG/M3 MGO FUME, 5 MG/M3
    (RESPIRABLE) SHOULD PREVENT METAL FUME FEVER FROM OCCURING.
Explanation of Carcinogenicity:NO DATA PROVIDED BY RESPONSIBLE PARTY.
Effects of Overexposure:EXPOSURE TO MAGNESIUM OXIDE FUME CAN RESULT IN
    FEVER, CHILLS, NAUSEA, VOMITING, AND MUSCULAR PAIN.
