HEALTH HAZARD INFORMATION
Skin No adverse effects expected but may cause minor skin
irritation.
Eyes No adverse effects expected but dust may cause mechanical
irritation.
Inhalation Dust may be slightly irritating. Sore throat or coughing may
occur.
Swallowing Since magnesium salts are slowly absorbed, abdominal pain,
vomiting and diarrhea may be the only symptoms. However, if
elimination is blocked by bowel blockage or other reasons,
CNS depression, lack of reflexes, hypocalcemia (deficiency of
calcium in the blood) may occur.

FIRST AID MEASURES
Swallowing Give several glasses of water to drink to dilute. If large
amounts were swallowed, get medical advice.
Skin Remove any contaminated clothing. Wash skin with soap and
water for at least 15 minutes. Get medical attention if irritation
develops or persists.
Eyes Wash thoroughly with running water. Get medical advice if
irritation develops.
Inhalation Remove to fresh air. Get medical attention for any breathing
difficulty.
Note to Physician IV administration of calcium gluconate will partially reverse
the effects of acute magnesium toxicity. Ventricular support
with calcium chloride infusion and mannitol forced diuresis
has also been successful.
EXPOSURE CONTROLS AND PERSONAL PROTECTION INFORMATION
Skin Protection: Wear protective gloves and clean body-covering
Personal Protective Equipment
clothing.
Eye Protection: Use chemical safety goggles. Maintain eye wash
fountain and quick-drench facilities in work area.
A system of local and/or general exhaust is recommended to keep
Ventilation
employee exposures as low as possible. Local exhaust ventilation is
generally preferred because it can control the emissions of the
contaminant at its source, preventing dispersion of it into the general
work area. Please refer to the ACGIH document, Industrial
Ventilation, A Manual of Recommended Practices, most recent
edition, for details.

For conditions of use where exposure to dust or mist is apparent and
engineering controls are not feasible, a particulate respirator (NIOSH
type N95 or better filters) may be worn. If oil particles (e.g.
lubricants, cutting fluids, glycerine, etc.) are present, use a NIOSH
type R or P filter. For emergencies or instances where the exposure
levels are not known, use a full-face positive-pressure, air-supplied
respirator. WARNING: Air-purifying respirators do not protect
workers in oxygen-deficient atmospheres.
Airborne Exposure Limits: None established.
