Data on Fire and Explosion Hazards:
Flash Point: NONE
Lower Explosive Limit: UNKNOWN
Upper Explosive Limit: UNKNOWN
Extinguishing Media: FIRES SHOULD BE SMOTHERED WITH DRY GRAPHITE, TALCUM, DRY SAND OR CLASS D METAL FIRE EXTINGUISHERS. DO NOT USE FOAM, HALOGENATED AGENTS OR CO2.
Special Firefighting Measures: WHEN FIGHTING FIRES, WEAR RESPIRATORY APPARATUS AND PROTECTIVE CLOTHING. USE OF WATER ON MELTED OR BURNING MAGNESIUM MAY RESULT IN THE FORMATION OF HYDROGEN GAS, WHICH CAN LEAD TO EXPLOSION.
Unusual Fire and Explosion Hazards: FINE POWDER IS EASILY IGNITABLE AND BURNS WITH HIGH HEAT AND A BRIGHT WHITE FLAME; EYE PROTECTION SHOULD BE WORN. THE POWDER CAN FORM EXPLOSIVE MIXTURES WITH AIR.

Data on Reactivity:
Stability: YES
Conditions to Avoid (Stability): MAGNESIUM POWDER MAY IGNITE IN AIR AT TEMPERATURES BELOW 900F.
Substances to Avoid: OXIDISING AGENTS, MOISTURE AND ACIDS. MAGNESIUM REACTS WITH WATER OR ACIDS TO PRODUCE HYDROGEN.
Hazardous Decomposition Products: MAGNESIUM OXIDE.
Hazardous Polymers: NO
Conditions to Avoid (Poly): NOT APPLICABLE

Data on Health Hazards:
LD50/LC50 Mixture: TLV IS 430 MG/ DAY
Exposure Route - Inhalation: YES
Exposure Route - Dermal: NO
Exposure Route - Ingestion: NO
Acute and Chronic Health Hazards: ACUTE: EXPOSURE TO MAGNESIUM METAL OR OXIDE DUST POSES A LOW HEALTH RISK WHEN INHALED. EXPOSURE TO MAGNESIUM OXIDE FUMES MAY LEAD TO METAL FUME FEVER. CHRONIC: NO INFORMATION PROVIDED BY THE MANUFACTURER.
Carcinogenicity - NTP: NO
Carcinogenicity - IARC: NO
Carcinogenicity - OSHA: NO
Carcinogenicity Explanation: THERE ARE NO INGREDIENTS ABOVE 0.1% THAT HAVE BEEN IDENTIFIED AS CARCINOGENIC BY NTP, IARC OR OSHA.
Symptoms of Overexposure: EYES: CORNEAL ABRASION. INHALATION: TRANSIENT SYMPTOMS OF METAL FUME FEVER INCLUDING FEVER, CHILLS, NAUSEA, VOMITING AND MUSCLE ACHES. MAGNESIUM METAL OR OXIDE DUST IS MERELY A NUISANCE.
Medical Conditions Aggravated by Exposure: PERSONS WITH A HISTORY OF RESPIRATORY CONDITIONS MAY BE AT GREATER RISK.
Emergency/First Aid Measures: EYES: DO NOT RINSE WITH WATER. REMOVE PARTICLES WITH A WET COTTON SWAB. INHALATION: MOVE THE VICTIM TO FRESH AIR. SYMPTOMS TYPICALLY OCCUR 4-12 HOURS AFTER EXPOSURE. RECOVERY IS USUALLY COMPLETE WITHIN 24-48 HOURS. INGESTION: NO HAZARD. INDUCE VOMITING.

Precautions for Safe Handling and Use:
Spill/Release Procedures: USE A RESPIRATORY MASK. AVOID GENERATING DUST. USE NON-SPARKING TOOLS. CAREFULLY SWEEP UP CLEAN, DRY POWDER TO MINIMISE DUST AND TRANSFER IT TO CLEAN, SEALABLE CONTAINERS. WET OR CONTAMINATED MATERIAL SHOULD BE TRANSFERRED TO A WELL-VENTILATED CONTAINER AND MOVED TO AN ISOLATED AREA.
Neutralising Agents: NOT APPLICABLE
Waste Disposal Method: NOTIFY LOCAL ENVIRONMENTAL AUTHORITIES. STORE IN SEALED CONTAINERS UNTIL DISPOSAL IS ARRANGED. DISPOSE IN ACCORDANCE WITH FEDERAL, STATE AND LOCAL REGULATIONS.
Handling/Storage Precautions: ALL HANDLING AND TRANSFER OPERATIONS MUST BE GROUNDED. STORE IN DOT-APPROVED CONTAINERS. AVOID DIRECT VIEW OF MAGNESIUM FIRES, AS THIS MAY CAUSE EYE INJURY.
Other Precautions: REGULAR MEDICAL EXAMINATIONS ARE RECOMMENDED FOR PERSONS FREQUENTLY EXPOSED TO DUST.

Control Measures:
Respiratory Protection: IF TLV IS EXCEEDED, USE A NIOSH/MSHA-APPROVED RESPIRATOR WITH A DUST CARTRIDGE.
Ventilation: USE LOCAL EXHAUST VENTILATION TO KEEP EXPOSURE LEVELS BELOW THE TLV.
Protective Gloves: PROTECTIVE GLOVES.
Eye Protection: SIDE-SHIELDED SAFETY GLASSES OR GAZE.
Other Protective Equipment: NONE.
Hygienic Work Practices: REGULAR CLEANING AND GOOD HOUSEKEEPING ARE ESSENTIAL.
Additional Safety and Health Information: NONE.
