                SP. GRAVITY : 1.81

                APPEARANCE: Silver solid.

                MELTING POINT: Approximately 875F. (468C).

                ODOR: No odor.

                pH: Not applicable

 

 IV - FIRE AND EXPLOSION HAZARDS DATA

 

            FLASH POINT: None

                METHOD USED: Not applicable

 

                FLAMMABLE LIMITS

                LFL: Not applicable

                UFL: Not applicable

 

                EXTINGUISHING MEDIA: Smother burning magnesium by covering with an  extinguishing powder approved for use on magnesium fires such as G1, MET-L-X, etc. Consult National Fire Protection

 

                Association standards for other extinguishing media which may be applicable to certain operations such as foundries or heat-treat furnaces.

 

                FIRE & EXPLOSION HAZARDS: When heated in air to a temperature near its melting point, magnesium ignites and burns with a white flame. Use of water on burning magnesium will produce hydrogen gas and may cause an explosion.

 

                FIRE-FIGHTING EQUIPMENT: Wear positive pressure self-contained breathing apparatus.

 

 V - HEALTH HAZARD INFORMATION

               

            EYE: Mechanical injury only.

 

                SKIN CONTACT: Mechanical injury only.

 

                SKIN ABSORPTION: Skin absorption is unlikely due to physical properties.

 

                INGESTION: Ingestion is unlikely due to physical state. If dusts are produced, amounts ingested incidental to industrial handling are not likely to cause injury; however, ingestion of larger amounts could cause serious injury, even death, because the acute oral toxicity of magnesium is considered moderate.

 

                INHALATION: Dust may cause irritation to upper respiratory tract.

 

                SYSTEMIC & OTHER EFFECTS: Exposures incidental to industrial handling are not anticipated to cause any significant adverse effects. Repeated excessive exposure to fumes of aluminum may cause Shaver’s disease (weakness, fatigue and respiratory distress; chest x-rays may reveal fibrosis). Repeated excessive exposure to fumes or dust of a number of metals, including aluminum, may cause central nervous system and developmental effects.

 

                EYES: Irrigate immediately with water for at least 5 minutes.

 

                SKIN: Wash off in flowing water or shower.

 

INGESTION: Induce vomiting if large amounts are ingested. Consult medical personnel.

 

                INHALATION: Remove to fresh air if effects occur. Consult a physician.

 

                NOTE TO PHYSICIAN: No specific antidote. Supportive care.

 

Treatment based on judgment of the physician in response to reactions of the patient.

 

 

 VI - REACTIVITY DATA

 

            STABILITY: ( CONDITIONS TO AVOID) Stable under normal conditions.

           See incompatibility statement.

 

                INCOMPATIBILITY: (SPECIFIC MATERIALS TO AVOID) Acid, water, Reacts with acid to form hydrogen gas. In finely divided form, will react with water and acids to release hydrogen.

 

                HAZARDOUS DECOMPOSITION PRODUCTS: None under normal use or storage. See incompatibility statement and fire and explosion hazard data, Section 3, for special situations.

 

HAZARDOUS POLYMERIZATION: Will not occur.

                                                                                                                              

 

 VII - SPILL OR LEAK PROCEDURES

 

            ACTION TO TAKE FOR SPILLS / LEAKS: Clean off and use.

 

DISPOSAL METHOD: Material can be recycled through secondary scrap recyclers. Contact Rima Industrial for assistance in locating recyclers.

 

 

 VIII - SPECIAL PROTECTION INFORMATION

 

            EXPOSURE GUIDELINE: Magnesium: None established for the metal. For the oxide fume OSHA PEL is 10 mg/m3 total, 5 mg/m3  respirable and ACGIH TLV is 10 mg/m3 . Aluminum: For metals; ACGIH TLV is 10 mg/m3  and OSHA PEL is 15 mg/m3  total, 5 mg/m3  respirable. For fumes, ACGIH TLV and OSHA PEL are 5 mg/m3 . For salts and alkyls; ACGIH TLV and OSHA PEL are 2 mg/m3 .

 

                VENTILATION: Good general ventilation should be sufficient for most conditions. Local exhaust ventilation may be necessary for some operations.

 

                RESPIRATORY PROTECTION: In dusty atmospheres, use na approved dust respirator.

 

                SKIN PROTECTION: Wear clean, long-sleeved, body-covering clothing.

 

                EYE PROTECTION: If dust exposure causes eye discomfort, use chemical goggles.

 

 

 

 IX - SPECIAL PRECAUTIONS

 

            SPECIAL PRECAUTIONS TO BE TAKEN IN HANDLING AND STORAGE: Practice reasonable care in handling this product. Magnesium or magnesium alloy products should be preheated to a minimum temperature of 300 F (149 C) to eliminate moisture prior to use in any melting operation. Water, in any form, if added to molten metal, will quickly generate steam and hydrogen and may cause an explosion. When this magnesium product is melted, or added to a molten bath, proper molten metal handling techniques should always be followed, including personal protective equipment, such as full-body covering flame retardant clothing, hard hat, face shield safety glasses, flame retardant gloves, and steel-toed boots with metatarsal guards.

 

                If operations involving this product, such as machining, produce fines, such as dust, powder, chips, or turnings, proper measures should be taken to prevent dust clouds around these operations. These fines should be collected frequently and should be stored and disposed of in accordance with National Fire Protection Agency guidelines. If these fines should become ignited, they can be extinguished using procedures described in Section 3 of this document.

 

Handle magnesium and magnesium alloy product forms to avoid product damage or personal injury. Store product in dry location. Wet, moist or high humidity storage may lead to corrosion of the product. Store away from other combustible materials
