Repeated or prolonged exposure is not known to aggravate medical condition.

 

Section 4: First Aid Measures

 

Eye Contact:

Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Cold water may be used. WARM water MUST be used. Get medical attention if irritation occurs.

 

Skin Contact: Wash with soap and water. Cover the irritated skin with an emollient. Get medical attention if irritation develops.

 

Serious Skin Contact: Not available.

 

Inhalation:

If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.

 

Serious Inhalation: Not available.

 

Ingestion:

Do NOT induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. If large quantities of this material are swallowed, call a physician immediately. Loosen tight clothing such as a collar, tie, belt or waistband.

 

Serious Ingestion: Not available.

 

Section 5: Fire and Explosion Data

 

Flammability of the Product: Non-flammable.

 

Auto-Ignition Temperature: Not applicable.

 

Flash Points: Not applicable.

 

Flammable Limits: Not applicable.

 

Products of Combustion: Not available.

 

Fire Hazards in Presence of Various Substances: Not applicable.

 

Explosion Hazards in Presence of Various Substances:

Risks of explosion of the product in presence of mechanical impact: Not available.

Risks of explosion of the product in presence of static discharge: Not available.

 

Fire Fighting Media and Instructions: Not applicable.

 

Special Remarks on Fire Hazards:

Magnesium Oxide may ignite and explode when heated with sublimed sulfur, magnesium powder, or aluminum powder.

It reacts violently with interhalogens (bromine pentafluoride, chlorine trifluoride) and produces flame. When combined with phosphorus pentachloride, it incandesces.

 

Special Remarks on Explosion Hazards:

Magnesium Oxide may ignite and explode when heated with sublimed sulfur, magnesium powder, or aluminum powder.

 

Section 6: Accidental Release Measures

 

Small Spill:

Use appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and dispose of according to local and regional authority requirements.

 

Large Spill:

Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow to evacuate through the sanitary system. Be careful that the product is not present at a concentration level above TLV. Check TLV on the MSDS and with local authorities.

 

Section 7: Handling and Storage

 

Precautions: Do not breathe dust. Keep away from incompatibles such as oxidizing agents, acids.

 

Storage:

Moisture Sensitive. Air Sensitive. Keep container tightly closed. Keep container in a cool, well-ventilated area.

Do not store above 24C (75.2F).

 

Section 8: Exposure Controls/Personal Protection

 

Engineering Controls:

Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to airborne contaminants below the exposure limit.

 

Personal Protection: Safety glasses. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent.

Gloves.

 

Personal Protection in Case of a Large Spill:

Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist  BEFORE handling this product.

 

Exposure Limits:

TWA: 10 (mg/m3) from ACGIH (TLV) [United States] Inhalation Total.

TWA: 4 STEL: 10 (mg/m3) [United Kingdom (UK)] Inhalation Respirable.

TWA: 15 (mg/m3) from OSHA (PEL) [United States] Inhalation Total.

TWA: 10 (mg/m3) [United Kingdom (UK)] Total.Consult local authorities for acceptable exposure limits.

Section 10: Stability and Reactivity Data

 

Stability: The product is stable.

 

Instability Temperature: Not available.

 

Conditions of Instability: Incompatible materials, moisture, air.

 

Incompatibility with various substances: Reactive with oxidizing agents, acids.

 

Corrosivity: Non-corrosive in presence of glass.

 

Special Remarks on Reactivity:

Reacts violently with ClF3 (Chlorine Trifluoride) and PCl5 (Phosphorous Pentachloride). Hygroscopic. Air Sensitrive. Readily absorbs moisture and carbon dioxide when exposed to air. Hydrates slowly in contact with moisture. Takes up carbon dioxide and water from the air. This happens more readily for the light form vs. the heavy form. Slight alkaline reaction to water.

Special Remarks on Toxicity to Animals: Not available.

 

Special Remarks on Chronic Effects on Humans: May cause cancer (tumorigenic) based on animal data. No human data found.

 

Special Remarks on other Toxic Effects on Humans:

Acute Potential Health Effects:

Skin: Mild Alkali. May cause skin irritation.

Eyes: Mild Alkali. May cause eye irritation.

Inhalation: May cause respiratory tract irritation.

Ingestion: May cause gastrointestinal tract irritation with nausea, vomiting, and diarrhea. `

Chronic Potential Health Effects:
