MAGNESIUM 239
Hazard: Not pertinent; Buming Rate: Not pertinent.
Chemical Reactivity - Reactivity with Water: Reacts violently with water to produce flammable
hydrogen gas and strong caustic solution; ignition may occur, especially with powder; Reactivity with
Comn Materials: May ignite combustible materials if they are damp; Stability During Transport:
Stable, if air and moisture are excluded; Neutralizing Agents for Acidr and Caustics: Residues should
be washed well with water, then rinsed with dilute acetic acid; Polymerization: Not pertinent; Inhibitor
of Polymerization: Not pertinent.

LITHIUM, METALLIC
Chemical Designations - Synonyms: No common synonyms; Chemical Formula: Li.
Observable Characteristics - Physical State (as shipped): Solid; Color: White; light silvery; Odor:
None.
Physical and Chemical Properties - Physical State at 15 “c and I atm. : Solid; Molecular Weight:
:
6.939; Boiling Point at I am. Not pertinent; Freezing Point: Not pertinent; Critical Temperature: Not
pertinent; Critical Pressure: Not pertinent; Qecijic Gravity: 0.53 at 20 “C (solid); Vapor (Gas) Qecific
Gravity: Not pertinent; Ratio of Specific Heats of Vapor (Gas): Not pertinent; Latent Heat of
Vaporization: Not pertinent; Heat of Combustion: -18,470, -10,260, -429.3; Heat of Decomposition:

Health Hazards Information - Recommended Personal Protective Equipment: Rubber or plastic
gloves; face shield; respirator; fire-retardant clothing; Symptoms Following EKposure: Contact with
eyes causes caustic irritation or burn. In contact with skin lithium react with body moisture to cause
chemical burns; foil, ribbon, and wire react relatively slowly; General Treatment for Exposure: EYES
or SKIN: flush with water and treat with boric acid; Toxicity by Inhalation (Threshold Limit Value):
Data not available; Short-Tenn Inhalation Limits: Data not available; Toxicity by Ingestion: Data not
available; Late Toxicity: Data not available; Vapor (Gas) Irritant Characteristics: Data not available;
Liquid or Solid Irritant Characteristics: Data not available; Odor Threshold Data not available.
Fire Hazards - Flush Point : Not pertinent (combustible solid); FlammabIe Limits in Air (W): Not
pertinent; Fire Extinguishing Agents: Graphite, lithium chloride; Fire Extinguishing Agents Not To Be
Used: Water, sand, halogenated hydrocarbons, carbon dioxide, soda-acid , or dry chemical; ,!$eciaE
Hazards of Combustion Products: Strong alkali fumes are formed in fire; Behavior in Fire: Molten
lithium is quite easily ignited and is then difficult to extinguish. Hot or burning lithium will react with
all gases except those of the helium-argon group. It also reacts violently with concrete, wood, asphalt,
sand, asbestos, and in fact, nearly everything except metal. Do not apply water to adjacent fires.
Hydrogen explosion may result; Ignition Temperature : No data; Electrical Hazard: No data; Burning
Rate: No data.
Chemical Reactivity - Reactivity with Water: Reacts violently to form flammable hydrogen gas and
strong caustic solution. Ignition usually occurs; Reactivity with Common Materials: May ignite
combustible materials if they are damp; Stability During Transport: Stable, if air and moisture are
excluded; Neutralizing Agents for Acids and Caustics: Residues should be flushed with water, then
rinsed with dilute acetic acid; Polymerization: Not pertinent; Inhibitor ofPolymerization: Not pertinent.
