ALLOY; SODIUM METAL
IDENTIFICATION:
CAS:
7440-23-5
DOT ID:
UN1428
Hazard Class or Division:
4.3 (DANGEROUS WHEN WET)
ERG Guide:
138
Formula:
Na
RTECS No:
VY0686000
Properties:
Highly
flammable, soft silvery to grayishwhite solid. Shipped or stored under inert
gas or mineral oil. Odorless. Floats and reacts violently with water forming
flammable and explosive hydrogen gas.
Uses:
To make certain alloys; to
purify molten metals; for descaling metal.
HEALTH & SAFETY INFORMATION
•
Non-volatile; contact with water forms corrosive fumes that are irritating to eyes
and respiratory tract. Solid material is a severe eye and skin irritant. Causes
second- and third-degree burns on short contact and is very injurious to the
eyes. Fumes from burning metals are extremely irritating to skin, eyes, nose,
and lungs.
Respirator:
At
any concentrations above the NIOSH REL, or where there is no REL, at any
detectable concentration:
SCBAF:PD,PP
(any self-contained breathing apparatus that has a full facepiece and is
operated in a pressure-demand or other positivepressure mode) SAF:PD,PP:ASCBA
(any suppliedair respirator that has a full facepiece and is operated in a
pressure-demand or other positive-pressure mode in combination with an
auxiliary self-contained breathing apparatus operated in a pressure-demand or
other positive pressure mode).
Escape:
GMFOV
[any airpurifying, full-facepiece respirator (gas mask) with a chin-style,
front-or back-,mounted organic vapor canister] SCBAE (any appropriate
escape-type, selfcontained breathing apparatus).
Reactivity:
Reacts
violently with water, with formation of flammablehydrogen gas and caustic soda
solution. A fire often occurs. Self-reaction may occur in moist air. Strong
reaction with oxidizers, halogens, carbon dioxide, and many hydrocarbon
substances (especially halogenated).
FIRE INFORMATION
Highly
flammable when heated; may ignite spontaneously in air. May react violently
with carbon dioxide or halonogenated extinguishing agents. Containers may
explode in fire. If material or contaminated runoff enters waterways, notify
downstream users of potentially contaminated water.

FIRST AID:
Move
victim to fresh air. Call emergency medical care. Apply artificial respiration
if victim is not breathing. Administer oxygen if breathing is difficult. Remove
and isolate contaminated clothing and shoes. In case of contact with substance,
wipe from skin immediately; flush skin or eyes with running water for at least
20 minutes. Keep victim warm and quiet. Ensure that medical personnel are aware
of the material(s) involved, and take precautions to protect themselves.
