Sodium Hydroxide 100 1310-73-2 2 mg/m3 Ceiling 2 mg/m3 Ceiling
SECTION III: TOXICOLOGICAL PROPERTIES
ROUTE OF ENTRY: [XX] SKIN [XX] EYE CONTACT [XX ] INHALATION [XX] INGESTION
EYE CONTACT: Major potential hazard 鈥? Beads in the eye can cause severe destruction and blindness.
These effects can occur rapidly affecting all parts of the eye. Mist or dust can cause
irritation with high concentrations causing destructive burns.
SKIN CONTACT: Major potential hazard - Bead or liquid contact with the skin can cause severe burns with
deep lacerations. Contact with dust or mist can cause multiple burns with temporary loss of
hair at burn site. Solutions of up to 4% in water may not cause irritation and burning for
several hours, while 25 - 50% solutions can cause these effects in less than 3 minutes.
INGESTION: Ingestion of sodium hydroxide can cause severe burning and pain in lips, mouth, tongue,
throat and stomach. Severe scarring of the throat can occur after swallowing. Death can
result from ingestion.

INHALATION: Inhalation of dust or mist can cause mild irritation at 2 mg/m3. More severe burns and
tissue damage of the upper respiratory tract can occur at higher concentrations.
Pneumonitis can result from severe exposures.
SECTION IV: FIRST AID MEASURES
SKIN CONTACT: Immediately wash contaminated areas with plenty of water for at least 15 minutes. Remove
contaminated clothing and footwear and wash clothing before reuse. Discard foot wear
which cannot be decontaminated. Treat chemical burns as thermal burns. SEEK
IMMEDIATE MEDICAL ATTENTION.
EYE CONTACT: FLUSH MATERIAL OUT IMMEDIATELY THEN SEEK IMMEDIATE MEDICAL ATTENTION.
Immediately flush eyes with large amounts of water for at least 15 minutes, holding lids apart
to ensure flushing of the entire surface. Washing eyes within several seconds of contact is
essential to achieve maximum effectiveness.
INGESTION: Never give anything by mouth to an unconscious person. If swallowed, DO NOT INDUCE
VOMITING. Give large quantities of water. If available, give several glasses of milk. If
vomiting occurs spontaneously, keep airway clear. SEEK IMMEDIATE MEDICAL
ATTENTION.
INHALATION: Remove to fresh air; if breathing is difficult, have trained person administer oxygen. If
respiration stops, give mouth-to-mouth resuscitation. GET IMMEDIATE MEDICAL
ATTENTION.

PRECAUTIONS TO BE TAKEN IN HANDLING AND STORING
Avoid contact with skin and avoid breathing dust. Do not eat, drink or smoke in work area. Wash hands prior to eating,
drinking, or using bathroom. Any protective clothing, clothing or shoes which become contaminated with caustic should be
removed immediately and thoroughly laundered before re-use.
Store in closed, properly labelled containers indoors in a dry area. Do not remove or deface labels or tags. When
dissolving in water, use warm water but not exceeding 37.7 0C. Slowly add caustic to surface of water with constant
stirring to avoid violent spattering. Full protective equipment as outlined above should be worn. Large amounts of heat will
be evolved. Contact of caustic soda cleaning solutions with food and beverage products in enclosed vessels or spaces
may produce lethal concentrations of carbon monoxide gas. Do not enter confined spaces such as tanks or pits without
following proper entry procedures.
Do not re-use bags, drums or boxes without recycling or reconditioning in accordance with any applicable federal,
provincial or local laws.
STEPS TO BE TAKEN IN CASE THE MATERIAL IS SPILLED OR RELEASED
Cleanup personnel must wear proper protective equipment. Reclaim into closed containers for normal use or disposal.
Remaining material may be diluted with water and neutralized. Neutralization products, both liquid and solid must be
recovered for disposal. Prevent runoff into ground or surface water or sewers. Reportable quantity is 1000 lbs. Notify
Alberta Public
Safety Services (Edmonton: 422-9600 or 1-800-272-9600) of uncontrolled spills in excess of Reportable Quantity.
WASTE DISPOSAL METHOD
Recovered solids or liquids may be sent to a licensed reclaimer or disposed of in a permitted waste management facility.
Consult federal, provincial, or local disposal authorities for approved procedures.
