3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW:
DANGER! Corrosive - Causes severe burns to eyes and skin. May cause irreversible eye damage.
Inhalation of dust is highly irritating and possibly corrosive to the upper respiratory tract. Harmful or
fatal if inhaled. Harmful or fatal if swallowed.
Environmental Hazard -- This product is toxic to fish. Keep out of lakes, streams, ponds, or other
waters.
Precautions: Do not get in eyes, on skin, or on clothing. Corrosive to skin. Even a small amount
in the eye can cause blindness. Do not breathe dust or mists from solutions. Use only with adequate
ventilation. Ventilation must be sufficient to limit employee exposure to this product below permissible
exposure limits. Do not swallow. When making solutions or diluting, only add caustic soda slowly to
surface of cold water while stirring. Do not add to warm or hot water, a violent eruption or explosive

reaction can result. Avoid contact with organic materials and concentrated acids - may cause violent
reactions. Caustic soda reacts with magnesium, aluminum, zinc (galvanized), tin, chromium, brass
and bronze, generating hydrogen which is explosive. Caustic soda may react with various sugars to
generate carbon monoxide. Hazardous carbon monoxide gas can form upon contact with food and
beverage products in enclosed vessels and can cause death. Wash thoroughly after handling.
Remove and wash contaminated clothing before reuse. Do not eat, drink or smoke in work area.
4. FIRST AID MEASURES
INHALATION: Remove from area to fresh air. If symptomatic, contact a poison control center,
emergency room or physician for treatment information.
EYE/SKIN CONTACT: EYE: Remove contact lens and pour a gentle stream of warm water
through the affected eye for at least 15 minutes. Contact a poison control center, emergency room or
physician right away as further treatment will be necessary. SKIN: Run a gentle stream of water over
the affected area for 15 minutes. A mild soap may be used if available. Contact a poison control
center, emergency room or physician right away as further treatment will be necessary.
INGESTION: Gently wipe or rinse the inside of the mouth with water. Sips of water may be given
if person is fully conscious. Never give anything by mouth to an unconscious or convulsing person.
Do Not induce vomiting. Contact a poison control center, emergency room or physician right away as
further treatment will be necessary.
5. FIRE-FIGHTING MEASURES
FLASH POINT: None
EXTINGUISHING MEDIA: Not applicable.
SPECIAL FIREFIGHTING PROCEDURES: Contact with some metals (particularly magnesium,
aluminum and galvanized zinc) can rapidly generate hydrogen, which is explosive. Emits toxic fumes
under fire conditions. Fire-fighters must wear NIOSH approved pressure demand, self-contained
breathing apparatus and full protective clothing when fighting chemical fires.
6. ACCIDENTAL RELEASE MEASURES
ACTION TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED:
Only trained personnel equipped with NIOSH approved, full facepiece combination dust/mist
respirators should be permitted in area. For dry material, use appropriate methods, shovels, brooms,
and vacuums to clean up the spill. If mixed with water, or likely to become mixed with water or any
liquid, dike area to contain spill. Reclaim if possible. Or, dilute spill with large amounts of water then
neutralize with dilute acid. Use vacuum truck to pick up neutralized material for proper disposal.
Properly neutralized liquid residues (pH 6 to 9) may be disposed of in waste water treatment facilities
which allow the discharge of neutral salt solutions. After all visible traces have been removed, flush
area with large amounts of water.
7. HANDLING AND STORAGE

PRECAUTIONS TO BE TAKEN DURING HANDLING AND STORAGE:
Wear appropriate personal protective equipment when handling this product. Never touch eyes or
face with hands or gloves that may be contaminated with this product. When making solutions or
diluting, only add caustic soda slowly to surface of cold water while stirring. Do not add to warm or
hot water, a violent eruption or explosive reaction can result. Avoid contact with organic materials and
concentrated acids - may cause violent reactions. Caustic soda reacts with magnesium, aluminum,
zinc (galvanized), tin, chromium, brass and bronze, generating hydrogen which is explosive. Caustic
soda may react with various sugars to generate carbon monoxide. Hazardous carbon monoxide gas
can form upon contact with food and beverage products in enclosed vessels and can cause death.
Follow appropriate tank entry procedures (see ANSI Z117.1 - 2003 Safety Requirements for Confined
Spaces). Do not enter a storage tank or container (truck or rail) that has contained this product, even
if it appears empty. Store in a cool, dry, well-ventilated place. Store indoors. Keep container closed
when not in use.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Exposure Limits:
8-hour Time Weighted Average (TWA); 15-minute Short-Term Exposure Limit (STEL)
OSHA: The OSHA exposure limit(s) for Sodium Hydroxide: 2 mg/m3 Ceiling.
ACGIH: The ACGIH exposure limit(s) for Sodium Hydroxide: 2 mg/m3 Ceiling.
The Ontario Exposure limit(s) for Sodium Hydroxide: 2 mg/m3CEV
ONTARIO:
RESPIRATORY PROTECTION: Where the potential for exposure exists use the appropriate
regulatory compliant particulate filter respirator with full facepiece. Carefully read and follow the
respirator manufacturer's instructions and information.
VENTILATION: Use local exhaust sufficient to maintain dust/mist levels below permissible
exposure limits.
EYE AND FACE PROTECTION: Close fitting chemical safety goggles with faceshield.
PROTECTIVE GLOVES: Nitrile. Neoprene. Natural rubber.
OTHER PROTECTIVE EQUIPMENT: Boots, aprons, or chemical suits should be used when
necessary to prevent skin contact.
