SECTION 2 ?HAZARDS IDENTIFICATION
WHMIS CLASSIFICATION:
E - Corrosive Material
C - Oxidizing Material
EMERGENCY OVERVIEW:
Corrosive. Causes skin burns. Causes severe eye burns. May be fatal if swallowed.
EFFECTS OF SHORT-TERM (ACUTE) EXPOSURE:
SKIN CONTACT: Direct contact causes irritation and pain. Prolonged contact may cause burns.
EYE CONTACT: Damage can range from severe irritation and mild scarring to blistering, disintegration, ulceration,
severe scarring and clouding. Glaucoma and cataracts are possible late developments.
INGESTION: Causes gastrointestinal irritation with abdominal pain, nausea, vomiting and diarrhea. May cause
gastrointestinal burns.
INHALATION: May cause severe irritation of the gastrointestinal tract with sore throat, coughing, shortness of breath
and delayed lung edema. May cause chemical burns to the respiratory tract.
EFFECTS OF LONG-TERM (CHRONIC) EXPOSURE:
Repeated or prolonged exposure of the skin to low concentrations of liquid can cause drying and cracking. There is no
evidence of carcinogenicity in humans from occupational exposures.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE:
Pre-existing skin disorders.

SECTION 3 ?COMPOSITION
HAZARDOUS INGREDIENTS % (w/w) CAS NUMBER
Sodium Hypochlorite 10 7681-52-9
Sodium Hydroxide (caustic soda) 1.2 1310-73-2
Active Chlorine 12 7782-50-5
SECTION 4 ?FIRST AID MEASURES
SKIN CONTACT: Remove all exposed clothing and wash exposed areas of the body twice with soap and water. Wash
all exposed clothes with soap and water. Get medical attention if irritation persists after the area is washed.
EYE CONTACT: Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain,
swelling, lacrimation or photophobia persist, get medical attention.
INGESTION: Never give anything by mouth if victim is rapidly losing consciousness, or is unconscious or is convulsing.
Have victim rinse mouth thoroughly with water. DO NOT INDUCE VOMITING. Have victim drink 300 mL (10 oz.) of
water. If milk is available, administer AFTER the water. If vomiting ocurrs naturally, have the victim lean forward to
reduce risk of aspiration. Repeat administration of water.
INHALATION: Remove source of contamination or remove victim to fresh air. If breathing is difficult, it may be beneficial
for a trained person to give oxygen. Ensure victim is completely at rest - allow no physical exertion. Obtain medical
attention if symptoms persist.
GENERAL COMMENTS: Provide general supportive measures (comfort, warmth, rest). First-aid procedures should be
reviewed by appropriate personnel familiar with sodium hydroxide and its conditions of use in the workplace.
SECTION 5 - FIRE FIGHTING MEASURES
FLASH POINT: LOWER FLAMMABILITY SENSITIVITY TO
Not applicable Not applicable Not sensitive
LIMITS: MECHANICAL IMPACT:
AUTOIGNITION UPPER FLAMMABILITY SENSITIVITY TO STATIC
Not applicable Not applicable Not sensitive
TEMPERATURE: LIMITS: DISCHARGE:
HAZARDOUS COMBUSTION PRODUCTS: Thermal decomposition at elevated temperatures will release chlorine.
EXTINGUISHING MEDIA: Does not burn but oxidizing materials increase the burning rate of combustible materials. Use
extinguishing agents suitable for the surrounding fire.
FIRE FIGHTING INSTRUCTIONS: Evacuate area and fight fire from a safe distance. Wear adequate personal protective
equipment. Approach fire from upwind. Remove or isolate materials not involved in the fire if it can be done without risk.
Chemical resistant clothing and positive pressure SCBA may be required. Water may be used to keep fire-exposed
containers cool to prevent rupture.
NATIONAL FIRE PROTECTION ASSOCIATION (NFPA) HAZARD INDEX:
Not established
SECTION 6 ?ACCIDENTAL RELEASE MEASURES
PERSONAL PROTECTION: Evacuate unnecessary personnel from spill area. Wear appropriate personal protective
equipment. Ventilate area. Remove chemicals which can react with the spilled material if it can be done without risk. Do
not touch spilled caustic.
MSDS#: 0010 Page 2 of 6
Effective date: 2005/August/18
SODIUM HYPOCHLORITE
ENVIRONMENTAL PRECAUTIONS: Implement spill control plan. Stop or reduce leak if safe to do so. Prevent from
entering sanitary or storm sewers, waterways, or confined spaces by diking with inert materials such as earth or sand.
REMEDIATION MEASURES: Restrict access to area until completion of cleanup. Ensure cleanup is conducted by trained
personnel only. Use all appropriate personal protective equipment. Contain and absorb spill with inert materials. Neutralize
with sodium bicarbonate, agricultural lime or crushed limestone. Notify government occupational health and safety and
environmental authorities as per applicable regulations. In the United States, releases over 100 pounds must be reported to
the National Response Center at 1-800-424-8802.
SECTION 7 - HANDLING AND STORAGE
HANDLING: Take all precautions to avoid personal contact. Keep containers closed when not in use.
STORAGE: Store in a cool, dry, and well ventilated area. Store away from incompatible materials and direct light. Long-
term storage is impossible without decomposition.
SECTION 8 - EXPOSURE CONTROLS AND PERSONAL PROTECTION
EXPOSURE LIMITS:
Sodium Hypochlorite
AIHA WEEL-STEL: 2 mg/ m3 (15 min)
Chlorine
ACGIH TLV-C: 0.5 ppm
ACGIH TLV- STEL: 1.0 ppm
OSHA PEL-TWA: 0.5 ppm
Sodium Hydroxide
2 mg/m3
ACGIH TLV-C:
2 mg/m3 (vacated 1989 OSHA PEL Ceiling limit 2mg/m3 still enforced in some states)
OSHA PEL-TWA:
ENGINEERING CONTROLS: Use general or local exhaust ventilation to maintain exposure below the exposure limits.
These controls may need to be augmented by the use of process or personnel enclosures, control of process conditions, or
by process modification.
RESPIRATORY PROTECTION: Not normally required for most uses. NIOSH recommendations when necessary.
In Brazil, use equipment with certificate of approval emitted by the Ministry of Labour.
SKIN PROTECTION: Wear appropriate chemical protective gloves(rubber or PVC), boots and goggles.
EYE AND FACE PROTECTION: Chemical safety goggles are recommended. A full face shield may also be necessary
depending of contact potential. The wearing of contact lenses is not recommended.
OTHER: Have a safety shower and eye wash station readily available in the immediate work area.
