HEALTH HAZARD INFORMATION
Health Effects:
Acute
Swallowing sodium hydroxide may cause severe burns of the mouth, throat, esophagus and
Swallowed:
stomach. Death may result. Severe scarring of the throat may occur on recovery after
swallowing sodium hydroxide. An increased number of esophageal cancer cases have been
reported to occur in individuals who have scarring of the esophagus from swallowing sodium
hydroxide.
Sodium hydroxide is destructive to eye tissues on contact. Will cause severe burns that result in
Eye:
damage to the eyes and even blindness. Contact lenses should not be worn when working with
this chemical.
Contact of the skin may cause skin irritation and, with greater exposure, severe burns with
Skin:
scarring.
Effects from inhlation of the dusts, mists or spray will vary from mild irritation to destructive
Inhaled:
burns depending on the severity of exposure. Severe pneumonitis may occur.
The chronic local effect may consist of multiple areas of superficial destruction of the skin or
Chronic:
primary irritant dermatitis. Similarly, inhalation of dust, spray or mist may result in varying
degrees of irritation or damage to the respiratory tract tissues and increased susceptibility to
respiratory illness.
First Aid:
DO NOT induce vomiting. Have conscious person drink several glasses of water or milk. Seed
Swallowed:
immediate medical attention. Serious ingestion: DO NOT induce vomiting. Examine the lips
and mouth to ascertain whether the tissues are damaged, a possible indication that the toxic
material was ingested;l the absence of such signs, however, is not conclusive. Loosen tight
clothing such as collar, tie, blt or waistband. If the victim is not breathing, perform mouth-to-
mouth resuscitation. Seek medical attention.
Check for and remove any contact lenses. IMMEDIATELY flush eyes with running water for at
Eye:
least 15 minutes, keeping eyelids open. Rinse with a dilute solution of boric acid. Finish by
rinsing thoroughly with running water to avoid a possible infection. COLD water may be used.
If the chemical got onto the clothed portion of the body, remove the contaminated clothes as
Skin:
quickly as possible, protecting you own hands an body. Place the victim under a deluge shower.
If the chemical touches the victim's exposed skin such as the hands, neutralise exposed skin
with a dilute solution of boric acid or acetic acid. Gently and thoroughly was the contaminated
skin with running water and non-abrasive soap. Be particularly careful to clean folds, crevices,
creases and groin. COLD water may be used. If irritation persists, seek medical attention. Wash
contaminated clothing before reusing. Serious skin contact: Wash with a disinfectant soap and
cover the contaminated skin with an anti-bacterial cream. Seek medical attention.
Allow the victim to rest in a well-ventilated area. Seek immediate medical attention. Serious
Inhaled:
inhalation: Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as
a collar, tie, belt or waistband. If breathing is difficult, administer oxygen. If the victim is not
breathing, perform mouth-to-mouth resuscitation. WARNING: It may be dangerous to the
person providing aid to give mouth-to-mouth resuscitation when the inhaled material is toxic,
infectious or corrosive. Seek immediate medical attention.

First Aid Facilities:
PRECAUTIONS FOR USE
Exposure Standards: 2 mg/m3
Provide local exhaust
Engineering
Controls:
Employees should be provided with and required to use impervious clothing, gloves, face shield
Personal Protection:
(200mm minimum) and other appropriate protective clothing necessary to prevent any
possibility of skin contact with solutions of sodium hydroxide. Materials suggested for use are
natural rubber, neoprene or vinyl. Employees should be provided with and required to use dust-
and splash-proof safety goggles where there is any possibility of sodium hydroxide contacting
the eyes.
Not flammable under conditions of use.

SAFE HANDLING INFORMATION
Alkalis may be stored in heavy-duty gauge steel containers. Corrosive materials should be
Storage and
stored in a separate safety storage cabinet or room.
Transport:
SMALL SPILL: Dilute with water and mop up, or absorb with an inert DRY material and place
Spills and Disposal:
in an appropriate waste disposal container. If necessary: neutralise the residue with a dilute
solution of acetic acid.
LARGE SPILL: Corrosive liquid. Stop leak if without risk. Absorb with DRY earth, sand or
other non-combustible material. DON NOT get water inside container. DO NOT touch spilled
material. Use water spray curtain to divert vapour drift. Prevent entry into sewers, basements or
confined areas; dike if needed. Call for assistance on disposal. Neutralise the residue with a
dilute solution of acetic acid.
This product is not combustible. Water spray, foam, carbon dioxide or dry chemicals may be

used where this product is stored.
Hazard:
OTHER INFORMATION
Contact with water, acids, flammable liquids and organic halogen compounds, especially
Incompatibilities
trichloroethylene, may cause fires and explosions. Contact with metals such as aluminium, tin,
(Materials to avoid)
zinc and alloys containing these metals causes formation of flammable hydrogen gas. Contact
with nitromethane and other similar nitro comopounds causes formation of shock-sensitive
salts.
