(50) (50)
Potassium Hydroxide 90% 1310-58-3 365 mg/kg
TOXICOLOGY DATA: Regardless of concentration, the severity of damage and extent of its irreversibility increases with
length of contact time. Prolonged contact with even dilute potassium hydroxide solutions (=>2.0%) can cause a high
degree of tissue destruction. The latent period following skin contact during which no sensation occurs also varies with
concentration.
SECTION III: TOXICOLOGICAL PROPERTIES
ROUTE OF ENTRY: [XX] SKIN [XX] EYE CONTACT [XX ] INHALATION [XX] INGESTION
EYE CONTACT: May cause severe irritation with corneal injury and result impermanent impairment of vision,
even blindness.
SKIN CONTACT: May cause severe burns.

INHALATION: It may cause irritation of mucous membranes of the nose and throat.
EFFECTS OF OVEREXPOSURE: Corrosive to all body tissues with which it comes in contact. The effect of local exposure
may consist of multiple areas of superficial destruction of the skin or of primary irritant
dermatitis. Similarly, inhalation of dust, spray or mist may result in varying degrees of
irritation or damage of the respiratory tract tissues and an increased susceptibility to
respiratory illness. These effects occur only when the TLV is exceeded.
SECTION IV: FIRST AID MEASURES
SKIN CONTACT: Wash exposed portion of skin with water and soap. Remove contaminated clothing and
shoes. Do not reuse until cleaned. Seek medical attention immediately.
EYE CONTACT: OBJECT IS TO FLUSH MATERIAL OUT IMMEDIATELY THEN SEEK MEDICAL
ATTENTION. Water is the only accepted method of removal. Flush eyes with large amount
of water for 15 minutes while holding eyelids open, Seek medical attention. Washing eyes
within several seconds is essential to achieve maximum effectiveness.
INGESTION: Do not give liquids if person is unconscious or very drowsy. Otherwise give no more that 2
glasses of milk or water and SEEK IMMEDIATE MEDICAL ATTENTION. If vomiting occurs
spontaneously, keep airway clear.
INHALATION: If affected, remove person to fresh air immediately. If breathing has stopped, apply artificial
respiration and administer oxygen if necessary. Seek medical attention.

STEPS TO BE TAKEN IN CASE THE MATERIAL IS SPILLED OR RELEASED
ALWAYS SAFETY CLOTHING AND EQUIPMENT. Leaks should be stopped. Spills should be contained and cleaned up
immediately and removed to chemical waste area. Spills should be shovelled up or removed by using a vacuum truck (if
liquid). Neutralize remaining traces of material with any dilute inorganic acid such as hydrochloric, sulphuric, nitric, and
phosphoric and acetic acid. The spill - area should then be flushed with water followed by liberal covering of sodium
bicarbonate. All clean-up material should be removed and placed in approved containers, labelled and stored in a safe
place to await proper treatment or disposal. Spills or releases should be to the appropriate local, provincial and federal
agencies.
WASTE DISPOSAL METHOD
Dissolve slowly in water; carefully neutralize with dilute acid and discharge to chemical waste treatment. Consult federal or
local authorities for proper disposal procedure.
