Sodium Hydroxide

(caustic soda)

　

 

Potential Acute Health Effects:

Very hazardous in case of skin contact (corrosive, irritant, permeator), of eye contact (irritant, corrosive), of ingestion, of inhalation.

The amount of tissue damage depends on length of contact.

 

Eye contact can result in corneal damage or blindness. Inflammation of the eye is characterized by redness, watering, and itching.

 

Skin contact can produce inflammation and blistering. Skin inflammation is characterized by itching, scaling, reddening, or, occasionally, blistering

　

Inhalation of dust will produce irritation to gastro-intestinal or respiratory tract, characterized by burning, sneezing and coughing. Severe over-exposure can produce lung damage, choking, unconsciousness or death.

　

Potential Chronic Health Effects:

MUTAGENIC EFFECTS: Mutagenic for mammalian somatic cells.

 

The substance may be toxic to mucous membranes, upper respiratory tract, skin, eyes.

 

Repeated or prolonged exposure to the substance can produce target organs damage. Repeated exposure of the eyes to a low level of dust can produce eye irritation. Repeated skin exposure can produce local skin destruction, or dermatitis. Repeated inhalation of dust can produce varying degree of respiratory irritation or lung damage.

 

Slightly explosive in presence of heat.

 

Incompatible materials, moisture, moist air

 

Large Spill:

Corrosive solid. Stop leak if without risk Do not touch spilled material Keep container dry. Do not breathe dust. Never add water to this product.

 

Avoid contact with skin and eyes.

 

Keep away from incompatibles such as oxidizing agents, reducing agents, metals, acids, alkalis, moisture.

 

May cause damage to the following organs: mucous membranes, upper respiratory tract, skin, eyes.

 

Other Toxic Effects on Humans:

Extremely hazardous in case of inhalation (lung corrosive).

 

Very hazardous in case of skin contact (corrosive, irritant, permeator), of eye contact(corrosive), of ingestion,

 

Special Remarks on Chronic Effects on Humans:

 

May affect genetic material. Investigation as a mutagen (cytogenetic analysis)
