caustic soda

• Sodium hydroxide - also known as lye and Caustic
  soda, is the most popular alkali in the world.
  Caustic soda is the fundamental feedstock in
  manufacturing a wide variety of chemical
  compounds. Caustic soda is also used as an
  intermediate and reactant in the production of
  solvents, plastics, synthetic fibers, and
  prescribed drugs. It is also used in neutralizing
  acidic waste streams and scrubbing of acidic
  additives from off-gases.

• Pulp Paper Industry
• Textile Processing
• Soap Detergents Manufacturinglt 0.1 w/w
• Petroleum Products
• Aluminum Metal Manufacturing
• Chemical Process
• Bleach Manufacturing
• Plastic Manufacturing
• Acid Neutralization
• Organic chemicals such as dyes.

Potential Health Effects

• 2. Ingestion

• 1. Inhalation

• Severe irritant. Effects from inhalation of dust
  or mist vary from mild irritation to serious
  damage of the upper respiratory tract, depending
  on the severity of the exposure. Symptoms may
  include sneezing, sore throat or runny nose.
  Severe pneumonitis may occur.

• Corrosive! Swallowing may cause severe burns of
  mouth, throat, and stomach. Severe scarring of
  tissue and death may result. Symptoms may include
  bleeding, vomiting, diarrhea, fall in blood
  pressure. Damage may appear days after exposure.

Potential Health Effects

• 3. Skin Contact

• 4.Eye Contact

• Corrosive! Contact with skin can cause irritation
  or severe burns and scar with greater exposures.

• Corrosive! It irritates eyes, and with greater
  exposures, it can cause burns that may result in
  permanent impairment of vision, even blindness.

Potential Health Effects

• 6. Aggravation of
• Pre-existing Conditions

• 5. Chronic Exposure

• Persons with pre-existing skin disorders or eye
  problems or impaired respiratory function may be
  more susceptible to the effects of the substance.

• Prolonged contact with dilute solutions or dust
  has a destructive effect on the tissue.

7
Precautions for Safe Handling

• Use the smallest possible amounts in designated
  areas with adequate ventilation
• Keep containers closed when not in use
• Transfer solids using tools or equipment, which
  are corrosion resistant

 Proper handling procedures must be followed to
prevent vigorous boiling, splattering or violent
eruption of the diluted solution. Never add water
to caustic. always add caustic soda to water and
provide agitation.

In general, keep solid sodium hydroxide away from
water. Post DO NOT USE WATER signs in the area
of use to prevent accidental contact.
