Physical and Chemical Properties

Appearance

Odorless colorless liquid. An aqueous solution.

Solubility in water

Soluble

Density

1.75 g/cm3 (20 C)

Usage

Electroplating soln for coating metal objects with lead, curing agent for epoxy resins, catalyst in production of linear polyesters.

First Aid Measures

Ingestion

Acute exposure - activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents. Consider gastric lavage in patients with recent ingestion of liquid or powdered products.

Inhalation

Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.

Skin

Wash area with soap and water; treat as an acid burn.

Eyes

Flush with copious quantities of water for 15 min.

Handling and Storage

Storage

Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.

Handling

All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.

Hazards Identification

Inhalation

Respirations are first stimulated then depressed. Death is usually from respiratory paralysis. Following inhalation, coughing and choking may be noted.

Skin

Urticaria and pruritus have been reported following exposure to fluoride.

Eyes

See Inhalation.

Ingestion

Chronic lead exposure: abdominal pain, nausea, anorexia, vomiting, constipation, diarrhea, and a metallic taste in the mouth have been reported with chronic toxicity. Severe and paroxysmal colic characterized by a rigid and retracted abdomen may occur.

Exposure Controls/Personal Protection

Personal Protection

Wear appropriate protective gloves, clothing and goggles.

Respirators

Wear positive pressure self-contained breathing apparatus (SCBA).

Exposure Effects

Chronic lead exposure may cause elevated blood pressure and gout. In young children, developmental defects, including learning disabilities and behavioral abnormalities, can occur without symptoms at blood lead levels above 10 micrograms/deciliter. At higher levels of exposure headache, fatigue, irritability and malaise may occur. At high levels, encephalopathy, seizures and focal neurologic findings with imminent risk of death, permanent mental retardation, and motor deficits may occur. Lead is transferred across the placenta. It can affect reproduction in males and females, and affects neurodevelopmental milestones in children with both prenatal and postnatal exposure.

Exposure limit(s)

TLV (as Pb): ppm; 0.05 mg/m3 A3 (ACGIH 1996). MAK: ppm; 0.1 mg/m3; as Pb (1996).

Fire Fighting Measures

Fire Fighting

SMALL FIRES: Dry chemical, carbon dioxide or water spray. LARGE FIRES: Water spray, fog or regular foam. Move containers from fire area if you can do it without risk. Dike fire control water for later disposal; do not scatter the material. Use water spray or fog; do not use straight streams. FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn.

Fire Potential

Nonflammable.

Accidental Release Measures

Small spills/leaks

Neutralizing Agents for Acids and Caustics: Flush with water, rinse with dilute solution of sodium bicarbonate or soda ash.

Stability and Reactivity

Stability

Stable.

Decomposition

When heated to decomposition it emits very toxic fumes of lead, hydrogen fluoride and boron oxides.

Combustion Products

Toxic and irritating hydrogen fluoride gas may form in fire.
