IV.  FIRE AND EXPLOSION HAZARDS DATA

Flash Point: N/A

Autoignition Temperature:  N/A

Explosive Limits:  Lower:  N/A         Upper:  N/A

Extinguishing Media:  Use suitable extinguishing media for surrounding materials and type of fire.

Special Firefighting Procedures:  Firefighters must wear full face, self contained breathing apparatus and full protective clothing to prevent contact with skin and eyes.

Unusual Fire and Explosion Hazards:  When heated to decomposition, lead oxide may emit toxic fumes of lead.  May react with hydrogen peroxide and other strong oxidizers to liberate hydrogen gas.  Explosive reaction with rubidium acetylide at 200 ^oC; zirconium + heat; silicon + aluminum + heat; chlorine + ethylene (at 100 ^oC); perchloric acid + glycerol.  Violent or explosive reaction when heated with aluminum powder.  Violent or explosive reaction with chlorinated rubber (above 200 ^oC); fluoroelastomers (at 200 ^oC); peroxyformic acid.  Violent reaction or ignition with hydrogen trisulfide.  May ignite spontaneously with linseed oil; dichloromethylsilane; fluorine + glycerol.  Vigorous reaction with silicon + heat.  Incandescent reaction with aluminum carbide; lithium acetylide; boron; seleninyl chloride and hydrogen gas.

V.  HEALTH HAZARD INFORMATION

Effects of Exposure:

To the best of our knowledge the chemical, physical and toxicological properties of lead oxide have not been thoroughly investigated and recorded.

Some lead compounds are experimental neoplastigens and tumorigens.  Lead poisoning is one of the commonest of occupational diseases.  The lead must be in such form, and so distributed, as to gain entrance into the body or tissues of the worker in measurable quantity, otherwise no exposure can be said to exist.  Some lead compounds are carcinogens of the lungs and kidneys.  Lead is a cumulative poison.  Increasing amounts build up in the body and eventually reach a point where symptoms and disability occur.  (Sax, Dangerous Properties of Industrial Materials)

Acute Effects:

Inhalation:  May cause irritation to the upper respiratory system, insomnia, dryness of the mouth, and a metallic taste.

Ingestion:  May cause constipation and abdominal pain, colic, tremors, nausea, vomiting, diarrhea, metallic taste, loss of appetite, irritability and muscle pain.  May cause acute lead toxicity.

Skin:  May cause irritation. 

Eye:  May cause irritation.

Chronic Effects:

Inhalation:  May cause chronic lead toxicity.  May be toxic to the central and peripheral nervous system affecting the cerebellum, spinal cord, motor and sensory nerves.

Ingestion:  May cause anemia, gingival lead line, paralysis in the wrist and permanent neurological injury.  May cause chronic lead toxicity.  May cause nephritis, scarring and shrinking of the kidney tissue.

Skin:  No chronic health effects recorded. 

Eye:  No chronic health effects recorded.

Medical Conditions Generally Aggravated by Exposure:  Pre-existing respiratory and circulatory disorders.

Carcinogenicity:  NTP:  No        IARC:  No             OSHA:  No

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION:  Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult, seek medical attention.

INGESTION:  Give 1-2 glasses of milk or water and induce vomiting, seek medical attention.  Never induce vomiting or give anything by mouth to an unconscious person.

SKIN:   Remove contaminated clothing, brush material off skin, wash affected area with soap and water, seek medical attention if symptoms persist.

EYE:  Flush eyes with lukewarm water, including under upper and lower eyelids, for at least 15 minutes.  Seek medical attention if symptoms persist.

Hazardous Decomposition Products:  Lead fumes and hydrogen gas.

Hazardous Polymerization:  Will not occur

VII.  SPILL OR LEAK PROCEDURES

Steps to Be Taken In Case Material is Released or Spilled:  Wear appropriate respiratory and protective equipment specified in section VIII.  Isolate spill area and provide proper ventilation.  Vacuum up spill using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for proper disposal.  Take care not to raise dust.

Waste Disposal Method:  Disposal must be made in accordance with Federal, State, and Local regulations.

VIII.  SPECIAL PROTECTION INFORMATION

Respiratory Protection:  NIOSH approved respirator.

Ventilation:  Use local exhaust to maintain concentration at low exposure levels.  General exhaust is recommended.

Protective Gloves:  Rubber gloves

Eye Protection:  Safety glasses

Other Protective Clothing or Equipment:   Protective gear suitable to prevent contamination.

IX.  SPECIAL PRECAUTIONS

Precautions to Be Taken in Handling and Storage:  Store in a cool, dry area.  Store in tightly closed containers.  Wash throughly after handling.

Work Practices:  Implement engineering and work practice controls to reduce and maintain concentration of exposure at low levels.  Use good housekeeping and sanitation practices.  Do not use tobacco or food in work area.  Wash thoroughly before eating and smoking.  Do not blow dust off clothing or skin with compressed air.  Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.
