Hazards and Protection.
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.
Protection
Wear appropriate protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary.
Stability
No data.
Incompatibilities
Incompatible with strong oxidizing agents.
Decomposition
When heated to decomposition it emitx toxis fumes of chloride and sodium oxide.

Fire.
Fire fighting
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use water in flooding quantities as fog. Use alcohol foam, dry chemical or carbon dioxide. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Keep run-off water out of sewers and water sources.
Fire potential
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
Hazards
Contact with metals may evolve flammable hydrogen gas.
Combustion products
Irritating vapors and toxic gases, such as hydrogen chloride, polychlorodibenzodioxins and carbon monoxide, may be formed when involved in fire.

Exposure effects
Rapid breathing, hyperpyrexia, rapid heart rate, and elevated blood pressure can occur with pentachlorophenol intoxication. Headache, dizziness, seizures, anesthesia, coma, and cerebral edema have been reported. Pentachlorophenol has been embryotoxic, fetotoxic, and teratogenic in experimental animals.
   Ingestion
Inflammation of the gastric mucosa is caused by sodium pentachlorophenate. Anorexia occurs with severe exposure. Gi upset may be seen.
   Inhalation
Irritation of the respiratory tract can occur from exposure to fine dust or spray. Bronchitis and tachypnea are common symptoms of intoxication of both animals and humans.
   Skin
Pentachlorophenol is a strong skin irritant. Irritation and dermatitis generally occurs with concentrations greater than 10%.
   Eyes
Strong irritation of the eyes, nose, throat, and mucous membranes is seen. Tearing occurs. Burns and permanent corneal injury may occur. Slight prolonged dialation of the pupils, corneal opacity, and corneal numbness may be seen after exposures to concentrations of a dust or spray.

First aid
 
   Ingestion
Do not induce emesis. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
   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
Rapid decontamination is important, since this material is absorbed through the skin. Primary treatment are measures which promote heat loss, reduce anxiety, and allow for replacement of fluid and electrolytes lost through sweating. Remove contaminated clothing and jewelry. Wash the skin, including hair and nails, vigorously; do repeated soap washings. Discard contaminated clothing.
   Eyes
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility. See treatment of eye exposure in the main body of this document for complete information.
