Inhalation Cough. Sore throat. (See Ingestion).
Local exhaust or breathing protection.
Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.
Skin MAY BE ABSORBED! Redness. Pain. (Further see Ingestion).
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes Redness. Pain.

PENTACHLOROPHENOL, SODIUM SALT (Technical Grade) ICSC: 0532
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
WHITE OR TAN FLAKES OR POWDER, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic and corrosive fumes including hydrogen chloride and dioxins. Reacts with strong oxidants, causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin and the respiratory tract. Inhalation of the substance may cause lung oedema (see Notes). The substance may cause effects on the cardiovascular system and central nervous system. Exposure at high levels may result in unconsciousness or death. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis (chloracne). The substance may have effects on the central nervous system, liver and kidneys. Tumours have been detected in experimental animals but may not be relevant to humans (see Notes).
PHYSICAL PROPERTIES
Solubility in water, g/100 ml at 25C: 33
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. Avoid release to the environment in circumstances different to normal use.
NOTES
Humans are generally exposed to technical grade of the substance which usually contain toxic microcontaminants such as polychlorinated dibenzodioxins and dibenzofurans. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered. Do NOT take working clothes home. Also consult ICSC #0069 (Pentachlorophenol).
