EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST!

Inhalation Burning sensation. Cough.
Ventilation (not if powder). Avoid inhalation of fine dust and mist.
Fresh air, rest.
Skin Redness.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes Redness. Pain.
Safety goggles or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion Burning sensation. Cough. Nausea.
Do not eat, drink, or smoke during work. Wash hands before eating.
Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Do NOT wash away into sewer. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Personal protection: P2 filter respirator for harmful particles. Do NOT let this chemical enter the environment.

PICLORAM ICSC: 1246
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALS OR WHITE POWDER, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance decomposes on heating producing nitrogen oxides (see ICSC 0067, ICSC 0930) and hydrogen chloride (see ICSC 0163). Reacts with strong bases. Attacks mild steel.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 10 mg/m as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and by ingestion.

INHALATION RISK:
Evaporation at 20C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes, the skin and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the liver.
PHYSICAL PROPERTIES
Decomposes below melting point at 218-219C
Solubility in water: poor
Octanol/water partition coefficient as log Pow: 1.9
ENVIRONMENTAL DATA
The substance is toxic to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to soil organisms, aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. through inappropriate disposal.
NOTES
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home. Tordon, Amdon, ATCLP, Borolin, K-PIN, Chloramp, Grazon are trade names.
Card has been partly updated in April 2005. See sections Occupational Exposure Limits, Physical properties.
