TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Foam. Dry powder. Carbon dioxide.
EXPLOSION Above 62C explosive vapour/air mixtures may be formed.
Above 62C use a closed system, ventilation.

EXPOSURE See NOTES.
PREVENT DISPERSION OF DUST!

 •INHALATION
Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
 •SKIN
Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
 •EYES
Safety goggles or eye protection in combination with breathing protection if powder.
Rinse with plenty of water (remove contact lenses if easily possible).
 •INGESTION
Do not eat, drink, or smoke during work.
Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment.
Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing. Separated from strong oxidants, food and feedstuffs .
Do not transport with food and feedstuffs.
UN Hazard Class: 6.1
UN Packing Group: III
Toxic to aquatic life

ENVIRONMENTAL
DATA
Environmental Hazard placard The substance is toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. 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.
N O T E S
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. No data are available on this isomer but a mixture of trichlorophenols may cause irritation of the skin, eyes and respiratory tract. These substances may cause acute metabolic effects resulting in damage in several organs notably CNS. Some technical products may contain highly toxic impurities including polychlorinated dibenzo-p-dioxins and -furans. Depending on the degree of exposure, periodic medical examination is suggested.
