Excerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:

· Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.

Combustible. Gives off irritating or toxic fumes (or gases) in a fire.

Excerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:

· Highly toxic, may be fatal if inhaled, ingested or absorbed through skin.

Excerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:

Use water spray, foam, powder, carbon dioxide.

Fresh air, rest. Seek medical attention if you feel unwell.

Wear protective gloves when administering first aid. Remove contaminated clothes. Rinse and then wash skin with water and soap.

Rinse with plenty of water for several minutes (remove contact lenses if easily possible).

Rinse mouth. Refer for medical attention .

· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.

· Do not touch damaged containers or spilled material unless wearing appropriate protective clothing.

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

General First Aid:

Personal protection: particulate filter respirator adapted to the airborne concentration of the substance, protective clothing and protective gloves. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

Immediate precautionary measure

The CIR Expert Panel concludes that the available data support the safety of 6-Amino-m-Cresol, 4-Amino-m-Cresol, 5-Amino-4-Chloro-o-Cresol and 5-Amino-6-Chloro-o-Cresol as used in oxidative and nonoxidative (semipermanent) for dyes. The available data also support the safety of 6-Amino-o-Cresol and 4-Chloro-2-Aminophenol for use in oxidative hair dyes, but are insufficient to support the safety of 6-Amino-o-Cresol and 4-Chloro-2-Aminophenol and nonoxidative (semipermanent) hair dyes.
