| Reactivity Profile | 2-AMINO-4-CHLOROPHENOL may react with strong oxidizing agents. (NTP, 1992) |
| Chemical Dangers | Decomposes on heating and on burning. This produces toxic and corrosive fumes including hydrogen chloride and nitrogen oxides. Reacts with oxidants. |
| Packaging and Labelling | Do not transport with food and feedstuffs. |
| Brandbekämpfung | Excerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:Use water spray, foam, powder, carbon dioxide. |
| Erste-Hilfe-Maßnahmen | 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 . |
| Freisetungsmaßnahmen | · 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. |
| Erste Hilfe | 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: |
| Sichere Lagerung | Separated from oxidants and food and feedstuffs. |
| Expositionsschutz und Persönliche Schutzausrüstung | · Wear positive pressure self-contained breathing apparatus (SCBA). |
| Freisetung ohne Brand | Excerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]: |
| Verschüttetes entsorgen | 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. |
| Isolation and Evacuation | Excerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:Immediate precautionary measure |
| Eye Prevention | Wear safety goggles. |
| Fire Prevention | NO open flames. |
| Inhalation Risk | A nuisance-causing concentration of airborne particles can be reached quickly when dispersed, especially if powdered. |
| Unerwünschte Wirkungen | Methemoglobinemia - The presence of increased methemoglobin in the bloodthe compound is classified as secondary toxic effect |
| Expositionspfade | The substance can be absorbed into the body by inhalation and by ingestion. |
| Toxizitätsübersicht | 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.Safe for use in cosmetics, with qualifications |
