1. 2-(4-Aminophenyl)ethanol CAS 104-10-9 must be stored in a tightly sealed container under inert gas (nitrogen or argon) in a cool, dry, and well-ventilated environment, protected from light and air as it is air sensitive .
2. Recommended storage conditions include keeping in a cool and dark place below 15°C or at room temperature in a tightly closed container, with the compound stable for extended periods when stored under inert atmosphere .
3. 2-(4-Aminophenyl)ethanol is classified with GHS signal word "Warning" and hazard statements H315 (Causes skin irritation), H319 (Causes serious eye irritation), and H335 (May cause respiratory irritation) .
4. Personnel must wear chemical-resistant nitrile rubber gloves (minimum 0.11 mm thickness, breakthrough time 480 min), safety goggles with side-shields conforming to EN166, and impervious protective clothing when handling this substance, ensuring adequate ventilation and avoiding formation of dust and aerosols .

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable dust respirator (type N95 or P1 filter) when 2-(4-Aminophenyl)ethanol CAS 104-10-9 is released, evacuating non-essential personnel .
2. Collect 2-(4-Aminophenyl)ethanol by sweeping or vacuuming without creating dust using non-sparking tools, and place into suitable closed containers for disposal, avoiding dust generation during cleanup .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; decontaminate surfaces using appropriate methods; prevent the product from entering drains or water courses as discharge into the environment must be avoided (WGK Germany 3 - high water hazard potential) .
4. Dispose of collected material by dissolving or mixing with combustible solvent and burning in a chemical incinerator equipped with an afterburner and scrubber, according to local, state, and federal environmental regulations .

1. 2-(4-Aminophenyl)ethanol CAS 104-10-9 is combustible with NFPA fire rating of 1 (materials that require considerable preheating before ignition), flash point of 127.7±20.4°C, melting point of 107-110°C, and boiling point of 255-287°C; under fire conditions, hazardous decomposition products include toxic fumes of carbon monoxide, carbon dioxide, and nitrogen oxides (NOx) .
2. Use water spray, alcohol-resistant foam, dry chemical powder, or carbon dioxide to extinguish fires involving the product; do NOT use a direct water jet as 2-(4-Aminophenyl)ethanol may scatter burning material .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning 2-(4-Aminophenyl)ethanol due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; move containers from the fire area if safe to do so, cool exposed containers with water spray from a protected location, and contain fire runoff to prevent environmental contamination and pollution .
