FAQ
Is Isopropyl alcohol flammable?+
Yes. Isopropyl alcohol (CAS 67-63-0) carries the GHS02 flame pictogram. Keep it away from ignition sources, use non-sparking tools, and ground metal containers when transferring liquid.
What PPE should I wear when handling Isopropyl alcohol?+
Chemical-splash goggles and a faceshield, chemical-resistant gloves (nitrile or butyl) and an apron are the minimum. Work inside a fume hood or use a suitable respirator. Check SDS section 8 for material-specific breakthrough times.
How should Isopropyl alcohol be stored?+
Store Isopropyl alcohol (CAS 67-63-0) in tightly closed original containers, in a cool, dry, well-ventilated area away from incompatible materials. Use a flammable-liquid cabinet and keep away from oxidizers and heat. Segregate acids from bases and keep away from metals that can be attacked.
Is Isopropyl alcohol dangerous for the environment?+
Yes. Isopropyl alcohol carries the GHS09 environment pictogram. Do not release to drains, soil or waterways; collect residues for hazardous-waste disposal in line with local regulations.
Where can I find the official Safety Data Sheet for Isopropyl alcohol?+
Official, up-to-date SDS documents are published by each manufacturer (Sigma-Aldrich, Merck, Thermo Fisher, VWR, Carl Roth, etc.) and by regulators such as ECHA and NIOSH. This page is an educational summary and does not replace the manufacturer's SDS.
