Open comparator with acroleinPractical safety notes
- Flammable. Keep away from open flames, hot surfaces and sparks. Ground containers when transferring.
- Corrosive. Wear chemical goggles, faceshield and chemical-resistant gloves. Have an eyewash within reach.
- Acute toxicity. Work under a fume hood, restrict access, keep a specific antidote plan available.
- Irritant / harmful. Ventilate the workspace and avoid skin contact.
- Serious health hazard (carcinogen, mutagen, reprotoxic, respiratory sensitizer). Substitute if possible; otherwise closed systems and medical surveillance.
- Environmental hazard. Do not release to sewers or waterways; collect for hazardous waste disposal.

FAQ
Is acrolein flammable?+
Yes. acrolein (CAS 107-02-8) 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 acrolein?+
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 acrolein be stored?+
Store acrolein (CAS 107-02-8) 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 acrolein dangerous for the environment?+
Yes. acrolein 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 acrolein?+
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.
