Practical safety notes

Flammable. Keep away from open flames, hot surfaces and sparks. Ground containers when transferring.
Oxidizing. Keep away from combustibles, organics, reducers and fuels.
Compressed gas. Secure cylinders upright, protect valves, store in ventilated areas.
Corrosive. Wear chemical goggles, faceshield and chemical-resistant gloves. Have an eyewash within reach.
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.

FAQ

Is Chloroethane flammable?+

Yes. Chloroethane (CAS 75-00-3) 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 Chloroethane?+

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 Chloroethane be stored?+

Store Chloroethane (CAS 75-00-3) 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 Chloroethane dangerous for the environment?+

No specific environmental pictogram (GHS09) is listed in our records for Chloroethane, but any chemical waste should be handled through your site's hazardous-waste procedure, not poured down the drain.

Where can I find the official Safety Data Sheet for Chloroethane?+

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.
