- Compressed gas. Secure cylinders upright, protect valves, store in ventilated areas.
- 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 sulfuryl fluoride flammable?+
sulfuryl fluoride (CAS 2699-79-8) does not carry the GHS02 flame pictogram in our records. Always confirm with the manufacturer's SDS section 9 (flash point) before assuming a product is non-flammable.
What PPE should I wear when handling sulfuryl fluoride?+
Safety glasses with side shields and nitrile gloves are the baseline. Work inside a fume hood or use a suitable respirator. Check SDS section 8 for material-specific breakthrough times.
How should sulfuryl fluoride be stored?+
Store sulfuryl fluoride (CAS 2699-79-8) in tightly closed original containers, in a cool, dry, well-ventilated area away from incompatible materials.
Is sulfuryl fluoride dangerous for the environment?+
Yes. sulfuryl fluoride 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 sulfuryl fluoride?+
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.
