sulphuryl difluoride

sulphuryl difluoride is stored and transported as a compressed gas. Cylinders must be secured upright, protected from physical damage, and stored away from heat sources. Ensure adequate ventilation to prevent accumulation of gas in confined spaces.

sulphuryl difluoride has acute toxicity (oral, dermal, or inhalation) classified as Category 1–3. Access to this substance must be restricted to trained personnel. Store in a locked, well-ventilated area. Exposure monitoring and medical surveillance may be required under OSHA 29 CFR 1910.1000 or equivalent regulations.

sulphuryl difluoride is classified as a specific target organ toxicant (STOT). Exposure must be minimised using engineering controls (local exhaust ventilation, closed systems). Biological and medical monitoring may be required. Refer to the full Safety Data Sheet (SDS) Section 8 for occupational exposure limits.

sulphuryl difluoride is hazardous to the aquatic environment. Do not allow this substance to enter drains, waterways, or soil. Spills must be contained immediately using appropriate absorbent material. Disposal must comply with local environmental regulations — consult the SDS Section 13 for guidance on waste treatment.

This substance carries the signal word DANGER, indicating the more severe hazard categories under GHS/CLP. Facilities handling sulphuryl difluoride should ensure a written hazard communication programme, including current SDS, employee training records, and GHS-compliant labelling on all containers.
