chlorine dioxide

chlorine dioxide is an oxidising substance and must be stored separately from flammable and combustible materials, organic substances, and reducing agents. Oxidiser storage areas require dedicated ventilation and must be kept cool and dry.

chlorine dioxide 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.

chlorine dioxide is corrosive to skin, eyes, or metals. Store in acid-resistant or alkali-resistant cabinets as appropriate. Do not store in metal containers. Secondary containment (drip trays) is required. Segregate from incompatible substances such as strong oxidisers.

chlorine dioxide 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.

chlorine dioxide 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 chlorine dioxide should ensure a written hazard communication programme, including current SDS, employee training records, and GHS-compliant labelling on all containers.
