4-(cyanomethyl)-4-methylmorpholin-4-ium hydrogen sulfate 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.

4-(cyanomethyl)-4-methylmorpholin-4-ium hydrogen sulfate may cause irritation to skin, eyes, or respiratory tract, or has low-level systemic toxicity. Adequate ventilation must be provided in work areas. Personal protective equipment (gloves, eye protection) is recommended during handling.

This substance carries the signal word DANGER, indicating the more severe hazard categories under GHS/CLP. Facilities handling 4-(cyanomethyl)-4-methylmorpholin-4-ium hydrogen sulfate should ensure a written hazard communication programme, including current SDS, employee training records, and GHS-compliant labelling on all containers.
