Tripotassium phosphanide requires careful handling using appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Due to its reactive nature, avoid contact with water and moisture. Use non-sparking tools and ensure all equipment is properly grounded. Emergency washing facilities should be readily accessible during handling operations.

Tripotassium phosphanide must be stored in tightly sealed, moisture-proof containers in a cool, dry, well-ventilated area away from incompatible materials. Keep the compound away from water, acids, and oxidizing agents to prevent dangerous reactions. Storage areas should be equipped with appropriate fire suppression systems and maintained at stable temperatures. Regular inspection of containers for signs of degradation or moisture ingress is essential for safe storage.

Immediate action is required for any contact with tripotassium phosphanide. For skin contact, remove contaminated clothing and wash the affected area thoroughly with plenty of water for at least 15 minutes. In case of eye contact, flush immediately with clean water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air and provide oxygen if breathing is difficult. Seek immediate medical attention for all exposure incidents.

Tripotassium phosphanide disposal must comply with local and national hazardous waste regulations. The compound should never be disposed of in regular waste streams or sewage systems due to its reactive nature. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Small quantities may require neutralization under controlled conditions before disposal. Always consult local environmental authorities for specific disposal requirements and approved treatment facilities.

Tripotassium phosphanide is classified under ADR Class 4.3 (substances which, in contact with water, emit flammable gases), Packing Group I, indicating high danger level. Transportation requires specialized packaging meeting UN specifications and proper hazard labeling. Only certified carriers with appropriate permits can transport this material. Documentation must include proper shipping names, hazard classes, and emergency response information. Vehicles must be equipped with appropriate emergency equipment and placarding.
