Fire Hazards
Excerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:
Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.
Health HazardsExcerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:
Hazards Summary
Causes somnolence and gastrointestinal changes in oral lethal-dose studies of rats; Causes changes in renal tubules and weight loss in 13-week oral studies of rats; [RTECS] Causes burns; Inhalation of aerosol may cause pulmonary edema; [ICSC] A skin and strong eye irritant; [Alfa Aesar MSDS] See Potassium phosphate, tribasic, Potassium phosphate, dibasic, Potassium metaphosphate, and Pentapotassium triphosphate.
Reactive GroupSalts, Basic
EPA Safer ChemicalChemical: Tetrapotassium pyrophosphate
Reactivity Profile
Salts, basic, such as POTASSIUM TETRAPYRO PHOSPHATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.
Chemical DangersThe solution in water is a medium strong base. Reacts with strong acids.
Air and Water ReactionsSoluble in water.
Hazard Classes and CategoriesEye Irrit. 2 (96.5%)
安全と保護具
Fire Fighting
Excerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:
In case of fire in the surroundings, use appropriate extinguishing media.
First Aid Measures
Fresh air, rest. Half-upright position. Refer for medical attention.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth. Do NOT induce vomiting. Refer for medical attention .
First AidExcerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:
Safe StorageSeparated from strong acids. Dry.
Nonfire Spill ResponseExcerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:
Spillage DisposalPersonal protection: chemical protection suit including self-contained breathing apparatus. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water.
Isolation and EvacuationExcerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:
Eye PreventionWear face shield or eye protection in combination with breathing protection.
Inhalation RiskEvaporation at 20 °C is negligible; a harmful concentration of airborne particles can, however, be reached quickly , especially if powdered.
Skin PreventionProtective gloves. Protective clothing.
Exposure PreventionPREVENT DISPERSION OF DUST! AVOID ALL CONTACT!
Ingestion PreventionDo not eat, drink, or smoke during work.
毒性情報
