Potassium nitrate (data page)
Potassium nitrate is an oxidizer so storing it near fire hazards or reducing agents should be avoided to minimise risk in case of a fire.
Additional recommended knowledge
Synonyms : Saltpeter; Niter; Nitric acid potassium salt; Salt Peter
Health Rating : 1 - Minimal
Inhalation : Causes irritation to the respiratory tract. Symptoms may include coughing, shortness of breath.
First Aid Measures
Inhalation : Move to fresh air.
Fire Fighting Measures
Fire : Not combustible, but substance is a strong oxidizer and its heat of reaction with reducing agents or combustibles may cause ignition.
Accidental Release Measures
Remove all sources of ignition. Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Spills: Clean up spills in a manner that does not disperse dust into the air. Use non-sparking tools and equipment. Reduce airborne dust and prevent scattering by moistening with water. Pick up spill for recovery or disposal and place in a closed container.
Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage and moisture. Isolate from any source of heat or ignition. Avoid storage on wood floors. Separate from incompatibles, combustibles, organic or other readily oxidizable materials.
Exposure Controls/Personal Protection
Ventilation System : A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.
Physical and Chemical Properties
Appearance : White crystals.
Stability and Reactivity
Stability : Stable under ordinary conditions of use and storage.
Hazardous Decomposition Products : Oxides of nitrogen and toxic metal fumes may form when heated to decomposition.
Whatever cannot be saved for recovery or recycling should be handled as hazardous waste and sent to a RCRA approved waste facility. Processing, use or contamination of this product may change the waste management options. State and local disposal regulations may differ from federal disposal regulations. Dispose of container and unused contents in accordance with federal, state and local requirements.
