(1) Physical and chemical properties. Appearance and properties:colourless transparent rhombohedral or tripartite crystal system particles or white powder;Melting point:334°C;Relative density(water=1):2.11;Solubility:Soluble in water, insoluble in anhydrous ethanol, ether, etc.This article comes from: https://fireworkslit.com/Fireworkslit-https://fireworkslit.com/fireworks-commonly-used-materials-3-the-properties-of-potassium-nitrate/

(2)Health Hazard. Inhalation of the dust is irritating to the respiratory tract. High concentration of inhalation can cause pulmonary oedema. Large amount of exposure can cause methemoglobinemia, affecting the oxygen-carrying capacity of the blood, headache, dizziness, cyanosis, nausea, vomiting and so on. In severe cases, it may cause respiratory disorders, collapse, or even death. Oral administration causes severe abdominal pain, vomiting, bloody stools, shock, general convulsions, coma, and even death. Strongly irritating to skin and eyes, even causing burns. Repeated skin contact causes dry, cracked skin and rash.This article comes from: https://fireworkslit.com/Fireworkslit-https://fireworkslit.com/fireworks-commonly-used-materials-3-the-properties-of-potassium-nitrate/

(3) Hazardous properties. Strong oxidising agent. When meeting combustible materials on fire, it can fuel the fire. With organic matter, reducing agent, flammable material (such as sulfur, phosphorus, etc.) contact or mixed with the risk of causing combustion and explosion. When burned and decomposed, toxic nitrogen oxides are released. When decomposed by heat, toxic nitrogen oxides will be released.This article comes from: https://fireworkslit.com/Fireworkslit-https://fireworkslit.com/fireworks-commonly-used-materials-3-the-properties-of-potassium-nitrate/

(4) Emergency treatment for leakage. Isolate the leaking contaminated area and restrict access. It is recommended that emergency personnel wear dust masks (full face masks) and anti-virus clothing. Do not contact the leak directly. Do not bring the leak into contact with organic matter, reducing agents, flammable materials, etc. Small amount of leakage: Flush with a large amount of water, dilute the wash water and put it into the wastewater system. A large number of leaks: cover with plastic sheeting, canvas, etc., collected and recycled or transported to the waste disposal site.This article comes from: https://fireworkslit.com/Fireworkslit-https://fireworkslit.com/fireworks-commonly-used-materials-3-the-properties-of-potassium-nitrate/

(5) Fire extinguishing methods. Firefighters shall wear gas masks and full-body firefighting suits. Extinguish the fire with mist water and sand. Do not direct the water stream to the molten material as this may cause a serious stream fire or cause violent boiling and splashing .This article comes from: https://fireworkslit.com/Fireworkslit-https://fireworkslit.com/fireworks-commonly-used-materials-3-the-properties-of-potassium-nitrate/
