Safety aspects of urea and similar substances

Hazardous physicochemical data: Appearance and properties: white crystals or powder with an ammonia odor. Melting point (°C): 132.7 Relative density (water=1): 1.335 Solubility: soluble in water, methanol, ethanol; slightly soluble in ether, chloroform, benzene. Hazardous characteristics: Flammable when exposed to open flames or high temperatures. It reacts with sodium hypochlorite and calcium hypochlorite to produce the explosive nitrogen trichloride. Releases toxic gases upon high-temperature decomposition. Symptoms after contact: This product is classified as slightly toxic. It is irritating to the eyes, skin, and mucous membranes. First aid measures on site: 1. Skin contact: Remove contaminated clothing and rinse with plenty of flowing water. 2. Eye contact: Lift the eyelids and rinse with flowing water or saline. Seek medical attention. 3. Quickly leave the scene and go to a place with fresh air. Keep the airways clear. If there is difficulty breathing, administer oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention. 4. Drink plenty of warm water to induce vomiting. Seek medical attention. Protective measures: Wear protective gloves, protective glasses, and a protective mask. Measures for dealing with leaks and fire suppression methods: 1. Isolate the area contaminated by the leak and restrict access to it. Emergency responders wear dust masks and standard work uniforms. Do not come into direct contact with the leak. 2. For small leaks: carefully sweep them up, place them in a bag, and transfer them to a safe location. 3. Large-scale leakage: Collect and recycle or transport to a waste disposal facility for treatment. 4. Fire extinguishing method: Firefighters must wear full-body fire and poison-resistant suits and extinguish the fire from the upwind side. When extinguishing a fire, move the container away from the fire site to an open area as much as possible. Then, select the appropriate extinguishing agent to put out the fire based on its cause.

I know you were probably writing about urea; thanks! Does anyone else know anything about monoammonium phosphate and potassium chloride?
