Precautions when Using Plumbous Nitrate

1. Overview of the dangers of plumbous nitrate

Lead and its compounds impair hematopoiesis, nerves, digestive system and kidney damage. Occupational poisoning is mainly chronic. The main manifestations of the nervous system are neurasthenic syndrome, peripheral neuropathy (more obvious involvement of motor function), and lead poisoning encephalopathy in severe cases. Digestive system manifestations include gum lead, loss of appetite, nausea, abdominal distension, diarrhea or constipation; abdominal cramps are seen in cases of moderate and severe poisoning. Hematopoietic system damage occurs porphyrin metabolism disorders, anemia and so on. Short-term large-scale exposure can cause acute or subacute poisoning, similar to severe chronic lead poisoning. Kidney damage is more common in acute subacute poisoning or severe chronic cases.

2. First aid measures for plumbous nitrate

(1) Skin contact: Take off the clothes contaminated with pb nitrate, and rinse the skin thoroughly with soap and water.

(2) Eye contact: Lift the eyelids and rinse with running water or normal saline. seek medical attention.

(3) Inhalation: quickly leave the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. seek medical attention.

(4) Ingestion: Drink enough warm water to induce vomiting. seek medical attention.

3. Fire-fighting measures for plumbous nitrate

(1) Hazardous properties: inorganic oxidants. In case of easy oxides, it reacts violently immediately, catching fire and exploding. Pb nitrate can form explosive mixtures when mixed with reducing agents, organic substances, flammable substances such as sulfur, phosphorus or metal powders. Decomposed by high heat, producing toxic nitrogen oxides.

(2) Fire fighting methods: Firefighters must wear gas masks and full-body firefighting suits to put out the fire in the upwind direction. Fog water, sandy soil. Never shoot water directly at the molten material, as this can cause a serious flow fire or cause a violent boil.

4. Emergency treatment of plumbous nitrate leakage

(1) Emergency treatment: isolate the leaked contaminated area and restrict access. It is recommended that emergency personnel wear dust masks (full face masks) and protective clothing. Do not come into direct contact with spillage. Do not allow spillage to come into contact with reducing agents, organics, flammables or metal powders.

(2) Small amount of leakage: collect in a dry, clean, covered container with a clean shovel.

(3) Large amount of leakage: collect and recycle or transport to waste disposal site for disposal.

5. Handling and storage of plumbous nitrate

(1) Precautions for operation: closed operation and enhanced ventilation. Pb ii nitrate operators must undergo special training and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical safety goggles, adhesive protective clothing, and neoprene gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Keep away from flammable and combustible materials. Avoid generating dust. Avoid contact with reducing agents. When handling, it should be lightly loaded and unloaded to prevent damage to packaging and containers. Equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. Empty containers may be harmful residues.

(2) Storage precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Package is sealed. It should be stored separately from combustible (combustible) materials, reducing agents, and edible chemicals, and should not be stored together. Storage areas should be provided with suitable materials to contain spills.
