Phloroglucinol white or light yellow crystalline or crystalline powder. It is mainly used for the identification of chemical elements, the concentration of hydrochloric acid in tissues, and the detection of multi-plant vascular bundles.


The precautions for using pyrogallol in the experiment are as follows:


Risk overview


Health hazards: acute poisoning: can cause vomiting, low body temperature, weakness, ataxia, purpura, coma, suffocation, and even death. Long-term exposure can cause anemia, jaundice, etc.; it is sensitizing to the skin and causes eczema.

Explosion hazard: This product is flammable, toxic and sensitizing.


first-aid


Skin contact: Immediately remove contaminated clothing and rinse with plenty of running water for at least 15 minutes. Seek medical attention.

Eye contact: Immediately lift eyelids and rinse thoroughly with plenty of running water or saline for at least 15 minutes. Seek medical attention.

Inhalation: Remove quickly from the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention.

Ingestion: Drink plenty of warm water and induce vomiting. Seek medical attention.


Fire-fighting measures


Hazardous characteristics: In case of fire, high heat and flammable. The toxic gas is liberated by high heat. A chemical reaction can occur upon contact with a strong oxidizing agent.

Hazardous combustion products: carbon monoxide, carbon dioxide.

Extinguishing method: use mist water, anti-solvent foam, dry powder, carbon dioxide, sand to extinguish the fire.


Leakage emergency treatment


Emergency treatment: Isolation of contaminated areas and restrictions on access. Cut off the fire source. It is recommended that emergency personnel wear a dust mask (full face mask) and wear a protective suit.

Small amount of leakage: Avoid dust, carefully sweep it, and place it in a bag and transfer it to a safe place. It can also be rinsed with a large amount of water, diluted in water and placed in the wastewater system.

A large amount of leakage: covered with plastic cloth and canvas. It is then collected for recycling or transported to a waste disposal site for disposal.


Handling and storage


Handling precautions: Closed operation to provide adequate local exhaust. Take isolation as much as possible. Operators must be specially trained to strictly follow the operating procedures. Operators are advised to wear self-priming filter dust masks, safety glasses, anti-poisoning overalls, and rubber gloves. Keep away from fire, heat, and smoking in the workplace. Use explosion-proof ventilation systems and equipment. Avoid dust. Avoid contact with oxidants and acids. Lightly load and unload during handling 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.


Storage Precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat. The package is sealed and must not be in contact with air. It should be stored separately from oxidants, acids and food chemicals, and should not be mixed. Equipped with the appropriate variety and quantity of fire equipment. The storage area should be provided with suitable materials to contain spills.
