[Chemical Knowledge]：Specification for storage and transport of potassium bromide

Chemical production of raw materials in the field of potassium bromide safety storage and transport specifications

1. Introduction

of potassium bromide is an important chemical raw materials, widely used in medicine, pesticides, photography, analytical chemistry and other fields. Due to its special physical and chemical properties, potassium bromide needs to strictly abide by certain safety regulations during storage and transportation to ensure the safety of personnel and the environment. This article will detail the safety storage and transportation specifications of potassium bromide.

2. the nature of potassium bromide

potassium bromide is a colorless crystal or white powder, with strong hygroscopicity. It is easy to dissolve in water, and its aqueous solution is neutral or slightly alkaline. Potassium bromide is sensitive to light, easy to decompose at high temperature, and release hydrogen bromide gas. In addition, potassium bromide is also corrosive and has a certain corrosive effect on metals.

3. safety storage specifications for potassium bromide

1. Storage environment: Potassium bromide should be stored in a dry, cool, well-ventilated indoor environment, avoiding direct sunlight and high temperature.
2. Storage container: Use a container with good sealing performance for storage to prevent moisture absorption and contamination.
3. Storage isolation: Potassium bromide should be stored in isolation with oxidants, acids, alkalis and other substances to avoid chemical reactions with them.
4. Storage identification: A prominent label on the storage container indicating the name of the substance, the nature of the hazard and precautions.

4. safety of potassium bromide transport specification

1. packaging requirements: potassium bromide should be lined with plastic bags of iron drum or plastic drum packaging, to ensure good sealing performance. Packaging containers should meet the relevant standards and have sufficient strength and compression resistance.
2. Transport vehicles: use special dangerous goods transport vehicles for transportation to ensure that the vehicles are in good condition and have the functions of fire prevention, explosion prevention and leakage prevention.
3. Transportation personnel: transportation personnel should be professionally trained and familiar with the nature of potassium bromide and transportation safety knowledge.
4. Transportation route: Choose a reasonable transportation route to avoid passing through sensitive areas such as densely populated areas and water source protection areas.
5. Transport identification: Obvious dangerous goods identification shall be set on the transport vehicle, indicating the name of the substance, the nature of the hazard and precautions.

5. potassium bromide leakage treatment measures

1. Quickly evacuate the personnel from the leakage pollution area to the safety area, isolate and strictly restrict access. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and protective clothing. Do not touch the leak directly. Cut off the leak source as much as possible.
2. Small amount of leakage: adsorption or absorption with sand or other non-combustible materials. Can also be washed with a lot of water, wash water diluted into the waste water system.
3. Large amount of leakage: construct embankment or dig pit for containment. Transfer to tank truck or special collector by pump, recycle or transport to waste disposal site.

6. potassium bromide fire measures

1. Hazardous characteristics: by high thermal decomposition of toxic bromide gas. Can react with acids. Can react strongly with oxidants. It can burn and explode in case of open fire. When exposed to heat decomposition of toxic bromide gas, combustion (decomposition) products: hydrogen bromide, potassium oxide. Fire extinguishing method: firefighters must wear full-body fire protection clothing and put out the fire in the upwind direction. When extinguishing fire, move the container from the fire to an open place as much as possible. Then choose the appropriate fire extinguishing agent according to the cause of the fire.
2. Emergency treatment: isolate the leakage pollution area and restrict access. It is recommended that emergency personnel wear dust mask (full face mask) and protective clothing. Do not touch the leak directly. Small amount of leakage: avoid dust, sweep carefully and collect in a closed container. Large leakage: collection and recycling or transportation to waste disposal site. Eye contact: Lift the eyelid and flush with flowing water or normal saline. Seek medical attention. Inhalation: quickly leave the site to fresh air. Keep the airway unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention. Intake: Drink plenty of warm water to induce vomiting. Seek medical attention. Respiratory system protection: when the concentration in the air exceeds the standard, you must wear a self-priming filter dust mask. Emergency rescue or evacuation, should wear air respirator. Eye protection: wear chemical safety goggles. Body protection: wear anti-poison penetration overalls. Hand protection: wear rubber gloves. Other protection: smoking, eating and drinking are prohibited at the work site. After work, shower and change clothes. Maintain good hygiene habits. Pre-employment and regular medical examinations are carried out.

7. summary

potassium bromide as an important chemical raw material, it is necessary to strictly abide by safety regulations during storage and transportation to ensure the safety of personnel and the environment. By understanding the nature of potassium bromide, storage and transportation specifications, as well as leakage treatment and fire protection measures, we can effectively prevent and respond to potassium bromide-related safety accidents.
