1. of hydrogen safety storage and transportation specifications
in the field of chemical production raw materials Introduction

hydrogen as an important chemical production raw materials, widely used in petrochemical, fine chemical, new energy and other fields. However, due to the flammable and explosive characteristics of hydrogen, there are certain safety risks in its storage and transportation. In order to ensure production safety, it is essential to establish strict hydrogen storage and transportation regulations.

2. the basic properties of hydrogen

hydrogen is a colorless, tasteless, non-toxic gas, the density is very small, the diffusion coefficient is large, flammable and explosive, and the combustion speed is fast, the combustion calorific value is high. Therefore, special attention should be paid to safety during storage and transportation.

3. hydrogen storage specification

1. Storage facility location: hydrogen storage facilities should be built in a well-ventilated place away from fire, heat and crowded areas. At the same time, hydrogen storage in basements or confined spaces should be avoided.
2. Design of storage facilities: hydrogen storage facilities shall comply with relevant safety standards and have safety measures such as explosion-proof, fire prevention and lightning protection. The storage facilities shall be provided with hydrogen concentration monitoring and alarm device, which shall be linked with ventilation equipment.
3. Storage capacity limitation: According to the hazardous characteristics of hydrogen, the capacity of storage facilities should be limited to reduce safety risks. At the same time, the storage facilities should be inspected and maintained regularly to ensure their safety and reliability.

4. hydrogen transport specifications

1. Transport vehicle requirements: hydrogen transport vehicles should have the appropriate qualifications and certificates, and meet the relevant safety standards. Transport vehicles should be equipped with professional drivers and supercargo to ensure safety during transportation.
2. Transportation packaging requirements: hydrogen should be transported by professional gas cylinders or tankers, and the gas cylinders or tankers should meet relevant safety standards. During transportation, the gas cylinder or tanker should be well sealed to prevent hydrogen leakage.
3. Transportation route planning: hydrogen transportation routes should be as smooth as possible, and avoid driving in crowded areas, near important facilities and other sensitive areas. At the same time, you should know the weather and traffic conditions along the way in advance to ensure safety during transportation.
Emergency treatment
for
5. hydrogen leakage
In the process of hydrogen storage and transportation, once a leakage accident occurs, the following emergency treatment measures should be taken immediately:

1. Cut off the leakage source: firstly, the leakage point should be found as soon as possible, and effective measures should be taken to cut off the leakage source to prevent hydrogen leakage.
2. Ventilation and exhaust: open doors and windows or ventilation equipment, strengthen on-site ventilation, and reduce hydrogen concentration.
3. Evacuate personnel: quickly evacuate personnel near the leakage area, and set up a cordon to prohibit irrelevant personnel from entering the leakage area.
4. Take fire prevention measures: As hydrogen is flammable and explosive, fire prevention measures should be taken, such as using tools that do not produce sparks for operation, and prohibiting open flames.

6. summary

hydrogen is an important raw material for chemical production, and its safety during storage and transportation is very important. In order to ensure production safety, strict hydrogen storage and transportation regulations must be formulated, and effective emergency treatment measures must be taken. By complying with relevant specifications and safe operation requirements, the safety risks during hydrogen storage and transportation can be reduced, and the safety of people's lives and property can be guaranteed.
