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

n-heptane is a common chemical production raw materials, widely used in petroleum processing, rubber, coatings and other fields. However, due to its flammable and toxic characteristics, n-heptane has certain safety risks during storage and transportation. In order to ensure the safety of people's lives and property, it is very important to formulate the safety storage and transportation specifications of n-heptane.

2. the physical and chemical properties of n-heptane

n-heptane is a colorless and transparent liquid with a special odor. Its molecular formula is C7H16 and its molecular weight is 100.21. Heptane is insoluble in water, but is miscible with organic solvents such as alcohols and ethers. It has a low flash point, is flammable, and produces a bright flame when burning. In addition, n-heptane is also toxic, prolonged exposure or inhalation can lead to human poisoning.

3. n-heptane safety storage specification

1. storage place should be selected in a well-ventilated, away from the fire source, and set up obvious safety warning signs.
2. The storage container shall be a special storage tank with good sealing performance to avoid n-heptane leakage.
3. The storage site shall be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment to ensure safety.
4. Check and maintain the storage container regularly to ensure that it is intact.
5. Storage personnel should be professionally trained to understand the nature of n-heptane and safe operating procedures.

4. n-heptane safety transport specification

1. transport vehicles should meet the relevant standards, with effective fire, explosion, leakage and other safety facilities.
2. During transportation, stable driving shall be maintained, and operations such as sudden braking and sharp turning shall be avoided to prevent leakage of n-heptane.
3. transport personnel should be professionally trained to understand the nature of n-heptane and safe operation procedures.
4. Relevant laws and regulations shall be observed during transportation to ensure transportation safety.

5. n-heptane leakage emergency treatment measures

1. found n-heptane leakage, should immediately stop the operation, close the source of leakage, to prevent leakage expansion.
2. Cover and absorb the leakage with sand, dry lime and other adsorption materials to avoid flowing into sewers or drains.
3. Ventilate the leakage area to reduce the concentration of n-heptane.
4. In the event of a fire, immediately use foam, dry powder and other fire extinguishing equipment to extinguish the fire, and call the police for help.

6. of n-heptane safety protection measures

1. contact with n-heptane operators should wear professional protective gloves, masks and other personal protective equipment, to avoid direct contact with n-heptane.
2. The workplace should be equipped with ventilation facilities to maintain air circulation and reduce the concentration of n-heptane.
3. Regular occupational health examination shall be carried out for the operators, and any abnormal situation shall be handled in time.

7. conclusion

n-heptane as a common chemical production raw material, there are certain safety risks in the process of storage and transportation. In order to ensure the safety of people's lives and property, strict safety storage and transportation regulations must be formulated, and effective protective measures must be taken. By complying with relevant specifications and measures, the risk of safety accidents such as n-heptane leakage and fire can be reduced, and production safety and personnel health can be guaranteed.
