[Chemical Knowledge]：Specification for storage and transportation of crude benzene

The safety of crude benzene storage and transportation specification

1. Introduction

As an important chemical raw material, crude benzene is widely used in coking, petrochemical, pharmaceutical and other industries. However, due to its flammable and toxic properties, there is a greater safety risk in the storage and transportation of crude benzene. In order to ensure the safety of people's lives and property and promote the healthy development of the chemical industry, it is particularly important to formulate the safety storage and transportation specifications of crude benzene.

2. Normative Reference Document

This specification refers to the following documents: GB 13690-2009 "General Rules for Classification and Hazard Publicity of Chemicals", GB 6944-2012 "Classification and Name Number of Dangerous Goods", GB/T 21648-2008 "General Technical Conditions for Transport Packaging of Dangerous Goods", etc.

3. Terms and Definitions

1. Crude benzene: refers to the coal tar as raw material, obtained after distillation containing benzene, toluene, xylene and other components of the mixture.
2. Storage: refers to the storage of crude benzene in warehouses, storage tanks and other places.
3. Transportation: refers to the transportation of crude benzene by road, railway, waterway and other modes of transportation.

4. storage specification

1. Warehouse location: crude benzene warehouse should be built in a well-ventilated place away from fire and heat sources, and keep a safe distance from residential areas and open fire workplaces.
2. tank selection: crude benzene storage tank should be in line with national standards of pressure vessels, with sufficient strength and sealing.
3. Safety facilities: the warehouse shall be equipped with fire fighting equipment, fire doors, fire windows and other safety facilities, and ensure that they are in good condition and effective.
4. Storage management: regular inspections shall be carried out during the storage of crude benzene, and the leakage of liquid and gas shall be dealt with in time. At the same time, safety training should be carried out for warehousing personnel to ensure that they master safe operation procedures.

5. transport specifications

1. transport vehicles: crude benzene transport vehicles should meet the relevant national standards, with dangerous goods transport qualification, and regular maintenance and testing.
2. Driver requirements: the driver should hold the corresponding dangerous goods transport qualification certificate, and received the crude benzene transport safety training.
3. Transportation route: the transportation of crude benzene should choose the route with smooth road and smooth traffic, and avoid passing through sensitive areas such as densely populated areas and important facilities.
4. Emergency measures: corresponding emergency equipment and protective articles, such as fire extinguishers and gas masks, shall be provided during transportation to deal with emergencies.

6. safety protection measures

1. health monitoring: contact with crude benzene workers should be regularly health check, found abnormal timely treatment.
2. Personal protection: Operators should wear gas masks, protective gloves and other personal protective equipment in accordance with national standards.
3. Operating environment: The crude benzene workplace shall be well ventilated, and warning signs shall be set up to prohibit open fire operation.
4. Emergency rescue: The enterprise should formulate emergency plans for crude benzene leakage and fire, and conduct regular drills to improve emergency rescue capabilities.

7. supervision and management

enterprises should establish and improve the storage and transportation management system of crude benzene, clarify the responsibilities of managers at all levels, strengthen daily supervision and inspection, and ensure the effective implementation of various safety measures. At the same time, government regulatory departments should strengthen the supervision of the storage and transportation of crude benzene in enterprises, and deal with violations of laws and regulations in a timely manner.

8. summary

crude benzene as a raw material for chemical production, its safety storage and transportation regulations are of great significance to ensure the safety of people's lives and property and promote the development of the chemical industry. Enterprises should implement various safety measures in strict accordance with the requirements of the regulations, and government regulatory agencies should strengthen supervision and jointly maintain a good safe production environment.
