Port operations involve the safety of facilities and equipment, ships, goods and personnel in the port area, and belong to the key areas of safety monitoring and management. due to different There are great differences in the aspects of cargo loading and unloading, loading and unloading equipment and facilities, operating techniques and the level of operators in port operation sites. On the basis of considering the safety development level of the industry, the status quo of enterprise safety management and on-site operation experience, according to different types of port operation sites and For the operation projects, the operation safety requirements were formulated respectively, and the mandatory standards for port operation safety requirements were formed into a series of standards, so as to meet the standards The coordination and unification among the various parts is convenient for the use of the document. GB 16994 "Safety Requirements for Port Operations" aims to effectively improve the safety of port operations. level and reduce operational safety risks. GB 16994 is planned to be composed of 7 parts.

1.Oil and gas chemical terminals. The purpose is to clarify the operation safety requirements of the oil and gas chemical wharf and standardize the operation behavior.

2.Petrochemical reservoir area. The purpose is to clarify the operation safety requirements of the port petrochemical storage area and standardize the operation behavior.

3.Dangerous goods containers. The purpose is to clarify the safety requirements for the operation of dangerous goods containers in the port, and to standardize the operation. Behavior.

4.General cargo containers. The purpose is to clarify the safety requirements for the operation of general cargo containers in ports, and to standardize the operation. Behavior.

5.General cargo. The purpose is to clarify the safety requirements for the operation of general cargo in the port and to standardize the operation behavior.

6.Dangerous goods in solid bulk. The purpose is to clarify the safety requirements for the operation of solid and bulk dangerous goods in the port, and to standardize the operation. Behavior.

7.Cement. The purpose is to clarify the safety requirements of port cement operation and standardize the operation behavior. Port operation safety requirements Part

1 Scope

Part 7 of China's mandatory safety requirements for port operations, covering cement. Cement moves through ports in enormous quantity, in bulk by pneumatic conveying and in bags by the shipload, and its hazards are not the obvious ones. Cement dust is caustic - it burns skin and eyes on contact with moisture and causes chronic respiratory damage - so containment and personal protection are the first requirement. The second is the behaviour of the material itself: powdered cement in a silo or a hold aerates and flows like a liquid, so a person walking on the surface sinks and is buried, and the crust that forms over a void collapses without warning. Those are the entry and confined space provisions. Around them sit the pneumatic system's pressure and its dust filtration, the silo venting, and the bagged handling with its manual lifting and stack stability.

This document specifies general requirements for cement handling and storage operations in ports, as well as packing cement operations, bulk cement terminal handling operations and bulk cement operations. Safety technical requirements for the operation of cement silo systems. This document applies to port cement handling and storage operations.
