How far should the DIS system be from major hazard sources?
Thread Content
When the teacher checked, he said that our DIS system monitoring room was not located outside the production area, which did not meet the requirements. What does the specification require?
Torment from the soul. . What is a DIS system?
HGT 20508-2014 Control Room Design Code, 3.2 General Layout Location, 3.2.1 1 The control room should be located within the plant or complex, and outside any explosive hazard areas； 2 The central control room should be located in the production management area.
Don’t ask; if you do, it means you’re not qualified to be a teacher; P. . The teacher said that DIS is just DIS
Which teacher. . Piiii! Have him check the specifications; the control room is divided into a central control room and a field control room. The field control room must calculate the explosion risk based on the hazard level of the plant’s processes, in order to determine the required shock resistance. Then, the control room is classified; generally, the field control room and the cabinet room are designed to be shock-resistant (not explosion-proof), with a requirement of at least 35 meters for Class A installations and 30 meters for Class B installations. The central control room is a monitoring room that combines several devices; it can be separated from the on-site cabinets and is generally required to be located outside the production facilities. As for the legal documents issued in your area, they also need to be enforced. The teacher said it verbally; ask the teacher to show the standard.
Dis should refer to distributed discrete control system, commonly known as DCS
The requirements set out in the Three-Year Action Plan for Special Rectification of Work Safety across the Country

SH/T3006 4.2.1 The location of the control room shall comply with the provisions regarding control layout in Section 5.2 of GB 50160-2008. Take a close look; it’s very detailed. 4.2.2 a The control room of the combined unit should be located within the unit itself, and outside any area prone to explosions ； The control room of device b should be located within the device itself, and outside any area prone to explosions ；
