Do all chemical processing units need to be equipped with SIS after 2020?
Thread Content
Article 13 of Document No. An Jian Zong Guan San [2014] 116 stipulates that \"as of January 1, 2018, all newly constructed chemical processing units and hazardous chemical storage facilities that fall under the category of ‘two key areas and one major hazard’ must be designed with safety instrument systems that meet the required standards.\" For the safety instrument systems of other newly built chemical processing units and hazardous chemical storage facilities, starting from January 1, 2020, it is necessary to comply with the requirements of functional safety standards and design safety instrument systems that meet those requirements. ”Has it been the case since 2020 that all chemical processing units, regardless of whether they are related to the \"two key areas and one major issue\", need to be equipped with SIS?
I’m afraid there won’t be a one-size-fits-all approach; it depends on the specific circumstances in each area.
Chemical processing units and hazardous chemical storage facilities that fall under the category of “two key aspects and one major issue” must be equipped with safety instrumented systems; they should comply with the requirements of functional safety standards, and their safety instrumented systems must be designed in accordance with those requirements. Based on a comprehensive conduct of process hazard analysis (such as Hazard and Operability Analysis), safety instrument functions and the associated risk reduction requirements should be determined through risk analysis, and it is necessary to assess as soon as possible whether the existing safety instrument functions meet these risk reduction requirements.
I agree with what was said on the 3rd floor; **the regulations regarding work safety are being continuously improved, and they will only become stricter in the future
What I would like to ask is: after 2020, do new projects that do not fall under the category of “two key areas and one major project” still need to be included in the SIS?
SIS has been added on-site right now; it has already been implemented.
We have encountered this issue before; experts understand it from the documents as follows: depending on the type of your equipment, since we use a distillation process, installing the SIS system throughout might prevent the operation of the equipment. There is an explanation in the documents from Shandong Province, stating that the system should be installed as appropriate – it’s not necessary to install it everywhere, as doing so could prevent the equipment from functioning. The documents specify that such systems are only required in cases involving key points as well as primary and secondary major hazard sources
**The text: items of key importance and those at level one and two need to be installed
That is a requirement for two key points and one major aspect. If it does not involve two key aspects and one major issue, a safety assessment will be conducted to determine whether it is necessary to proceed.
1. For hazardous chemicals that are only subject to strict supervision, without any hazardous processes and not constituting major hazard sources, is it necessary to install a SIS? 2. Do all hazardous chemicals and processes that are subject to strict regulation and also constitute major hazard sources need to be integrated into a SIS?
