The regulations have changed, and a pressure vessel operation certificate is no longer required, but how is a \"quick-opening pressure vessel\" defined?
Thread Content
The latest update from the State Administration for Market Regulation states that, as of June 1, 2019, the new “Catalogue of Personnel Qualifications for Special Equipment Operations” will remove “Inspection and Maintenance of Pressure Pipelines D1” from this list, and replace “Operation of Fixed Pressure Vessels R1” with “Operation of Quick-Opening Pressure Vessels R1”. Generally speaking, this means that operators of ordinary petrochemical facilities will no longer need to obtain any special certifications. Here comes the question: how exactly is the so-called \"quick-opening pressure vessel\" defined? In which tolerance standard or national standard is it defined? If it’s not clearly defined and there’s a misunderstanding, what if one fails to obtain this certificate and is discovered by the quality supervision agency? That would cause serious problems.
In accordance with Article 3.2.16 of the TSG 21-2016 Regulations on Safety Inspection of Fixed Pressure Vessels
Do pressure vessels and pressure pipelines that are not of the quick-opening type no longer require certification?
That's how it is. The intention behind making such a change was that, among all these types of containers, only quick-opening pressure vessels require operation while under pressure by human personnel; this is relatively dangerous, and indeed many accidents have occurred. Common fast-opening pressure vessels today include medical sterilizers, autoclaves used in the construction industry, vulcanization tanks in the rubber industry, and degassing machines used in LCD screen manufacturing, among others.
A special equipment operation permit is no longer required, but a special operations license is still needed; previously, both permits were required
I don’t understand what you mean. As I understand it, the special equipment operation certificate for operators is simply the special equipment operation card; the original requirement was to obtain an R1 certificate, and R1 refers to \"operation of fixed pressure vessels\". Do you need both certificates now? Which two certificates? According to you, do I still need to obtain a special equipment operation certificate in the future?
Could you please explain in detail? I really don’t understand – aren’t a operation permit and a work permit the same thing? Previously, just getting a work permit was considered sufficient; now that it’s been abolished, do we need another permit?
What’s the point of such nonsense? For example, if you work in the field of refrigeration or deal with pressure vessels, you need a refrigeration operation certificate issued by the Work Safety Supervision Bureau as well as an R1 certificate issued by the Quality and Technical Supervision Bureau. If you are involved in chlorination processes that involve pressure vessels, you again need a chlorination operation certificate from the Work Safety Supervision Bureau along with an R1 certificate from the Quality and Technical Supervision Bureau. That’s what is meant in what was said on the 6th floor. As for the industry you work in, the safety supervision agency maintains a corresponding catalog; for hazardous tasks, relevant operation certificates are required. Yesterday, the Urban Market Supervision Bureau inspected our company.
Now you’ve explained it clearly\ud83d\udc4d
