Instrument Operation Certificate

According to **relevant laws and regulations, operating explosion-proof equipment requires a certification for working with explosion-proof devices. However, for ordinary instrument operators, whether it is necessary to hold an explosion-proof operation certificate depends on the specific circumstances. If it is indeed necessary to come into contact with and operate explosion-proof equipment at work, then having an explosion-proof operation certificate is essential. However, if one is only performing routine instrument operations without direct contact with explosion-proof equipment, it may not be necessary to hold an explosion-proof operation certificate. Therefore, it is necessary to determine whether an explosion-proof operation certificate is required based on the specific working conditions. .

Factories that employ hazardous processes must have automated instrumentation operation permits

It is necessary to clarify first whether the term “instrument operator” here refers to a maintenance technician for instruments or a DCS operator; if it is the former, one must hold a certificate for working with automated control instruments as well as a certificate for low-voltage electrical work； In the latter case, only an automated control instrument operation certificate is required (I personally think it’s not necessary for DCS operators, as the content of the exam focuses on the inspection and maintenance of instruments and control systems; however, certain chemical industry associations consider it a serious hazard if control room staff do not hold this certificate, so one has to take the exam). If there are hazardous processes involved, then a certificate specific to operating those hazardous processes is also needed. Regarding the necessity of holding an explosion-proof (electrical) operation certificate: On August 26, 2020, the Ministry of Emergency Management issued a letter seeking opinions on the \"Catalogue of Special Operations (Draft for Comment)\". The revised catalogue removes the requirement for an explosion-proof electrical operation certificate, incorporating related requirements for explosion-proof electrical work into the assessment criteria for low-voltage and high-voltage electricians. Until this revised catalogue is officially published, instrument technicians still need to obtain an explosion-proof (electrical) operation certificate, or they must work alongside electricians who hold such certificates when carrying out relevant inspection and maintenance tasks ； DCS operators do not need to obtain an explosion-proof (electrical) operation certificate. On January 29, 2021, a query was made to the Ministry of Emergency Management (see figure below), but to date no new list of special operations has been released. The \"Catalogue of Special Operations (Draft for Comment)\\" has not yet been officially implemented; therefore, it is still necessary to follow the scope of special operations stipulated in the current \"Regulations on the Safety Technology Training and Assessment Management for Personnel Engaged in Special Operations\" (formerly Order No. 30 issued by the **State Administration for Work Safety\").
