I would like to ask: do the gas alarms designed by design institutes for chemical plants need to have all three necessary certifications?
Thread Content
RT, I would like to know whether, when design institutes establish standards for gas alarms in chemical plants, they require that such alarms have all three necessary certifications. In many chemical plants of moderate size, the alarms in use possess both explosion-proof features and certification for accuracy measurement. Are there few fire safety certifications (type approval)? Because meters with all three certificates are slightly more expensive
The design specifications for alarms only specify explosion-proof requirements; they make no mention of metering or fire protection. However, reputable and **certified** alarm manufacturers can certainly provide those specifications.
It seems that starting from last year, 2015, combustible gas detection products have also been included in fire safety certification. CCCF. You can look it up online for specific details.
Ask the manufacturer! He said it can be used; you can just use theirs! That way, there will be no problem
What was said upstairs is correct; first of all, the manufacturer claims that it can be used continuously, and if any problems arise, they will help find a solution. The specific requirements for alarm devices vary depending on their place of use. Generally, they must meet explosion-proof standards, and a certification or test compliance certificate issued by the local metrology authority is also required; otherwise, the safety supervision agency may impose fines.
Don’t mislead the public; here are a few points to keep in mind regarding fire safety certification. 1. Fire safety mandatory certification (type approval) is a **official document that must be obeyed without exception or reason, just like the law – with no exceptions. Although the main responsibility lies with the manufacturer, in the event of an accident, the design institute, especially the end users, as well as the local fire safety inspection and supervision authorities, are all implicated ； (2) Although there are clear regulatory requirements and relevant authorities are in charge of oversight, you know how China is – due to \"various reasons,\" \"national conditions,\" and \"specific circumstances,\" the probability of being caught violating regulations by the supervisory agencies is extremely low. So, as someone mentioned above, one could simply ask the manufacturer; but just because the manufacturer says there’s no problem, does that really mean there is indeed no problem? Only if the probability of the lie being exposed is less than 0.1%, and if doing this requires investment of money and time as well as annual supervision/spot checks, will SB actually go ahead with it! So, just to be safe, making mandatory certification a required deliverable would solve the problem – it’s that simple. Then manufacturers wouldn’t have any reason to complain. If nothing else works, just go and check directly on the CCCF website (I have to say, this was done quite well; good job!). If everything goes fine, then everything’s okay; but if something goes wrong, it’s all over ；
What was said upstairs is right; I’ve learned it.
When designing, design institutes only focus on the explosion protection rating and refer to the layout standards for petrochemical facilities. However, as a safety protection instrument, this product must possess 3C certifications, explosion protection features, and measurement-related certifications. These are not requirements imposed by design institutes; rather, selling such a product without these certifications is itself against the regulations. Of course, China is so vast, and there are far too many instances of skirting the rules. When nothing goes wrong, everyone turns a blind eye ； For combustible gases, they are now subject to 3C mandatory inspection, and fire safety inspections are also required; it’s better to choose products from reliable suppliers that have relevant certifications.
