When hazardous waste aluminum ash reacts with moisture in the air to produce a small amount of ammonia, is it necessary to use a toxic gas detector?
How much do you mean by a small amount? Is the environment in which you handle these hazardous wastes enclosed, or is it an well-ventilated open area? I’m just asking this; there are no other conditions. I can tell you irresponsibly that you can choose whatever you want.
Setting up flammable and toxic detectors shouldn’t have anything to do with enclosed environments or similar things, right? Your replies are all about environmental protection issues; what I want to know are the details related to setting up toxic detectors.
Let’s test the handheld meter first to see what the readings are; if necessary, we can use a probe then
If you understand it that way, it’s as if I never said anything.
If there are toxic and harmful gases in the workplace, installation can be carried out based on the occupational risk assessment and the specialized design documents, if such requirements exist
I remember a famous saying from a teacher: talking about toxicity without considering the dose is nonsense. Therefore, concentration or the amount of leakage is the most crucial parameter; if you ignore that as well, then there’s really nothing left to say.
It is stored in a hazardous waste warehouse, with a storage volume of 200 tons. Even if the aluminum nitride content is only 3#, the absolute amount present in case of ammonia release is still significant. So the amount you mentioned is definitely not a problem. Under normal conditions, there is no ammonia, but it appears when something is abnormal; that’s why I’m asking whether it’s necessary to install a toxic gas detector in such situations.
Take a look at GB50493’s definition of toxic gases and the requirements in 3.0.1: installations should be provided when it is possible to reach the MAC/PC-TWA/PC-STEL/IDLH levels.
