Is it necessary to install an oxygen alarm?

Is it still necessary to install an oxygen concentration alarm in the plant where pressure swing adsorption oxygen production takes place? Last edited by hw197358 on 2009-3-2 20:38]
Inhaling highly pure oxygen is also not good, as there is a risk of leaks; therefore, a unit should be installed.
There is no need to install an oxygen alarm, as alarms are required in areas where flammable gases or toxic gases are present. Oxygen is an oxygen-supplying gas; it is neither flammable nor toxic
No settings are needed; in fact, I’ve never seen one either, as accidents caused by oxygen leaks are very rare.
Is there any specific specification or standard that requires this?
I think it should be installed, because high oxygen concentrations can lead to fires when in contact with oil stains and similar substances.
The MSDS for oxygen states that \"this product is non-flammable,\" yet oxygen is actually a combustion-supporting gas; this is indeed a problematic issue. Personally, I think there is no need to install sensors. Since oxygen is present everywhere in the atmosphere, if a sensor is to be installed, it should be set up to prevent anaerobic conditions by monitoring oxygen concentration levels.
Personally, I think it depends on what the space is like; if the space is too small, then it’s necessary to install it, but if natural ventilation is possible in that space, then it’s not needed!
Oxygen alarms are generally not necessary, but inhaling high concentrations of oxygen is also harmful; if conditions permit, it is still advisable to install one
Are there any relevant instrumentation devices? It doesn’t seem to be that easy to detect high-concentration oxygen. If such a device does exist, it would be good to add one, but it would be somewhat wasteful. Personally, I think it’s not necessary to add one, but ventilation facilities must be in place.
It shouldn’t need to be set, right? But at that time, when the space was small, it was possible for the oxygen concentration to become too high, leading to oxygen poisoning among the early workers.
It seems that too much oxygen is harmful to health; a device should be installed to put people first
Is there any specific specification or standard that imposes mandatory requirements?
Personally, I think it’s unnecessary to set it up. To date, I have not seen any devices designed for monitoring oxygen concentration; generally, regulations only set clear requirements for detectors and alarms for flammable gases and toxic gases. Oxygen is an oxidizing gas, and I have not encountered any regulatory requirements regarding it in this regard.
Our company is one of the leaders in the gas industry, and it is stipulated that oxygen detectors must be installed in areas with elevated oxygen levels, with the acceptable range being 19.5–23%
If financial conditions permit, I think it’s better to have one; in the presence of Mars, it will go out in the air, but it might resume burning when the oxygen concentration is a bit higher. If financial constraints are an issue, then attention should be paid to ventilation – safety comes first, as accidents can have serious consequences
If air circulation is poor, I think it’s still necessary
According to gas detection standards, it is not necessary to install oxygen detection
It is recommended to set a limit, as too high an oxygen concentration can easily cause suffocation.
