Working in oil tank is very dangerous, because lack of oxygen will cause death.
Before entry, we need an portable oxygen gas detector with a pump to detect the oxygen concentration.
The pump can suck the gas in the oil tank from inside to outside. And then the detector tells if it's dangerous in the oil tank.
Features of oxygen detection alarm:
