For example, because of the process in the confined space itself, it may produce toxic gas. The welding process may cause the risk of excessive oxygen (O2) or explosive gas accumulation due to gas throat or connector leakage. The high temperature process may make the harmful substances in the space evaporate, producing harmful or toxic gases (CO, SO2), etc. Therefore, if the risk assessment report considers that there is a potential danger of gas volatilization, the workers entering the confined space must carry a gas detector for continuous monitoring to ensure that once the gas in the working environment reaches the danger level, they can leave in time.
