What alternatives did soldiers use during World War 1 to avoid being gassed?

During World War I, soldiers used various methods to protect themselves from gas attacks, including improvising gas masks from cloth or other materials soaked in chemicals like bicarbonate of soda. Some soldiers also sought refuge in dugouts or trenches, which provided some level of protection from gas clouds. Additionally, troops were trained to quickly seal off their positions and use available equipment, such as respirators, when gas alarms sounded. Overall, these measures were often rudimentary and highlighted the inadequacy of early protective gear against chemical warfare.
