Choirone gas was a poison gas used in world war 1. If chorine gas was released into the air people may be exposed through skin contact, eye contact or breathing air contains chlorine. Chlorine gas is heavier than air, so it would settle in low-lying areas.
The extent of poisoning caused by chlorine depends on the amount of chlorine a person is exposed to, how the person was exposed, and the length of time of the exposure. When chlorine gas comes into contact with moist tissues such as the eyes, throat, and lungs, an acid is produced that can damage these tissues.
Burning pain, redness, and blisters on the skin if exposed to gas. Skin injuries similar to frostbite can occur if it is exposed to liquid chlorine
Burning sensation in the nose, throat, and eyes
Coughing
Chest tightness
Chest tightness
Difficulty breathing or shortness of breath. These May appear immediately if high concentrations of chlorine gas are inhaled, or they may be delayed if low concentrations of chlorine gas are inhaled.

When liquid phosgene is released, it quickly turns into a gas that stays close to the ground and spreads rapidly. Phosgene gas may appear colorless or as a white to pale yellow cloud. At low concentrations, it has a pleasant odor of newly mown hay or green corn, but its odor may not be noticed by all people exposed.
Coughing
Burning sensation in the throat and eyes
Watery eyes
Blurred vision
Difficulty breathing or shortness of breath
Nausea and vomiting
Skin contact can result in lesions similar to those from frostbite or burns
Mustard gas was effective because it was debilitating. Its mortality rate was only around 2-3% of casualties, but those who suffered chemical burns and respiratory problems due to exposure were unable to return to the front and required extensive care for their recovery.
Eyes: irritation, redness, burning, inflammation and even blindness
Skin: itchy redness that is replaced with yellow blisters
Respiratory system: runny or bloody nose, sneezing, hoarse throat, shortness of breath, coughing, sinus pain
Digestive system: abdominal pain, diarrhea, fever, nausea and vomiting
Tear gases weren't designed to kill; rather, to incapacitate the enemy and render them unable to defend their positions. They are all lachrymatory agents – they cause crying. They also irritate the mouth, throat and lungs, leading to breathing difficulties. Exposure to larger concentrations can lead to temporary blindness, but symptoms commonly resolved within 30 minutes of leaving affected areas.
Tear gas was the first chemical weapon to be used. It was a non-fatal irritant, and the first to use it in WW1 were the French, who used 26mm grenades filled with the gas on August 14th, 1911.
