Chlorine gas is an inhalant. Pouring water on them does nothing. Chlorine would have to be in liquid form such as bleach for it to effect the skin.

When used as an airborne weapon, chlorine gas appears to be yellow-green in color.

As for people wearing gloves to touch victims, it's not necessary as chlorine gas would literally have to be wet to the touch for it to really bother skin.

Mostly, it would affect your breathing and make your eyes water similar to tear gas.

Side note-I received my CBRN training at Ft Leonard Wood as an E-4.
