I have been a Fire/Medic for over 20 years and 16 of these years have been at the same department. In the past couple of years alot of things have been changed to color coded. Since I am Red and Green color blind this has became some what of a problem for me. The Fire trucks have color coded hand lines and if some one in the fire says red line needs more water then I have to be know which one that is. My question is can they use this against me and could I loose my job after 16 years doing and bieng color blind? Most of the guys I work with know I am color blind but I just dont want something to happen that would get someone hurt.
