This started about a month ago. Dad is 88.5 yrs old, in a wheelchair and down to less than 145 pounds. Some how he removes the fire extinguishers from the walls and one time pulled the pin and was spraying all over the floor. These are large fire extinguishers so for now they have been removed from the two exits he is at the most. His routine is to wheelchair walk to an exit and stare out the door. He never was a fireman, or in a fire. His AL doesn’t know what to do. About this same time he started carrying a blanket, or a pillow in his lap. This is not consistent behavior though. It occurred to me to try either hang something red or something else in that location to see his response. Any ideas would be helpful.
