The folks that work EMS know the extent of the jobs they do when it comes to dirty. When dealing with public pain and suffering it would be improper to put such scenes on TV.
That said, folks in the EMS fields must have a sense of humor, rather grisly humor, or else go nuts.
My personal dirtiest jobs came from fatal crash investigations. I spent 12 years investigating accidents. Not pretty sights.
While riding with an agency which shared jurisdiction with mine, our unit was dispatched to a fatal crash, single occupant. The officer I was riding with was a veteran of his department and as we arrived on scene he recognized the first, and only, officer on site was a young man on his first week away from his field training officer.
The victim had not been wearing a seatbelt when she lost control and skidded into a telephone pole. She was thrown to the passenger side of the car where her head was smashed between the door frame and roof of the car. Brain matter was all over the interior of the car.
My partner took a piece of ham and cheese from his sandwich and placed it on a corner of one of the door arm rests. When the rookie officer came over the conversation turned to the various bits of gore and when asked what is all was, my partner picked up the piece of ham and cheese, ate it, shrugged and replied he didn't know.
Well, we thought it was funny anyway. The rookie didn't speak to us for a week.
Anyway...Here's to all the EMS professionals that daily go out and conduct themselves with honor and pride while performing some of the dirtiest jobs out there.
