Continuity mistake: When Johnny adjusts his IV after the snakebite, he tells Captain Stanley that he's ready to leave, and Chet is not wearing his helmet, but in the next shot as Marco heads for the squad Chet is wearing the helmet.
Continuity mistake: When Johnny is bitten by the rattlesnake he's holding the handie-talkie, but then he drops it and the HT falls to the other side of the car, as he hoists himself up against the car door. However, when he sits down on the ground he is still holding the handie-talkie.
Continuity mistake: When Station 51 is dispatched to the car over the cliff at Bear Mountain, the timeout is 08:12, then when Roy contacts Rampart his watch reads 6:55. When Johnny checks the girl who can't see, his watch reads 12:45, but when Johnny contacts Rampart his watch reads 6:05. Then after the snakebite, when the guys carry Johnny to the back of Engine 51, Johnny's watch reads 10:35.
Revealing mistake: After the snakebite, when the guys carry Johnny and place him at the back of Engine 51, the chrome spotlights are shiny and reflective, but in the closeups the spotlight near Marco has been partially sprayed with a dulling spray, to prevent the camera's reflection.
Continuity mistake: At the scene of the traffic accident, when Johnny tries to calm the woman who cries that she's afraid, it cuts to a shot of Chet as the camera pans to the left, and we see the position of the pickup truck on the road. When they hear the siren of help coming, Chet stands in the road directing the vehicle, and the pickup is not where it was in that earlier shot, it's now much farther down the road.
Continuity mistake: At the start, there's a closeup of Roy, Johnny, and Chet, and it cuts to a long shot of the landscape around them while they're driving, then it cuts back to the closeup. The landscape the Land Rover passed in the long shot is entirely different than in the previous and following closeups.
Continuity mistake: When Roy and Chet go to Rampart to visit Johnny on their day off, Dixie tells them that Johnny's in room 205, but when Chet and Roy walk in the number on the door is 230.
Continuity mistake: When Chet flags down the young driver to get help for the traffic accident victims, the driver's side wing mirror is tilted out at a wide angle in the long shot, but in the next closeup the wing mirror has been pushed flat up against the car, so as not to block the actor during the conversation.
Visible crew/equipment: After Roy, Johnny, and Chet find the victims of the vehicle accident, when Johnny checks on the boy's mother, the bulging outline of the mic transmitter is visible on the back, right side of Johnny's red shirt.
Visible crew/equipment: During the structure fire, Johnny and Roy rescue the security guard, and when Roy breaks the window with the chair, we can see a couple of crew members, equipment, and lighting on a tripod, outside down below.
Visible crew/equipment: When Squad 51 is heading to 1511 West Hill, responding to the attempted suicide, in the closeup of Roy and Johnny en route, we see the reflection of Squad 51 as they're driving past houses/stores on Johnny's side. Just about as Roy says, "It should be it over there," in the reflection we see two crew members riding on the squad - one on top of the squad, and the other one standing on the back.
Other mistake: When John and Roy get back to the station, they head to the kitchen and John takes the hot pot of stew out of the oven with potholders, and when he quickly tries to lift the lid without the potholder, his pain makes it clear that it's burning hot, so he uses the mitt to lift the lid. There's a long metal serving spoon that was left in the stew, and John just lifts it up and starts serving the stew with no problem, even though that spoon should have been too hot to even touch.
Continuity mistake: After Roy's had his arm bandaged in the ER, Brackett points to the treatment room Johnny's in and says he's in 4, and Roy heads there. Then after speaking to Johnny, when Roy opens the door to leave Johnny's treatment room, we can see the treatment room facing Johnny's, and it's treatment 2, which means that Johnny is actually in treatment 1, not 4. Plus the fact that the boy with the heart problem is supposed to be in treatment 1 at that time.
Visible crew/equipment: At the structure fire, after the security guard is safely down the ladder, Johnny follows him as Roy watches from the window, and when the fire flashes through the doors, we can see the hand of a crew member pushing the lower boxes causing them to tumble.
Continuity mistake: In the opening scene when Johnny and Roy walk into Captain Stanley's office, Johnny's pack of cigarettes is in his right shirt pocket. As he and Roy are talking in the apparatus bay, the cigarettes are still in his right shirt pocket. When Johnny enters the kitchen after Roy, the cigarette pack has magically moved to his left shirt pocket.
Revealing mistake: During Station 51's rescues on the foggy San Diego Freeway, when Chet is giving CPR to the little girl, it's just too obvious that he's not really giving CPR, unless her mouth is located on her cheek.
Visible crew/equipment: After Roy breaks the window with the chair, the guys place the ladder against the window and Marco starts to climb up. In the next interior shot, just as Roy and Johnny lift the security guard, right outside the window we can see the corner of something else (platform-like), besides the top of the ladder.
Visible crew/equipment: When Squad 51 arrives at the second location, 1511 East Hill, trying to find the correct address for the attempted suicide, the outline of Johnny's lav mic transmitter is visible at the back of his shirt.
Visible crew/equipment: While Early is listening to the heartbeat of the boy with a heart problem, Dixie is standing beside him, and on the glass case behind them we can see movement in the reflection, even though it's only the three of them in that treatment room.
Continuity mistake: During the structure fire, after the security guard has been carried down the ladder, in the interior shot when Johnny follows, he places his injured right leg out the window first, but in the next exterior shot it's his left leg which is out the window, then it's back to his right leg being first out the window.
Answer: I believe you are speaking of the old man, Mr. Wilson. He's played by J. Pat O'Malley.

Correct, it was J. Pat O'Malley...he also played the grandfather with his grandson when their rocket exploded, and also played "Old Bill" in the episode with Ann Prentiss, where Gage saves the little girl from the burning tree house, and her mother falls in love with him.
