Continuity mistake: After the woman has staggered into the ER she is seated in the wheelchair, and when she jumps out of the wheelchair there is a tall ashtray can behind her beside the wall, but in the next shot that tall ashtray can has vanished.
Continuity mistake: After Station 51 is dispatched to the fire/explosion at the chemical company, when John heads inside to rescue the chemist, the SCBA cylinder he's wearing has one white sticker and one pinkish sticker. By the time John brings the victim out to the sidewalk, his air tank has changed back and forth repeatedly to one that has two red stickers.
Visible crew/equipment: Just before the hermit leaves Rampart, the actor's mark is visible on the floor in front of the market owner's feet, and when Dixie turns the hermit's wheelchair, the tape mark in front of Brackett becomes visible.

Visible crew/equipment: At the abandoned refinery, just after Roy attempts to pull out the man pinned under a tank, but is unsuccessful the first time, when it cuts to Captain Stanley and Chet, who are on the third level hosing the fire through the doorway, at the left of the screen a crew member is visible, watching them.

Visible crew/equipment: When Roy moves the squad forward to tow the wrecked car away from the flames, as he opens the driver side door to get out, we can see the reflection of the silver reflector screen in the squad's long wing mirror.

Visible crew/equipment: When Engine 51 first arrives at the abandoned refinery and stops to hook up to the hydrant, the multiple location set lights are reflected on the engine's large windshield.

Revealing mistake: When Johnny and Roy are figuring out how to free the woman trapped in her wrecked car, the flames spread and Johnny's pant leg catches fire, but as he's trying to smother that flame, the strip of fire stunt gel that was smeared on his pant leg is visible.

Other mistake: When Station 51 is dispatched to the traffic accident, while en route first we see Engine 51 with nobody on the back, but then we see two firemen standing at the back, and they are Johnny and Roy. This footage is from the episode "The Old Engine" in season 3, when Station 51 got the new Ward La France engine, and since the previous shift was still out with the squad, Cap told Roy and Johnny to jump on the back and join them on their first run with the new engine.

Continuity mistake: In the opening rescue where Roy and Johnny rescue the woman from the burning car, Johnny is relaying the woman's vitals to Rampart. Over his right shoulder, you can see a sticker on the trunk of the car behind them. This is probably a dealer sticker. In one scene, it is blue and red, and in another, it is blacked out. It returns to blue and red, only to be blacked out again.

Continuity mistake: After the ambulance Roy is riding in is involved in a traffic accident, when Johnny arrives he jumps into the back with the injured attendant and patient, and we can see that the stretcher's footrest is light brown. But when the attendants exit, they carry the stretcher out of the back of the first ambulance then wheel it to the second ambulance, and the footrest is now red. It would seem that they merely transferred the patient from the first ambulance's stretcher to the second ambulance's stretcher while still in the ambulance, but they couldn't have done that because two full size stretchers cannot fit into the back of that first station-wagon style ambulance, especially with attendants back there, so they would have had to do the patient transfer on the ground outside. Hence the problem.

Continuity mistake: The cut that Roy receives over his eyebrow during the traffic accident changes characteristics, such as when he and John are at the poker game, it looks considerably better in following shots, then it looks much worse again.

Continuity mistake: Just before the ambulance Roy is riding in is involved in the collision, we see a crowd of people at the corner near the stop sign, but in the next shot they've all vanished, only to reappear just as the vehicles collide.

Continuity mistake: After they load the woman from the wrecked car into the ambulance, Roy and an ambulance attendant are riding in the back with her. In the shots of the moving ambulance, until it's involved in the traffic accident, we should be able to see Roy and the attendant through the windows, but they're simply not there.

Visible crew/equipment: When the ambulance that Roy is riding in is involved in a traffic accident, the ambulance driver, Hal, comes out to help, and the outline of the mic transmitter is visible on the back of Hal's white shirt.

Continuity mistake: When the victims are loaded onto the second ambulance with Roy, after the original ambulance was hit by the car, we can see the license plate, Z99977, as Johnny closes the back doors. Then while en route to Rampart, the ambulance's make/model changes with plate, Z99953, then the make/model changes yet again, but still has the same plate, Z99953.
Other mistake: When Roy and Johnny are at base camp during the fire, they're dispatched to the incident at Jawbone Canyon. While en route, Battalion 5 orders Engine 51 to approach from the north, and we hear Captain Stanley respond, "Engine 51, 10-4," but it's odd that the subtitles read that Johnny is the one who responds. Later, after Tanker 44 tanks 51, Chet says, "Cap, we've got a charged line," but the weird subtitles read, "Captain's going to throw us a line." Subtitles from Universal Studios 2010 DVD.
Other mistake: At the start, when Roy is reviewing the list making sure he got everything, there are two containers of milk on the counter which have their brand names covered. As an aside, watch Chet as he empties the grocery bag and puts the aluminum can in the freezer.
Other mistake: Just as Squad 51 reaches the Tank Motorway, in the shot of the squad as it drives towards the camera before it zooms out, look at the squad's license plate before it stops. Even through the haze, we can see that the plate number is not Squad 51's normal E999007.
Continuity mistake: While the judge and young lawyer are doing CPR to help, Roy's tearing off strips of tape and placing them on his pants (for IV as usual), then after he asks Johnny, "Were you able to get in touch with Rampart?," in the next shot all those strips of tape have vanished from his pant leg, only to reappear when Roy defibs the patient.
Other mistake: When Battalion 5 orders Copter 10 and Copter 14 to make an air drop on Jawbone Canyon, it cuts to a shot of Copter 14 taking off. This is the same shot used in S3, E6, "Snakebite", when 85's guys tank Copter 14 in order to make a water drop where the teenagers' car is on fire down below.
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.
