I'll Fix It - S4-E2
Continuity mistake: When Station 51 is at the scene of the oil well eruption, underneath a house which was built atop an abandoned oil field, just after Johnny tells Roy that he thinks the whole foundation is slipping, it cuts to a shot of the front porch as one of the porch columns (and part of another) breaks and falls. However, when the guys finally free the trapped man and carry him out, all the columns are upright once again.
I'll Fix It - S4-E2
Continuity mistake: While Roy and Johnny are under the house with the oil eruption trying to free the trapped man, they get covered in black oil and mud even though they're wearing turnout coats. It drips down their necks and their pants are soaked with it. When they get to Rampart with the victim, Roy says that he and John should get washed up, but when they talk to Dixie they haven't just washed up, their clothes are now impossibly spotless.
Continuity mistake: At the scene of the traffic accident involving the car and the armored truck, the chrome center of Squad 51's lightbar is backwards, the solid side is facing front and the vertical slats are facing the rear.
Continuity mistake: While the boy who has cyanide poisoning is in the ER, Dixie looks through his clothing and finds carved peach pits, and when she directs Brackett's attention to all the carved pits, the items change when it cuts to the closeup. Additionally, that closeup starts out being farther, and we can see that Dixie is not beside the table before it zooms in.
Continuity mistake: When Station 51 is being dispatched to the fire and explosion at Martell Industries, the other companies called are Station 36 and Engine 14, but we see Engine 236 at the scene even though they were not called. This is before Captain Stanley asks dispatch for the second alarm.
Continuity mistake: During the fire at Martell Industries, when Roy and Johnny make a mad dash out of the building before the explosions, and midway Roy's helmet falls to the ground as he keeps running, but in the next shot when he and Johnny reach the engine and dive to the ground, the helmet is hanging around Roy's neck.
Continuity mistake: At the start, when Chet tacks the notices up on the bulletin board, the papers are tacked to the board differently between the closeups and wide shots.
Continuity mistake: During the fire at the chemical plant, the distinctively marked SCBA tanks that Captain Stanley, Johnny and Roy are wearing, when they're searching for the missing man, change when they're inside and then finally exit. Note the different stickers, or lack of stickers, on their tanks.
Continuity mistake: When Johnny and Roy are treating the officer, while hiding between the bakery truck and car, the sniper fires at them which leaves multiple bullet holes on the side of the truck. However, when Vince talks to the Sergeant on the handie-talkie and then fires the tear gas, all the bullet holes on the truck are gone, but they soon reappear.
Continuity mistake: The window from which the sniper is firing sustains damage with broken glass panes, but then the glass panes are whole and intact, and then they are broken again.
Continuity mistake: When Gage goes into the lion enclosure you see the lion up high roar with sharp white teeth but the other shots the lion is now an older lion with broken rotten looking teeth.
Continuity mistake: At the lion pit, when John loads the photographer onto the stokes he places the yellow blanket package under her head, and as Captain Stanley, Marco, and Roy lift the stokes out of the pit, we can see that the package is under her head the opposite way.
Continuity mistake: When Dixie gives John a tetanus shot because he fell from a skateboard onto cactus, we know they're all in treatment 1, because when Johnny and Roy are at the open door we can see the door and wall (with fire extinguisher) on the opposite side of the hall, but in the next shot from the hallway he and Roy are leaving treatment 4, which is opposite treatment 3.
Continuity mistake: After loading the officer with the gunshot wound onto the ambulance, en route to Rampart when Johnny is checking the wound, Johnny's watch reads 11:10, but when he's adjusting the mask and the resuscitator regulator, his watch reads 11:55.
Continuity mistake: After the sniper throws the rifle out the window, Captain Stanley gives the orders over the HT to Engine 12, Truck 23 and Engine 23, and the next few shots of the rigs are from previous episodes including 3x7, "Promotion", when Roy and John rescue the security guard at the structure fire.
Continuity mistake: When John is in the lion's pit with the injured photographer, as he's loading her into the stokes his watch reads 3:40, but after they lift the stokes, when he's on the Biophone with Rampart his watch reads 12:15.
Continuity mistake: Roy and Joanne are going to be on a TV quiz show. When the guys are eating soup and sandwiches, Captain Stanley asks Roy, "You nervous about being on the tube tonight?" However, Roy didn't do the quiz show that night, because later we see they're on their next shift, and Roy is getting into his uniform when Johnny says "Tonight's the big night," and Roy tells him that Dwyer will do the rest of his shift when he leaves early.
Continuity mistake: When Station 51 is dispatched to 'vehicle accident with injuries', Roy is in the locker room still getting into his uniform with his shirt untucked and belt undone when re runs into the apparatus bay, but in the next overhead shot Roy's uniform is on properly.
Continuity mistake: When Chet and John are by the sink talking about Chet's appearance on the news, in the reflection we can see the three lockers behind Chet, and in the next shot the door of the fourth locker is wide open, blocking the third locker, and we can see that it's open because of the poster that's taped to the inside of the fourth locker's door.
Continuity mistake: When Johnny and Roy are with the boy who is in anaphylactic shock from the bee sting, Johnny's watch reads 2:25, then 2:35, and then 2:25 again.
