Revealing mistake: At the house fire, after Roy and Johnny go upstairs to rescue the invalid woman, Captain Stanley and Chet head to the front door, and just before Cap kicks in the front door, we can see that the door isn't actually closed, it's just ajar.
Continuity mistake: When Dixie is having a heart to heart talk with Karen, in the shot facing Dixie she reaches out with her left hand to take the napkin from Karen, but in the closeup it's her right hand that takes the napkin. Additionally, the napkin she takes from Karen is perfectly folded, but it was wrinkled and messy when Karen held it.
Continuity mistake: When Karen first walks into Station 51, her handbag is over her right shoulder, then over her left shoulder and back to her right shoulder again.

Other mistake: When Johnny prepares Chef Michel's recipe, he leaves the casserole dish in the oven while Station 51 is dispatched to the structure fire. When he and Roy return, Johnny opens the hot oven door to find it smoking and the dish bubbled over, and even though the oven door is supposedly very hot, Roy places his hand on the inside of that door and actually leans on it like there's absolutely no problem.
Pressure 165 - S5-E7
Continuity mistake: While Johnny and the doctor are in the pressurized chamber with the diver, the guy outside the chamber tells them that they're at 165 and vetting, as he holds the mic up to his mouth with his left hand, but when it cuts to the interior shot, the mic is held up in his right hand.

When dispatch calls on Engine 51, the rest of the guys start to pile out of the kitchen, but in the next overhead shot the guys are actually exiting the doorway that leads to the locker room, not the kitchen. The interior of Station 51's setup when facing it is, to the right are Captain Stanley's office and the kitchen, and on the opposite side to the left are the sleeping quarters and locker room.

Visible crew/equipment: When Johnny brings in the box and Chet removes the wrapping for the baby layette, note the unfinished set wall past Engine 51 in the apparatus bay, which we can see since the front bay door is open, but when Captain Stanley walks in telling John about the phone call, the front bay door is now closed, then when the tones drop that set wall can be seen once again.
