Especially if the game is on the line when fourth official Sam Barrott raises the board on 90 minutes.
The Seagulls have conceded costly goals in added time during their last two Premier League games.
Before that, they scored early in stoppage time to earn a point against Bournemouth.
Hurzeler accepts emotions can be heightened when added time is announced.
He said: “Definitely there is something. But we still have to manage these minutes better.
“So that’s our responsibility, that’s my responsibility and we have to take ownership for that.”
Harry Wilson scored the winner deep in added time for Fulham and Beto left it even later to salvage a point for Everton.
Those moments cost three points in total and led to bitter disappointment after each game which has lingered into pre-Palace week.
Hurzeler said: “I think we have to play the last minutes of the game better than we played in the past.
“We have to be even more focused. We have to even focus more on the details. So that’s definitely something that we have to improve.
“Regarding the end of the game, if you are behind and you risk everything, you go all in to make the equaliser or to win the game.

Albion, with one win in 11 league outings, will be without midfielder Yasin Ayari but Diego Gomez, Matt O’Riley and Jack Hinshelwood are all added to the squad.

Hurzeler, looking for his first success against Palace, said: “There’s a big meaning in this game, not only for us as a team but also for supporters of the club.
“We want to try and get this win for the fans.
“They suffered a lot in the last weeks and it’s our responsibility to promise that we will be fully committed, that we will give everything and then we are convinced that we can get the win.”
