Liverpool have issued staff with a list of banned phrases in an effort to get rid of discrimination in the stands at Anfield.
The list includes expressions such as "Don't be a woman", "Play like a girl", "Man up" and "That's gay", as well as a number of more explicit or offensive words.
The club have produced a handbook which highlights common slurs against race, religion, sexual orientation, gender and disability which could cause offence.
Liverpool's players receive their own guidance as part of a separate Premier League programme, and this latest move forms part of a wide-ranging programme to help other club employees identify discriminatory language that may be used by supporters on match days, reports Sky News.
"As part of the club's continued commitment to tackle all forms of discrimination, as well as promoting its approach to equality and diversity, Liverpool FC has been actively engaged in a full club-wide education and awareness programme," Liverpool's social inclusion officer Rishi Jain said.
"This programme includes interactive workshops and a handbook which is designed to provide information on the latest equality legislation including information relating to what terminology is deemed as both acceptable and unacceptable.
"This programme of awareness enables our employees to recognise inappropriate language and take the necessary steps to ensure Anfield is free from all forms of discrimination.
"Liverpool has been actively working with Kick it Out, Show Racism the Red Card and the Anthony Walker Foundation for many years and has been recognised externally for its contribution to helping tackle discrimination and promote Anfield as an inclusive and welcoming environment.
"The club has already attained Kick it Out's equality standard preliminary level and has recently submitted its application for the equality standard intermediate level demonstrating its continued commitment."
With the squad returning from their tour of Australia and Asia this week, it is likely the focus will soon again be on Luis Suarez, for whom the club have rejected a £40m plus £1 bid from Arsenal.
Liverpool has had problems with accusations of racism in the past.
Striker Suarez was suspended for racially abusing Manchester United defender Patrice Evra and Oldham defender Tom Adeyemi was reduced to tears after Liverpool fans targeted him during an FA Cup match
