It's to coincide with LGBT+ history month.
The video, launched this week, features some of the service’s employees.
It shows the staff members reading out some of the abusive, hurtful and homophobic comments made by people on Facebook after the organisation added a rainbow to its profile picture during Pride Month last June.
The service, which strives to be a diverse and inclusive employer, says it wants to show its LGBT+ staff, and communities, that they are valued and supported.
“We fully expect the video will have a mixed reaction but some of the comments we received last year were awful and totally unacceptable,” said Chief Fire Officer, Alex Johnson.
“We’ve produced it for two reasons – firstly we wanted to support the month and let our staff, and communities, know that we are proud to employ and serve them, regardless of those comments.
“And secondly we wanted to demonstrate that we are a genuinely inclusive organisation that values the contribution of all our staff, whatever their LGBT+ status.
“I’d encourage anyone considering a career in the fire service, especially those who may be inspired by our work around LGBT History Month, to register their interest on our website.”
