WEST YORKSHIRE Fire and Rescue Service (WYFRS) has joined an online viral challenge by opening up to the world.

The "Tetris Challenge" sees emergency services and responders across the globe showing the general public what is contained in their vehicles.

WYFRS have got in on the act, posting on social media site Twitter with a picture to highlight what the fire service carries in one of its fire engines.

The post said: "Ever wondered what we carry on one of our fire engines?

"Well here it is...our attempt at the Tetris Challenge."

The picture shows one of the WYFRS crews arranging their gear - and themselves - in a block like formation.

Looking like a deconstructed Lego-set, the challenge follows a phenomena known as "knolling".

It is described as: "The process of arranging related objects in parallel or 90-degree angles as a method of organization."
