Things are literally hotting up on the general election campaign trail.

Dublin firefighters were called to an election poster on fire in Kilbarrack on Thursday afternoon.

In a tweet, they are reminding people that posters are generally attached to public infrastructure - such as street lighting - and fires like these can cause damage.

Rules governing the placement of election posters falls under the remit of the Department of Communications, Climate Action and Environment.

But Dublin City Council notes: "It has been our experience in previous elections that numerous complaints have been received from motorists and pedestrians in relation to safety issues associated with election posters."

Its own staff have also raised a number of concerns.

The main issues are that posters that are blocking the visibility of traffic or pedestrian signals and traffic signs.

Many of the problems are caused by posters that are put up on poles adjacent to signals or signs.

Other issues arise when posters are below head height or resting on the ground.

"These posters can cause obstructions on footpaths and are particularly hazardous to the visually impaired", the council adds.
