The Northern Ireland Fire and Rescue Service (NIFRS) is to cut crews to deal with budgetary pressures.

Documents seen by BBC News NI reveal that smaller towns are likely to be hit hardest.

Fire cover will move from full-time to part-time in a number of towns, including Carrickfergus, Enniskillen and Armagh city.

The fire service says the cuts are a 'temporary interim measure '.

"These temporary measures have been risk-assessed against the impact on both public and firefighter safety and will ensure a safe and effective service," it said.

The latest NIFRS staff numbers show there are 812 fulltime firefighters in Northern Ireland.

In a statement NIFRS said it "intends to bring a number of new trainees into the organisation over the coming months to allow for the continued delivery of a safe and effective service".

Members of the Fire Brigades Union said they are "outraged".

There is a budget shortfall of about £3.2m for 2019-20, according to the union.

'Template for disaster'

Union leader Jim Quinn said members have been briefed by senior management and it is probable that changes could take effect within weeks.

"We are shocked that it's emerged this is a template for the future - we say it's a template for disaster," he said.

"As a result, the public and firefighters will be at risk as there will be a reduction in services across Northern Ireland."

Belfast - where there are six stations with 11 appliances crewed on a full-time basis - is also affected.

The fire service added that one of those appliances, crewed on a full-time basis, will instead be staffed on a nine-to-five basis by a "resilience" crew, which will be based at headquarters in Lisburn.

"A specialist rescue team will crew it during the night and at weekends, dependent on operational need."

NIFRS said the measures would help to manage the budget in the short-term and also help assess any impact and inform any longer-term change while providing a safe and effective service.

The Fire Brigades Union also warned that specialist staff, including junior managers, are being asked not to do critical fire safety inspections in public buildings in order to fill rota gaps.

'Controls the purse strings'

Mr Quinn said the union would fight the cuts.

"We have been asking to meet the permanent health secretary Richard Pengelly but as yet he hasn't been in touch.

"It's important he meets us and listens to those on the front line as he controls the purse strings."

On Thursday evening, the union was told it would be fully briefed on the changes first thing on Friday morning.

Stormont's Department of Health said the fire service has been allocated a budget of £74.1m - an increase of £1.19m.

In a statement to BBC News NI, the Department added that the NIFRS was working to produce a break-even plan to support the 2019-20 budget allocation.

It said the union had written to Mr Pengelly on 5 July asking for a meeting and the request was being considered.

During 2018-19, the number of emergency calls handled by NIFRS increased by 5.6% on the previous year, to 38,511.

It also attended 24,586 incidents, up 2% on the previous year.
