Crawley firefighters have joined a 24-hour national strike over changes to their pension scheme.
The crews walked out at 9am today (June 12) and will return to duty at 9am on Friday (June 13).
A seven-hour strike is also planned for Saturday June 21 from 10am until 5pm.
A spokesman for West Sussex Fire & Rescue said: “The Fire Brigades Union (FBU) is currently in dispute with the Government over changes to the Firefighters’ Pension Scheme and conditions of service.”
The spokesman said “robust” contingency plans were in place to cover the strike period and added: “However, during any period of industrial action the service would have fewer resources available and would be prioritising life-threatening incidents such as house fires and road traffic collisions where people are trapped.
“You should still dial 999 in an emergency but you can help by reducing the demand on emergency services, especially during industrial action.
“The message to residents, businesses, and people travelling in West Sussex during any possible strike action is to take extra care.”
