(a) Neither a local public entity, nor a public employee acting in the scope of his employment, is liable for an injury resulting from the condition of fire protection or firefighting equipment or facilities. Nothing in this section shall exonerate a public entity from liability for negligence by reason of the condition of a motor vehicle while it is traveling on public ways.
     (b) Neither a local public entity nor a public employee acting in the scope of his employment, is liable for an injury caused by an act or omission of a public employee while engaged in fighting a fire. However, this Section shall not apply if the injury is caused by the willful and wanton conduct of the public employee.
