I read that the initial call was for a structure fire at the castle, but I’ve also heard it went out as a brush fire, so that’s obviously a huge swing. I saw videos of firefighters in full structural PPE, so I’ll assume it went out as a structure as there’s no need to don full turnouts for a brush fire. So if that’s the case I’d expect at least 3 engines, at least a ladder, and at least a chief. The only reason for ems units to respond is to boost manpower unless they’re sent as a rehab or dedicated for patient care, which you wouldn’t expect for a brush fire.
I didn’t mean to insinuate you were saying anything about daily use of mutual aid agreements, that was just pointing out that the article seems to claim mutual aid is being used more often than intended.
