First Due Arriving with a Working Fire Commercial Structure
You've arrived at a Commercial Building, occupied by a Laundry and Cleaners.
The fire is reported in the rear storage area of the structure. The building is occupied and operating. The structure is a Type III building, built in 2002. There is moderate, escalating smoke conditions, visible fire, with the first due engine just getting into operations and pulling a 2.5 inch attach line into the rear. The alarm response is robust, with Three Engine Companies, One Truck Company, One Heavy Rescue Company, One EMS(ALS), Two Battalion Chiefs. Suppression company staffing; 4 per apparatus.
What are the strategic and tactical issues affecting this incident?
Discuss the safety considerations and risks that must be assessed and planned for in the IAP?
What's the worst that you must anticipate?
As the incident expands, within 15 minutes of incident operations, fire self vents through the roof. You have multiple companies operating within the interior.
What's are the issues, assignments, concerns and needs?

Richard, just curious...
How do you reconcile "big water" with "manage run-off"?
Those two options are mutually exclusive, at least for most fire departments.
What's your thinking on this?
Thanks,
Ben

Had to leave last night & couldn't find this discussion when I got back to the computer. I am agreeing with the surround & drown method but from the looks of those pictures, the fire department didn't agree. There is too much fire through that roof & it could collapse @ any time with that equipment on top of it.

Well to start off, the strategic plan is marginal. And what I mean is I would start with the 2 1/2" attack with one company while the others are preparing for a deffensive attack. Once the defensive preperations are made I would get a statis report from interior crews. If they think they have got a knock on the fire then great, but if more time, resources are needed, sorry but we're done. To many tactical issues with a Type III and Cleaners to commit firefighters to. Type III's have many combustible voids and judging by the pictures smoke is coming from mortor joints, an indicator of collapse and weakened structure. Also the hazmat contents with a cleaners is a concern. With the water that must be used to extinguish we have a run off issue here as well. As the incident escalates then we have to pull out crews if interior operations are under way and go defensive.
So, interior right away but more for recon reasons.
Set up for defensive attack
Start second alarm with HAZMAT companies added to it
Watch for water containment issues (storm drains, etc.)

Hey Todd. Fantastic job recignizing the smoke from the mortor joints. It wasn't until you noted that, that I noticed it. On first look, I thought it was roll up smoke from the windows.
My approach would be much like yours Todd. I am immediately planning for structural collapse. Too many signs of trouble. However, I would start with a 2 1/2" in the rear but be more than ready for defensive operations. Unfortunately, the fire-load is too high to risk too much time inside the structure, not to mention the issues JUST with it being a Type III structure.
All-in-all, our Aerial would be getting some excercise on this one.
