I had pulled on turnout pants over bunker boots my preferred get up, my personal Globe fire coat with its Scotchlite reflective yellow JB on the back, because the issue jackets were always too short, and my MSA yellow topgard helmet with the blue two inch reflective 37 on each side. Jeff donned his black MSA helmet, his issue coat and he pulled up his boots.
After forcing entry by cracking the swinging heavy tempered and locked glass doors, while the interior was illuminated from the outside and with the inside lights, the two of us started slowly down the main aisle. I had the nozzle with my right hand on the hose, while Jeff walked behind me pulling and keeping the hose line taught.
While walking along and watching for anything untoward we saw no evidence of what we would soon encounter. There was no warnings felt or heard, just the fading sounds of pumps, shouts and radio calls broadcast over the external speakers.
We reached the end of the aisle and turned right where we spotted the concrete stairway leading to the basement. From the top of the steps I could see two swinging doors with an orange/yellow glow appearing behind the two glass windows.
We started clomping down those steps with their rubber inserts.
About halfway down, the doors blew open with a growing fireball expanding outward and upward. I turned to Jeff over my right shoulder and hollered, “We’ve gotta back out.” With eyes as big as saucers he nodded and we walked up the stairs backwards. Luckily, Don Shelley was in the exterior doorway and began pulling the line outside when he noticed our retreat once we made it to the main aisle.
As we stopped briefly with the long display counters on both sides of us, the flames grew from floor to ceiling and we began backing out with a bit more rapidity, one of the more difficult retrograde maneuvers in firefighting when you retreat in the face of a rapidly expanding flame front stopping your forward progress.
