At 3:20pm today I was in the lunchroom taking a break when someone yelled over the P.A. system "FIRE ON #3 LINE! WE HAVE A FIRE ON #3 LINE! SHIFT SUPERVISOR TO #3 LINE IMMEDIATELY! WE HAVE AN OVEN FIRE!" It's protocol to announce any fire three times over the PA system to get people into action and this one sure did. A major fire erupted out of the #3 egg carton dryer oven which is about the size of a freight trailer and about 100 or so feet long.It is used to dry the egg cartons that are produced from recycled paper stock. The shift supervisor upon seeing how big and how fast the fire started ordered everyone on the production floor and even the downstairs shipping and warehouse area not actively involved in attempting to fight the fire into the fire safe-zones we have designated. A few guys were busy emptying 20 lb. dry chemical extinguishers into the oven while myself and another fellow were manning the 200 pounder while another crew was attempting to put the foam unit into action. It was then that the supervisor ordered ALL of us to vacate the area and await instructions from the fire dept chief that was just arriving. He ordered a complete evacuation of the entire plant including the office area at the opposite end of the plant. In all there were at least four fire departments that responded to the fire. No one was allowed back into the plant to even collect belongings. Word has it that the shift has been cancelled for tonight, tomorrow, and tomorrow night at least. Perhaps I will go back on Wednesday unless told otherwise. Thankfully nobody got hurt but a couple of us sucked in a little too much smoke and dry chemical powder but are doing OK now. (cough cough hack) Man, that is the second fire at work I have seen that was of major concern with this being the worst a lot of people have seen in years. No word yet on what caused it but I am sure we will find out in a day or two.A day or two of lost income is better than lives lost that's for sure.The one good thing about the company I work for is that they try and give people work even when things slow down even if it is just cleaning up the machines and such. Looks like there may be a fair bit of that over the next few days.
