• Circular letter ST-O-CL-005 “Pulverizer and Burner line Fire Operating procedures” – Highly recommend reading to learn about combustibles and coal/air explosive ratios.

• Technique of “putting out coal fires on unit”.

• Emergencies dial “Help” (4357) instead of 911 on “in house phones”.

• In case of fire – alarm will sound, listen for instructions, and evacuate.

• Weather and power outages – facility will instruct what to do.

Alstom/Duke - will discuss the actual data from upgrades at Miami Fort and Zimmer and their process for resolving pulverizer fires and the approach to the pulverizer program in general.

Big Sandy / Loesche – will discuss the progress and challenges of installing a rotating classifier.
