As the Environmental Health and Safety Manager (EHS Manager), conduct a fire prevention and protection audit of the following assembly area:

It measures 80 feet by 140 feet.
There are currently two 2A10B:C fire extinguishers located in the center of the room on each of the short ends (40 feet on each end of the room). 
The room hazard level is rated as ordinary with moderate amounts of Class A Combustibles and only minimal amounts of flammable/combustible materials. 
Then based on the following information, provide a determination (you must show your math calculations) as to how many fire extinguishers are needed for this area and provide comments on their placement. 
Your company has several employees who are working along a conveyor line to clean up an over spill of product by manually shoveling the materials. The conveyor belt is located outdoors and will take several days to clean up. Given the following data Wet Bulb Temperature = 88oF; Dry Bulb Temperature = 93oF; and Globe Temperature = 91oF, calculate the WBGT Index. You must show your math calculations.
Due to the heat, the employees are only exposed for 190 minutes at this temperature over an 8-hour workday. Assume a 75oF exposure for the remaining 290 minutes. Provide a recommendation on the work/rest cycle based on the information and guidance in this unit. Include any assumptions in your analysis. Finally, discuss the concept of wind chill and calculate the wind chill in oF based on the following information below. You must show your calculations.
Air Temperature: 10oF and a Wind Speed of 12 miles per hour (mph)
