Calculate Your Basal Metabolic Rate (BMR)


You can use a TDEE calculator to find this number, or calculate it manually to get a more specific result. Keep in mind, though, that it's impossible to know your exact TDEE, as your activity levels will change day to day, and the only way to get 100 percent accurate BMR numbers is through laboratory testing.

How do welding emissions fit into your emissions inventory?


Most EPA inspectors used to pay scant attention to welding fumes; these days they warrant much more attention. Regrettably the EPA relies on AP-42, a document that is thorough in some areas but not too detailed in welding processes. This means an overly zealous inspector might rate your facility as emitting more than it really does, forcing you to implement expensive and unnecessary controls
