The NFPA 70E Standard details multiple levels of Hazard Risk Categories (HRC) [see table 1.1], also called Levels. The greater the risk: the higher the HRC. Arc Rating is the factor that indicates which HRC is necessary, and can be measured in either ATPV or EBT.
The optimal pH range for brook trout appears to be 6.5-8.0,with a tolerance range of 4.0-9.5.Brook trout occur in waters with a wide range of alkalinity and specificconductance, although high alkalinity and high specific conductance usuallyincrease brook trout production (Cooper and Scherer 1967).
Season brook trout fillets or butterflied trout lightly with salt and pepper or other flavorings, as desired. Season whole trout inside and out. Clean the bars of your grill carefully, and oil or spray them with high-temperature pan spray. Preheat the grill to medium-high heat. For pan-searing, place a heavy skillet over medium-high heat. Place the fillets or butterflied trout in an oiled fish grilling basket, and place them on the grill. If you're pan-searing the trout, add 1/2 tablespoon of oil to the hot skillet and put in your first few fillets or whole trout. Leave plenty of space between the portions and don't crowd the pan.
