Acute toxicity looks at lethal effects following oral, dermal or inhalation exposure. It is split into five categories of severity where Category 1 requires the least amount of exposure to be lethal and Category 5 requires the most exposure to be lethal. The table below shows the upper limits for each category.
Lets start with the stuff you'll need: Gas Grill Cooking tri tip roast on a gas grill is simple if the grill has at least two burners, and can maintain 350-375Â°F/177-191Â°C. Use an oven thermometer to assure an accurate reading. The one included on the grill is not accurate enough for good barbecue results.
Step 3: Roast the Meat. Place roasting pan on the center rack of the preheated oven for 20 minutes. Reduce the heat to 350 degrees Fahrenheit and bake for another 20 to 40 minutes (20 minutes for rare tri-tip; 25 to 30 for medium-rare; and 35 to 40 for well-done). Note: Bake times will vary depending on thickness of meat.
