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.
For the best cooking results, let it come to room temperature for 1-3 hours. 1  Tri tip is very lean, so leave the fat cap (about 1/4) to ensure a more flavorful roast. 2  If your tri tip has a heavy fat layer, trim it to 1/4. 3  Apply the rub liberally! 4  You can cook it immediately, or let it sit for up to an hour.
