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.
The real answer is it depends, but a total time of 25 - 30 minutes for a smaller tri-tip is usually a good starting guess. Each tri-tip roast and grill is different though, so you really need to use a meat thermometer to make sure the roast is cooked to perfection.
