We always wait at least 15 minutes before putting the heat pack into our packages to ensure they are working. There have been a few times that the heat pack has died short of the 40+ hours it was supposed to last, and also it only warms the package up about 15 degrees higher than the air in the box. So if the box was placed outside or in the back of a airborne van that had no heat and was very cold it would not warm it up.
We did experiments with our boxes last year and put a thermostat into a box with a heat pack. We then left it at room temp, put it outdoors in the cold, and then put it in the freezer to check. Well when it was at room temp the temp in the box only got to about 84 degrees, when it was outside in the cold it barely made 80 and then in the freezer it died completely until taken out of the freezer and the air in the box was allowed to warm. These boxes were all with 3/4" foam lining, plenty of packing materials and a 40+ hour heat pack.
Please don't think I am trying to shift blame on him in the least as that is not the case. That wound was not a fresh wound and if he did not see that when packing the animal when he must have had his eyes closed. All I am saying is that the heat packs are not 100% reliable to keep the inside of the box warm. Also depending on what the temps are and the size of the box I use multiple heat packs. That way if one should fail the other will be a back up.
