Can smoldering logs be transported safely

Yes you can. It's called a long match and here's an example of how to make one.

I've seen several variations on this theme but basically you want a method to hold the heat of the fire with a limited oxygen supply and insulation. You need some Oxygen to get to the fire to keep it smouldering and you need some fuel for that fire but the trick is just enough and not too much.

Pre burnt but extinguished wood also has advantages when starting fires. The wood will typically take a match a lot quicker than freshly cut or found wood. So it can be worth transporting this with you if you're in a situation where good tinder or fuel is scarce. but ensuring a log is completely out is hard. Wood can hold a lot of heat internally and hot wood is only lacking oxygen to turn into burning wood.

Obviously carrying around a fire has inherent risks. Like a lot of bushcraft you need to weigh up effort vs benefit vs risk. A long match is high risk and requires a lot of effort so it's only really useful in a situation where you need a fire fast and you will struggle for dry tinder, etc.

So, I can, but should I?

90% of the time your better off just building a fire from scratch where and when you want it. A simple bundle of good tinder and a fire stick is much more practical than a long match.

A long match can be very useful for transporting a fire short distances.

I would never ever put a long match in a car

Not inside anything you're in.

A smouldering fire is pretty much the worst thing for generating carbon monoxide. That will poison you. I'd include the boot of a saloon car (trunk of a sedan?) as there's normally plenty of ventilation between that and the cabin.

Another reason for this is in case it ignites something - you don't want to be too close.

As an absolute minimum, in a pickup or other open vehicle. I'd want something to serve as a fire bowl, held down with metal fixings in the bed, and a tight-fitting metal lid, fastened. And still not for long or too fast (airflow). Wrapping it in a fire blanket would insulate it and keep the air off it to some extent. Too little air and it will go out, but it should light again easily, maybe even by retaining enough heat to get tinder going.

The answers you've received so far touch on several key elements of this situation:

• Liam's answer nicely addresses the how of carrying burning embers around with you, though it's not strictly applicable to the question of salvaging an entire already-smoldering log from a fire-pit.
• Chris H's answer offers a fairly reasonable approach to carrying around a smoldering log in the bed of a pickup (and is quite correct that any variation on "smoldering fuel of any kind inside an enclosed vehicle" is a recipe for carbon monoxide poisoning, and as such is a hard no).
• rbsdca's answer highlights the hazards of keeping a smoldering log around in the first place (embers may go places you never expected, and wood can smolder a shockingly long time then burst into flame at some later point).

But What Is It You Really Want?

The question doesn't specify whether keeping the log smoldering is actually an objective, or you just want to salvage a log which happens to be smoldering when you get there. So:

1. If you really do want to devise a way to safely transport a log while keeping it smoldering, I'd say that Chris H's approach is on the right track, but I would take it farther. To really keep the heat trapped and properly control the airflow, I would suggest a metal box within a larger metal box, with some fiberglass insulation between the two. The whole arrangement should be firmly secured to the open bed of a pickup truck. You would have to experiment with adjustable vents in both boxes to let just enough air reach the log, and ideally the vents should be baffled to minimize the effect of driving speed on airflow. And even then, the risk that Lightness Races in Orbit pointed out about possibly getting a flash-up from built-up wood gas igniting suddenly when introduced to open air is still a possibility. Not to mention the chance of a traffic accident, with a box of fire in the back of a pickup truck and gas dripping, leaking, or spraying from a damaged vehicle...
2. If you just want the log, the task is much easier. Put a metal job-box (as tightly-closing as possible) in the back of your pickup, shovel a few inches of sand in the bottom, and then when you can't resist that smoldering log, you throw it in the box, bury it thoroughly with more sand, close up the job-box, and off you go. The combination of sand and closed metal box should smother the fire quite effectively. A fiberglass fire-blanket soaked in water or fire-retardant gel wrapped around the log on its way into the box could serve as extra assurance too, even if there isn't enough water available to douse and soak the log.

Oh, and also, I don't know where you live, but I wouldn't be surprised if many jurisdictions have laws against carrying a fire around in a moving vehicle. All in all, there's no circumstance in which transporting a burning log in a car or truck is genuinely safe or advisable, though there's lots you can do to mitigate the risk if you're really determined.

I’ve moved many smoldering fires and hot coals with metal buckets. They can be obtained easily and cheaply. I’d never suggest putting it inside the trunk of your car though.

One such as this:

What firefighter could resist a question like this?

As a rule of thumb, never kick a smoldering log to put it out, especially not in a dry environment where water is scarce.

Smoke is the byproduct of incomplete combustion, so if it's smoldering, it's burning.

Kicking a burning log dislodges burning embers into the air, where they can be carried further than expected and in many, unexpected directions. The same thing happens as the wood moves around while you're driving down the road with smoldering logs in the bed of your truck.

A better solution is to place the logs in a metal box where they will be partially deprived of oxygen, which is essential to combustion. This is going to result in a great deal of smoke, as combustion becomes less and less complete until the fire goes out.

Of course the best option and the only thing that should be taught to children is to put the fire out with water.

While I have your attention: It's quite common for houses to burn down days and weeks after a woodland fire event, because burning embers became airborne and get caught in air vents in the roof, under the eves of the roof, or in any other opening where they can go unnoticed.

The best way to protect your home against forest fires is to create a defensible space around your home, using least combustible materials in landscaping.
