Guardrail vs Sawzall

[Trex]

Hi  all. 
Looking for tips and opinions.
Is there anyone here that use a sawzall to cut a (W) guardrail during a recovery?
I have a Dewalt flexvolt Sawzall and i was wonder if i can cutt a guardrail with a carbide blade lets say a diablo blade.
I have the Dewalt flexvolt grinder too but i was reading about the  the creation of zinc chloride/metal fume fever when using tools that cause high heat so i prefer to avoid this if is possibly  
Maybe anyone here have a picture or a video or tips.
thanks in advance

If we were to cut a guardrail or a cable barrier, we would be paying for it. The only thing we can do is move the guardrail or lift a cable barrier. Otherwise we must coordinate with the State, County and/or a contractor which installs. maintains and repairs these barriers. Often the vehicle remains until the obstacle can be moved. If we can remove the vehicle and clear the barrier we do so.

 We start by removing the nuts and bolts before having to cut. If it is disassembled it is easier to be replaced by guardrail company.  We have cut both ways but chop saw with 10" blade is best.

We have had to unbolt the guardrail and move it. Once had a truck with a piece stuck in it. In that case fire rescue cut it and the remaining piece we had to take to their station.

We had to cut a section a while back and I had only a sawzall... it cut through the rail section like butter.   I had been expecting it would tear up blades in a hurry but I didn't have anything else on scene.

Galvanized coatings do indeed emit a toxic plume of fumes once they reach a certain temperature. It is always best to have fire rescue cut this type of a metal, as they have the proper PPE. One does not want to expose your staff to anything that can be prevented. Galvanized coatings emit these fumes when they reach a certain temperature.

Thanks to all  who share their knowledge.

 

Just to be clear , in my country (Panama)  things are little different.

I am a person that always try  to be most prepared possibly.
The ideal situation is just go grab the car and go, but sometimes we all know its not work that way.

 

If a semi or a tractor trailer gets stuck between the guardrail theres nobody  from DOT or transit or fire rescue to free the car, must be me. 
The only way if  they are a person trapped inside the car firefighters takes the job and proceed, but only to save the live  not to free the car for the wrecker service  if not they dont touch the car.

 

And i agree 100% im always try to release the bolts on  the guardrail first  to try to free the car and works great but not always is possibly.

 

So in my truck im carry a flexvolt sawzall and a grinder too.
And im curious if anyone has cut the guardrail with the sawzall.

 

I bought some diablo blades thick metal and in past days i test the blades but i think that  are not the correct blade for the task i think they are too agressive because the sawzall vibrates alot.

 

Maybe i need something less agressive lets say a blade with 14 tpi.
So with the grinder if cut well but i read that fumes are not healthy so i try to avoid the most possibly.

 

In my free time i go to my shop and try to practice the most possibly to be prepared.

Again the ideal situation is just grab and go  but in the towing bussines  not always happen that way.

 

Glad to hear experiences for the towbrothers around the world.

The other thing to consider is when an accident happening the guardrail have a lot of pressure i need to find a way to cut throught the metal trying to avoid get the blade stuck between the metal.

 

Lets see,  i have experiments to do in this week lol.

Thanks to all and sorry if you read something weird english is not my primary language
