AIBU about petrol container with broken cap?

[PetrolStorageQuestion]

NC because very outing.

The petrol can for our lawnmower had a crack in its cap. My wife refuelled her car and decided to refill the petrol can at the same time, despite this crack. She had ordered a replacement cap, but it has not arrived yet, so in the meantime she used a plastic bag underneath the broken cap in order to prevent vapours from escaping. She also feels that it is safer to store the full petrol can inside the house, because if it is stored outside behind our outbuilding, somebody might climb over a fence or gate, enter our garden, find the full petrol can, and use it to start a fire.

Upon learning this, I completely lost my rag and said that storing petrol in this was is extremely dangerous and I could not accept that; either I was going to go out immediately to buy a new, replacement container, even though we would then end up with an unneeded extra fuel container, or I and our daughter were going to sleep in a hotel until the new cap she ordered had been received and installed. DW clearly thought I was being unreasonable, but accepted for me to go purchase a container rather than the much more expensive alternative. This replacement purchase has now been made . It cost £8.99 and took me about 30 minutes.

YANBU: you were not overreacting by becoming extremely upset about this, because even with a plastic bag as a makeshift seal, storing petrol in the house, especially with a broken cap that could allow vapours to escape, is just too dangerous to be acceptable.

YABU: You overreacted by becoming so upset. It was a waste to buy another petrol can. The plastic bag solution would have been safe enough to make it OK to store petrol in this house for a day or two until the new cap arrived.

What a load of fuss over an £8.99 petrol can. You weren’t unreasonable to go out and get a new one but you were entirely unreasonable to “lose your rag” and talk about going to sleep in a hotel.

Although I now think, having reread the “outing” message, that I’ve fallen for some nonsense…!

I can't get over the fact you're concerned this is outing...

What a drama queen you are.

But now we'll get to see the deletion message!

They used to be witty/funny, they don't even try anymore.

You overreacted.

If she's cling filmed over the top and used the cracked lid too, I don't think anything bad would have happened . Saying you're going to stay in a hotel over night is extreme

Why do you need spare petrol?

You are right that keeping it in the house is a hard no

The chance of random firestarters happening upon your stash has got to be ridiculously small

The petrol shouldn’t be stored in the house, full stop. Even in a secure container. That’s just stupid. Honestly; grow a brain.

Petrol also dissolves plastic. Using a plastic bag as a lid is idiotic.

I need it for my lawnmower.

I feel like there was a stage between Upon learning this and I completely lost my rag where you could have explained how dangerous it is and that you were going to buy a new can.

Weird to keep it in the house though, shed/garage is the norm.

Chinny reckon aye?

Did ye aye?

You lost your rag at the stupid bint? For ordering a replacement cap? Most people keep their petrol cans in the garage or shed.

"very outing" 😂

I did initially explain how dangerous I think it is and I suggested to store it outside instead. That is when she she brought up her concern/theory that a person could enter our garden, find the petrol, and put our house on fire, and she said it was much safer to keep it in the house and she would not accept for it to be placed outdoors behind the outbuilding. She also refused to tell me where in our home she had placed the broken and full petrol can.

That is when I lost my rag. I personally think there is virtually no chance of an intruder finding our lawnmower petrol and lighting up our house. However, I do think there would have been a small but unacceptable risk of ignition of petrol vapours in an enclosed space from a defective petrol can somewhere in our house. I therefore brought up the hotel idea/threat partly out of anger, and partly to say, in effect, that there was just no way I was going to accept that my daughter and I sleep even one night in a house with a full petrol can that has a broken cap.

Instead, I was going to try to buy a new petrol can, and then if she still would not tell me where the broken can was so that I could remove the petrol or change the cap, we were going to a hotel.

I still find it incomprehensible that she thought it was OK to fill a broken petrol can and store it in the house. She had so many other options: wait for the new cap before filling the can, or buy a new can herself, or at the very least store the can outside if she did not want to make an extra trip or buy a new petrol can.

In any event, the practical problem is solved now, because we have a new can, and I have also placed it inside the outbuilding, which is my home office, which is locked, because I prefer not to have a full petrol can in the house even if it is fully intact.

My AIBU question is in effect, should I have just accepted for the full petrol can with the broken cap to remain inside inside the house for a night or two, and also, was it unreasonable for me to have become angry about this?
