AIBU to be annoyed with my parents about an 'explosive risk' at nursery?

I'm a single mum working full time with a toddler, so my parents are closely involved with me & DS, and most of the time it's completely fine and they respect my decisions when it comes to raising him. The other night though when we stopped by for a cuppa on the way home from nursery, I mentioned that the messy play game for that day at nursery had been playing in flour to replicate the snow at Christmas and that DS had had a whale of a time according to the staff. I thought it was a sweet little anecdote to pass on so the sheer look of horror on my parents' faces threw me.

Dad in particular freaked me out as he's not the type to over-worry or try and wrap DS up in cotton wool but he was genuinely shocked about the 'explosion risk' from flour and said that it was dangerous for the nursery to be using it for play purposes. I know the science behind the risk of airborne fine particles causing large explosions, and have seen some horrible stories about it occurring in large-scale storage areas, but surely playing with a few 100g in a nursery is perfectly fine?! I tried to point out to him that it would be no more dangerous than me flinging some flour around when I'm baking or making dough, but he was adamant it was extremely dangerous as the babies and toddlers would be 'throwing it up in the air' lots. Mum then said I should ask for the risk assessment from the nursery. She wasn't joking either. To the point where later that evening when I was back home, she sent me an email with a link to the HSE website about explosive risk from powders in industrial settings (although she did manage to admit that the scale of flour being used was slightly different) and she knew I thought they were being 'silly' but it was a real risk.

REALLY?!?! Am I missing something here?! Have there been lots of stories about nurseries spontaneously combusting because the self-raising flour was chucked about one too many times by a small group of hell-raising babies?! I really like the nursery DS goes to. The staff are warm, friendly and I can see how much DS has come on in the few months he's been there. It's stupidly convenient for work too although this means it's not the one that's round the corner from my parents which I suspect it's why my Mum doesn't trust them (doesn't bother Dad I don't think).

They also make little comments about nursery not feeding him enough (he eats pretty much anything they give him - I'm trying to make the most of it before he gets fussy) and I'm starting to feel that they're trying to chip away at my choice of nursery for him as if my judgement in choosing it in the first place was wrong. I understand that they're concerned about DS and his wellbeing (currently their only grandchild), but it's pissed me off royally and I'm struggling to let it go, or know what to say to them to tell them to butt out when 99% of the time they're really helpful and supportive. I'm a non-confrontational type and I'm worried if I don't say something, it'll build up inside me and explode (pun intended) up into something else that might mean I say some hurtful stuff.

Parents eh?

what did the key worker say when u mentioned it op?

FuzzyWizard · 14/12/2016 16:59

This can be incredibly dangerous. I don't think it's safe. There was a massive disaster in Taiwan when a spark set of a cloud of coloured starch at the Formosa Fun Coast water park. They were having a colour party full of teenagers and young people. I remember it because it's a water park I have visited. I think a lot of people don't realise the danger but it isn't silly or laughable to alert the nursery to the potential for it to go wrong.

toomuchtooold · 14/12/2016 17:03

My anxiety I'm trying hard not to go and throw away the flour in the larder.

It's not the flour itself that's the hazard, it's when it's hanging in the air as a dust cloud - then it''s very well mixed with the air so it can burn very quickly if it catches fire. Just don't throw it about!

MsAdorabelleDearheartVonLipwig · 14/12/2016 17:20

Was a big problem in Victorian times, flour mills used to explode and kill lots of people.

rainbowstardrops · 14/12/2016 17:33

Exploding flour???!!!! Shock
Who knew?! Grin

5foot5 · 14/12/2016 17:37

When I was at uni my housemates were forever blowing up Roses tins full of flour in the yard. However it seemed to take mostbof the day, about 100 attempts and several boxes of matches to produce a tiny explosion.

Oh I always wanted to try that. I had a book by Magnus Pyke when I was a child that described how to do it. As I recall you really didn't need to use very much flour but you had to have a candle in the tin with the flour and then blew through a tube so that the flour went up in to a cloud.

I think there was a pretty horrific explosion in a Taiwanese night club last year when some powder exploded.

DearMrDilkington · 14/12/2016 17:48
Shock

I always have candles lit when I bake in the kitchen and I usually get flour everywhere! I won't be doing that anymore!!

DearMrDilkington · 14/12/2016 17:49

Is there a flammable warning on flour packets? I had no idea about it.

fuckweasel · 14/12/2016 17:58

I've no idea about small quantities of flour, but there does not need to be a source of ignition such as a flame to ignite fine particles. A static electrical spark is a major cause of ignition in flour explosions and can be built up by the movement of the flour particles themselves.

PinkSwimGoggles · 14/12/2016 17:59

an electrical spark is an open flame.
just like sparks from grinding millstones...

EstelleRoberts · 14/12/2016 18:06

When I was at uni a guy emptied bags of flour at the top of a staircase, ran downstairs, and lit it. The resulting explosion blew the skylight clean out of the ceiling....

Airborne particles are very combustible, but only if you light them. Presumably there wouldn't have been a lighter or matches in the nursery, though.

fuckweasel · 14/12/2016 18:13

Depends how you define a flame. A flame is generally though of as being produced by an exothermic chemical reaction. A static electrical spark is a flow of electrical current across an air gap. .

MrsMattBomer · 14/12/2016 18:20

I'm proud ashamed to admit we've done the flour in chocolate tins thing with the kids. It's irritatingly fun.

But yeah, you generally need a heat source for something to combust.

EagleIsland · 14/12/2016 18:26

Coffee mate is very similar in the tin if you don't have flour

insancerre · 14/12/2016 18:43

I have heard this before
It was mentioned on a nursery managers forum I am in
Everyone laughed at her as well

WonderMike · 14/12/2016 19:02

This is a thing - EHS background here, dust explosions are fairly easy to cause in a lab with the correct material and a source of ignition - which could just be a small spark.

But that's the hazard assessment - the likelihood of that event occurring is the risk and the risk assessment should point out the hazard and the steps taken to mitigate and reduce the chance of the hazard occurring.

So the fine particles cause the dust cloud - you use 'clumpy' flour or a powder that is has a low dust explosibility I can't believe I've forgotten the term You remove sources of ignition and sparks etc etc

OopsDearyMe · 14/12/2016 19:20

I think in our day and age, with the nonsense health and safety lot expecting kids to wear goggles to play conkers, that the nursery would have done its checks here lol. Sounds to me like the classic.
Mum is annoyed coz daughter is doing things differently to her, mum thinks she knows best and is irked.
I am guessing that she was a stay at home mum, mine too! Mins sees any parenting choice that I make that is different to hers as a judgement on her. Tbh it is, we all want to avoid the things we had growing up that were not positive for us. That however can say to our mums that they did a bad job. Even if we didn't mean that.

I am shocked however at the flour causing an explosion thing being such a big deal lol. Must date back to some old wives tale.

Wookiecookies · 14/12/2016 19:54

Okay so knew about flour being explosive (great fire of london). However, pistachios?

Wtf? Please tell us more! so I can remove the terrifying little green nuts from the house without looking totally bonkers

clarr · 14/12/2016 21:23

think you should ask for an elf 'n safety appraisal for all future play activities.. .

GrinGrinXmas Grin

I laughed at that way more than is healthy!

dylsmimi · 15/12/2016 04:41

Were the children really throwing it about though? I know it's messy okay but that tends to involve hands etc getting messy not the whole of the nursery. I would assume t was in a tray for children to trace patterns or play with like sand and the same 'no throwing' rule applying. This might reassure your parents
I didn't know about exploding flour either - mumsnet is a source of information

seven201 · 15/12/2016 04:54

Haha! Your parents are bonkers. I'd be more worried about flour getting in their lungs than exploding! Not that I'd worry about that either. I think this is one you just need to ignore. If they continue with the nursery criticism you need to sit them down and tell them to stop.

insancerre · 15/12/2016 07:19

*Dylis

When we have flour in the nursery it is on the table for sensory pay
We don't throw it around and we don't have huge amounts either
It's just that a little goes a long way Grin

dylsmimi · 15/12/2016 08:33

Very true insancerre I just had a thought that perhaps ops parents thought the children were having a full on flour/snowball fight with it and clouds and clouds were everywhere when it was probably more low key with a bit less clouds of flour (hopefully!)
