Explosion risk with surfboard manufacturing
Gday guys
Im currently helping design an explosion proof door for a coal hopper.
for those that dont know, many dusts such as flour, aluminium, cheasecake mix to resin and dog buiscuit powder can explode when the oxygen to particle ratio is high enough, and the particle is of sufficient smallness, and a source of ignittion (such as a spark, static electricity etc)
I noticed that on the list of hazard rating of dust types,
Polyurethane foam 0-80 Weak to Strong
Resin >80 Severe
does anyone in surfboard manufacturing take into account the possible explosing risks of surfboard dust mixes with compressed air?

Re: expolsion risk with surfboard manufacturing
often wonder what I am breathing in when I have a batch of fresh boards in the wagon, I know I get headaches from it sometimes...usually have the windows open to flush out the fumes but when its raining, it is friggin nasty....
Re: expolsion risk with surfboard manufacturing
mark what you are getting there is a styrene mekp mix and if you are getting headaches from it your to close

Re: expolsion risk with surfboard manufacturing
yeah, thought so ( i know its styrene but dunno the mekp bit ) but gotta get em from A to B...maybe a mask while I drive ...coppers will like that ...
cheers

Re: expolsion risk with surfboard manufacturing
that would look awesome mark, in the car with you gas mask on, lol, yup I can imagine what the cops would think.

Especially if some cop still has an outdated report showing your car as stolen.............. >><<diggerdickson wrote:that would look awesome mark, in the car with you gas mask on, lol, yup I can imagine what the cops would think.

You aren’t the room Yuke You are just a wonky cafe table with a missing rubber pad on the end of one leg.

I still don't buy the "official" narrative about 9/11. Oh sure, it happened, fcuk yeah. But who and why and how I'm, not convinced it was what we've been told.

yeah, combine that with tattoos and current mohawk, I must be a criminal....
Re: expolsion risk with surfboard manufacturing
guys i wasnt meaning the chemical explosion you get with styrene, thinners, catalysts etc.
im talking about dust explosions.
if you get a flour silo, and the right air -particle ratio, and a spark, caboom.
same with most fine dusts.
they rate styrene resin dust as severe, however ive never heard of a styrene dust explosion

Re: expolsion risk with surfboard manufacturing
marcus the concentration of sanding (ex-resin) dust in a typical surfboard factory just isn't massive enough to create the conditions you're talking about.
Foam dust from shaping, a) the particles are too big and b) most surfboard blank cutting these days happens in cnc machine shops where dust is cleared away on a constant basis.

I thought that was caused by the carbos and friction in the air causing static and all.marcus wrote:guys i wasnt meaning the chemical explosion you get with styrene, thinners, catalysts etc.

my boss chucked a scrumped up oily kero rag think it was,
in the corner of the garage and it self ignited and set the house on fire, got a new kitchen.

Re: expolsion risk with surfboard manufacturing
nah anything that can burn ca explode in the right conditions, thats one reason some dusts are pnumatically conveyed (blown through pipes) with carbon dioxide, also good with food powders. link under my first post explains it all.Quangers wrote:I thought that was caused by the carbos and friction in the air causing static and all.marcus wrote:guys i wasnt meaning the chemical explosion you get with styrene, thinners, catalysts etc.

yep,.sorry your right, any spark, incluing friction caused staticdaryl wrote:could still include friction, no?marcus wrote:nah anything that can burn ca explode in the right conditions, thats one reason some dusts are pnumatically conveyed (blown through pipes) with carbon dioxide, also good with food powders. link under my first post explains it all.Quangers wrote:I thought that was caused by the carbos and friction in the air causing static and all.marcus wrote:guys i wasnt meaning the chemical explosion you get with styrene, thinners, catalysts etc.
