Storing radioactive rocks can be easy if you know how 'hot' they are. For example a granite kitchen bench is radioactive also. So you need to consider if you are reading the levels appropriately. Like above I would read through the arpransa doc and also contact them if unsure. Low level radiation di...

How often should the safety showers be checked? We only have the little hand held eye washers so I change the water in those weekly. We had some of those handheld bottles that needed water refills...I have ditched them and purchased 1L saline bottles for the labs with an eyewash attachment on them....

We use morning fresh on our gas syringes...just a little. Works a treat, better than having Vaseline or silicon grease all over them.

Good job mtg, it's amazing how fast those delivery charges add up

We'll have to try this

We use these ones, haven't had any issues with them. Often though we tell them to leave the hot gear and we duck in between classes and put away.

Distillation will feature next year in Senior Chem, study change happening

I have removed every tiny bit of mercury from the school, even some old thermometers we had. No longer needed in my opinion in a school

We have dried egg on ours !!! eggs exploding after being forgotten about boiling. Left it there for the memories.

sad face...... what happened to the lovely lime coloured box

We've made safety glasses a personal item for our older kids no more cleaning glasses after each use for us. Love it.

Oh no, what next

Just pop it in a big tray with a drop sheet under. Good to go, no stain

Thank goodness all our chairs have metal legs. Can't believe the kids do this ..

Another Stile whinge. Yesterday I spent about two hours prepping for a Stile prac. I think I should be treating these like prac tests - every class does it, to justify the effort and I need two weeks notice! Today's request - 1kg flour and 100g of cocoa so the kiddies can drop marbles from a height...

@Merilyn1 awesome info, thanks

I got some 200 boxes from Winc (stationery supplier) recently. Thanks, I'll check it out Just a heads up... A shipment of our Westlab Nitrile Gloves 200PK are expected to land in Melbourne Docks on the 13th of November [Add on a week or two for customs]. excellent...love the lime coloured box, hope...

We have disposed of all ours on site...they should have been gone 10 years ago, I keep finding stashes from the last lab techs...naughty naughty
