Re: GHS Labeling

Annette, does that mean if we send a solid chemical into the lab for some prac that it has to have the GHS label despite Safe Work Australia saying only chemicals purchased after Jan 2017??

Re: GHS Labeling

I, too, am at an independent school and I can't access the link you have provided. I would be interested to know what the DET is saying. Many thanks.

Re: Labelling Indicators

Hmmm... Just had a look. I don't like that. I usually make them up as a percentage not a molarity. Wonder what others think.

Re: Multimeters

Interesting he says more durable?. I have the same amm/voltmeters for 10 years I've been here and haven't had may break at all but I have 6 cheap multimeters that have the ammeter broken. Maybe I should just get more of the old analogue ones.

Multimeters

Do your classes use multimeters instead of amm/voltmeters? If so where did you get them? I have now got half of mine that the ammeter no longer works on. They are between 4 and 6 years old. So frustrating. Not sure if I should replace them or not?

Thanks for replying. I thought it might be a long shot.
Hmm.. Ok I have no idea what the ones we have are. They seem like a mish mash of different kinds. I will have to check before ordering.

Just reading back through the Risk assess document and found this: It is recommended that your school obtain copies of ISO Standard 31000:2009 and the Risk Management Guidelines HB 436:2004, and that persons carrying out risk assessments be familiar with them.

Re: Risk Assess - Legal Issue with signing

Why don't you go back to Risk assess and ask them if they have a copy of the standards you can access?? They must know what they are if they are quoting them!?

Re: Chemical Store "odours"

When I first started working here our chem store was very toxic. There was a huge amount of rust on the shelves and condensation on the floors. Over the years I have replaced the shelves and the exhaust system. This resolved most of the issues with the odours. The flammables cupboard is still very f...

Re: Storing Alligator wires

I have a board about a meter long mounted on the wall that has slots sawed into it. The connecting leads hang off that. You can fit about 10 per slot. I store the alligator clips in a separate container. Works well.
