Re: How do I describe what I do?

Thanks Remlap12 for the information on the update. It helps us all to know that there is this information available. Now if only the administrations we work for would take this information on board and use the updated classification designations for our job descriptions.

Re: Gloves

Has anyone tried Bunnings for disposable nitrile gloves? I have a box of 75, Hercules brand, supposedly extra strong, chemical safe and latex free. I have them tucked away in the compactus so that the teachers don't use them for general distribution. I have normal disposable gloves for general class...

Re: How do I describe what I do?

Please google the following: School science laboratory technicians national standards for professional practice 2014. This document will give you an outline of what it is that we do in our jobs. Just adapt it to your own situation.

Re: Chemwatch

I have Chem Supply listed in my favorites section and just download when I need to update an SDS for a chemical. I don't have to logon to the site. If they don't have an SDS for any obscure chemical that I might still have on my shelf I then do the Google thing.

Re: Silver powder recovered from metal displacement reaction

Are you planning for your retirement? Sorry about that - last day of term. You could try using a carbon block and a Bunsen blue flame. We had a piece of equipment (a type of tube - blowpipe) which enabled the user to make the flame to burn hotter to melt various metal powders, but we haven't done th...

Re: Potassium Iodide

Potassium iodide of any strength 1M or 2M, will eventually turn yellow in its container, usually pale yellow. That colour change happens after a long period of time. Even my 0.1M solution has a faint hint of colour but it has been sitting on the shelf for a long time. So I may have to make up a fres...

Re: blood- splatter and skin safe

Google - FSB06 blood spatter. Hopefully it will give a site (FSB blood spatter) that has a number of blood spatter recipes (Forensic Investigations) you can work with. But you have to make sure that the 06 is included in the search.

Re: Cleaning carbon rods

Try steel wool. Any way you clean them will be messy. If the copper deposit is extremely stuck on then perhaps remove it by scraping with a single edge blade or a Stanley knife and then use the steel wool.

Let me know if the guidelines I sent were of any use. Feedback is always useful if it wasn't fit for the purpose that you needed assistance with.

We have a booklet "Science Guidelines September 2009". It was put together for the public school system but all high schools were expected to follow the guidelines. It covers a variety of things including dissections, animal ethics etc. I can't find it online at the moment but I may be able to send ...

Google - 2014 school science laboratory technicians standards. This document is worth a read. It will give an idea of what you should possibly be classified as and what type of requirements are needed for each classification. Don't hold your breath though if you expect any changes. After 39 years I ...

Re: Hazardous Chemical Register

I get most of my SDS from the ChemSupply website. It is quick and easy and most of my chemicals are sourced from there by the supplier that I use. Other easy sources for SDS are ThermoFisher Scientific and Sigma-Aldrich. Also Scharlau (lots of background writing on the printouts) and ScienceLab.com ...

Re: chemical register

My chemical register is set out on excel spreadsheet. Each class of chemical is set out on different spreadsheets. So Class 3 chemicals have a separate spreadsheet to Class 8 and so on. There is also a separate spreadsheet for the no class (nc) chemicals and separate spreadsheet for indicators. I do...

I have just looked at this site and the banned chemical list that is there, and if you go to the bottom of that list (after Z) it says the list was last updated 0n the 19/2/2020. So I don't think it is dark ages stuff. Thanks for the link Mel. It will be quite useful. I've already put it on my favor...
