CLEAPSS Supporting practical science and technology
CLEAPSS Chemistry
Chemistry – Let's make it happen!

CLEAPSS provides guidance for teachers, technicians, science advisers and H&S officers on all aspects of practical work. We know that chemistry experiments can cause problems and activities may not 'work' as expected, or provide the effective learning opportunity that’s required. Sometimes, health and safety concerns are raised about the chemicals involved.

CLEAPSS works with suppliers and others to ensure that suitable chemicals and equipment are used in schools and we can also suggest ideas and innovative methods that might help you enhance practical chemistry in your school.

Latest news from CLEAPSS..
Hot weather - check your chemicals
As temperatures rise, remember to keep an eye on your chemicals and respond appropriately if you notice any problems. See GL246, GL247 and GL252 for advice on doing this safely. 

However, further to our recent Bulletin article, some schools have asked us about bottles of chemicals from different suppliers. Some of these are fine – they may be a different type of plastic which is more durable with whichever chemical they contain. If in doubt, contact your supplier or the CLEAPSS Helpline.
CLEAPSS Websites - www.cleapss.org.uk
Our regular visitors may have noticed that our website was hacked late on Thursday afternoon which resulted in users getting an 'account suspended' page. Unfortunately we have so far been unable to recover the website so we have installed a new home page to replace the legacy site. We are currently working on reinstating some functionality, in particular the technicians job service, so please bear with us.

It seems it's a big bad world out there so please accept our apologies while we repair the damage.

Regards from the CLEAPSS IT team.
Student Safety Sheets - 2018 CLP Edition
The 2018 CLP Edition of Student Safety Sheets are now live on our website. 

They have been fully reviewed and revised taking into account changes due to CLP and feedback on the use of the sheets in schools.

Find all the sheets here and the teachers guide here.
HSE Radioactive Sources Registration
Since 6 February this year, employers who have employees using radioactive sources must notify, register or obtain consent from the HSE before working with the sources. 

This includes schools. Some school employers don't realise that the small teaching sources used in school science fall into the registration category. If you are not sure if your employer has registered the use of your sources, it would be sensible to check. Our advice is that the employer should get the registration undertaken promptly, even if late. 

The HSE have indicated that they are not minded to take action on late registrations at the moment. We have produced a guide, GL258, which takes you through the registration process. 
We advise employers use this guide because some of the registration questions are not straightforward.
