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..
Asbestos found in ceramic gauzes
CLEAPSS has been working with the DfE and HSE around the supply of gauzes which contain Asbestos. 

The HSE released this press release about the issue.

The Dept. of Education have released a letter to Headteachers in schools and Principals in FE Colleges. CLEAPSS recommends sharing the appropriate letter with your HoD and Headteacher / Principal.  

Customers of each company involved will receive communications from them the issue. We are not in a position to name these 

Please do NOT call us about this issue unless you have read the latest version of all three of the below documents. (GL286, Full HSE Press release and the HSE Guidance document). 
If after reading all three of these documents, and you have discussed the issue with your HoD & Headteacher you still have questions, then of course feel free to call the Helpline.

We have created a FAQs guide (GL286) to assist schools with this issue. This guide is designed to be read in conjunction with guidance from the HSE and the full HSE press release

We have also produced a gauzes buying guide GL285

Worried you don't have any gauzes you can use, but want to do the classic 'heating water' practical with your Yr 7's? Then use our new guide PP055 heating water, which is totally gauze free!!!

New Edition of CLEAPSS Guide L093 - Radioactives in Schools
We have issued a new edition of L093. See Guide GL114 for a list of the changes and what you need to do. 

The main reason for the new edition was the change in the Ionising Radiations Regulations which we explained in our termly bulletins and web site earlier this year.  

If your school holds the typical radioactive sources for teaching, your employer must register the work with the Health and Safety Executive. (See guide GL258.)

However, we have also been reviewing ageing sources that schools have acquired in the past. There is convincing evidence that using Becquerel plates and radium-painted timepieces of this age can no longer be justified. 

The condition has degraded to such an extent that they can no longer be regarded as safe to use. These need to be disposed of L93 gives details of disposal.
