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.

So, if you’re stuck, or need a bit of advice, get in touch by e-mail or 'phone and we'll do our best to help!

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.
