CLEAPSS Supporting practical science and technology
CLEAPSS Biology
Biology at CLEAPSS –present fascinating, future exciting!

Biology has been developing very rapidly over the last 40 years, and this is increasingly being reflected in the content of biology lessons.

To support these developments CLEAPSS has been working on a range of practicals, guidance and training courses to enable schools to meet the demands of this new curriculum in safe, engaging and innovative ways. We are also on hand to answer any queries you may have regarding Health Safety aspects of biology practical, whether new or old.

Exam Season - Lab Checks
The exam season is an ideal time to do some basic checks in your labs. Aside from the more basic checks like are the sinks clear, and do the taps work. There are more important checks to be made...

All benches / worktops / bollards which have gas taps should not allow any movement (in any direction). CLEAPSS has repeatedly found loose worktops, benches and bollards which can wobble and move considerable amounts. This can damage the supply gas pipe, which in turn could lead to a gas leak. Watch this video for an example of the issue. 

If you do discover any movement, then the gas in that lab should be turned off and the gas should not be used until repairs have been made to stop the movement. After these repairs the gas system should be checked by a Gas Safe engineer. (This is often called a tightness test)

If you do discover a gas leak in a lab then turn off the gas supply within the lab, then follow the school procedure(s) to evacuate the building and call 0800 111 999 (if you have LPG then call the supplier number, FLOGAS 03457 200100 or CALOR GAS 03457 444999). 
Remember do not use any flames, or operate any switches on or off, and do not use your mobile phone until you are outside.

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.
