CLEAPSS Supporting practical science and technology
CLEAPSS Physics
Physics – Let's get it working!

CLEAPSS provides advice for teachers, technicians, science advisers and H&S officers on all aspects of physics practical work - We know that physics experiments can be tricky to set up and get working. If you’re stuck get in touch by e-mail or 'phone and we can help! We also have suggestions for low cost 'make it yourself' equipment – recent examples include, a Planck’s constant LED array and a mobile phone spectrometer/microscope.

CLEAPSS also works with science equipment suppliers to ensure that their products are safe and suited to the physics classroom.

Start of Term - Lab Checks
The start of term 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.
Are you a new technician?
Welcome to the CLEAPSS science website. You can find specific resources by adding a key word to the search box. Chemicals can be searched by formula as well as by name.

Our guide for the induction and training of new technicians can be found here.
You can find our guide for model risk assessments for laboratory technician activities here

For further advice you can email the Helpline via the tab on the website or if more urgent call on 01895 251496.

Disposal of radioactive sources - updated guidance
We have revised our guidance GL220 on how to dispose of small waste sealed sources by grouting them and putting them into the dustbin. We are aware that there are several mechanical and biological treatment (MBT) plants in the UK that treat the household waste to reduce the amount going to landfill and incineration. We have discussed this with the environment agency’s radioactive substances regulators and modified our procedure. We now advise that small sealed sources are first encapsulated in epoxy resin, then into mortar, in a plastic unlikely to be recycled.  This should ensure small metal items go to incineration or landfill.
