CLEAPSS Supporting practical science and technology
Welcome to the new CLEAPSS Science Website
What is CLEAPSS
CLEAPSS resources give teachers ideas for exciting and engaging practical activities that fire pupils' imaginations and then, unlike many other sources of ideas, go on to show teachers and technicians in detail how to translate the ideas into safe and exciting experiences in the classroom.
CLEAPSS advice and documentation is recognised by the Health and Safety Executive and the Department for Education.. (read more)

End of Term - Lab Checks
The end 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.
