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.

Check your 2,4-DNP2 Nov 2016
Schools who hold stocks of 2,4-DNP (2,4-dinitrophenylhydrazine, technically called 2,4-DNPH) are reminded to check the storage arrangements for this chemical are as per Hazcard 30

If it has been stored as advised, or is unopened as supplied (as it contains water for supply) there is no cause for concern. 

However if there is no water in the outer container or the reagent bottle has not been placed inside an additional container you must assume that the material has dried out meaning that an additional risk is present.

Do NOT open the reagent bottle.

Please do not call the police.

Instead please call the CLEAPSS Helpline for further advice.

Laser Cutting Equipment12 Jan 2017
It has been brought to our attention that there are a number of pieces of laser cutting and engraving equipment available online that do not comply with national guidance and/or regulations. 

In these machines the laser is not enclosed creating an increased risk of burning or eye damage.

CLEAPSS Model Risk Assessment 1.032 Laser Cutters states that the laser beam should be totally enclosed and an interlock provided to prevent operation unless the laser is enclosed. This is necessary to make the system into a Class 1 device, which is then suitable for use in schools.

If you have purchased a machine where the laser is not enclosed you should stop using it immediately.

For further advice and guidance please contact CLEAPSS.
Thefts from chemical stores in schools in the Kent area4 Jan 2017
CLEAPSS has become aware of a series of break-ins to chemical stores in schools in Kent. In each case the thieves have targeted very specific chemicals. If your school is in Kent and you have suffered a similar break in recently we would ask you to let us know what was stolen as this will help us assist the police in determining the likely reason behind the thefts. These events serve to remind us all of the importance of storing our chemicals securely. Remembering to routinely lock storage cupboards, chemical stores and prep-rooms can go a long way in ensuring that chemicals do not fall into the wrong hands.
