Issues with bottles of concentrated nitric acid5 Oct 2017
We have received a number of Helpline queries recently involved plastic bottles containing concentrated nitric acid which appear to be leaking and/or releasing corrosive/toxic fumes. 

We urge all schools to check their stocks of all corrosive chemicals.

To help support schools with this issue, we have created a suite of new guides and resources. 

Guide GL246 explains how to safely check your chemicals. 

Guide E233 helps you manage you stocks of chemicals.

GL247 discusses the issues around the shelf-life of chemicals

Guide GL251 is a step-by-step guide on how to decant nitric acid, and is supported by a video.

Guide GL252 provides guidance on what type of bottle and caps to use to store nitric acid.

Bogus emails from CLEAPSS3 Oct 2017
We have been receiving reports of malicious emails allegedly coming from CLEAPSS. 

These encourage the recipient to follow a link, usually purporting to be to an unpaid invoice. 

Having investigated these, we can confirm that these e-mails are NOT coming from CLEAPSS.

Please check any e-mail that appears to be from CLEAPSS carefully.

It is important not to follow any link or open any attachment.
