Denehurst Chemical Safety Ltd is an independent consulting organisation specialising in chemical supply legislation and aims to help industry help itself through training, mentoring and general support.   Denehurst was set up by Mark Selby in 2000.  Gill Pagliuca joined Denehurst in June 2009 and added a new dimension with experience in GHS and Transport classification.  

Denehurst can help with chemical supply legislation through offering advice, taking action or providing training.  This includes work with new and existing substances, CoRAP and Registration Quality issues, or checking data for compliance or value.  

Some of the Guidance documents prepared by Denehurst are offered on this site and these give an indication of the type of area we work in.   However, more information can be provided on request.  The documents are updated on a regular basis.

Denehurst is located in the North of England in the village of Burley in Wharfedale; less than 10 km from Leeds / Bradford International Airport and close to the UK motorway and rail networks.  Gill is based near Oxford and can provide local support in the area as well as easy access through the London airports for less local support.
Local links 
are important and if curious about the North of England, have a look through the community web-sites  as it is more fun than working.

Brexit, REACH and CLP

It’s early days and there are still a lot of questions without answers.  Here, we try to answer some of the initial questions you may have


CLP for mixtures

The deadline for new labelling was June 2015, but there is still time until June 2017 for products in the supply chain to be used and supplied onwards with the old labelling. 


Updating SDS   

New data from REACH registrations will filter down the supply line and will also be published as disseminated dossiers.  SDS must be updated with 'significant' new information 'as soon as possible'


Extended SDS 

Substances that have been registered and have a Chemical Safety Report, need to include the Exposure Scenarios from the CSR as an annex



The Community Rollin Action Plan is a process where substances considered to be of 'interest' (high exposure, concerns over toxicity or for the environment) are reviewed thoroughly by Member State experts.  


At this stage, science is  important; Denehurst is supporting a number of substance reviews
