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.  We try to keep the ocuments updated on a regular basis.

Denehurst is located in the North of England in the town of Ilkley; 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.

UK-REACH and UK-CLP start from 1 January 2021.  

Although the scientific basis and data assessment requirements for the UK systems are aligned initially to the EU and GHS, there will be a need to duplicate many of the administration processes of REACH Registration and providing of labelling and SDS. 


Poison Centres

All EU Member States (except the UK) had established national poison centre rules as part of CLP before 2020, but from 2021, it will be possible to make a single on-line notification through ECHA to cover (most) Member State requirements. The UK will not be part of this process and UK-based legal entities will not be able to make formal Poison centre Notifications (unless based in Northern Ireland)

Public training events

Animal testing policy

Details of Denehurst policy on animal testing can be found here

Denehurst offers free support and advice to any organisation worried that animal testing proposed by co-registrants for REACH or implied by ECHA are not needed.

ECHA cannot legally demand animal tests and the REACH Regulation makes it clear that all attempts to avoid animal work must be avoided.  ECHA and UK HSE can quite rightly demand data quality improvements where there is a lack of evidence to support earlier non-animal test data (or re-across/grouping), but only if there is no scientifically valid alternative should animal work be considered.
