Chemical Hazards & Safety Data Sheet Training
CHCS offers Modular Training Courses on the writing of Safety Data Sheets (SDSs), and related issues such as classification, labelling and other documentation.
About The Course
These Modules are specially prepared for CHCS, and given by acknowledged experts in their fields. The course has been designed with 4 conceptual levels incorporating basic introduction, core knowledge, interpretation and use of knowledge. It is split into several Modules as shown below.
Our training courses are only available to CHCS members, unless you book an "in-house" version (see below). If you aren't a member of CHCS we'd be pleased to welcome you to the Society, and then you may register for our training courses (and other CHCS member-only events). You can JOIN US by completing the form on this website.

In-House Training
If you have several people, in your organisation, that you would like to attend one or more of our Modules, it may be worth considering arranging an “in-house” course. We run these just in the same way as our normal modules, but just for your own personnel. We can run any of the modules listed as “in-house”.
If you wish to find out more about “in-house” training options, please contact the CHCS Office (enquiries@chcs.org.uk).

Modules 5 & 11, 6 & 12, 8 & 10, 53 & 20 are normally offered as 'pairs' (presented in consecutive weeks, each module itself on two consecutive mornings). Delegates can nonetheless choose to attend an individual Module from any of those pairs.

Module 3 Introduction to European and UK Chemical Regulation
Module 5 Basic Toxicology
Module 6 Basic Ecotoxicology
