Learn the basics of writing a Safety Data Sheet

These two days are aimed at those who need to prepare or evaluate SDs for mixtures using data from incoming (extended) SDS or from other sources of information. Supplier SDS may not always give all the information needed and, in all cases, it is necessary to interpret all available information as efficiently and as effectively as possible.

Even where supplier SDS are reliable, the act of mixing substances with different properties will lead to questions over suitability of exposure reduction methods (e.g. glove types) and also raise questions for appropriate first aid or cleaning of spills. Understanding the properties of ingredients and the nature of the mixtures prepared is key to minimising risk to users and in meeting regulatory compliance.

Day 1 of the course is designed for anyone who is involved in writing safety data sheets with particular focus on mixtures.

Topics covered include:

  • Evaluation of information from supplier's SDS, especially if importing
  • Use of public databases to enhance confidence in supplier data; how much effort is necessary?
  • How to use information from suppliers and other sources to prepare your SDS.
  • The issues of interpreting mixture data for toxicology and ecological sections and its impact on other sections of the SDS.
  • The use of classification and data estimation for mixtures and how the use of software compared to real estimates can give different answers.
  • How an understanding of basic physicochemical data can be used to address other sections of the SDS (e.g. exposure routes, accidental spillage and clean-up methods, etc).
  • Important considerations when writing first aid measures.
  • Risk management measures (specifically considerations when recommending appropriate personal protective equipment, the use of engineering measures, etc – could be on day 2)

Throughout the day the use of real-life examples and set exercises will be used to enable the participants to put their new-found knowledge into practice.

Day 2 will cover exposure reduction and, where available, the interpretation of the supplier's exposure scenario

Topics covered include:

  • An overview of the regulatory requirements; what 'appropriate' information needs to be supplied onwards to the recipient.
  • What is exposure reduction through use of controls and personal protection
  • How can we apply these to industrial, professional and consumer uses
  • The relevance of substance DNELs, PNECs and their use in assessing mixtures
  • Understanding how the Exposure Scenario is prepared and the use of default data and guidance; is the Exposure Scenario relevant for your mixture
  • Manual estimates and use of models (EUSES / ECETOC / Chesar )
  • Exposure estimates (workplace exposure – industrial and professional and also exposure to the general public including secondary exposures via food and water)
  • Scaling factors and adapting information for specific sites and uses
  • Expected outcome of the communication to recipients

Throughout the day the use of real-life examples and set exercises will be used to enable the participants to put their new-found knowledge into practice.
