About Chemdata

Accessed via an app on your laptop or desktop, mobile data terminals (MDTs), command and control systems, tablets and mobile phones, it contains over 62,000 substance data sheet (SDS) records including pure chemical substances, trade name substances, biological and radiological hazards for current and expired products. Trusted by Hazmat responders and fire and rescue services around the world, it provides instant access to chemical information when you need it most.

The powerful search function finds chemical or trade names, abbreviations, part names, UN numbers, CAS or EC numbers to provide invaluable and timely advice in the event of chemical spillages, fires, and contamination incidents. Chemdata provides information in non-technical language so that users can easily understand how to keep themselves and others safe while dealing with an incident, enabling them to resolve the situation as quickly and efficiently as possible. Users are provided with proportional advice, precautions and decontamination information, even for very small spills of less than 1 litre. For users in Australia and New Zealand, HAG codes, developed in conjunction with and used by the local Emergency Services, are also provided to aid communications.

Used by government bodies; fire, police, and ambulance services, airports, ports, and harbours around the world, Chemdata is a trusted source of information which has been designed and is continuously maintained by emergency responders from one of the world's leading chemical emergency centres.

The database tool is fully downloaded onto your device, meaning all content is accessible whether you are online or offline, and includes a comprehensive help facility within the software. It also comes with multiple language options, platform integrations and access, and the ability to add notes. The flexibility of Chemdata enables users to incorporate procedures and personal experiences and share these throughout their organisation. 

Chemdata benefits
  • Helps identify chemicals, trade name products and their hazards providing emergency responders with essential information for their immediate needs.
  • Saves time: Chemdata is quick and easy to understand and use, meaning critical and proportional advice can be found quickly and efficiently, reducing the time spent dealing with the incident.
  • Saves costs: a proportionate response to an incident may result in lower personal protective equipment (PPE) and incident impact costs, 
  • Provides advice on appropriate actions to take to mitigate an incident.
  • Up to four levels of proportional advice for different spill sizes allowing responders to make a proportionate response.
  • Offline accessibility – because Chemdata is installed on your device it can still be used if there is no internet access.

Chemdata is also a useful reference tool for carrying out risk assessments for COMAH and COSHH and understanding transport of dangerous goods hazard classifications.
