DSEAR is about minimising risk. The responsibility for achieving this is given to employers - but employees also have a role to play. In this section, users will take a look at these steps in more detail, including what employers must do and what it means for employees.

Dangerous substance safety essentials

In our final section, we look at employee responsibilities. DSEAR doesn’t place any specific legal duties on employees, but they do still have certain responsibilities, including taking reasonable care of their own health and safety and that of anyone else who might be affected by their work.

About this course

The Dangerous Substances and Explosive Atmospheres Regulations were introduced to make workplaces safer for anyone who works with flammable or potentially explosive substances or substances corrosive to metal.

Without proper controls in place, these substances can ignite and explode, causing serious harm to anyone nearby.

DSEAR places responsibilities on employers to keep anyone who might be affected by dangerous substances safe and to control any hazards they pose. However, employees also have a crucial role to play in keeping themselves and others safe at work.

This course teaches the user about DSEAR and what it covers, what responsibilities employers have to keep everyone safe, and what employees must do to help their organisation comply with the regulations.

Useful course

interesting course

very informative And interesting course

good to feel safe.

Brief but gets the main points across

I would like to have seen more information about ATEX equipment and sources of ignition examples, such as static, mobile phones etc. Overall, it gives a good foundation for DSEAR Awareness

very interesting

eye opening to the dangers of all materials...

A reasonable overview of DSEAR

I have awarded it 4 stars as I believe it was a good introduction as to what DSEAR is and reasons for managing it etc. However I was looking for a slightly more in depth presentation at a more technical level covering inspection methods, criteria, safety labels based on use of Natural Gas.

Could be better

A few of the questions were repeated with different answers, one of the answers were wrong

Why is this training important?


It's important that you comply with the law and know the ways in which it affects you and the way you work.

Compliance with The Dangerous Substances and Explosive Atmospheres Regulations 2002 is a legal requirement in the UK, and failure to do so can lead to organisations and individuals being fined and prosecuted.

DSEAR applies to workplaces where dangerous substances are present, used, or produced.

Workplaces are any premises or parts of premises used for work. This includes places such as industrial and commercial premises, land-based and offshore installations, mines and quarries, construction sites, vehicles and vessels, etc. Places such as the common parts of shared buildings, private roads and paths on industrial estates and road works on public roads are also premises – as are houses and other domestic premises, if people are at work there.


Business benefits

It is crucial for all organisations to carefully consider how they can best keep everybody safe.

Knowing what substances in your workplace have the potential to present fire and explosion risk should be a key part of an organisation's risk assessment. If there are any substances of this nature present, then it is crucial that relevant personnel are provided with training to understand the dangers associated with the substances and how to avoid any accidents from occurring.
