The course, which can be completed in just 25 minutes, covers key areas surrounding the Control of Substances Hazardous to Health Regulations , including recognising symbols of the Globally Harmonized System.
Additionally, we offer a Fire Awareness Training course that is also designed for all levels of employees. In the UK, it is a legal requirement to provide staff with fire safety training, and it is essential that staff receive a solid understanding of what to do in the event of a fire and how they can best prevent fires from occurring in the first place.

Flammable and combustible materials differ based on the temperatures they must be exposed to in order to catch fire. Specifically, flammables will ignite at lower temperatures than combustibles when exposed to an ignition source. This specific temperature, also known as a flash point , is what separates flammables and combustibles. The flash point is the lowest temperature at which hazardous materials will generate vapours and ignite if exposed to an ignition source.
These temperatures vary from material to material, but there are certain flash point thresholds that separate flammables from combustibles. Flammable and combustible materials will generate vapours when exposed to a temperature at, or above, its flash point, which can easily ignite when exposed to an ignition source.
Therefore, the lower the flash point of a material, the higher the risk is. This is because the temperature of most workplaces will not be above the lowest combustible flash point Oppositely, flammables are more likely to form vapours in normal work environments, because their flash points are lower. Otherwise, you will leave your workplace susceptible to a fire or even an explosion. Our DSEAR Training provides you with a full introduction to the requirements of the regulations and will ensure you understand the risks from dangerous substances and explosive atmospheres, know how to carry out a risk assessment, and can implement suitable workplace control measures.
Otherwise, the fire safety of your building could be compromised. Certain materials will require stricter controls than others to minimise these fire risks, especially depending on their flash point. Therefore, the first step you should take is to check the safety data sheets SDSs of every hazardous substance you store on site.
The law requires all hazardous materials to come with safety data sheets. A material's flammable or explosive limits also relate to its fire and explosion hazards.
These limits give the range between the lowest and highest concentrations of vapour in air that will burn or explode. This means that gasoline can be ignited when it is in the air at levels between 1.
A concentration of gasoline vapour in air below 1. Gasoline vapour levels above 7. Flammable limits, like flashpoints however, are intended as guides not as fine lines between safe and unsafe. A material's autoignition or ignition temperature is the temperature at which a material self-ignites without any obvious sources of ignition, such as a spark or flame.
Some have very low autoignition temperatures. Serious accidents have resulted when solvent-evaporating ovens were heated to temperatures above the autoignition temperature of the solvents used. Autoignition temperatures, however, are intended as guides, not as fine lines between safe and unsafe.
Use all precautions necessary. At normal room temperatures, flammable liquids can give off enough vapour to form burnable mixtures with air. As a result, they can be a serious fire hazard. Flammable liquid fires burn very fast. They also give off a lot of heat and often clouds of thick, black, toxic smoke. Combustible liquids at temperatures above their flashpoint also release enough vapour to form burnable mixtures with air.
Hot combustible liquids can be as serious a fire hazard as flammable liquids. The simplest explanation is that while flammable liquids will ignite and burn easily at normal working temperature, combustible liquids are less volatile and usually require a higher range of temperature before releasing a vapour capable of ignition.
If using, transporting or storing flammable or combustible liquids above their flash point temperature, extreme caution must be exercised to prevent ignition. The vapour of flammable material, particularly in poorly ventilated areas, is prone to ignition at standard working temperatures. Similarly, combustible liquids release a flammable vapour when in environments above their flashpoint temperature.
Vapours of both flammable and combustible liquids are virtually invisible. Being a gas, flammable vapours can escape from any open liquid source. Flammable liquid can be easily absorbed into other materials, releasing flammable vapours into the air even after the flammable liquids have been cleaned up. Flammable and combustible vapours are often more dense than air. They can quickly spread long distances and build up in low areas. If ignited, a flashback can occur, where the fire travels along the vapour fumes to the liquid source.
If an ignition source is present spray mists of both flammable and combustible material will ignite. Both combustible and flammable liquid fires tend to burn extremely fast and hot, releasing dense clouds of toxic smoke. Flammable and combustible liquids present significant fire dangers and in turn present health hazards such as burns and intoxication. If the vapours or the liquid of either flammable or combustible substances combine with other incompatible substances , they will react dangerously.
As flammable liquids pose significant risks upon the people, property and environment of your organisation, its very important that you store and manage them in a safe and compliant manner. The Australian Standard that outlines the requirements for the storage and handling of flammable and combustible liquids is AS A couple of key points that must be considered when storing flammable and combustible liquids include;.
