Module 1: Controlling fire and explosion risks in the workplace
Watch the below video to identify workplace fire and explosion risks control and mitigation measures then study the text in this page and the following
pages and refer to sources of information recommended in the module then assess your understanding by solving the end of module quiz
Dangerous substances such as solvents, paints, varnishes, flammable gases, liquefied petroleum gas (LPG), dusts from machining and sanding operations, and
dusts from foodstuffs can be found in nearly all workplaces and could, if not properly controlled, cause harm to people as a result of a fire, explosion or
similar incident, such as an uncontrolled chemical reaction.
An employer must first consider eliminating or reducing the risk by replacing the dangerous substance with another substance, or using a different work process.
In practice, it is recognized this may be difficult to achieve, eg where the dangerous substance is used as a fuel. However, for some work activities and
processes it may be possible to eliminate or reduce the risk by using a non- or less dangerous substance, eg by replacing a low-flashpoint liquid with a
non-flammable liquid, or one with a higher flashpoint. Where this is not reasonably practicable, an employer should consider what control measures to take
to prevent a fire, explosion or similar energetic incident from occurring.
1.1 Control measures:
Control measures should be prioritized as follows:
Reducing the quantity of dangerous substances to a minimum.
Avoiding or minimizing releases of dangerous substances.
Controlling releases of dangerous substances at source.
Preventing the formation of an explosive atmosphere, including by ventilation.
Collecting, containing and removing any releases to a safe place.
Avoiding ignition sources.
Avoiding adverse conditions (such as exceeding pressure/temperature limits) that could lead to danger.
