Hazardous Areas & Explosive Atmospheres
Electrical Heater Application & Benefits | The portable electric fan heaters with ATEX Certification were selected by the Engineering Maintenance Manager to provide improved levels of comfort heating in workplace locations where the processing, handling and production of spices is carried out – accumulations of spice dust and improper handling of other combustible dusts in the food and beverage industry can lead to property damage, injuries and loss of life.
The MFH Portable Fan Heater is the world’s first truly portable hazardous area fan assisted heater – the EXHEAT MFH combines efficient design with simple functionality to provide a portable heating solution for use in hazardous environments where the atmosphere is classified as Zone 1/2 (IIB) or Zone 21/22 (IIIC).
In 2019, Dust Safety Science reported a dust explosion at a Dutch spice powder factory in which 3 employees were injured – in the UK, the Health & Safety Executive (HSE) have reported industrial accidents involving multiple fatalities and severe structural damage caused by explosible dusts in the food industry including processing facilities handling flour, custard powder, instant coffee, sugar, dried milk, potato powder and soup powder.
A dust cloud of any flammable material will explode where:
1 The concentration of dust in air falls within the explosive limits.
2 A source of ignition of the required energy is present
Workplace Temperatures & Productivity Levels
Professional studies and independent surveys of workplace productivity have concluded that colder temperatures diminish labour productivity – electric heaters effectively improve temperature control and heat distribution into open spaces including factories and warehouses. Portable heaters used throughout the colder months can save money, time, and reduce productivity losses.
The electric heaters can be supplied with additional ducting to enable targeted and directed control of the air flow to improve energy efficiency and maximise the heat output.

Cold weather could inflict disastrous damage to your plant and facilities this Winter – as temperatures fall the dreaded downtime danger rises.
Whatever your process, downtime costs money.
But preventative maintenance today can safeguard and protect your processes against crippling downtime, revenue and output losses. The financial costs, both direct and consequential, can be painfully calculated however the reputational damage can be immeasurable.
Since 1985 Thorne & Derrick have been specifying, designing and supplying both standard and custom Electrical Heating Equipment to overcome the Winter weather effects of icing, freezing or wind chill in industrial and hazardous area locations.
Thorne & Derrick can conduct Heat Tracing System Designs to prevent frost damage to pipework, vessels, tanks, valves, ramps, roof gutters and emergency fire escape stairs – commercially we can deliver trace heating systems from the largest UK stocks at the most competitive prices.
We stock the most complete range of standard and custom-engineered process and immersion heaters, room heaters and thermostats with IECEx and ATEX certification.
For bulk storage containers, we stock the largest range of Drum & IBC Heating Jackets for use in industrial and explosive atmospheres – we can also manufacture bespoke, removable heating jackets to almost any shape and size. Using silicone technology we provide rapid and high temperature heat-up of complex shapes and surfaces – from concept, design to the delivery of standard or bespoke heaters on the shortest lead times.
There is a causal link between economic loss from reduced labour productivity due to low ambient temperatures. Our ranges of air warming heaters provide safe space and comfort heating in factories and warehouses with explosive atmospheres – this includes portable heaters for confined spaces and temporary applications.

According to the UK Health & Safety Executive (HSE) the Control of Major Accident Hazards (COMAH) Regulations ensure that businesses: “take all necessary measures to prevent major accidents involving dangerous substances.”
These dangerous substances are broadly categorised as explosive gases, vapours or mists and combustible dusts – they are designated as potentially explosive atmospheres and the degree of risk is determined in the UK and Europe currently according to the ATEX Directive based on a categorised “Zone” approach detailed below.
Additionally, The Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR) provides a specific legal requirement to carry out a hazardous area study, and document the conclusions, in the form of such hazardous area zones.
COMAH locations must undergo classification of plant into hazardous areas, and the systematic identification and control of ignition sources to prevent major accident.
Hazardous areas are defined in DSEAR as “any place in which an explosive atmosphere may occur in quantities such as to require special precautions to protect the safety of workers”. In this context, ‘special precautions’ is best taken as relating to the construction, installation and use of apparatus – this could include electrical, instrumentation or mechanical equipment providing heating, lighting, or ventilation to the plant.
To ensure site and process safety all equipment located in hazardous areas must be correctly specified and certified according to international classifications such as ATEX.
A Guidance Document published by the HSE can be downloaded here and aims to help dutyholders comply with the Control of Major Accident Hazards (COMAH) Regulations 2015. Furthermore, the COSHH e-tool provides advice on controlling the use of chemicals for a range of common tasks and controlling associated health risks during industrial processes such as mixing or drying.

Hazardous areas are classified into zones based on an assessment of the frequency of the occurrence and duration of an explosive gas atmosphere, as follows:
Various sources have tried to place time limits on to these zones, but none have been officially adopted. The most common values used are:
Recommendations
The following companies provide Hazardous Area Studies to ensure COMAH sites are compliant to their obligations according to DSEAR.
