Based in Winchester and with offices in India and the Middle East, we provide laboratory and consultancy services to the process industries. Working to ISO/IEC 17025: 2017 our laboratory generates test data on the flammability, explosivity and thermal reactivity of dusts, gases, vapours and substances. Our Process Safety Consultants provide a wide range of specialist technical safety services including Process Safety Management, DSEAR / ATEX, Comprehensive Safety Audits, HAZOP, HAC, Vent Sizing, Chemical Reaction Evaluation, Training, and incident investigation.
Technical Update – January 2021
The Minimum Ignition Temperature (MIT) test is conducted to
determine the lowest temperature at which a hot surface will
ignite a powder when dispersed in air, as a dust cloud. Read More
Technical Update – November 2020
Flammability testing is required to complete your basis of
safety regarding DSEAR/ATEX. The data obtained from such
tests will enable you to establish whether you can rely on,
Avoidance of Ignition Sources, Explosion Prevention or
Explosion Protection as your basis of safety.Read More
Technical Update – October 2020
The COVID-19 virus has had a profound impact on travel and
business operation, resulting in many new challenges for
industrial operating facilities. One of these is the
completion of Hazard and Operability (HAZOP) studies. Read More

The difference between flammability and combustibility
The words ‘flammable’ and ‘combustible’ are
frequently used interchangeably but they are different
chemical properties. There is a sense in which we suspect
that they mean different things, but for the most part it
seems that there is a difference without a distinction...Read More
HAZOP study was completed for solvent bulk storage and distribution plant handling flammable and toxic chemicals. The study covered normal operation, start-up, shutdown, maintenance and emergency operations. Our expert facilitator chaired the HAZOP session and our scribe took notes using a software.
DSEAR Assessment was completed for multiple sites all around the UK. These assessments were necessary for identifying hazardous areas to reduce the risks of explosive atmospheres.
Dispersion and Consequence Modelling was conducted for toxic chemicals stored and handled in the facility to estimate cloud dispersion and distances for hazardous concentrations.
Our experts helped the company to form guidelines for Hazardous Area Classification with predefined examples and calculations for their plant areas and unit operations. Based on these guidelines, existing Hazardous Area Classification reports were reviewed for their plants all around the globe.
LOPA (Layer of Protection Analysis) was carried out for the chemical facility handling multiple hazardous chemicals, high pressure & temperature unit operations. Based on LOPA, risk reduction measures with required Probability of Failure on Demand (PFD) were suggested.
Our ISO 17025 certified laboratory helped the facility to identify flammability properties (such as MIE, MIT, LIT, Explosion Severity – Kst & Pmax, MEC, LOC) for Flour, Sugar, Spices, etc. and further helped them to interpret the properties to establish adequate Basis of Safety for their operations.
"Consultants at Sigma HSE have done a great job in providing a practical and cost-effective solution for DSEAR / ATEX implementation". The team's technical expertise has made the whole process very simple and easy to follow for our staff"
"Detail-oriented approach of the consultants has helped our team in identifying various risks & hazards involved in different stages of the project and helped us in making design and operational changes at the right time"
"It was great working with the Sigma HSE team, as this was our first time working with a vendor on a bigger scale for process safety management. The team was diligent and articulate, and ultimately we are thrilled with the end result and level of awareness among our employees for the safety culture"
"Sigma HSE completed successful DSEAR Assessment for multiple sites parallelly all around the UK with flawless execution. Considering inventories of flammable chemicals these assessments were crucial in identifying hazardous areas to reduce the risks of explosive atmospheres at our sites. Thanks to Sigma HSE team our operation is much safer now."
