process safety is to apply risk management systems theory. This
includes recognition of the hazards posed by the process, and a
continual effort to analyse the risks, and to reduce or control them
to the lowest levels practical, while balancing other business
objectives. Process Safety related Legislation require manufacturing
plants to identify if they are working with hazardous substances that
may have a potentially explosible nature and put in place measures
to remove or mitigate the effect of potential fires and explosions.

Electrical Safety Process Safety
Electrical hazards are a source of continuous risk to safety of people
and property, since they can act as a source of shock and fire.
Laboratory Testing Services
Although in processing areas, electrical sparks are hazardous since ISO/IEC 17025 Accredited
they can act as a source of ignition for flammable atmosphere such Sigma HSE (UK) Laboratories provide accurate test data that can
as vapor, gas, dust cloud dispersed in air in appropriate determine whether a material is flammable or chemically reactive
concentration. However, the same electrical sparks/ short circuiting and if so what test data is required to ensure a risk assessment can
can act as a source of fire in panel rooms, server rooms, battery be performed. Typical test data are:
rooms, cable trays, etc. Fire related to electrical sparks are not only
relevant for processing industry but also for IT, telecommunication, Fire & Explosion Properties
Hospitality, Healthcare and banking industries.

Chemical Reaction Hazards Testing
Many industrial processes involve the mixing and blending of materials/chemicals where the
reactions can often produce exothermic energy which has the risk of becoming a runaway
reaction unless appropriate dosing and cooling controls are in place. Sigma-HSE can provide
scale-up and DIERS calculations to ensure your process remains safe or in the event of a
runaway reaction the effects are mitigated. Tests available include:
 Adiabatic Calorimetry (VSP2)
 Heat Flow Calorimetry (Mettler RC1)
 Isothermal Calorimetry (Mettler RC1)
 Reaction Calorimetry (Mettler RC1)
 Small Scale Screening Tests (DSC, ARC, Carius Tube, VSP, etc.)

Training
Sigma HSE can provide bespoke training packages in all the above areas of concern and can
focus the training on specific levels of management from operator level through to
management/ engineers level.
