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.
