The Chemical industry has always been considered a focus of concern for the general population and especially for the surrounding population due to the potential severity of an accident. Unfortunately, recent examples related with chemical processes or substances have contributed to it.
Step by step, chemical companies have improved their safety standards in order to reduce the frequency and the severity of potential incidents. Therefore, methods like the Hazard and Operability Study (better known as HAZOP) are used by large companies to make their processes safer with the environment and people in mind. However, these methods demand a huge effort for small or medium-sized chemical companies, the most common situation in Europe.
On the other hand:
- Unexpected or runaway reactions seem to be the main technical causes and
- Inadequate or incorrect process analysis, inappropriate plant design or operational procedures and inadequate instructions appear among the most common organizational causes of an accident.
How does Lebsa make its industrial activity compatible with the environment and surroundings?
With this scenario LEBSA’s team understands the importance of making their industrial activity compatible with the environment and surroundings. The importance of being a trusted partner in the global pharmaceutical market for generic API manufacturing in Europe. Therefore, a well-designed chemical process from a safety point of view appears as a strategic key factor to achieve the above mentioned goals:
- Respect for the environment and people and
- To become a flexible partner, customer-centred, and committed to successful long-term business relationships.
Regarding safety chemical processes, it’s important to figure out the most appropriate method for hazard identification to be implemented in LEBSA, a SME (Small and Medium-sized Enterprise) with a multi-purpose facility design and batch production manufacturing method. Being quite common that those used by big companies demand huge human and economic resources to be dedicated to. In this sense, the possibility to use simple tools, easy to use by non-experts in the field of safety, could be of interest for a small or medium-sized company.
Use of HarsMeth methodology for increased safety
In such situations HarsMeth methodology should be a good alternative to be taken into account. It’s a methodology for the hazard assessment of chemical processes, being well-structured to offer excellent assistance for the safety analysis of batch (as well as semi-batch processes) in an easy structured way by using basic rules and methods designed as an interface between experts and SMEs.
This method was developed by the HarsNet Network (2007) funded by the European Commission (Nomen, Sempere, Sales, & Ghinaglia, 2002), which was active between 1998 and 2002.
The hazard assessment of a chemical reaction is performed by means of a set of five checklists (Figure 1):
