Safety engineering postgraduate personal statement example

Personal statement example

My degree in chemical engineering finished with a design project on a small solvent recovery unit, and the part I remember best was not the column sizing but the HAZOP-style review our group was asked to run on our own flowsheet. We found that the reflux drum vent we had cheerfully drawn would, under a plausible cooling water failure, have discharged something flammable at head height near a walkway. That exercise stayed with me far longer than the calculations, and eight years of shift work have only sharpened my interest in why plant that looks safe on paper behaves differently at three in the morning.

Since graduating I have worked at a water treatment and industrial effluent site, first as a process operator and now as a shift technician. Much of the job is routine: dosing control, sampling, chlorine and ferric deliveries, sorting out blinded screens and tripped pumps. What has shaped my thinking is the gap between written procedure and actual practice. Our confined space entries into balance tanks are properly controlled, but I have seen how easily a gas monitor gets taken on trust, how often a job is scheduled at the least convenient point in a shift, and how small changes to a pipework run quietly accumulate until the drawings no longer match the plant. For the last two years I have coordinated permits to work on my shift, which means challenging colleagues and contractors I know well, and explaining to a fitter who has done a task a hundred times why this occasion needs isolation proving. Those conversations taught me that safety engineering is partly technical and partly about giving people reasons they find credible.

I wanted a better grounding than experience alone, so I completed the NEBOSH General Certificate, largely in my own time. It gave me useful language for risk assessment and legal duties, but it also showed me the limits of what I currently know. I can describe a bow-tie diagram; I cannot yet assign defensible failure rates to a protection layer or work through a LOPA properly. I would like to be able to do quantitative risk assessment, consequence modelling for releases and dispersion, and reliability analysis with some rigour rather than by borrowing other people's numbers. Reading Trevor Kletz on inherently safer design made me look again at our own chemical storage, where the answer to several hazards would have been less stored inventory rather than more interlocks.

To prepare for returning to study I have been working back through thermodynamics and fluid mechanics from my old textbooks, and taking an online course in probability and statistics because my degree statistics were thin and I know reliability work depends on them. I have also been practising in Python, mostly writing small scripts to pull trends from our SCADA exports and look at how often particular alarms recur; it is modest work, but it has made me comfortable handling data rather than intimidated by it.

Outside work I lead a weekly group run at my local club, which involves route checks, keeping an eye on newer runners and deciding when conditions are poor enough to change plans. It is a small responsibility, but it is the same habit of thinking ahead about what could go wrong for people who are relying on you.

I am applying now rather than earlier because I finally have the financial position and the motivation to study properly. In the longer term I want to work as a process safety engineer in the water or chemicals sector, ideally in a role that includes hazard studies and design review. A taught master's, with a project I can ground in real operating conditions, is the most direct way for me to become genuinely useful in that work rather than simply experienced.
