Good morning All, Can anyone help me I need user friendly DSEAR Risk assessment form to assist a client and ensure compliance at a bio fuel plant. Appreciate your help Kind Regards Ian.

m You could come unstuck using this method. There are various well established standards available, used to estimate and calculate the extent of hazardous DSEAR zones and the probability of ignition. Following best practice/recognised methods, would be expected.

Ian, No to sure about asking for a user friendly form to "assist" a client, would have thought that they have hired you to assist them? First port of call is the completion of a hazardous area classification: Identify sources of release. Identify the frequency and duration of release. Determine the release rate, density, concentration and velocity. Calculate the minimum volumetric flowrate of air required to dilute Vz to below LEL plus the necessary safety factor. Estimate the hypothetical volume of the explosive atmosphere. If not a continuous release, then calculate persistence time. Estimate the degree and availability of ventilation provided. Taking into account the grade of release versus ventilation, determine the appropriate hazardous area (Zone 0, 1 or 2). Alternatively, suggest to your client that they should consider hiring some one experienced in this area.

Not the prettiest form but a start on this page: http://www.safety.ncl.ac.uk/dsear.aspx I would transcribe it to Excel then use new tabs to show subsequent assessments
