circular bund is one of the common features used around the storage tank where flammable or toxic liquids are held for example ethylene. Determine the incident thermal radiation on a person m height, standing $15$ m from the circumference of the bund if the ethylene leaks and occupies the bunded area, assuming the ethylene tank is surrounded by a circular bund with a diameter $30$ predict whether the person would be fatality injured or safe if the ethylene leaked ignites.Propose additional measures to reduce or prevent this incident.
