We aim to identify the brightest hot emission lines in Hinode EIS spectra, and suggest the best ones to be used in flare observations. The EIS database was searched in order to find suitable datasets to identify the prominent lines. A B2-class flare spectrum was found. Most previous identifications are confirmed, however some are revised by noting the presence of blending. A new self-blend is identified. A recommended list of emission lines formed at high temperatures is provided. The brightest lines are the 192.85 Å and the 192 Å, however they are blended. The best unblended lines are the 200.99 Å, 269.42 Å and 263.76 Å lines.
