Comparison of Safety Performance Notes Rates are calculated in accordance with RIDDOR 1995 definitions (ie injuries resulting in more than 3 days absence from work. Rates are rolling twelve month averages. HPC trace starts at award of FID. (October 2016) Other projects AFR rates are shown at same relative time on project schedule. For comparison, Tideway AFR-3 for March 2018 = 0.10; HPC AFR-3 for March 2018 = 0.05. 20 CHSEC Presentation Aug 2017 NOT PROTECTIVELY MARKED 15 Aug 2017 EDF Energy plc. All rights Reserved.
