There may be reasons for flexibility in applying the regulations. From our perspective, you always have to look at the safety. We've seen weaknesses in the risk assessments done by the companies or the regulator that have contributed to accidents in the past. It might be too restrictive to say there can never be an exemption, but I think they have to be dealt with carefully to make sure that safety isn't compromised.
