It's precisely because of the various stages in the act where we don't have tailoring of what to do and when, in respect of the most dangerous substances, that we need to be more specific about how to implement precaution. It doesn't mean, for example, plugging in that word “precaution” at every one of those stages, but being more mandatory at different stages. It's the tailoring of discretion, as I was talking about earlier, that would best achieve the more mandatory taking of precautionary measures throughout the act.
