Logo critique and ideas required

[basils57]

Our small company (a Health and Safety Consultancy), has been using the attached logo since we founded 4 years ago, and think the time might be ripe to re-hash it.

Could I therefore please ask for a critique of what we are using and any suggestions as to how it is felt we could improve our image with a redesign?
We would want to keep the white cross on the same green background as part of the logo. Although the word 'Direct' is emphasised on the current logo, this doesn't necessarily have to be - if anything 'safety' is the prime word.

Thanks
