Two similar answers:

1) too much safety is when the ‘safety’ eliminates too much of the challenge/risk.  We need challenge to grow.

2) too much safety is when the ‘safety’ has minimal failure event impact. Some good examples of this are:  a) pfd for everyone – huge impact on failure events, so great. b) heaving line for everyone – minimal impact on failure events, so too much.
