Hazard:
a dangerous condition, either potential or inherent, which can interfere with the expected, orderly progress of a given activity
a measured or calculated chance of exposure to hazard(s) which may or may not result in loss
Both should be managed!
Accident:
an unplanned and therefore unwanted or undesired event resulting in physical harm and/or property damage
an unplanned event that did not but could have resulted in physical harm and/or property damage
Both should be investigated!

Look at past accidents for your first step in Accident Reduction.
Were prior hazards adequately resolved?
What work controls were implemented to prevent recurrence, and are they working?
People
Equipment
Material
Procedures
Work Environment
Failure "here" may cause failure "there"
