Fortunately, even though we are constantly exposing our hands to varying degrees of risk, many of the injuries suffered are relatively minor, such as small cuts, abrasions and minor infections.

This program looks closely at the main hazard groups (mechanical, chemical, thermal and general hazards) and the accident prevention measures that can be addressed (elimination, substitution, administrative controls and engineering controls).
