Maint. / Construction Responsibility

29. Critical Lift
Critical lifts are defined as high risk lifts where there
is a potential for serious injury, major property loss,
or disruption of programs or projects. The following
are examples of the critical lifts:
1. Around energized electrical lines.
2. Near or over hydrocarbon loading piers.
3. On barges, vessels and hydrocarbon loading piers.
4. Around and over populated/traffic areas.
5. Tandem, multiple or tailing lifts.
6. On rubber or pick and carry lifts.
7. Personnel Platforms (man lifts)
8. High level or long reach lifts.

30. SAFETY PRECAUTIONS
 Crane & accessories shall be kept in good condition.
 The crane shall have a sticker updated every three
