a.
PPE
b. Documentation requirements for the task (seral numbers, batch numbers, pressures etc.)
c.
Conversions and pressure charts
d.
LOTO
e.
Site procedures
f. Tool maintenance requirements, e.g. control tool lubrication levels etc.
Based on the scenario documents, facilitate activities where participants identify and select the correct bolts, washers and nuts needed to complete the task to specification. The activities should require participants to consider:
