Is there a person in the work area that can initiate basic rescue, if a fall
should occur?
Are equipment / tools used at height controlled and adequately secured
against dropping? And not left behind finishing the work?
Are underlying areas closed off and pressurized/sensitive equipment
protected against dropped objects?
Are lighting, noise and weather conditions satisfactory for the task?
Are there any other risks and have they been evaluated and found
acceptable? Use the 4 – Point Risk assessment
