B,C,D are correctA- INCORRECT -should read.may be necessary to dismantle the scaffold to leave the area in a safe condition. This must be done from the interior of the building.3.5 GS
T/F?At no time shall any member go out onto an unoccupied scaffold.
True All operations shall be conducted from within the building or from the roof level. Members operating near windows or roof edge shall take precautions against falling, including utilizing safety lines. Avoid operating below the scaffold to avoid being struck by the scaffold, or falling building material.4.3 GS
OCCUPIED STALLED SUSPENDED SCAFFOLD These emergencies are frequently caused by which of the following? more then one correct.A- Tripped breakersB- Overheated hoist motorsC- Loose electrical connectionsD- Overload on scaffoldE- Tiebacks on roof not secured
A,B, C are correctTOET-Tripped breakersO- Overheated hoist motorsE- Electrical Loose connections5.1 GS
For an OCCUPIED STALLED SUSPENDED SCAFFOLD removal what is the last resort and how is it done?
Window removal to retrieve stranded workers is used as a last resort due to the damage that may be caused to the building and the danger of falling glass. Evaluate worker’s condition, ETA of mechanic, weather conditions, difficulty of window removal, etc. prior to commencing this operation. If it is intended to haul in workers through an open window, and they must disconnect from their safety line to enter window, you must:• Attach snap hook of life saving rope to worker’s harness.• Secure other end to a substantial object.Additional considerations:• As long as the workers are not injured, remain calm, and remain attached to their safety lines, they are in no danger.• It may be best to await the arrival of the scaffold mechanic to correct the condition.5.3 5.5 GS
OCCUPIED HANGING OR OFF-LEVEL SUSPENDED SCAFFOLD-The scaffold will be found severely tilted or hanging on one side. This is usually caused by one hoist motor stopping while the other continues to descend. Situation can also be caused by a failure of the anchoring/rigging systems at the roof. Be aware that further collapse may occur.1- Pertaining to retrieval procedures at this type incidents which statements are correct?more than one.A- Locate a window nearest scaffold.
