(1) The personnel lift supervisor must:

(a) Supervise the personnel lift operation;

(b) Verify all crane/derrick and platform inspections have been accomplished as outlined in this part;

(c) Inspect the area for potential hazards, any hazards found during this inspection must be reported to the employer prior to performing the personnel lift. This inspection must include, but not limited to:

(i) Excessive load and/or radius;

(ii) Overhead obstructions and electrical transmission lines;

(iii) Hazardous locations;

(iv) Inadequate surface and support to withstand all forces imposed;

(v) Wind, weather, and unstable conditions;

(vi) Any potentially hazardous conditions.

(d) Verify the base of the crane is level in accordance with manufacturer's recommendations and in no case greater than one percent of level;

(e) For crane/derrick with a boom-attached platform, verify that the platform is attached as specified by the platform manufacturer and crane/derrick manufacturer or qualified person;

(f) Not allow the total weight of the lifted load, including rigging, platform, personnel, tools, and material, to exceed 50% of the crane/derrick's rated load, under the planned conditions of operation (except during testing as outlined in WAC 296-155-55115).

(g) Not allow the platform's rating or the crane's/derrick's reduced rated load to be exceeded when loads are transferred to the hoisted platform.

(h) Verify a trial lift has been performed as outlined in WAC 296-155-55115.

(i) Verify that during the trial lift, the platform is loaded to at least the weight expected during the actual lift.

(j) Not allow the crane/derrick to travel with personnel in the personnel platform except when the crane/derrick runs on fixed rails or runways.

(k) Verify the platform is securely attached to the crane or derrick.

(l) Verify the load line is not attached to or wrapped around the platform.

(m) Verify boom-attached personnel platforms are attached according to manufacturer's specifications or a qualified person.

(n) Keep people from passing under the raised platform.

(o) Ensure there are no more people on the platform than are needed to do the job.

(2) The personnel lift supervisor must ensure the crane/derrick and platform manufacturer's information is consulted for specific instruction on the crane/derrick operation. The crane/derrick and platform operation instructions in this part are intended as minimum criteria.

(3) The personnel lift supervisor must ensure there are an appropriate number of signal persons, ground crew, and platform occupants to perform the personnel lift safely. In suspended and boom-attached platforms without boom motion controls, one occupant must be designated as the platform signal person. This person must be responsible for communicating with the operator and/or other designated signal persons.
