The XD03.13 Industrial Rigging & Signaling Standard Task Evaluation (STE), established by the Electric Power Research Institute (EPRI), allows qualified Boilermakers nationwide to work at any jobsite throughout the United States that requires this qualification.


To obtain this qualification, workers must meet the following minimum requirements:
• Have a current MOST drug card
• OSHA 10
• Be either a graduate apprentice, currently enrolled in the BNAP, or have a minimum of 6,000 hours as a field construction Boilermaker

Qualifying for this STE is a two-part process.

Part One: Written Test
Workers must first pass an online, 120-question written test. Tests are administered by BNAP certified STE Evaluators. There is a two-hour time limit for this test. The passing score for this test is 80%. Workers are tested on their knowledge of the following topics:

• Vendor materials
• Regulatory requirements
• Mathematical problem solving
• Rigging inspection techniques
• ANSI hand signals
• Rigging equipment characteristics
• Weight calculations
• Load path requirements
• Load movement safety
• Load characteristics
• Load restraint requirements
• Cribbing requirements
• Rigging installation
• Rigging adjustment techniques

Part Two: Hands-on Performance Evaluation
After successfully passing the written test, the worker must pass the hands-on performance evaluation. This evaluation is administered by a BNAP certified STE Evaluator and must be performed at a BNAP-approved testing site. Workers have three hours to complete the hands-on performance evaluation.

During this evaluation, workers must successfully lift, transfer, place, and land a load. This evaluation involves numerous critical steps. Each step must be performed successfully for the worker to pass. All critical steps are must-perform steps. Workers are graded on the following:

• Ability to successfully complete all aspects of the lift
• Proper inspection of all rigging equipment used in conjunction with the lift
• Knowledge and proper use of hand signals
• Proper use and inspection of all personal protective equipment
• Removal and final inspection of equipment
