CBA CBA Structural Rigging & Advanced Installation 2 — Questions and Answers
Question 1: Which balloon inflation method produces the longest float time for latex balloons?
- Pure helium inflation to maximum size
- Hi-float treatment followed by inflation to approximately 80% of rated capacity (Correct answer)
- Air inflation with a sealed knot
- Oxygen-helium blend inflation
Correct answer: Hi-float treatment followed by inflation to approximately 80% of rated capacity
Hi-Float coats the interior of latex balloons, dramatically slowing helium permeation and extending float time from hours to days.
Question 2: When installing a balloon ceiling treatment in a venue with an active HVAC system, what is the MOST important consideration?
- Matching balloon colors to the duct color
- Ensuring balloon clusters are secured so air currents cannot dislodge them, and checking that vent positioning won't accelerate balloon deflation (Correct answer)
- Turning off the HVAC during the installation only
- Using only foil balloons since they are unaffected by airflow
Correct answer: Ensuring balloon clusters are secured so air currents cannot dislodge them, and checking that vent positioning won't accelerate balloon deflation
Active HVAC systems can dislodge unsecured balloons, accelerate drying in latex, and create unpredictable movement — securing clusters properly is essential.
Question 3: A CBA is building a 10-foot balloon column using the round base method. What is the recommended balloon size for the bottom tier to ensure structural stability?
- Same size as the top tier balloons
- Larger balloons (16" or 18") at the base, graduating to smaller sizes toward the top (Correct answer)
- Smallest balloons at the base to concentrate weight
- All balloons must be the same size for uniformity
Correct answer: Larger balloons (16" or 18") at the base, graduating to smaller sizes toward the top
Larger balloons at the base of a column create a wider, more stable foundation that distributes weight and prevents the column from tipping.
Question 4: What is the purpose of using a balloon sizing box (gauge) during professional installations?
- To count how many balloons are in a cluster
- To ensure consistent balloon inflation size across all clusters, creating a uniform and professional appearance (Correct answer)
- To measure the venue dimensions
- To test helium purity
Correct answer: To ensure consistent balloon inflation size across all clusters, creating a uniform and professional appearance
A sizing gauge ensures all balloons are inflated to a consistent diameter, resulting in even, professional-looking clusters and garlands.
Question 5: When creating a balloon mosaic or photo backdrop, which attachment method best prevents balloon movement while maintaining a flat surface?
- Tying balloons directly to a fence or frame with their knots
- Using a grid framework (chicken wire, pegboard, or PVC grid) with balloons inserted or tied to each grid opening (Correct answer)
- Stacking air-inflated balloons without any frame
- Gluing deflated balloons to foam board
Correct answer: Using a grid framework (chicken wire, pegboard, or PVC grid) with balloons inserted or tied to each grid opening
A grid framework gives each balloon a fixed position, creating a flat, uniform mosaic surface with minimal movement or bulging.
Question 6: What is the MOST important reason to calculate the number of balloons needed before ordering supplies for a large installation?
- To minimize the number of balloon colors used
- To avoid costly over-ordering or project-halting shortages, ensuring accurate job costing and client pricing (Correct answer)
- To satisfy venue management requirements
- To match competitor pricing
Correct answer: To avoid costly over-ordering or project-halting shortages, ensuring accurate job costing and client pricing
Accurate balloon counts prevent supply shortages mid-installation and over-purchasing that erodes profit margins.
