CBA CBA Structural Rigging & Advanced Installation 3

Question 1

Which factor MOST significantly affects the float height of helium-filled latex balloons in an outdoor environment?

Accepted Answer

Ambient temperature — heat causes helium to expand and balloons may burst; cold reduces lift

Answer

The brand of balloon used

Answer

The color of the balloon

Answer

Whether the balloon was tied with a ribbon or monofilament

Question 2

When disassembling a post-event balloon installation in a venue, what is the MOST responsible disposal practice for latex balloons?

Accepted Answer

Burst and bag all latex balloons for trash disposal, following local waste and environmental guidelines

Answer

Release them outdoors so they biodegrade naturally

Answer

Leave them for the venue cleaning crew

Answer

Reuse all balloons for the next event

Question 3

Which type of balloon is best suited for a long-term (multi-day) indoor installation where maintaining inflation is critical?

Accepted Answer

Foil (mylar) balloons, which have much lower helium permeation rates than latex

Answer

Standard 11-inch latex with pure helium

Answer

Latex balloons with maximum over-inflation

Answer

Micro-foil balloons filled with air only

Question 4

What is the primary reason a CBA should avoid over-inflating latex balloons when creating organic garlands?

Accepted Answer

Over-inflated balloons have reduced elasticity, higher pop risk, and shorter lifespan — especially in warm or sunny conditions

Answer

Over-inflated balloons are harder to tie into clusters

Answer

Clients prefer under-inflated garlands aesthetically

Answer

Over-inflation wastes helium

Question 5

Which rigging technique is MOST appropriate for suspending a heavy balloon cloud installation from a drop ceiling tile grid?

Accepted Answer

Use drop ceiling butterfly clips or bar hangers attached to the grid rails, rated for the load weight

Answer

Tape the balloon strings directly to the ceiling tiles

Answer

Hook balloons to the fluorescent light fixtures

Answer

Use standard push pins into the tiles

Question 6

During a balloon arch installation, a CBA notices that the monofilament spine is cutting into some balloon knots under tension. What is the safest corrective action?

Accepted Answer

Reinforce the affected knots with rubber balloon strips or redistribute the load by adding additional anchor points along the spine

Answer

Continue and monitor — some tension is normal

Answer

Replace the monofilament with rope

Answer

Remove and reinstall the arch using only helium to avoid spine tension
