Bouncy Castle Safety Checklist for GTA Parents

A bouncy castle is one of the safest ways to keep a group of young kids happily busy, when it's set up and run properly. Most bouncy castle injuries come from a handful of preventable situations: too many kids at once, big kids bouncing with small ones, a castle not anchored properly or bouncing continuing as the wind picks up. Every one of them can be avoided with a little planning and an adult who's paying attention.

If you're about to host a party with a bouncy castle and want to be sure it runs safely, here's the checklist to follow, from setup and anchoring to supervision and weather limits. Bouncy castle safety comes down to proper anchoring on a flat surface, a responsible adult supervising at all times, small groups of similar-sized kids, no shoes or food inside and stopping immediately in strong wind or storms.

1. Setup and anchoring

A safe castle starts with a safe setup. Your rental company should:

• Choose a flat, level surface clear of debris
• Anchor the castle with stakes on grass or heavy sandbags on hard surfaces
• Place the blower so its tube isn't kinked and kids can't reach the intake
• Leave a clear buffer zone on every side
• Check that the castle is fully and evenly inflated before kids go in

If anything looks loose, sagging or uneven, ask the team before they leave. LUNO's team sets up and checks every castle on delivery.

2. Choose the right spot

Avoid slopes, areas near fences, walls, pools, decks, trees with low branches, barbecues and driveways. The castle should be on a flat area with room around it for kids to climb out safely. Our guide to how much space a bouncy castle needs explains the buffer zone.

3. Supervision is non-negotiable

A responsible adult should watch the castle the entire time kids are using it, not glancing over from the barbecue but actually watching. Many parents take turns in 20-minute shifts. The supervisor's job:

• Control how many kids are inside
• Group kids by size and age
• Stop rough play, flips and wrestling
• Clear the castle immediately if something goes wrong

LUNO can arrange supervised play for your party; ask when you book.

4. Rules for kids

Explain the rules before the first bounce, and post them by the entrance:

• Shoes, glasses, jewellery and hair clips off
• No food, drinks, gum or candy inside
• No flips, somersaults or climbing the walls
• Bounce in the middle, away from the entrance
• Get out slowly, feet first

Keep it short and repeat it with each new group.

Make sure kids know what to do if the castle starts to deflate: stay calm, move toward the entrance and climb out feet first with an adult's help. A quick explanation before the first bounce means nobody panics if the power cuts out.

5. Age and size groups

Mixing a six-year-old and a two-year-old in the same castle is where many bumps happen. Run separate sessions for toddlers and older kids, and keep teens and adults out entirely. LUNO's castles are designed for ages 2 to 6.

6. Weather limits

• Wind: The biggest risk. If gusts pick up or the castle starts to move or flex, get everyone out and deflate it.
• Rain: Wet vinyl is slippery. Stop bouncing during rain and dry the castle before kids return.
• Heat: Vinyl can get hot in direct sun. Use shade, give water breaks and check the surface temperature.
• Storms: Deflate at the first sign of thunder or lightning.

7. Power and the blower

The blower must stay on for the castle to stay inflated. Use a grounded outlet, keep the cord away from walkways and don't share the circuit with high-draw equipment. If the power cuts out, get kids out calmly and quickly as the castle deflates.

Keep a basic first aid kit and a phone nearby, and know the address of your nearest urgent care clinic. You'll almost certainly never need them, but a supervisor who's prepared is calmer and quicker if a child bumps their head or twists an ankle.

8. Questions to ask your rental company

• Is the castle cleaned and inspected between rentals?
• Do you carry liability insurance?
• How is the castle anchored on my surface?
• What's the maximum number of kids at once?
• What's your weather and cancellation policy?

Clear answers to these questions are a good sign.

Example: when the wind picks up mid-party

Say it's 3 p.m. at your party, and gusts start shaking the trees. The supervising adult calls all the kids out of the castle, calmly and one at a time, feet first. Unplug the blower once everyone's clear, and keep kids away while it deflates. Move the party to games or cake and call the rental company if you're unsure. If the wind drops later, the castle can be reinflated; if not, the party carries on without it.

When to bring in a rental company

Book a company that sets up, anchors and checks the castle for you, and that can answer every question above.
