Earthquake preparation in a tower condominium does not end with the building's seismic performance. Indoors, furniture that tips, falls, or moves can cause injuries and block escape routes. The Tokyo Fire Department advises that, on roughly the 10th floor and above, preventing movement from long-period ground motion is important in addition to conventional tip-over and fall prevention.Tokyo Fire Department: Measures to Prevent Furniture from Tipping, Falling, and Moving

Do not start by buying restraints. Proceed in this order: avoid placing the item or change its position; verify the wall and ceiling construction; choose devices for each piece of furniture; and inspect for looseness after installation. Before work affecting a rental unit or common property, check the building rules and obtain confirmation from the landlord or manager.

First, arrange furniture so it cannot block people or exits if it falls

Near beds, sofas, and work-from-home seats, check the direction in which furniture could fall and the reach of drawers that could slide out. Keep tall furniture away from doors and hallways, leaving enough width to pass even if it falls. Move heavy items to lower shelves and consolidate seldom-used items in a closet or built-in storage. Restraints come after reducing hazards through placement.

The Fire and Disaster Management Agency also explains that even when a building remains intact, falling furniture can injure people or block escape routes. Reviewing how much furniture you have and where it is placed can reduce both the number of restraints needed and the risks that remain afterward.Fire and Disaster Management Agency: Preventing Furniture Tip-Overs

Not every wall can accept screw anchors

Apartment walls can include concrete with a direct finish, partition walls with framing, and walls containing insulation to prevent condensation. The Fire and Disaster Management Agency explains that some types, including S1 and GL walls, cannot accept direct furniture anchoring. Do not decide from appearance or tapping sounds alone; confirm the substrate and whether anchoring is allowed using drawings, handover documents, the management company, or the contractor.Fire and Disaster Management Agency: Not Every Wall Can Be Used for Anchoring

L-brackets that use screws work only when both the wall substrate and the furniture are strong enough. Do not fasten them only to the surface of unsupported plasterboard or to a thin furniture back panel. Drilling into a rental unit or the building frame can affect restoration obligations and building rules, so do not carry out the work without authorization.

When screws cannot be used, do not rely on a single device

When wall anchoring is not possible, one option is to combine a compression pole above the furniture with a stopper or adhesive device at its base. This requires a ceiling able to withstand the force and a gap within the product's specified range. Do not install against a soft or suspended ceiling contrary to the instructions.

Furniture movement varies with shape, weight, flooring, building structure, and floor level. The Fire and Disaster Management Agency describes several patterns, including rocking migration, in which tall furniture rocks back and forth while moving. Choose a method suited to the furniture and mounting surface instead of relying on one device with a high load rating.Fire and Disaster Management Agency: How Furniture Falls

Check refrigerators, doors, glass, and casters separately

Use the refrigerator's designated anchoring points and a suitable wall substrate while preserving the required ventilation clearance. For a cabinet, treat restraint of the cabinet itself, latches for doors and drawers, and shatter protection for furniture glass as separate measures. Securing only a TV or microwave stand does not stop the appliance from falling, so check how the appliance itself should be restrained.

The right method for a wheeled cart or TV stand depends on whether it needs to move during normal use. For items that stay in place, lock the casters and add a movement restraint. For items moved regularly, establish a routine for securing them in a designated position after use. Window film requires checks for thermal-breakage risk and building rules, so do not treat windows the same as glass in furniture.

Record the installation date and inspect every six months and after rearranging

For each installed restraint, record its location, product name, installation date, rated load, and how the substrate was verified. Check 2 times a year, such as in spring and fall, for loose screws, straps, adhesive surfaces, and tension devices, and inspect furniture deformation and ceiling abnormalities. Reassess the setup after moving, rearranging furniture, changing flooring, or adding stored items.

Restraints do not guarantee safety. After an earthquake, check for leaning or damage before approaching furniture or walls, and consult the manager or a qualified contractor if there is danger. Narrow product candidates using the checks below and do not use a device when the instructions do not match the installation.
