■ What is Ladder Safety Guardian?

One of the most common types of fall accidents at construction and landscaping sites is accidents involving portable ladders.

Ladder Safety Guardian is a reference safety information tool designed to help you work more systematically and safely when you inevitably have to use a Type A (footrest/landscaping) portable ladder.

This app does not recommend the use of ladders. Its purpose is to guide you in measuring the height of the work site, selecting the appropriate equipment for that height, inspecting the condition before use, and adhering to safety rules. It references domestic standards (KOSHA, KS, and Occupational Safety and Health Standards).

■ Main Features

· Ladder Selection — Entering the work height (1.5–6m) provides information on the recommended equipment grade, the number of ladder steps to select, the maximum number of steps you can stand on, and essential safety conditions (safety helmet, two-person team, safety harness, etc.).

· Ladder Condition Check — Displays 9 common items for Type A ladders to check before use, along with example photos. Tapping an item allows you to view the example photo in a larger size.
· Ladder Safety Rules — Provides 12 work safety rules along with large illustrations, the full text, and supporting legal provisions.

· Accident Videos — Learn about potential hazards in advance through videos that recreate accident situations involving falls, collisions, and electric shocks.

These are AI-generated reenactment videos, not actual footage of accidents, and are included in the app for offline playback.

· Ladder History Management — Register, modify, and delete owned ladders in the registry, and share the list with colleagues via QR code or scan it to retrieve it.

■ Recommended for:

· Workers who use A-frame portable ladders directly in the field

· Safety personnel who manage and educate on ladder usage safety

· Those who want to quickly verify the appropriate ladder and safety conditions before work
