Safety and health disclosure starts August 1: what to prepare

Workplace Safety Field Guide special edition: safety and health disclosure

Three weeks remain until August 1. On that date Korea's safety and health disclosure duty takes effect: under Article 10-2 of the Occupational Safety and Health Act, corporations with 500 or more regular workers and major public institutions must disclose their safety and health status. The duty follows from the joint government worker-safety plan announced by ministries on September 15, 2025 (Ministry of Employment and Labor press release, policy briefing). The amended Act itself took effect on June 1; only the disclosure duty starts August 1.

If your regular headcount sits near the 500-worker line, confirm coverage before doing anything else.

Five items, none of them a one-day document

The disclosure covers five items.

1. Safety and health management structure
2. Occupational accident history
3. Safety and health activities and plans
4. Safety and health investment
5. Recurrence prevention measures

Each draws on a different source. The management structure comes from documents describing organization and responsibility, accident history and recurrence prevention from incident records, activities and investment from a full year of tallies. The data usually sits in several departments, so collecting it is where the time goes.

Missing the duty carries an administrative fine of up to KRW 10 million. Disclosure filings are also public, so gaps and thin content are visible exactly as filed.

What three weeks is enough for

• Document the safety and health organization chart, responsible officers, and assigned teams.
• Collect occupational accident records in one place and check for gaps.
• Gather this year's training and inspection records and put the plan for the remaining months in writing. Records of sharing risk assessment results, a statutory duty since June 1, also feed the activities item.
• Tally the safety and health budget and spending separately from other costs.
• If accidents have occurred, document the cause and the recurrence prevention measures for each one.
• Recheck the filing method and format against the finalized rules before the start date.

Even if the five items cannot all be completed in three weeks, deciding where each item's data lives and who owns it is realistic, and that map carries straight into next year's filing. The text of Article 10-2 and its subordinate legislation is available in the amendment list for the Occupational Safety and Health Act at the Korean Law Information Center (law.go.kr).

The full-year schedule is in guide 1 of 4, 2026 Korean Workplace Safety Law Changes: Dates and Checklist, and preparation for the June changes is in guide 2 of 4, Korean Risk Assessment in 5 Steps: 2026 Practical Guide.

Items like accident history and activity records can only be written from records that already exist. On the equipment side, continuous monitoring of sound, vibration, and environmental signals with a tool such as XyloZero keeps those records accumulating day to day.
