2026 Korean Workplace Safety Law Changes: Dates and Checklist
Workplace Safety Field Guide 1 of 4: 2026 Korean law changes
Korea's 2026 workplace safety calendar has three dates on it: June 1, June 26, and August 1. The first two have already passed, so worker participation duties in risk assessment and the wider safety inspection net are in force right now. The disclosure duty is the one you can still get ahead of. Each date needs its own owner and its own evidence, and treating the three as one deadline is how items get missed.
This guide was reviewed against laws in force or promulgated as of July 12, 2026. Confirm applicability for each workplace against the current statutory text and guidance from the responsible authority.
What changed and when
| Effective date | Change | Action to take now |
|---|---|---|
| June 1, 2026 | Worker participation and communication duties became part of the statutory risk assessment process. | Record participants, the assessment process, and how results were shared. |
| June 26, 2026 | Mixers, crushers, and grinders entered the mandatory safety inspection regime. | Match each machine installation date to its first inspection deadline. |
| August 1, 2026 | Safety and health disclosure begins for entities covered by the Act. | Confirm coverage and collect evidence for the five disclosure areas. |
| From January 1, 2027 | Risk assessment administrative fines phase in by workplace size. | Distinguish the 2027 and 2028 start dates. |

June 1: the form alone no longer closes an assessment
A completed risk assessment form used to be the end of the paper trail. Since June 1 it is not. Article 36 of the Occupational Safety and Health Act requires worker participation, requires participation by a worker representative when requested, and requires results to be communicated through training, briefings, postings, written material, or electronic means.
The weak point is usually the connections between records. A sign-off line survives, but nothing ties it to the walkthrough that found the hazard or to the notice that reached the crew. Useful evidence links the people who identified hazards, the person who confirmed each control, the completion record, and the communication record.
The fines are already defined. Skipping the risk assessment can carry an administrative fine of up to KRW 10 million; failing on participation or communication, up to KRW 5 million; recordkeeping violations, up to KRW 3 million. The provisions phase in on January 1, 2027 and January 1, 2028 by workplace size.
June 26: one shared inspection date will not fit every machine
Mixers, crushers, and grinders became subject to mandatory safety inspection on June 26. The general cycle is a first inspection within three years of installation and one every two years after that. Machines installed before the rule took effect follow transitional schedules, so each machine carries its own deadline. Putting the whole fleet on a single date hides exactly the differences that matter.
A list of machine names cannot surface those deadlines. A working register holds the serial number, installation date, work area, latest internal check, applicable transition rule, and next statutory deadline, which makes the machines closest to their dates easy to pull up. Keep statutory inspection records separate from routine internal maintenance.
August 1: five disclosure areas, not one accident count
When disclosure preparation starts, the accident count is usually the first file anyone opens. It feeds one of five areas: the safety and health management system, industrial accident history, prior-year activity and current-year plans, safety and health investment, and recurrence-prevention measures. The duty covers employers above a size set by presidential decree and public entities specified by law.
The other four areas draw on different records. Responsibility charts, plan-versus-execution records, investment evidence, and corrective actions need a consistent reporting date and scope before the areas line up. Confirm coverage against the latest decree text, not a press-release summary.
Coverage tests and a preparation sequence for each area are in Safety and health disclosure starts August 1: what to prepare.
The short list, grouped by date
- June 1: a defined participation step for every assessment, plus a record of how results were communicated through training, posting, writing, or electronic means.
- June 26: per-machine installation dates and inspection deadlines, with statutory and internal records kept apart.
- August 1: a coverage check against the current decree, and an owner, reporting date, and evidence location for each of the five areas.
Reviewing internal procedures against the amended law deserves a recurring slot regardless of date. The same records answer an inspector, feed the August disclosure, and start the next risk assessment.

Keeping evidence current after the fixes
Hazards do not stay fixed once corrected, and follow-up reviews are easier with a continuous record behind them. XyloZero facility monitoring captures acoustic, vibration, and environmental condition signals at the edge and flags anomalies, which gives those reviews something concrete to check against. None of that replaces worker participation, mandatory inspection, disclosure, or any other legal duty.
