What Is Industrial Accident (산재)? A Complete Guide for Foreign Workers in Korea

What Does "산재" (Industrial Accident) Actually Mean?

"산재" is an abbreviation of 산업재해 (industrial accident, 産業災害). Legally, it is defined in Article 5, Item 1 of the Industrial Accident Compensation Insurance Act (산업재해보상보험법 제5조 제1호) as follows:

"The death, injury, or disease of a worker caused by structures, equipment, raw materials, gas, steam, dust, or other substances related to work, or by work or other duties."

In plain terms, 산재refers to any situation in which a worker is injured, becomes ill, or dies as a result of their work.

Note for foreign workers: The statutory protections described in this article apply regardless of nationality. However, the specific terms of your employment contract may differ from the statutory minimum — always check both.


Three Types of Work-Related Injury (업무상 재해)

Article 37 of the Industrial Accident Compensation Insurance Act (산업재해보상보험법 제37조) classifies work-related injuries into three main categories.

1. Work-Related Accident (업무상 사고)

Accidents caused by machinery or equipment malfunction, falls, collisions, or similar events during work. This is the most typical type of industrial accident. If a causal relationship is recognized — i.e., the accident occurred during the performance of work duties — it is processed as an industrial accident.

2. Occupational Disease (업무상 질병)

This covers occupational diseases arising from prolonged exposure to hazardous environments, such as noise-induced hearing loss, pneumoconiosis, musculoskeletal disorders, and cardiovascular or cerebrovascular diseases caused by overwork. The key standard is whether there is a substantial causal relationship (상당인과관계) between the work and the disease. The Supreme Court has held that this causal relationship does not need to be proven by strict medical or natural-scientific evidence, and may be inferred from all relevant circumstances (Supreme Court Decision 2017다218246, etc.).

3. Commuting Accident (출퇴근 재해)

Accidents occurring while commuting by the usual route and method are also recognized as industrial accidents. However, cases involving a significant deviation from the normal route, or the worker's own intentional act or criminal conduct, are excluded.


What Is Industrial Accident Insurance (산재보험)?

Industrial accident insurance is a mandatory social insurance program (의무 가입 사회보험) operated by the state. Any workplace that employs even one worker is automatically covered, regardless of business size or industry. The insurance premium is paid entirely by the employer; workers do not pay any portion of the premium.

The types of benefits paid under industrial accident insurance are as follows:


Difference Between Industrial Accident Insurance and National Health Insurance

Many workers receive treatment under the National Health Insurance (건강보험) instead of filing an industrial accident claim. However, if a work-related injury is processed through National Health Insurance, the National Health Insurance Service (건강보험공단) may exercise its right of indemnity (구상권) against the employer, and the worker will be unable to receive benefits unique to industrial accident insurance, such as the temporary disability benefit and disability benefit. If you are injured at work, it is always advisable to consider filing an industrial accident claim first.


How Do I Start an Industrial Accident Claim?

Submit a medical care benefit application (요양급여 신청서) to a local branch of the Korea Workers' Compensation and Welfare Service (근로복지공단) or online through the Employment and Industrial Accident Insurance Total Service (고용·산재보험 토탈서비스). The agency will conduct an investigation and determine whether the injury qualifies as a work-related injury. If the claim is denied, you may pursue an appeal (심사청구), re-appeal (재심사청구), or administrative litigation (행정소송).


The labor law provisions that apply to a workplace — beyond industrial accident insurance — vary depending on the number of regularly employed workers (상시근로자 수). Use Varo's regularly employed worker count calculator to quickly check which laws apply to your workplace. You can also use the AI search feature to instantly look up any questions you have about industrial accidents.
