MOEL Identifies 32 High-Risk Substances with Mandatory Workplace Safety Controls

Key Risk Findings and Substance Classification

Of the 72 substances evaluated, 32 chemicals have been classified as high-risk, based on their hazardous properties, including:

• Acute toxicity
• Reproductive toxicity
• Skin corrosion and irritation

One highlighted substance is 2-methylpiperidine, recognized for its corrosive and toxic effects.

Mandatory Workplace Safety Measures

Employers handling any of the 32 high-risk substances must implement the following compulsory safety controls:

• Provision and mandatory use of personal protective equipment (PPE)
• Installation of local exhaust ventilation systems
• Clear workplace display of hazard labels and Material Safety Data Sheets (MSDS)
• Specialized training for all workers interacting with these chemicals

Safety Communication and Training Requirements

To strengthen compliance and hazard awareness:

• MSDS and hazard communication labels must be visibly posted on all containers and packaging
• Employers are obligated to train employees on handling procedures and emergency response protocols
• Training programs must reflect current legal obligations and updated hazard data

Multilingual Support for Foreign Workers

Recognizing the diversity of South Korea’s industrial workforce, MOEL, in cooperation with the Occupational Safety and Health Corporation, has released chemical safety materials in 17 languages. These include translations of:

• Hazard symbols and pictograms
• PPE usage guides
• Chemical handling procedures

This initiative aims to minimize risks for non-Korean-speaking workers and promote inclusive workplace safety.

Advancing Chemical Safety and Occupational Health

South Korea’s latest chemical safety announcement underscores its commitment to protecting workers from chemical hazards and promoting responsible industrial practices. The integration of multilingual resources and mandatory risk controls reflects a comprehensive approach to occupational health management.
