Risk Assessment Excel Template (3 Industries) — Construction, Manufacturing & Service

Under Korean occupational safety law, every workplace must conduct risk assessments — but a generic form rarely captures industry-specific hazards effectively. This template provides pre-loaded hazards for construction, manufacturing, and service sectors, with automatic risk-level scoring via a frequency × severity matrix.

Key Features

⚠️ Pre-Loaded Hazards for 3 Industries

Industry	Sample Hazards
Construction	Falls, falling objects, electrocution, collapse, heavy equipment entrapment, confined space
Manufacturing	Entanglement, cuts, fire/explosion, noise, chemical exposure, slips
Service	Musculoskeletal disorders, slips/trips, electrical shock, VDT syndrome, workplace violence

📊 Frequency × Severity Risk Matrix

• Frequency (likelihood): 5 levels from Rare (1) to Frequent (5)
• Severity (consequence): 5 levels from Minor (1) to Fatal (5)
• Risk score = Frequency × Severity auto-calculated
• Auto-classified: Acceptable (1–4) / Caution (5–9) / Significant (10–15) / Critical (16–25)
• Color-coded by level (green / yellow / orange / red)

🛡️ Reduction Measures & Residual Risk

• Document controls: engineering, administrative, PPE
• Re-assess residual frequency × severity after controls
• Auto-determine if residual risk is acceptable

📋 Assessment History

• Initial assessment date, reassessment date, assessor
• Change triggers (process change, incident, regulatory update)

How to Use

Step 1: Select Industry and Register Processes

Choose your industry in the ‘Settings’ sheet and list key processes. Representative hazards auto-populate.

Step 2: Assess Risks

In the industry-specific sheet, enter frequency and severity scores. Risk levels calculate automatically.

Step 3: Plan Reduction Measures

For risks rated ‘Significant’ or above, document controls and reassess residual risk.

Step 4: Review Dashboard

Check risk distribution by process and level on the ‘Dashboard’ sheet.

Tips

Track Ad-Hoc Assessment Triggers

Korean OSH law requires reassessment after incidents, process changes, or regulatory updates. Log triggers in the history sheet for easy compliance tracking.

Document Worker Participation

Worker involvement in risk assessment is a legal requirement. Note participating workers and whether their input was reflected.

Best Practices

Conduct Risk Assessments with Front-Line Workers, Not Just Managers

The most accurate hazard identification comes from workers who perform the tasks daily. Schedule 30-minute walkthroughs with team leads from each process area and have them describe near-misses they have witnessed. Enter these observations directly into the industry-specific sheet during the walkthrough. Assessments done purely from a desk consistently underestimate frequency scores because managers are not exposed to the same conditions as floor workers.

Prioritize Residual Risk Reassessment for “Significant” Items Within 30 Days

After documenting reduction measures for risks scored 10 or above, do not wait until the next scheduled review to check if controls are working. Set a 30-day follow-up specifically for high-scoring items. Enter the reassessment date in the history sheet and verify that the implemented controls actually reduced the frequency or severity as expected. If residual risk remains above 9 after controls, escalate to engineering controls or process redesign rather than adding more administrative measures.

Use the Hierarchy of Controls When Selecting Reduction Measures

Always evaluate controls in this order: elimination, substitution, engineering controls, administrative controls, and PPE as a last resort. A common mistake is jumping straight to PPE (safety glasses, gloves) because it is the cheapest option. Document which level of the hierarchy each control belongs to in the reduction measures column. Auditors specifically check whether higher-level controls were considered before defaulting to PPE.

Photograph Hazard Conditions and Link to Assessment Records

When identifying a hazard during a site walkthrough, take a photo and note the file name in the assessment sheet’s notes column. Visual evidence makes reassessment faster because you can compare before-and-after conditions without relying on memory. It also provides documentation for KOSHA audits and insurance claims if an incident occurs.

FAQ

Are workplaces with fewer than 5 employees exempt?

No. All workplaces must conduct risk assessments under Korean law, though smaller businesses may use simplified methods.

Is this compatible with KRAS?

This template uses a frequency × severity matrix similar to KOSHA’s KRAS framework. Items can be added or modified for alignment.

Do results need to be submitted to KOSHA?

Submission is optional but enables recognition benefits including accident prevention facility support.

How often should risk assessments be updated?

Korean OSH law requires an initial assessment plus reassessment whenever there is a change in work processes, equipment, raw materials, or after a workplace accident. Beyond legal requirements, best practice is to conduct a full review annually and spot-check high-risk processes quarterly. The Assessment History sheet tracks reassessment dates and triggers so you can demonstrate a consistent review cycle during audits.

Can I use this template for office environments?

Yes. While the pre-loaded hazards focus on construction, manufacturing, and service sectors, office environments fall under the service category. Common office hazards include VDT syndrome from prolonged screen use, musculoskeletal disorders from poor ergonomics, slips on wet floors, electrical hazards from overloaded outlets, and psychosocial risks like excessive overtime. Add office-specific items to the service industry sheet and adjust frequency and severity scores to reflect the lower but still real risk levels present in office settings.
