Rooftop Install Safety — Harness/Anchor/Fall Prevention
Likely causes
Korean OSHA + KOSHA Guide for rooftop installation
Check: Rooftop work ≥2m height = fall prevention required (OSHA Rules §42). 2024 stats: 35% of fatal falls in construction; HVAC techs rank 5th in incident frequency. Required gear: ① Harness (Class 2, 5-point, CE). ② Lanyard (8mm wire rope). ③ Embedded anchor (M10, ≥5kN load, KS B 0801). ④ Shoes (slip-resistant, EN ISO 20345). ⑤ Helmet (Class 1, absorbs 1kg shock). Pre-work: edge guardrail (1.5m, KOSHA standard).
What to do: Pre-work: ① harness expiry (5 yr mfg, 6 mo inspection). ② lifeline weight cert (5000N/unit, annual cert, KCs). ③ anchor pull test all 4 sides (mandatory before rooftop work). ④ weather (wind ≥10m/s, rain → stop). ⑤ 2-person team (no solo). Accident: call 119, industrial injury insurance (<50 employees mandatory, report within 14 days).
Rooftop quotes itemize safety cost (harness, insurance, 2-person = 1.5x normal). User may complain 'expensive' but it's standard (Korea HVAC Assoc guide). Solo work = injury, legal liability, license suspension. Single fatal accident ≈ ₩100M compensation; tech's family can't recover. Day-rate rooftop insurance available (~₩10k).
