Safety Critical Task Analysis (SCTA) Health Check: Tip 5 - Hierarchy of Control

🚫 'Add More Training' Is Not a Strategy Real conversation from an SCTA review: "What's your recommendation here?" "Training and procedure update." "And here?" "Training and procedure update." "And this critical step?" "Training and procedure update." 🚨 This is a red flag that analysis wasn't done properly. Here's the truth: If EVERY recommendation is training/procedures, you're scoring 1/10 on this element. Use the hierarchy of controls: 1️⃣ ELIMINATE: Remove the reliance on human action entirely Example: Stop offloading into multiple tanks, only offload if there is enough room in one tank. 2️⃣ SUBSTITUTE: Change the process Example: Use a less hazardous chemical 3️⃣ ENGINEERING: Physical changes Example: Enlarge tank so orders don't constantly hit high-level alarm 4️⃣ ADMINISTRATIVE: Procedures, training, supervision Example: Checklist, barcode scanning system Training and procedures ARE important, but they should be: ✓ Linked to specific error types (e.g. mistakes) ✓ Combined with higher-level controls ✓ Justified when lower tiers aren't feasible For each recommendation, ask: "Could we reduce reliance on people getting this right?" If no: Explain why. If yes: Do it. "If we're saying this MUST rely on people, we need to explain why that's the case. Otherwise it's open to challenge." - Jamie Henderson What level are YOUR recommendations? You can access the full SCTA Health Check Webinar here: https://the.humanreliabilityacademy.c...
