🥬 Market Greens & Produce: Ergonomics & Techniques
Field cutting ergonomics, knife safety, wash-station posture, and cold-water protection standards.
1. Primary Physical Risk Factors
- Continuous Squatting: Harvesting ground-level crops causes knee joint compression and lower back tightness.
- Repetitive Knife Motions: Sustained wrist deviation when using harvesting knives or sickles.
- Cold-Water Immersion Fatigue: Hand stiffness and circulatory constriction during cold-water field washing.
2. Biomechanical & Ergonomic Standards
Keep wrists straight when wielding harvesting knives; allow arm and shoulder motion to push the blade. Utilize rolling harvest carts or straddle benches to maintain supported postures.
3. Step-by-Step Harvest Protocol
- Grasp-and-Slice: Secure the top half of the greens bundle lightly; slice cleanly 1/2-inch above soil line in one motion.
- Field Trim: Remove yellowing or damaged outer leaves immediately at the bed.
- Standardized Bin Packing: Layer greens gently in uniform grid patterns to avoid bruising.
