CM11.1-6 | Occupational Health — Assignment

Grading Rubric — Occupational Health Case Study Rubric

Criterion	Points	Full-marks descriptor
CM11.1 + CM11.3: Occupational diagnosis, exposure-disease linkage, and hazard classification	5 pts	Exceeds: Names silicosis + silicotuberculosis with precise pathophysiological link (crystalline silica → macrophage activation → fibrosis → TB susceptibility); classifies all 5 hazard categories with appropriate workplace examples; cites specific silica TLV (respirable ≤0.05 mg/m³ for quartz).
CM11.3: Hierarchy of controls applied to silica dust hazard	5 pts	Exceeds: Applies all 5 tiers of the hierarchy with specific, technically correct examples (e.g., wet drilling for engineering; silica-free abrasive substitution; half-face respirator FFP3 as PPE); correctly distinguishes primary vs secondary prevention.
CM11.2: ESI entitlements — coverage criteria, benefits, and calculations	5 pts	Exceeds: Correctly confirms ESI coverage (wage ₹18,500 < ₹21,000 ceiling); accurately calculates sickness benefit (₹18,500÷30×0.70 ≈ ₹432/day); explains permanent partial disablement benefit formula; cites specific documentation required (Form 9 / medical certificate).
CM11.6: Factory occupational health programme — surveillance, statutory requirements, evaluation	5 pts	Exceeds: Lists all applicable Factories Act requirements for 650 workers (canteen ≥250, welfare officer ≥500, OHC per state rules); designs surveillance with correct periodicity (pre-placement + annual CXR/spirometry for silica workers); proposes ≥2 process + ≥2 outcome indicators with operational definitions.
