Math
- Incidence rate = cases × 200,000 ÷ hours worked
- Ohm's law: V = I × R; power P = V × I
- Ventilation Q = V × A
Programs and concepts
- Hierarchy: elimination, substitution, engineering, administrative, PPE
- ISO 45001 and ANSI Z10 follow plan-do-check-act
- Leading indicators predict; lagging indicators measure past harm
Fire and IH
- Fire tetrahedron: fuel, heat, oxygen, chemical chain reaction
- STEL is a 15-minute limit; ceiling must never be exceeded
- Time, distance and shielding reduce radiation dose
Training and legal
- Kirkpatrick levels: reaction, learning, behavior, results
- OSHA 300 logs are kept five years
- Multi-employer worksites: creating, exposing, correcting, controlling employers
