Study Notes
Worker Fatalities and Incidence Rates
- Worker fatalities are recorded more consistently than injuries and illnesses, making them a reliable statistic for trend analysis.
- Frequency and severity are traditional measures in workplace safety, where frequency measures cases per work hours, and severity measures total lost workdays.
Incidence Rate Calculation
- First aid is not classified as medical treatment; all injuries must be recorded regardless of treatment.
- Incidence rate calculation involves dividing the number of injuries by total hours worked, multiplied by a standard factor for clarity.
- A full-time worker typically works approximately 2,000 hours per year (40 hours/week for 50 weeks).
Types of Incidence Rates
- Total-Recordable-Cases (TRC) include all injuries and illnesses without fatalities.
- Lost-WorkDay-Cases Incidence Rate (LWDI) counts injuries resulting in lost workdays, excluding illnesses and fatalities.
- Days Away, Restricted, or Transferred Rate (DART) includes cases involving time away, restricted activities, and job transfers.
Recordkeeping Requirements
- OSHA mandates the completion of Form 301 within seven calendar days following a recordable work-related injury or illness.
- Records must be kept for five years according to Public Law and OSHA regulations.
Ergonomics Definition and Relevance
- Ergonomics, derived from Greek, studies work principles and aims to optimize human well-being and performance in systems.
- Knowledge of physical and psychological human capabilities aids in designing workplaces to reduce injury risks.
History and Development of Ergonomics
- Ergonomic principles date back to ancient civilizations' tool design to alleviate workload.
- The Industrial Revolution prompted improvements in machine design, aligning with ergonomic practices.
Ergonomics and Safety Management
- Ergonomics safety focuses on aligning products and methods with workers' capabilities to ensure a safer environment.
- Employing ergonomic principles significantly enhances human performance and safety in the workplace.
Employee Fitness for Safety Roles
- Workers should be medically screened for conditions that may impair safety performance, particularly in demanding roles like firefighting.
- A physician's certification is essential for volunteers in potentially hazardous positions.
Firefighter Training Needs
- Fire brigade training should occur quarterly for structural firefighting and annually for other members.
- Regular inspections of firefighting equipment, including monthly checks on extinguishers, are crucial for maintaining safety.
Fire Extinguishers and Their Importance
- Fire extinguishers effectively control localized fires and should be appropriate for various fire classes.
- Proper care and understanding of extinguishing agents, such as dry chemicals, are necessary to prevent caking and ensure effectiveness.
Electrocution Hazards Awareness
- Ordinary 110-volt circuits can be lethal, dispelling the myth that they are safe due to common exposure without serious injury.
- Risk factors for electrocution include wet conditions and the body’s contact points, highlighting the need for caution during electrical work.
