Study Notes
Course Objectives
- Assist safety and health managers in detecting hazards and determining which are worth correcting.
Safety vs. Health Hazards
- Safety management focuses on acute effects from immediate hazards, while health management deals with chronic effects due to prolonged exposure.
- Examples of safety hazards include machine guarding; health hazards include airborne asbestos and chemicals from welding.
- Occupational health fatalities are likely underreported as they often manifest as long-term conditions not easily linked to specific jobs.
Ergonomics in the Workplace
- Operator-machine system analysis examines the interplay between people, machinery, and the environment to identify ergonomic hazards.
- Job demands should align with human capabilities—key factors include anthropometry (body dimensions) and biomechanics (movement).
Identifying and Correcting Ergonomic Hazards
- General tips for preventing ergonomic hazards include:
- Use carts for transporting loads to limit lifting.
- Label heavy loads with their weight for awareness.
- Use proper lifting techniques to avoid spine injuries.
- Store materials at waist height to minimize injury risk.
Employer Responsibilities
- Employers are obligated to protect workers from hazards using feasible engineering controls and PPE as a last resort.
- Initial and ongoing training must be documented for all employees regarding safety procedures and equipment usage.
Hearing Protection
- Effectiveness in reducing noise levels is crucial when selecting hearing protection, alongside comfort and cost considerations.
- Common materials like cotton balls provide insufficient noise protection, while alternatives like Swedish wool offer better attenuation when sealed properly.
Radiation Safety in Diagnostics
- Employers must ensure occupational radiation doses stay within acceptable limits, provide proper safety equipment, and maintain adequate monitoring.
- Workers need to adhere to safety regulations and effectively use protective gear.
Dose Limits for Occupational Exposure
- Dose limits are established to minimize the risk of radiation-related health issues, particularly cancers and skin damage.
- The sievert is the unit used to quantify ionizing radiation exposure affecting human health.
ALARA Principle
- ALARA (As Low As Reasonably Achievable) emphasizes minimizing radiation exposure risks.
- The hands and eyes are most susceptible to radiation burns, which can occur before symptoms become apparent.
Long-term Effects of Radiation
- Chronic exposure can lead to severe long-term health effects, including cancer, life shortening, and genetic disorders.
- The significance of radiation-induced cancer surpasses that of genetic defects.
Safety Regulations and Practices
- Safety devices should never be bypassed without Radiation Safety Officer approval, and equipment must be operated according to established procedures to prevent injury.
