- Research project accounts for 10% of the final mark.
- Mid-term exam holds a weight of 30%.
- Final exam represents 40% of the total assessment.
- Overall course total equals 100%.
Responsibility for Health and Safety
- Every individual has the right to a safe work environment with controlled health risks.
- Worker behavior plays a critical role in maintaining safety but is not sufficient on its own.
- A designated safety director or industrial hygienist is typically responsible for setting safety protocols.
- The course aims to support safety managers in detecting and addressing workplace hazards.
Safety Versus Health
- Safety focuses on immediate hazards (acute effects) such as physical injuries.
- Health addresses long-term effects (chronic effects) from prolonged exposure to mild hazards.
- Industrial hygienists specialize in health hazards with scientific and technical expertise.
- Safety specialists leverage practical job experience rather than advanced scientific tools.
- Delayed health fatalities often go unrecorded in statistics, complicating hazard assessment.
Ergonomics
- Integrates various disciplines: sociology, psychology, anatomy, physiology, and more.
- Aims to improve human health, safety, and performance in the workplace.
- Ergonomists contribute to teams with engineers and medical personnel to enhance workplace design and job processes.
- Emphasizes injury prevention by addressing ergonomic hazards systematically.
Ergonomic Hazard Management
- Implements a triad of recognition, evaluation, and control to identify and mitigate ergonomic risks.
- Engineering controls involve redesigning workstations for ergonomic compliance.
- Comprehensive training for workers is critical when workplace or equipment changes occur, ensuring documentation of training sessions.
Employer Responsibilities
- Employers must utilize engineering practices to eliminate or reduce hazards.
- Provide appropriate personal protective equipment (PPE) when risks cannot be completely removed.
- PPE should be a last resort after all other control measures have been explored.
Hearing Protection
- Selecting noise protection primarily depends on its effectiveness to reduce decibel exposure.
- Worker comfort is crucial; uncomfortable protection leads to non-compliance and increased risk.
- Common materials like cotton provide minimal noise protection, whereas Swedish wool offers better attenuation when properly sealed.
Electrical Safety Principles
- Human skin acts as an insulator; dry skin can have resistance up to 100,000 ohms.
- Moisture drastically reduces skin resistance, increasing the risk of dangerous electrical currents.
- Grounding is vital for electrical circuits to function properly; it ensures a complete loop for current flow.
Understanding Wiring Circuits
- A typical 110-volt circuit contains hot, neutral, and ground wires.
- The hot wire provides power, while the neutral wire completes the electrical circuit.
- The ground wire offers safety by preventing electrical shocks and faults.
