Chapter 3: Hazard Recognition, Assessment, and Control
Chapter 3: Hazard Recognition, Assessment, and Control
This is a narrative outline of Chapter 3 (Or Module 3), which focuses on the anticipation, identification, assessment, and control of physical hazards in the workplace. Physical hazards—such as noise, vibration, radiation, and temperature extremes—are environmental factors that can harm workers without direct contact. Understanding these hazards requires recognizing root causes (systemic issues like poor design) and proximate causes (immediate triggers like faulty equipment) to guide effective control measures.
Key topics on this Module include techniques for controlling workplace noise through engineering and administrative measures (strategies), as well as personal protective equipment (PPE). Vibration hazards are also examined for their musculoskeletal disorders (MSDs) and circulatory impacts, with solutions like equipment redesign and safe work practices (administrative controls). Radiation, both ionizing and non-ionizing, is a physical hazard which is addressed through prevention strategies such as shielding and exposure duration minimization. The chapter also covers prevention of heat and cold stress through acclimatization, monitoring, and protective gear (PPE).
Finally, the chapter explores ergonomic hazards and related principles, emphasizing proper work design to reduce long-term health effects from repetitive tasks and awkward postures. It concludes by noting that, by applying the processes or framework of anticipation, identification, assessment, and control, learners will be prepared to address a wide range of physical hazards to safeguard worker health and safety.
