Construction sites involve numerous hazards such as falling objects, electrical risks, chemical exposure, excessive noise, dust, machinery accidents, and work at heights. Even with proper engineering controls and safe work practices, workers may still face certain unavoidable risks. Personal Protective Equipment (PPE) acts as the last line of defence by protecting workers from injuries and reducing the severity of accidents. PPE includes specially designed clothing, equipment, and devices worn by workers to protect different parts of the body from workplace hazards. ## Importance of Personal Protective Equipment (PPE) PPE plays a crucial role in maintaining safety at construction sites. It helps minimize exposure to hazards and protects workers from immediate injuries as well as long-term health problems. Proper selection, regular inspection, and correct use of PPE are essential for its effectiveness. The major roles of PPE include: * Preventing injuries caused by workplace hazards. * Reducing the severity of accidents. * Protecting workers from exposure to harmful substances. * Improving safety awareness among workers. * Supporting safe work practices in hazardous environments. However, PPE should not be considered a substitute for proper safety management. It must be used along with hazard control measures, training, and safe working procedures. # Types of Personal Protective Equipment and Their Roles ## 1.
