Keywords

💡Electrical Safety

Electrical safety refers to the practices used to prevent electric shock, electrocution, and electrical fires. In the video, it is mentioned as a critical topic from the previous module, highlighting the dangers of electricity in the workplace, such as electrocution and electrical burns, which are responsible for a significant number of workplace deaths and injuries.

💡Struck By Hazard

A 'struck by' hazard refers to the risk of being hit by moving objects or falling objects in a construction setting. The video emphasizes the importance of identifying and mitigating such hazards, which can include falling tools or being hit by vehicles, to ensure worker safety.

💡Caught In Between Hazards

Caught in between hazards involve the risk of workers being crushed or trapped between objects or materials in the construction environment. The video discusses the need for safety measures to prevent such incidents, which can occur during excavation work or when working near heavy machinery.

💡Audible Backup Alarms

Audible backup alarms are safety devices installed on heavy construction vehicles to alert workers of potential danger when a vehicle is reversing. The script mentions them as essential tools for preventing 'struck by' incidents, emphasizing their role in enhancing safety on construction sites.

💡Excavation

Excavation is the process of digging or removing earth, rock, or other materials from a site. The video points out that excavation work is a major hotspot for 'caught in between' hazards, and it is crucial to implement safety measures such as proper shoring and toe boards to protect workers.
