OSHA Fatal Four | Module 6 | Struck By and Caught in Between Hazards | OSHA 10 Study Guide

Summary

Module 6 of the safety course focuses on 'struck by' and 'caught in between' hazards in construction. It educates on the dangers workers face, such as electrocution and being struck by or caught in heavy machinery. The module offers practical safety measures like using vehicle backup alarms, chalk lines for vehicle rolloffs, and proper shoring techniques to prevent cave-ins. It also emphasizes the importance of safety gear like toe boards and the significance of training in hazard identification and emergency procedures to ensure a secure work environment.

Takeaways

• 🔌 Electrical safety is crucial as electrocution accounts for 12% of workplace deaths and affects young workers significantly.
• 🚨 Module 6 focuses on 'struck by' and 'caught in between' hazards in construction, emphasizing the importance of safety measures.
• 🚜 Audible backup alarms on heavy construction vehicles are essential for alerting workers to potential dangers.
• 🚧 Chalk lines can prevent vehicle rolloffs on inclines, highlighting the role of simple tools in enhancing safety.
• 🏗 Excavation work is a major hotspot for 'caught in between' hazards, with many citations tied to these operations.
• 🚧 Limited access zones around masonry wall construction ensure only essential employees have access, reducing risks.
• 🔢 PSI (pressure per square inch) is a vital measure for compressed air used on construction sites.
• 🏗 Shoring systems like metal hydraulic or timber are crucial defenses against cave-ins during excavations.
• 🛠 Toe boards act as silent guardians along scaffold platforms, preventing tools and objects from falling and causing harm.
• 🚧 Safety rules, such as vehicle backup alarms, strategic flagging, and clear zones around vehicles, are vital for preventing 'struck by' incidents.
• ⚠️ Regular inspections of tools, machinery, and equipment, along with clear communication, are key to maintaining a safe work environment.

Q & A

What is the significance of electrical safety in the workplace as mentioned in module 5?

Electrical safety is crucial as it accounts for 12% of workplace deaths, and about 10 individuals endure electrical burns daily.

What does module 6 focus on in terms of construction hazards?

Module 6 focuses on 'struck by' and 'caught in between' hazards in construction.

What are some key operations prone to struck by and caught in between hazards?

Operations such as excavation work, masonry wall construction, and the use of heavy construction vehicles are prone to these hazards.

What is the role of audible backup alarms in construction safety?

Audible backup alarms are essential on heavy construction vehicles to alert nearby workers to potential danger when a vehicle reverses.

Why are chalk lines important in preventing vehicle rolloffs on inclines during excavation work?

Chalk lines serve as a visual barrier to prevent vehicles from rolling off inclines, thus enhancing safety during excavation work.

What does PSI stand for in the context of compressed air used on construction sites?

PSI stands for 'pounds per square inch', a vital measure for the pressure of compressed air used on construction sites.

What are some safety measures to prevent 'caught in between' hazards during excavation operations?

Safety measures include using shoring systems like metal hydraulic or timber shoring, toe boards, and maintaining a safe distance from the edges of trenches.

How can toe boards be described in terms of their function on scaffold platforms?

Toe boards act as silent guardians along scaffold platforms, preventing tools and objects from falling and causing harm to workers below.

What are some safety controls mentioned for protecting workers from struck by hazards?

Safety controls include using vehicle backup alarms, positioning flaggers, keeping non-essential workers clear of vehicle zones, and using barriers and warning signs.

What is the importance of inspecting cranes and hoists before use?

Inspecting cranes and hoists before every use is crucial to ensure they are in good working condition, preventing accidents and ensuring safety.

What is the significance of the statistics mentioned regarding struck by incidents in 2020?

The statistics highlight the severity of struck by incidents, with 150 lives lost and 14,000 people affected, emphasizing the need for improved safety measures and awareness.
