- 6.1: Definition
- This page clarifies the difference between "Caught" and "Struck" workplace injury events, with "Caught" referring to crushing injuries and "Struck" to impact injuries. It provides examples like cave-ins and machinery entrapment and identifies contributing factors such as unguarded machinery. Despite a decrease in fatalities from these hazards in construction, they remain significant risks, underscoring the importance of safety awareness and measures at job sites.
- 6.2: Caught In or Between Descriptions
- This page highlights the hazards of being buried in trenches and excavations, focusing on cave-ins, hazardous atmospheres, and risks from scaffolds. It details fatal incidents involving workers killed by cave-ins in unprotected trenches and injuries from being pinned between equipment. The importance of implementing safety precautions to avoid these incidents is strongly emphasized throughout the discussion.
- 6.3: Safegaurds
- This page highlights essential safety practices in machinery operation and excavation work. It stresses the necessity of wearing personal protection equipment, keeping safety guards intact, and securing machinery before maintenance. Workers are advised to avoid loose clothing and maintain awareness of their surroundings to prevent accidents. In excavation, proper protective measures, such as trench boxes and safe entry points like ladders, are crucial for worker safety.
- 6.4: What is my employer required to do to protect workers from caught-in or –between hazards?
- This page details safety measures and responsibilities for employers in construction, focusing on preventing accidents with power tools and heavy equipment. It outlines specific requirements such as machinery guards, equipment security, and worker safety during trenching and scaffold use. Employers must appoint a competent person for safety oversight and provide training on hazard recognition and equipment operation, with an emphasis on OSHA compliance.
- 6.5: Review Questions
- This page emphasizes construction and excavation safety hazards, particularly "struck-by" and "caught-in or -between" incidents. It discusses the responsibilities of competent persons per OSHA standards, the necessity of protective measures in trenches, and compliance with safety protocols like lockout/tagout. Additionally, it features assessment questions to reinforce understanding and underscores the importance of training and adherence to safety standards to prevent injuries.
