OSHA 1030: Materials Equipment - Caught-inbetween hazards - trenches, machinery, and pinch points

Caught-in/between hazards — trenches, machinery, and pinch points

What Is It?

Caught-in/between hazards refer to situations where a person can become trapped between two or more objects, such as trenches, machinery, or pinch points, which can cause crushing, pinching, or entrapment injuries.

Misconceptions

1. Caught-in/between hazards only occur in trenches and excavations.
2. Machinery is not a common source of caught-in/between hazards.
3. Pinch points are only a concern for manufacturing and assembly operations.

Common Mistakes

1. Failing to conduct a thorough risk assessment for caught-in/between hazards.
2. Not implementing control measures, such as guardrails or safety nets.
3. Ignoring pinch points and other potential caught-in/between hazards.

The Common Trap

The most common trap is underestimating the severity of caught-in/between hazards and failing to implement adequate control measures.

Terms to Remember

1. Caught-in/between hazard: A situation where a person can become trapped between two or more objects.
2. Trench: A narrow excavation or depression in the ground.
3. Pinch point: A location where two or more objects can come together to cause crushing or pinching injuries.
4. Guardrail: A barrier used to prevent falls or caught-in/between hazards.
5. Safety net: A mesh or net used to catch falling objects or prevent caught-in/between hazards.

Step-by-Step Process

1. Identify potential caught-in/between hazards in the workplace.
2. Conduct a thorough risk assessment to determine the severity of the hazard.
3. Implement control measures, such as guardrails or safety nets.
4. Train employees on the proper use of control measures and emergency procedures.
5. Regularly inspect the workplace to ensure control measures are effective.

Exam Answer Builder

1-mark Question

What is a caught-in/between hazard? A) A fall hazard B) A caught-in/between hazard C) A pinch point D) A trench

Correct answer: B) A caught-in/between hazard

2-mark Question

What is the primary purpose of a guardrail in a trench? A) To prevent falls B) To prevent caught-in/between hazards C) To prevent electrical shock D) To prevent fire hazards

Correct answer: B) To prevent caught-in/between hazards

5-mark Question

Describe a scenario where a caught-in/between hazard could occur in a manufacturing setting. How would you control this hazard?

Correct answer: A caught-in/between hazard could occur when an employee is working near a moving machine part and becomes trapped between the part and a nearby object. To control this hazard, you would implement a guardrail or safety net to prevent the employee from coming into contact with the moving part.

This vs That

Caught-in/between hazards are often confused with fall hazards. However, caught-in/between hazards involve being trapped between two or more objects, while fall hazards involve falling from a height.

Time-Saver Hack

When conducting a risk assessment for caught-in/between hazards, look for areas where objects can come together to cause crushing or pinching injuries. This can help you identify potential caught-in/between hazards and implement control measures.

Mini Scenarios

1. Basic scenario: An employee is working in a trench and becomes trapped between the trench walls. What would you do to control this hazard? Answer: You would implement a guardrail or safety net to prevent the employee from becoming trapped.
2. Applied scenario: A machine part is moving and an employee is working nearby. How would you control the caught-in/between hazard? Answer: You would implement a guardrail or safety net to prevent the employee from coming into contact with the moving part.
3. Tricky scenario: An employee is working in a confined space and becomes trapped between the space walls and a nearby object. What would you do to control this hazard? Answer: You would implement a rescue plan and ensure that the employee has a safe means of escape.
