Final answer:

To identify static 1 hazards, one must understand thermal hazard, shock hazard, and short circuit. A thermal hazard results from excessive current causing overheating, while a shock hazard involves current passing through a person. A short circuit could lead to a thermal hazard, not a shock hazard, and the severity of a shock depends on multiple factors, not just voltage.

Step-by-step explanation:

It refers to identifying static 1 hazards in a circuit with inputs A, B, C, and D. The subject at hand involves understanding electric circuits and the safety hazards associated with them. First, let's define the relevant hazards:

  • Thermal hazard: This occurs when excessive current leads to overheating, which in extreme cases can cause fires. It is a result of electric energy being converted into thermal energy too quickly for it to be safely dissipated.
  • Shock hazard: This takes place when electric current passes through a person, potentially causing anything from mild discomfort to life-threatening effects.
  • Short circuit: This is a low-resistance path between terminals of a voltage source, leading to a sudden surge in current which can result in a thermal hazard but not specifically a shock hazard.

A short circuit is not considered a shock hazard because it typically does not involve direct human contact with the current. Instead, it is a hazard due to the potential for overheating and fire.
