Which material is NOT typically used to treat wood shores to enhance fire safety?

The correct answer is based on the understanding of how different materials interact with fire safety measures. Fire retardant paint and fire resistant chemicals are specifically designed to enhance fire safety by either slowing the spread of flames or providing a barrier to ignition. These treatments are applied to wood shores to protect them from fire damage, which is essential in areas where fire exposure is a risk.

On the other hand, water repellant fabric does not provide any fire-resistant properties; instead, its primary function is to protect against moisture. Although moisture control is important for wood preservation and can help in reducing decay, it does not contribute to fire safety in the same way that fire retardant options do. Therefore, water repellant fabric is not typically used in the context of treating wood shores for fire safety, making it the correct answer to the question.
