Question 897 Deck Safety

The correct answer is D) male coupling at the nozzle end and a female coupling at the hydrant end. This is the standard configuration for fire hoses used by the US Coast Guard and other fire departments. The male coupling at the nozzle end allows the hose to be easily connected to the fire nozzle, while the female coupling at the hydrant end allows the hose to be securely attached to the fire hydrant or pumping equipment. The other options are incorrect because they do not match the standard fire hose coupling configuration. Having female couplings at both ends (option B) or male couplings at both ends (option C) would make it difficult to properly connect the hose to the necessary equipment.
