What is vessel maintenance?

Maintenance is one thing that keeps any mechanical equipment or machinery going. Weather it is a small machine or a large structure, efficient maintenance can help with prolonged life and favorable outcome. On a ship, maintenance is one thing that keeps machinery up to date and is smooth running condition.

Which of the following is an accurate statement about the maintenance of back fire flame control device arrestors?

Which of the following is an accurate statement about the maintenance of Back-Fire Flame Control Device arrestors? Arrestors should be inspected on a monthly basis. What type of vessel is required to have a fire extinguisher?

What is every vessel operator required to do?

Every operator must keep a proper lookout, using both sight and hearing, at all times. Watch and listen for other vessels, radio communications, navigational hazards, and others involved in water activities. Maintain a safe speed.

When preparing your vessel for cold weather use antifreeze that contains ethylene glycol?

If you must use chemical products on your vessel, minimize their use while on the water. Before the first use of your vessel in the spring, drain the antifreeze into a container and properly dispose of it on shore. Never use antifreeze containing ethylene glycol. When fueling, don’t top off the tank.

What is true about a carburetor backfire flame arrestor?

Because boat engines may backfire, all powerboats (except outboards) that are fueled with gasoline must have an approved backfire flame arrestor on each carburetor. Backfire flame arrestors are designed to prevent the ignition of gasoline vapors in case the engine backfires.

Which of the following is recommended maintenance for an inboard boat?

Change oil every 100 hours

Most inboard boats will require regular oil changes. Consult your user manual to find out how regular oil changes should be, but a decent guideline to follow would be to do so every 100 hours of engine usage.

What is propylene glycol coolant?

Propylene glycol is considerably less toxic than ethylene glycol and may be labeled as “non-toxic antifreeze“. It is used as antifreeze where ethylene glycol would be inappropriate, such as in food-processing systems or in water pipes in homes where incidental ingestion may be possible.

What is propylene glycol antifreeze?

Propylene glycol is a substance commonly used as a food additive or ingredient in many cosmetic and hygiene products. … However, it has become controversial since it is also an ingredient in antifreeze. This had led to health concerns about possible toxic effects from eating foods that contain it.

What is one part of a regular pleasure craft and engine maintenance program?

Follow a regular maintenance program. Keep your engine clean and tuned properly. … Inspect the engine for anything that shows signs of wear or requires tightening, such as hoses, belts, and bolts. Make sure everything is fitted properly, including the engine cover.

Is glycol ethylene or propylene?

Ethylene glycol is the predominant fluid used for automotive antifreeze formulations. Propylene glycol is used in food and pharmaceutical applications, and HVAC systems in schools, homes, and businesses – anywhere there is a risk of human or animal exposure.

Which is better ethylene or propylene?

The difference between Propylene Glycol and Ethylene Glycol in antifreeze comes down to both toxicity levels and efficiency of performance. Ethylene glycol possess far superior heat transfer properties whereas Propylene Glycol carries a very low toxicity.

What is antifreeze compound?

antifreeze, any substance that lowers the freezing point of water, protecting a system from the ill effects of ice formation. Antifreezes, such as ethylene glycol or propylene glycol, commonly added to water in automobile cooling systems prevent damage to radiators.

What color is eg coolant?

green
Inorganic Acid Technology (IAT) is the chemical composition for the traditional antifreezes that are green in color. An IAT can be used with either ethylene glycol (EG) or propylene glycol (PG).

Is glycol a refrigerant?

Glycol is sometimes called antifreeze or a coolant. Though it acts similarly to a refrigerant, and someone may refer to glycol as a refrigerant, this statement is incorrect. Glycol cools solely through heat transfer in an exchanger; whereas, refrigerant uses an evaporation-condensation cycle to remove heat.

Is propylene glycol a refrigerant?

Propylene glycol is commonly used in food Industry or in industrial refrigeration systems where people may come into contact with fluid. Propylene glycol can also become more viscous than ethylene, even slightly affecting the heat exchange rate when used at very low temperatures.

Can coolant red?

What colors does coolant come in? Variations of coolant/antifreeze can come in; pink, red, orange, blue, green, and yellow. … The different colors can mean different properties of the liquid.

What is blue coolant?

A blue engine coolant temperature light only indicates one thing: that your coolant, or antifreeze, is too cold. In fact, the temperature is so low that it is possible for your radiator to get too cold, thus resulting in your engine freezing up and not being able to start.

Why is my coolant red?

There are standard anti-freezes that are red and cars that have Dexcool® will be labeled as such. Another myth is that Dexcool® is not glycol based. … Both ethylene glycol (EG) and propylene glycol (PG) are used as the antifreeze base. From here the additional additives and inhibitors are added.
