The heat of the sun on upper ballast tanks, such as in a bulk carrier, may generate carbon monoxide. You can safely enter the space without a breathing apparatus if the oxygen content exceeds 14%. Tank Vessel Safety
D Which statement about entering into a tank which has been sealed for a long time is TRUE? If the oxygen content tests at less than 12% you should wear an approved gas mask. The tank should be tested only once to ensure the oxygen content is at least 14% before entry. The tank need not be tested for oxygen content if it is ventilated for more than 24 hours. The tank must be tested at frequent intervals to ensure that hazardous gasses have not regenerated. Tank Vessel Safety
A You have been carrying a liquid with flammable limits of 1% to 7% mixture with air. If your instructions say that no one shall enter the tank if the vapor concentration is over 15% of the LEL, what is the maximum allowable percentage of vapors for men to enter? 0.15 (%) 0.85 (%) 1.05 (%) 7 (%) Tank Vessel Safety
A Which type of portable lighting may be used to enter a compartment on a tank barge which is NOT gas-free? An explosion-proof, self-contained, battery-fed lamp A three-cell flashlight A spark resistant and flame retardant lamp None of the above Tank Vessel Safety
A What best describes for how long a gas-free test is good? For the instant that it is made For as long as is indicated on the gas-free certificate Until valves in line with the tank or compartment are reopened Until changes in temperature or pressure affect the vapor content in the space Tank Vessel Safety
