• Extract any liquid that may be inside the blister and send it to the lab for further

analysis

Correct Answer:

• water freezes.
• humidity decreases
• condensation occurs.
• the air is saturated.

Correct Answer:

• condensation occurs.

• If a contractor is using a poorly maintained compressor to supply air for abrasive blast

cleaning and conventional air-spray, the coating inspector should perform a

• dry film thickness (DEI) measurement.
• wet film thickness (WFT) measurement.
• blotter test for the presence of oil and water. 1 / 3

• vial lest.

Correct Answer:

• blotter test for the presence of oil and water.

• Upon arrival of coating materials, the inspector should

• review coating contractors' plans for storage of coating materials and confirm they

meet national, local and owners' fire and environmental regulations.

• observe and document the amount of material and batch numbers. C. observe aryl

document that the applicator WFT at regular intervals during application.

• observe and document time frame and environmental conditions between each coat.

Correct Answer:

• observe and document the amount of material and batch numbers.

• Relative humidity is

• a measure of the amount of moisture in the air compared to saturation level.
• a measure of the amount of moisture in the air compared to the air temperature.
• the lowest temperature at which moisture forms on a steel surface. D. the highest

temperature at which moisture forms on a steel surface.

Correct Answer:

• a measure of the amount of moisture in the air compared to saturation level.
