Question:
What conditions could cause a railroad employee to believe a hazardous material car is leaking:
frost forming on external fittings
small puddle under the car
strange smell near the car
all of the above
Answer
small puddle under the car
This is one of the conditions that could cause a railroad employee to believe a hazardous material car is leaking because these are entirely caused by leaking oil or so from the car
Explanation
If there is more than a very small puddle at the back of the car, then there is a coolant leakage. Sometimes cars leak, leaving ominous spots or puddles on the ground or behind and this can be used to identify any leakage from the car. hence, this is one of the conditions that could cause a railroad employee to believe a hazardous material car is leaking because these are entirely caused by leaking oil or so from the car
