What must be done when it’s determined operations involve asbestos contamination
10-80 specifying asbestos, minimize contact, use SCBA, & wet asbestos w/fog nozzle or spray stream to prevent fibers from becoming airborne, limit overhauling, & prevent cross contamination
T/F The 1st Lad performed thorough & complete overhauling of suspected asbestos covering in order to limit exposure to other units. Is this a good action?

Incorrect
A. Propane can BLEVE. A satisfactory performance of a relief valve cannot prevent a BLEVE
B. Impact failure of a cylinder in a transportation accident can also cause a BLEVE

A. 1 beep (every 5 seconds)
B. 1 flash (every 5 seconds)
C. 1 quick vibration (every 5 seconds)
D. A low battery icon will appear on the display
C 1 quick vibration (every 1 minute)
CO Meter Low battery alarm 1 beep and flash every
5 seconds with 1 vibration every 1 minute
OSHA states max safe working level of CO _ ppm over 8 hours at work place vs _ ppm over 8 hours at residential levels
Work: 35 ppm
Residential: Not to exceed 9 PPM
SCBA for CO Incident vs Emergency
Incident 9: PPM/less with No occupant symptomatic (Wear SCBA);
Emergencies: Occupants symptomatic or >9 PPM (Use SCBA)
ID number on placards for Compressed Natural Gas
Can CNG cylinder BLEVE
1971
Subject to failure, but NOT BLEVE because they do NOT contain liquid
Choose the correct
A. IC didn’t call Haz Mat 1 to a RR car derailment due to no damage being suffered to the car
B. Muriatic acid used to clean the facade of the wall- Off ordered spraying stopped & ensured response of Haz Mat although there was no spill
C. Water was used on a fuming product prior to hazard assessment being completed to reduce exp problem
D. Off relayed name of material to Dispatch letter by letter for notification to Chemtrec & Haz Mat Response Team (HMRT)
Answer D
A= Haz Mat response for all RR car derailments even if no damage suffered to car
B. Haz Mat response for spill of Muriatic Acid
