Case Study Unit III Environmental Health and Science

 
The Scenario:
You are an Environmental Health and Science professional returning home from your plant on a summer friday afternoon at about 4 p.m. You have just picked up some materials from a nearby building supply store for a weekend backyard project (cement, sand, wood, concrete blocks, lumber, ext.). You are about one mile outside of the main population zone of your small town, and you come upon an accident scene in which a placarded tanker truck is turned on its side in a ditch about 25 feet off the two-lane road. there is no sign of fire and no sign of the driver from your vantage point inside your truck. the only sign you can see from your vantage point is a "Dangerous When Wet" placard with a Class 8 label code and a UN 1836 on an orange panel. What might this chemical be? You can make out an NFPA diamond with a 0 at 12 o’clock; a 2 at 3 o’clock; a 4 at 9 o’clock; and a slashed W at 6 o’clock. You take out your small binoculars and scan the scene. There seems to be a thin, small volume of dripping liquid (red to yellow color) coming from the valve on the tanker.

There is an agricultural field directly next tot he incident site. A large irrigation unit is sparing the fields, but the extent of the spray seems to end 20-25 yards away from the overturned truck. Slight but steady winds are blowing at 5-8 mph across the scene towards the town.

Your town has a fire department but it does not have a hazardous material squad attached to it. Your Chemical plant (3 shift operation, bleach, pool chemicals, and household products, 15 miles away) does have a hazardous material team that you trained and is under your direction. You do have your cell phone and and emergency response guidebook.

Questions:
1) How should you proceed? Discuss the actions you should take.
2) What, if any, retrains should you exercise?
3)What advice would you give any other individuals or drivers coming upon the scene?
4) What would you say to the next responders coming to the scene?
