Levels of Protection Exercise

For each of the scenarios, identify the level of protection needed.  Also, recommend other actions you believe are necessary.

Hazardous Waste Operations

Scenario 1:  A 1/4 acre hazardous waste site contains 25 open and closed drums.  A flame ionization detector measures 50 "meter units" in the atmosphere near the drums.  Workers must enter the site to take soil samples.

Scenario 2:  An unprotected response team enters a vacant warehouse and measures the atmosphere for combustibility.  The combustible gas meter indicates 0% after deflecting to 100% and falling rapidly back to the 0% mark.  Workers must identify the source of contamination.

Scenario 3:  An initial site survey team investigates an abandoned hazardous waste site containing spilled liquid and drums.  The team has measured 5 ppm of organic vapors with a photoionization detector and a radiation level of 70 uR/hour.  Response workers are returning to further characterize the site.

Scenario 4:  A team must enter a small room where 500 ppm of acetone has been detected (using detector tubes).  The concentration appears to be steady and no other contaminants are apparent.  Workers must identify the source of contamination.

Scenario 5:  Several drums marked "pesticides" must be moved from a site previously used to store extra supplies for a chemical firm.  Several of the containers are open and some have apparently been punctured.

Scenario 6:  An initial reconnaissance team starts to enter an abandoned waste site containing numerous open drums and a large pool of liquid.  There is no live vegetation around the site and two dead animals are lying near the entrance.  No other information is available.

Emergency Response

Scenario 7:  A 50,0000 gallon storage tank containing JP-4 has leaked must of its contents.  A large area of liquid is puddled on the ground.  Workers must begin cleaning up the site.

Scenario 8:  A truck carrying styrene is involved in an accident.  There are no apparent leaks, but the concentration of vapor near the truck is 700 "meter units" measured with a PID.  You must enter the area to further evaluate the situation.

Scenario 9:  An ammonia vapor cloud forms after a tank truck has an accident.  Response personnel must enter the cloud to repair the leak.  The concentration of the ammonia at the edge of the cloud is 300 ppm.

Scenario 10:  A truck has a wreck and sends a load of drums into a deep ditch.  Response personnel measure 18% oxygen and a combustible gas meter reading of 40%.  Personnel must go into the ditch to determine if the drums are damaged or leaking.

Note:  Level B is the minimum for entry into an unknown / uncharacterized site.
