Lab Day A B C D Date ____________________ Lab Teacher ___________________ “The Hazmat Alert” Finding the density of liquids Time - 14:00:00 Zulu Location – Gulf of Mexico Coordinates: 25o 15’ N, 95o 10’ W Local Buoy Report: 25 – 50ft seas, calming winds Intelligence Report Three cargo and tanker ships from a convoy of six vessels have been reported missing. Radio communication is blacked out and the identity of the missing vessels is unknown. Rescue, recovery, and Hazmat teams have been alerted. Mission Your Hazmat dispatch group is responsible for deploying the appropriately equipped Hazmat teams to the contaminated area.

All measurements should be made to the nearest tenth. Sample Gross (g) Tare (g) Net (g) Volume (ml) Density Cargo A B C Mission Phase II: You have determined the identity of the three spilled fluid cargos A, B, and C. Now use this knowledge and the Coast Guard Report to infer the names of the missing vessels. Cargo A ________________________ Vessel Name ____________________________ Cargo B ________________________ Vessel Name ____________________________ Cargo C ________________________ Vessel Name ____________________________ Mission Phase III: Examine the various Hazmat response team capabilities and equipment below. Dispatch the best-equipped team to contain and clean each spill. The density of each spilled cargo should be considered when you select the teams. *Note: Not all teams need to be utilized. Specialty: Beach containment and clean up Dispatch to spill area (A,B,C) No use Equipment: Jet Skis, quads, 9x40 airtight mobile canisters, 6 cu/yd front-end loaders Specialty: Floating, flammable, low viscosity (not thick) liquids containment and recovery Gasoline (alcohol) SludgeBusters ScumSuckers BottomFeeders Equipment: Fire retardant suits, surface skimmer vacuums, Floating containment booms Specialty: Crude Oil ,Gear Oil, and Motor Oil Spills Equipment: Oil resistant suits, surface skimmer vacs, Floating containment booms, and oil-absorbent mats Specialty: Deep sea bottom recovery. Equipment: M28 high-pressure suction vacuum, scuba tow, mini-submarine; Alvin Crude Oil (90 w) TNT (Molasses & LEAD beads) 2 Mud Dawgs Team Specialty Page Team Name Assessment of Lab Skills and Knowledge 1. Explain the purpose of finding the tare value. Use the word “container” in your answer. _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ 2. The BD Matilda and the SS Rossi are identical ships in crew, cargo capacity, and empty weight. Diagram A (below) shows the BD Matilda fully loaded with Dioxan floating on a calm sea. The water surface is indicated by a horizontal line. Diagram B (below) shows the SS Rossi fully loaded with Olive Oil floating nearby. Using your knowledge of density, predict and draw the level of the water surface on the SS Rossi. B.D. Mathilda S.S. Rossi Circle one Page contents of the B.D. Mathilda. 3 3. I drew the water level HIGHER / LOWER along the hull of the S.S. ROSSI Circle one because the ____________________ it is carrying is MORE / LESS dense than the Circle your choice for the best answer to the following questions. 4. Page 4 5. 6. Determine the density of the Fluid in container D. Show your calculation using the three step method. Density Calculation Mass= ___________ Volume= _________ 1. Density= Mass___ Volume 2. D= 3. D= Bonus Page 5 Pretend the Coast Guard had brought single sample container filled with cargo from each ship. In the container on the right, draw the various fluids arranged in order of density. Give each fluid a pattern and provide a key. Label each layer with its density.
