V. C. Evacuation Plan: If There is a Medical Emergency

1) If a Co-Worker is Exposed to a Hazardous Chemical:

2) If a Chemical is Spilled, With No Personnel Injured:

a. General information regarding chemical spills

for the University's HazMat Team for assistance

b. Reacting to the primary hazard of the chemical spill

Your reaction to a chemical spill should depend on the nature of the spilled material. The following instructions are arranged according to the specific chemical class hazard. Spills involving multiple chemicals must be approached with extreme caution due to the possibility of reactions between incompatible agents.

i. Primary Hazard: Material is Flammable Liquid

ii. Primary Hazard: Material is an Extremely Toxic Liquid

iii. Primary Hazard: The Material is a Corrosive Liquid

iv. Spills Involving Solid Chemicals

v. Spills Involving Mercury

(Hako Minuteman MRS-1)


1. The mercury recovery vacuum should be

a) fully assembled when you pick up from the research stockroom, 014


b) have intakes sealed and no attachments attached. If so, attach the plastic collection jar to the mercury separator. Remove the plug from the tank intake and insert the separator.

2 Plug in electric cord and turn on vacuum on. Spray aerosol anti-static spray into floor tool for 2 - 3 seconds. This will coat the inside of the wand assembly, hose and separator, reducing static electricity during the liquid mercury pickup.

3. Vacuum up the spilled mercury or mercury oxide waste. Do not use the vacuum for general cleaning, only for mercury spills.


You will be responsible for cleaning the vacuum after each use and for reassembling it according to the following instructions.

4. After the spill is cleaned up, remove the wand assembly or other pickup tools from the hose and place the tools in the plastic bag provided.

5. Remove the hose from the separator, insert the plugs provided at each end of the hose and place in the plastic bag with the tools.

6. Remove the collection jar from the separator and cap the jar until the contents can be transferred into a container for waste disposal. Once the waste is transferred into a waste container it must be properly tagged for waste disposal.

7. Leave the separator on the tank assembly; plug the openings of the separator with caps provided.

8. Unplug electric cord from wall. Remove vacuum lid assembly.

9. Take elastic band of top filter bag (white Dacron) and snap it over the gasket rim of the filter unit. Remove the filter unit, with white filter bag attached.

10. Remove the bottom, disposable filter protector bag (brown paper), by reaching down to the center of the bag and pulling it inside out towards you. Gently remove the elastic band from around the vacuum assembly, do this without snapping the elastic. Place this filter protector in the disposable plastic bag provided.

11. Remove the collector bag itself from the bottom of the vacuum by gently pushing the collar of the filter bag down and off the intake tube. Place one of the "mercury caution" decals over the bag opening and remove the filter bag from the vacuum tank. Place the collector bag in the disposable plastic bag with the filter protector.

12. Wipe down the inside of the vacuum with damp disposable towels. Tag and dispose of these, along with the other contaminated items, for waste collection.


13. Open the folds of a new collector bag and insert into the vacuum tank. Place the cardboard collar over the intake tube and pull the collar over the tube until the rubber gasket is past the ring on the end of the tube.

14. Place a new brown paper filter protector into the tank and snap the elastic band around the rim of the tank.

15. Place a new white Dacron filter into the tank and snap elastic around the rim.

16. Place bag frame with ring side down into the Dacron filter.

17. Replace the filter unit with gasket seating around tank rim.

18. Replace vacuum lid assembly, securing the two side clasps.
