Mercury Spills

The following procedures must be followed in the event of a mercury spill:

  1. Call REM at (765) 494-0121 during normal business hours (Monday-Friday, 7:00 am - 4:30 pm) to report the spill. REM will provide assistance.
  2. Call Purdue Police at (765) 494-8221 after business hours to report the spill. Purdue Police will contact REM to provide assistance.
  3. If possible, contain the spill. An attempt should be made to prevent mercury from entering drains, cracks or other crevices.
  4. Keep people away from the spill area. Before leaving the area, check for mercury on clothing and the bottom of shoes. If mercury is visible on any articles of clothing or shoes, remove and keep those articles in the area.

Never pour mercury down the drain or dispose of in the trash. All mercury, including contaminated debris, must be collected for disposal.

Mercury can be found in a variety of non-laboratory items such as fluorescent light bulbs, thermometers, older pressure gauges, plumbing traps and vacuum pumps. When mercury is spilled, it forms beads or droplets that can accumulate in the tiniest places. These droplets can emit vapors into the air that are unseen and odorless. Breathing mercury vapors can be very dangerous, depending on the amount inhaled and the length of exposure to the contaminated air.

Amount of elemental mercury in various items:

  • Fluorescent light bulbs have 10 to 40mg of mercury
  • Thermometers have 50mg to 3g of mercury
  • Older Pressure Gauges have 3 to10g of mercury
  • Plumbing Traps can have 100g to several pounds of mercury


  • Never pour mercury down the drain 
  • Never burn mercury 
  • Never put mercury in the trash 
  • Never allow people whose shoes or clothing may be contaminated with mercury to walk around the room or into a hallway. 
  • Never use an ordinary vacuum or a shop vacuum to clean up mercury


  • Call REM at 40121 or Purdue Police at 48221(911) to report a mercury spill. 
  • Keep everyone away from the area of spill. Before leaving the area check for mercury on clothing and bottom of shoes. If mercury is visible on any articles of clothing or shoes, remove and keep those articles in the area. 
  • Keep the incident area under 70 degrees F to minimize the release of mercury vapors. 
  • Keep air flowing in the area. Close the inside doors of the area.  If weather allows, open any exterior windows. Use fans in the area that pull inside air outside. 
  • If you or any other people have come in contact with the mercury, stay in the area so you do not spread the contamination. 
  • Contain the spill. Make sure the mercury does not move to drains, cracks, or crevices. If you leave the incident area, make sure your clothes and shoes are not contaminated with mercury.
