Managing Mercury Switches Found in Vehicles Fact Sheet

Fact Sheet, January 2007

Introduction

For: Scrap metal recyclers, auto dismantlers and auto repair shops.

This fact sheet explains how to remove, replace, and handle mercury switches in vehicles. It also tells you about changes in the laws that say how to dispose of mercury and what to do if you have a spill. This fact sheet does not replace or supersede statutes or regulations. Always review the most current statutes and regulations. Mention of vehicle makes and models, repair facilities, or mercury switch handling facilities or other companies in this fact sheet is not to be construed as an endorsement by DTSC.

What is Mercury?

Mercury is a metal with special properties. It is liquid at room temperature and conducts electricity. This makes it ideal for use in light switches in vehicles.

What is a Mercury Light Switch?

Mercury light switches look like small capsules. When you open the hood or trunk of your car, the mercury moves to the end of the capsule and touches an electrical contact and the light turns on. When you close the hood or trunk, the mercury moves away from the contact and the light turns off.

There are also mercury switches in other parts of vehicles, such as the ABS system G-force sensors.

How Much Mercury is in a Light Switch?

A mercury light switch contains about one drop of mercury.

Is Mercury Dangerous?

Mercury is poisonous. If mercury is not disposed of safely, it can be released into the environment and harm people and wildlife.

Contact with mercury can cause:

  • birth defects,
  • nerve disorders,
  • brain damage, or
  • death.

How Do People Come into Contact with Mercury?

Mercury can be inhaled, absorbed through the skin, or eaten (in contaminated food).

Are There Laws About Handling Mercury?

Yes. In 2001, California passed a law called SB 633. This law:

  • makes it illegal to sell certain items that contain mercury,
  • encourages people who dismantle, recycle and repair vehicles to remove mercury switches, and
  • makes the rules for handling switches simpler.

More information about Mercury and SB 633 is available at the DTSC website.

In 2003, DTSC adopted the “Mercury Waste Classification and Management regulations.” The regulations cleared up the rules for people who handle mercury switches removed from vehicles, and changed the rules for people who dismantle and recycle vehicles.

Starting January 1, 2005, a vehicle with a mercury switch is considered hazardous waste as soon as someone decides to

  • crush,
  • bale,
  • shred, or
  • shear it.

Since January 1, 2005, if you crush or shred a car without taking out the mercury switches, you will be breaking the law.

These laws also say you can handle mercury switches like universal waste.

Note: You do not have to remove the switches if damage to the vehicle makes it impossible.

What is Universal Waste?

Universal waste is a type of hazardous waste that uses simpler rules for transportation and disposal than the ones for other hazardous wastes.

How Do You Know if a Car Has Mercury Switches?

Below are lists car makes and models that have mercury switches in the hood or trunk. Additionally, the End of Life Vehicle Solutions (ELVS) vehicle list also has a list of vehicles. Neither list is all-inclusive. To be sure, check with the vehicle manufacturer.

Note: If a car has a hood or trunk light, and you don’t see a mechanical switch, it probably has a mercury switch.

Who Should Remove Mercury Switches from Vehicles?

Anyone who plans to crush, bale, shear, or shred a vehicle has to remove the mercury light switches from the hood and trunk. Usually, car dismantlers and scrap metal recyclers do this.

Auto repair shops do not have to remove mercury switches when they work on cars that are still in use. But, DTSC encourages repair shops to offer to replace and recycle mercury switches in the cars they repair. If a repair shop replaces or removes a mercury switch, they may handle it like universal waste.

Note: Before you remove mercury switches, make sure you and your employees know how to handle them safely, and know what to do if there’s a mercury spill.

When Should Mercury Switches be Removed?

It is easiest for dismantlers to remove mercury switches when they remove the battery, coolant, and brake fluid.

How Do I Remove Mercury Switches?

DTSC has created training manuals that tell you how to safely remove mercury switches from vehicles.  They can be found on our Mercury Publications page.

How Do I Store Mercury Switches?

  • Keep the mercury switches in a closed container in good condition.
  • Do not use a metal container. Mercury can react with metal or leak through the seams.
  • Wrap the switches in padding, like bubble wrap, so they won’t break.
  • Keep the containers where they won’t be disturbed.
  • Mark the container. Write on the label:
    • “Universal Waste – Mercury” or
    • “Waste – Mercury Switches” or
    • “Used Mercury Switches”

How Long Can I Keep Mercury Switches?

If you handle them as universal waste, you can keep mercury switches for up to a year. Write the date on the container when you first store a mercury switch in it. That way you can show an inspector that you have not kept mercury switches for more than a year.

Do I Need an EPA Identification Number to Handle Mercury Switches as Universal Waste?

You do not need an EPA ID number unless you have more than 11,000 pounds of universal waste at one time. But, you still have to:

  • Have a system for cleaning up mercury, and
  • Train employees on how to handle switches and what to do in an emergency.

Do I Need a Special Carrier to Transport Mercury Switches?

No. If you handle them as universal waste you can transport the switches yourself. They have to be in sealed containers. If a switch is broken or damaged, put it in a sealed plastic bag inside the container. You do not have to use a hazardous waste manifest or a registered hazardous waste transporter.

If you handle other hazardous wastes, you can use your hazardous waste hauler to transport your mercury switches. You can also hire a commercial carrier that takes universal waste. Make sure the carrier knows and follows the rules for transporting universal waste.

If you ship packages of mercury switches by air or by water, you must follow the regulations for transporting hazardous materials found on the U.S. Department of Transportation website. If you use ground shipment, your package must meet the DOT regulations only if it contains more than one pound of mercury.

There is a new program that is available in California for the collection and proper disposal of mercury switches obtained from vehicles. This program provides collection buckets and educational materials regarding the switches and the program. It also provides a method for free disposal of the switches, and may even pay you to collect these switches. For more information, please contact the ELVS program, or DTSC.

Where Can I Ship Mercury Switches?

If you do not use the mercury switch collection program listed in the previous paragraph, you have to ship mercury switches to an authorized mercury recycling facility. You can take your mercury switches to a recycler or to a universal waste handler who collects switches before sending them to a recycler.

Below is a list of mercury switch handlers, transporting facilities and waste destination facilities in California.

Do I Have to Keep Records?

Yes. If you manage mercury switches as universal waste, then you must keep the following records for at least three years:

  • How many vehicles you crushed, baled, shredded, or sheared,
  • How many of the vehicles had mercury switches,
  • How many mercury switches you removed from the vehicles, and
  • How many vehicles had mercury switches that you could not remove because of accident damage.

Can I Replace Mercury Switches?

Yes. You can replace them with switches without mercury. They will work in almost all vehicles.

Here is a company that manufacture and supply mercury-free switches:

Comus International
454 Allwood Road
Clifton, NJ 07012
Tel: 973-777-6900
Fax: 973-777-8405

Note: DTSC does not endorse this company. Contact the company if you have questions about replacing mercury switches with mercury-free switches.

What if There is a Mercury Spill?

Be very careful! It is dangerous to inhale, swallow, or handle mercury. If you see a broken, leaking, or damaged mercury switch, put it in a sealed plastic bag and then into a container.

Do not try to vacuum a mercury spill! Vacuuming spreads mercury vapors into the air. It can do more harm than good.

Write a plan of what to do if there’s a mercury spill. Keep personal protective equipment and a mercury spill kit nearby when you remove mercury switches. Make sure that the staff knows exactly how to use them. You can get affordable spill kits from laboratory and safety supply stores.

What if Someone Is Exposed to Mercury?

Mercury on the Skin

Wash the skin with soap and water. Remove all clothes that touched the mercury. Seal the clothes in a plastic bag. Put the plastic bag in a hazardous waste container. See a doctor right away!

Mercury in the Eye

Flush eyes with water for 15 minutes. See a doctor right away!

Swallowed Mercury

Get medical help right away! Call your poison control at (800) 222-1222 or your doctor for more information.
