If you have witnessed a hazardous waste spill at your business or residence, and are wondering how to respond to such a situation, this article is for you!

The following procedure will explain the steps necessary to control the spill of a substance that risks harming the environment and the health and safety of workers and the community. A proper hazardous spill response plan will limit the impact of such an incident.

1 – Evaluate the situation

The first thing to do in the event of an accidental hazardous spill is to assess the situation.

You should first use caution to identify the substances spilled and locate them visually, if possible, to determine the source of the leak.  If the spilled substance releases dangerous gases or is prone to explosions, move away from the accident site and establish a safety perimeter. Quickly contact an emergency spill response company when you are in a safe area.

For more information on a chemical substance, you can read its Material Safety Data Sheet (MSDS). However, regardless of the nature of the hazardous material, you should always seek the assistance of hazardous waste management specialists in order to minimize the risk to your health.

2 – Stop or control the hazardous material spill

If the dangerous goods in question can be harmful to your health, attempt to control the spill while waiting for the emergency environmental response unit.

Before approaching the spill, make sure to turn off any appliances or devices that could create a spark or be a source of ignition (cigarette, engine, telephone, etc.). Slowly approach the hazardous spill with the wind at your back—to avoid breathing in harmful gases—while wearing protective clothing and gloves.

You can then control the leak as best as you can with one of the following strategies:

  • Direct the leak into an empty container
  • Place absorbent pads
  • Move the leaking container
  • Perform temporary repairs
  • Use any other method that could be efficient without posing additional risks

3 – Contain the hazardous waste spill

You should then contain the spilled material in the smallest possible area.

If the spill is outside, on the ground or on the road, it will be important to protect nearby sewers and waterways by trapping contaminants with soil or sand embankments. You can also use absorbent materials to prevent the hazardous substance from entering the ground.

If the spill is in water, you can slow down the spread of the substance by using floating barriers, booms or a rudimentary dam.

Finally, if the spill is in an industrial building, you should cover drains and use absorbent materials to avoid dispersion on the sealed surface.

4 – Recover spilled material

Recovering hazardous spilled material and restricting its migration as much as possible involves taking into account the material properties and the weather conditions.

An emergency environmental services company may need to pump hazardous products using specialized equipment or even excavate the soil to remove contaminants. In less severe situations, you may absorb the hazardous waste spill with pads, pellets, sawdust, sand, etc.

Warning: all materials that were in contact with the spilled material must be stored properly until disposal.

5 – Dispose of contaminated materials

Disposal of hazardous materials must comply with government regulations. For example, contaminated soil or the contents of a vacuum truck used for pumping have to be transported to an authorized treatment or landfill site.

If you work with an environmental services company, it should have a hazardous materials transportation permit which allows it to legally circulate with hazardous residual materials.

6 – Prepare a spill report

The last step to follow in a hazardous waste spill response plan is to prepare a report containing relevant information about the event :

  • Date and location of the spill
  • Description of the incident and related damages
  • Causes of the incident
  • Temporary and permanent corrective action following the event
  • Description of third party damages (if any)
