Dealing with Unmarked Chemicals

When working with industrial sites, especially older ones that may have been abandoned, we occasionally come across some chemicals in unmarked containers. These containers need to be removed like everything on the site, but the ambiguity makes it hard to know what to do. If the chemicals are toxic, they need to be identified and dealt with very carefully. Here’s how we go about identifying and disposing of unmarked chemicals.


The first step is to figure out what’s in the container. If we are unable to determine the contents of a container, it will need to be stored separately in a contamination area. Those that can be identified will be disposed of using whatever methods and procedures are stipulated for that particular chemical. Those that cannot be initially identified may need to be tested to confirm the nature of the chemical.

Container Integrity

Once we know what’s in the container, we need to move them to the appropriate places. Before we do that, it’s important to check the integrity of the container. The last thing we want is to spring a leak during transport. If the container isn’t sound, we can use a secondary containment system to prevent contaminating the surrounding environment.


Every chemical will have its own specifications that need to be followed for safe disposal. Once everything has been identified and we know what we’re dealing with, we can create a plan to follow all safety procedures and dispose of the chemical containers.
