Waste containers provided by EHRS should only be used for the collection of chemical wastes. Please do not use EHRS provided bottles for other applications outside of waste collection.
EHRS waste containers are made from HDPE (High Density Polyethylene) and have been tested against all manner of waste streams. While there are some compatibility charts that identify HDPE as being incompatible or otherwise not recommended for specific chemicals, those assessments are made in the context of how the chemical effects the container and how the container effects the chemical. There have been no compromised bottles because of how chemical incompatibility since at least 2013.
