Paint Related Materials (Adhesives, Caulks, Resins)

Definition

There are many different types of paints, stains, adhesives, caulks, and resins utilized in MSU operations, and with a few exceptions, most of these maintenance type materials can be divided into two categories: Flammable and Non-Flammable. Both categories, whether solid or liquid, must be disposed of through the EHS Hazardous Waste Program. In general, these materials cannot be disposed of in the general refuse or the drain with the exception of hardened latex paint as noted below. Refer to MSU’s Drain Disposal policy.

Paint-related material waste can be minimized by purchasing only enough materials for the job at hand.

Common Types of Paint Related Materials Waste at MSU:

  • Flammable: Oil-based paints, solvent based epoxy paints, stains, thinners, and some resins
  • Non-Flammable: Latex paint, building caulks, adhesives, and some resins

In addition to the liquid waste, any rags or wipes that were utilized for the cleanup of flammable paints, stains, thinners, etc. are a flammable solid and must be disposed of through the EHS Hazardous Waste Program.

Latex paint that is hardened and contains no flowable liquid or sludge can be disposed of in the general refuse garbage. Remove the lid prior to throwing away so the refuse hauler can see that the containers are empty or solidified.

Container Type

If disposing of unwanted paint related materials in the original manufacturer’s bottles with an intact label, the materials can be given directly to the EHS Hazardous Waste Program for disposal and should not be transferred into another container.

When reusing empty containers, they must be compatible with the type of chemical waste stored in them. Empty reagent bottles can be used for chemical waste collection after following the Empty Bottle guidance in the Waste Section of the EHS website.

Although EHS does not maintain a list of compatible materials, in general paint related materials can be stored in glass and plastic containers. However, do not store liquid waste in containers that previously held solids, as they will leak. Container compatibility information is also available on Safety Data Sheets. EHS provides 5-gallon high density polyethylene (HDPE) carboys for liquid hazardous waste storage, which are proven to be compatible with a variety of waste types.

Storage

Waste containers must be kept free of any liquids or residue on their exteriors. EHS Hazardous Waste Staff will reject any container with liquid or residue on the exterior until it has been cleaned. Leaking waste containers will not be accepted, and the contents must be transferred to a new container prior to disposal by the EHS Hazardous Waste group.

  • All container lids MUST be closed tightly unless waste is being actively added to the container.
  • Do not overfill containers.
  • Secondary containment is not required but is recommended for waste storage.
  • Do not accumulate more than 55-gallons total of hazardous waste in your location. This limit applies to the sum of full containers and partial containers being filled.
  • Submit frequent requests for waste pick up through the EHS Hazardous Waste Request form to stay within the 90-Day storage limit and minimize the amount of waste containers in your space.
  • Do not move hazardous waste from the location that it was generated.

MSU Waste Tag Required

Yes - A MSU Waste Tag is required for all waste not contained in a manufacturer’s bottle with an intact or legible label.

No - A MSU Waste Tag is not needed when submitting chemical reagents in the original manufacturer’s bottle with an intact label.

MSU Waste Tags must be directly affixed to the waste container either with string, a twist tie, chain and clipboard, rubber band, or tape. MSU Waste Tags are provided by EHS and can be requested through an EHS Hazardous Waste Request.

Labeling

A MSU Waste Tag should be filled out and completed when the first drop of waste is added to the container, or when the material becomes unwanted. The date the first drop or piece of waste is added to the container starts the 90-Day accumulation limit.

The contact information at the top of the MSU Waste Tag must be filled out to identify where the hazardous waste was generated, the container size and type, and who to contact with questions regarding the waste container.

All chemical constituents must be accounted for on the MSU Waste Tag. Chemical names must be printed legibly, in English, and with no abbreviations. The amount of chemical constituents can be captured by either using percentages up to 100%, or by units of volume. Either way, these need to match the amount of waste in the container when EHS arrives to pick up the material. Inaccuracies and discrepancies on the MSU Waste Tag can result in the waste being rejected by the EHS Hazardous Waste Staff for safety and compliance reasons. For aqueous solutions, the check box for “Water Balance” can be used to account for the remaining percentages or volume. Chemical constituents must be identified on the MSU Waste Tag as they are added to the container, as guessing the contents of a full container creates safety and compliance violations.

Review and check all applicable potential hazards at the bottom of the MSU Waste Tag each time when adding waste to the container. The color and consistency section can be completed when the container is full, or when approaching the 90-Day storage limit.

Guidance on how to accurately fill out the MSU Waste Tag can be found in the Waste Section of the EHS website.

Submit Hazardous Waste Request

When the container is full or close to the 90-day accumulation limit, submit a Hazardous Waste Request via the EHS Safety Portal as follows:

  • EHS Website: ehs.msu.edu
  • Log in to the Safety Portal through a preferred web browser using your MSU Net ID and EBS Password
  • Select Hazardous Waste Request
  • Paint Related Materials are found under the Common Process category
    • Paint – Flammable (Use for flammable paint related materials)
    • Paint – Latex (Use for non-flammable paint related materials)
    • Adhesives
