Bring materials in their original containers. If this isn’t possible, label the container if you know what the material or chemical is.
Use containers that have secure screw tops (five-gallon pails are okay). Do not use containers with press tops such as cottage cheese containers.
Do not bring items in glass bottles or jars, unless it is the original container.
Keep automotive fluids like motor oil and anti-freeze separate. Do not put them in the same container. If you are filling a container that is one gallon or larger, leave at least two inches of air space at the top.
Oil - Motor and all cooking oils - canola, olive, peanut, vegetable, etc. Please bring in containers no larger than 6 gallons. Multiple containers are acceptable.
Place all cans and bottles in a rigid box (cardboard or plastic tote). If a container is leaking, place it in a plastic bag and then put the bag in a box.
