containers if the containers:
- hold hazardous substances
- hold decanted hazardous substances that are not consumed immediately
(though the label need only have the product name and risk and
safety information)
- hold items (and substances) which can produce hazardous substances
- are not cleaned (until they no longer contain a hazardous substance).
