Scenario:
Imagine you are the manager of a small car repair shop. You are responsible for ensuring proper waste oil disposal.
Task:
**Potential Sources of Waste Oil:** 1. Oil changes 2. Engine flushes 3. Transmission fluid changes **Safe and Responsible Collection & Storage Methods:** 1. **Labeled Containers:** Use clearly labelled containers specifically designated for waste oil. Ensure containers are leak-proof and made of materials compatible with oil. 2. **Spill-Proof Drums:** Invest in spill-proof drums with secure lids. These drums should be large enough to accommodate the volume of waste oil your shop generates. **Local Waste Oil Acceptors:** 1. [Insert a local recycling center or waste management company] 2. [Insert a local re-refining company or organization]
