How often should oily rag containers be emptied?

• A. Weekly
• B. Monthly
• C. Daily
• D. Annually

Answer: (C)

Oily rags can ignite spontaneously as oils oxidize and generate heat. To keep that heat from building up and to reduce vapors that could feed a fire, these containers must be emptied regularly. Doing it daily removes spent, heat-creating rags before a dangerous concentration can develop, which is why daily is the standard practice in maintenance shops. Waiting longer—weekly, monthly, or annually—lets rags accumulate and increases fire risk, and would not meet safety expectations for oily waste disposal.
