What is one of the risks associated with oily rags?

• A. They can spark
• B. They can spontaneously combust
• C. They reduce air quality
• D. They cause slipping hazards

Answer: (B)

Oily rags pose a significant risk of spontaneous combustion due to their chemical composition and the nature of the oils they absorb. When rags are saturated with oils, particularly those that contain volatile organic compounds, the heat generated from the oxidation process can accumulate. If these rags are collected and stored without proper ventilation, the temperature may rise to the point where they combust without an external ignition source. This spontaneous combustion occurs because the oil undergoes an exothermic reaction, and with the limited air exposure, the heat cannot dissipate effectively, leading to ignition. Therefore, it's crucial to handle and store oily rags appropriately, typically in a metal container designed for such materials, to mitigate the fire hazard they present. While other options touch on important safety considerations—like slipping hazards from wet rags, potential air quality issues from chemicals, and the possibility of sparking from friction or static discharge—they do not directly address the critical issue of spontaneous combustion, which is uniquely prevalent in the case of oily rags.
