Using nail polish remover requires careful attention to safety due to its flammable nature. Keeping it away from heat sources and open flames is essential because most nail polish removers contain acetone or other solvents that can easily ignite. These substances evaporate rapidly, creating vapors that can catch fire if they come into contact with flames or high heat, posing a significant fire hazard.

The other choices do not provide safe practices: using it in a warm room might encourage quicker evaporation and potentially raise fire risk, applying it directly to the skin for stain removal could cause skin irritation or chemical burns, and limiting its use to only acrylic nails does not account for other safe and appropriate uses, such as on natural nails. Therefore, the emphasis on fire safety is the crucial aspect that underscores the importance of this precaution.
