Which of the following is a necessary characteristic for a location to be suitable for chemical storage in a laboratory?

• A. Proximity to open flames and heat sources
• B. Direct sunlight and high humidity
• C. Unrestricted public access
• D. Good ventilation and temperature control

Answer: (D)

Verified step by step guidance

1. Understand the importance of chemical storage safety in a laboratory setting, which aims to prevent accidents, chemical degradation, and exposure risks.
2. Recognize that proximity to open flames and heat sources is unsafe because many chemicals are flammable or reactive to heat, increasing the risk of fire or explosion.
3. Identify that direct sunlight and high humidity can cause chemical degradation or unwanted reactions, making these conditions unsuitable for storage.
4. Note that unrestricted public access is unsafe because it increases the risk of accidental exposure or misuse of chemicals.
5. Conclude that good ventilation and temperature control are necessary characteristics because they help maintain chemical stability, reduce the buildup of hazardous fumes, and ensure a safe environment.
