Which materials do dry survey areas typically use?

Dry survey areas primarily use M8 paper, which is specifically designed for detecting chemical agents in the field. M8 paper changes color in the presence of specific nerve and blister agents, making it an effective tool for hazard identification in a dry environment. Its use in dry survey areas is crucial for ensuring safety and effective response measures during emergencies.

In contrast, tar paper is often used for roofing and insulation rather than for survey purposes. Plastic sheeting serves as a barrier or cover in various applications but does not provide the chemical detection capabilities of M8 paper. Foam sheets are typically used for insulation and cushioning, lacking the necessary properties for surveys in hazardous environments. These distinctions clarify why M8 paper is the correct choice for dry survey areas.
