Which of the following is a common method for vapor control during a HazMat incident?

Ventilation or fanning is an effective common method for vapor control during a hazardous materials incident. This technique involves actively moving air into or out of the area to dilute and disperse harmful vapors that might be present in the environment. By promoting airflow, vapors are less likely to accumulate, reducing the risk of inhalation hazards for responders and nearby individuals.

This method is particularly useful in confined spaces where vapors can concentrate quickly, as it helps to lower the levels of contaminants to safer concentrations. Additionally, the introduction of fresh air can help to mitigate flammability risks associated with certain vapors.

In contrast, sealing off the area with barriers may isolate the contaminants but does not address the need to manage vapor concentrations. Deploying chemical neutralizers is more suited to dealing with spills and doesn't specifically target vapor control. Covering the contaminated area with tarps can prevent further spread of materials but does not effectively manage vapor dispersion.
