What is a typical first reaction when formaldehyde exposure is detected above normal levels?

• A. Turn on ventilation
• B. Leave the area immediately
• C. Continue working
• D. Perform a headcount

Answer: (A)

The correct response involves activating the ventilation system when formaldehyde exposure is detected above normal levels. This action is crucial because proper ventilation helps to dilute and remove hazardous airborne contaminants, thereby reducing the concentration of formaldehyde in the environment. Enhancing airflow not only helps protect those working in the area from potential health hazards but also ensures compliance with safety regulations regarding exposure limits.

While it might also seem logical to leave the area immediately, doing so might not address the ongoing risk to others who remain. Simply continuing to work would expose individuals to harmful levels of the chemical, potentially leading to acute health issues. Performing a headcount would also be ineffective in mitigating the risk of exposure and could distract from the urgent need to improve ventilation conditions. Therefore, turning on the ventilation system is the most appropriate and effective first reaction in this scenario.
