Which action can help in detecting the presence of explosive gases?

• A. Using a handheld detection device
• B. Relying solely on smell
• C. Inspections once a month
• D. Fitting all manholes with locks

Answer: (A)

Using a handheld detection device is essential for accurately detecting the presence of explosive gases in wastewater collection systems. These devices are designed to identify specific hazardous gases by measuring their concentrations in the air. They provide real-time data and can alert operators to dangerous levels, improving safety and facilitating timely interventions. Relying solely on smell is not a reliable method for detecting explosive gases, as many gases, such as methane, are odorless and can only be sensed when they reach certain concentrations. Inspections conducted once a month may not be frequent enough to ensure ongoing safety, especially in environments where gas accumulation can change rapidly. Fitting manholes with locks can aid in security but does not provide a means for gas detection or monitoring, thus failing to address the need for identifying explosive atmospheres effectively.
