When should a gas detector or indicator be used?

• A. When entering every other manhole.
• B. Before entering all manholes.
• C. During the summer only.
• D. Only by the supervisor.

Answer: (B)

A gas detector or indicator is essential for ensuring safety when entering manholes, as these confined spaces can contain harmful gases such as methane, hydrogen sulfide, or other toxic fumes. Using a gas detector before entering all manholes is crucial because it allows workers to assess the atmosphere and ensure that it is safe for entry. This proactive measure helps prevent exposure to hazardous gases that could lead to serious health risks or fatalities. The requirement to use a gas detector before entering all manholes underscores the importance of consistently monitoring air quality in confined spaces, rather than only in specific situations or at the discretion of certain individuals. This consistent approach fosters a culture of safety and provides all workers the protection they need when working in potentially dangerous environments.
