If flex-pipe (flex-hose) is used for hot asphalt, where must the end extend?

• A. Above the wall and onto the roof area
• B. Below the wall
• C. On the ground
• D. Inside the attic

Answer: (A)

When using a flex-hose to transfer hot asphalt, you want to direct the heat, fumes, and any drips away from the interior of the building and from occupied spaces. Extending the end above the wall and onto the roof area accomplishes this by placing the outlet at roof level, so vapors and hot material rise away from walls, openings, and attic spaces. This reduces the chance that fumes or asphalt will enter living areas or crawl spaces and helps keep the work area safer for your crew and nearby materials. If the end were kept below the wall, fumes and heat could vent into the eaves, ceilings, or interior spaces, increasing inhalation risk and fire hazard. On the ground, drips and runoff could create slips, spills, or damage to exterior surfaces, and inside the attic would expose the space to heat and fumes, which is unsafe and against typical ventilation practices. Extending the end onto the roof area avoids these issues by maintaining a clear, outside venting path.
