How should firing troughs be oriented relative to the audience?

• A. With the narrow side facing the audience
• B. With the wide side facing the audience
• C. Perpendicular to the audience
• D. Facing away from the audience

Answer: (A)

The main idea is to control where the fire, sparks, and debris go to protect spectators. When the trough’s narrow side faces the audience, the discharge is more contained toward the length of the trough and directed away from the crowd, reducing the chance of hot particles reaching people. If the wide side faced the audience, the blast and embers would spread over a larger arc and aumentar risk to spectators. Orienting the trough perpendicular to the audience or facing away from them doesn’t reliably shield the crowd and can misdirect the effect. So, having the narrow edge toward the audience keeps the show safer by limiting exposure while directing the output along the trough’s length.
