1. Lightweight wood trusses have received substantial attention in the last several years, including an alert issued by NIOSH in 2005. Although this is somewhat dated, the message still applies for today's fire service. Please discuss the dangers of lightweight wood trusses and how they apply in your community. What has your department done to identify and prepare for these hazards from a preplanning and operational perspective?

2. Describe how a lightweight wood truss will fail when exposed to a fire.

Your response should be at least 200 words in length. You are required to use at least your textbook as source material for your response. All sources used, including the textbook, must be referenced; paraphrased and quoted material must have accompanying citations.

3. You are a firefighter assigned to protect the exteriors of two old wood frame apartment buildings located on both sides of an alley way. Both of the apartment structures have exterior sidewall asphalt siding shingles. What are your concerns? Please discuss.
