Attachment D <br />sides of existing roads that lead up to the Capital Hill area <br />(Continued) <br />Concern Reality #2 <br /> The impact upon the timely response of additional fire response vehicles on major <br />medical emergencies and fire incidents. <br /> For structure fires, NFPA 1710 calls for a minimum firefighting force of 4 to arrive <br />within 5 minutes, 90% of the time. This means we need two fire engines on scene in <br />that time allowance. <br /> Additionally, OR-OSHA requires a minimum of one 2 person entry team and one 2 <br />person rescue team to be assembled before entry into an IDLH (Immediately <br />Dangerous to Life and Health) atmosphere except for situations where a known <br />victim is inside the structure and rescue needs to be performed to save a life. <br /> NFPA 1710 fu <br />within 9 minutes, 90% of the time. Our first alarm assignment for a residential <br />structure fire includes 4 engine company(12 persons total), 1 truck company(3 <br />persons total), 1 medic unit(2 persons total) and 2 chief officers(2 total). <br /> Given the severely restricted access to the area, in all likelihood the truck company <br />would not be able to physically drive to the scene. This means the Incident <br />Commander would need to determine whether to have the crew from the truck park <br />at the most out of the way place and walk in on foot or send the truck away and call <br />for another engine company. Either way the truck company crew of 3 would be out <br />of the fire fight. <br />Fire Department Comments Submitted By <br />Deputy fire Marshal Mark Dahl <br />Page 381 <br /> <br />
