The Art of Reading Smoke for Rapid Decision Making
The Art of Reading Smoke for Rapid Decision Making Dave Dodson teaches the art of reading smoke. This is an important skill since fighting fires in the year 2006 and beyond will be unlike the fires we fought in the 1900’s. Composites, lightweight construction, engineered structures, and unusual fuels will cause hostile fires to burn hotter, faster, and less predictable. Concept #1: “Smoke” is FUEL! Firefighters use the term “smoke” when addressing the solids, aerosols, and gases being produced by the hostile fire. Soot, dust, and fibers make up the solids. Aerosols are suspended liquids such as water, trace acids, and hydrocarbons (oil). Gases are numerous in smoke – mass quantities of Carbon Monoxide lead the list. Concept #2: The Fuels have changed: The contents and structural elements being burned are of LOWER MASS than previous decades. These materials are also more synthetic than ever. Concept #3: The Fuels have triggers There are “Triggers” for Hostile Fire Events. Flash point triggers a smoke explosion. Fire Point triggers rapid fire spread, ignition temperature triggers auto ignition, Backdraft, and Flashover. Hostile fire events (know the warning signs): Flashover: The classic American Version of a Flashover is the simultaneous ignition of fuels within a compartment due to reflective radiant heat – the “box” is heat saturated and can’t absorb any more. The British use the term Flashover to describe any ignition of the smoke cloud within a structure. Signs: Turbulent smoke, rollover, and auto-ignition outside the box. Backdraft: A “true” backdraft occurs when oxygen is introduced into an O2 deficient environment that is charged with gases (pressurized) at or above their ignition temperature. -

MILWAUKEE FIRE DEPARTMENT Operational Guidelines Approved by: Chief Mark Rohlfing 2012 FORWARD The purpose of these operational guidelines is to make clear expectations for company performance, safety, and efficiency, eliminating the potential for confusion and duplication of effort at the emergency scene. It is understood that extraordinary situations may dictate a deviation from these guidelines. Deviation can only be authorized by the officer/acting officer of an apparatus or the incident commander. Any deviation must be communicated over the incident talk group. The following guidelines are meant to clarify best operational practices for the MFD. They are not intended to be all-inclusive and are designed to be updated as necessary. They are guidelines for you to use. However, there will be no compromise on issues of safety, chain of command, correct gear usage, or turnout times (per NFPA 1710). These operating guidelines will outline tool and task responsibilities for the specific riding positions on responding units. While the title of each riding position and the assignments that follow may not always seem to be a perfect pairing, the tactical advantage of knowing where each member is supposed to be operating at a given assignment will provide for increased accountability and increased effectiveness while performing our response duties. Within the guidelines, you will see run-type specific (and in some cases, arrival order specific) tool and task assignments. On those responses listing a ‘T (or R)’ as the response unit, the Company will be uniformly listed as ‘Truck’ for continuity. The riding positions are as follows: ENGINE RIDING POSITIONS OFFICER HEO NOZZLE FF BACKUP FF TRUCK RIDING POSITIONS OFFICER HEO VENT FF FORCE FF SAFETY If you see something that you believe impacts our safety, it is your duty to report it to your superior Officer immediately. -

Occupational Risks and Hazards Associated with Firefighting by Laura Walker A report submitted in partial fulfillment of the requirements for the degree of Master of Science Industrial Hygiene Distance Learning / Professional Track Montana Tech of the University of Montana 2016 This page intentionally left blank. 1 Abstract Annually about 100 firefighters die in the line duty, in the United States. Firefighters know it is a hazardous occupation. Firefighters know the only way to reduce the number of deaths is to change the way the firefighter (FF) operates. Changing the way a firefighter operates starts by utilizing traditional industrial hygiene tactics, anticipating, recognizing, evaluating and controlling the hazard. Basic information and history of the fire service is necessary to evaluate FF hazards. An electronic survey was distributed to FFs. The first question was, “What are the health and safety risks of a firefighter?” Hypothetically heart attacks and new style construction would rise to the top of the survey data. -
