OBJECTIVES To examine exposure-response relationships between surrogates of firefighting exposure and select outcomes among previously studied US career firefighters. METHODS Eight cancer and four non-cancer outcomes were examined using conditional logistic regression. Incidence density sampling was used to match each case to 200 controls on attained age. Days accrued in firefighting assignme...

In this paper, in order to effectively respond and rescue lives a disaster scene, the site command center design smart firefighting helmet exchange information make accurate decisions, propose an algorithm that can transmit receive video audio through it. do. Recently, there have been cases which rapid response has not made due situation inside delay communication. So, we communication of voice...

Let Gλ be the graph whose vertices are points of a planar Poisson process of density λ, with vertices adjacent if they are within distance 1. A “fire” begins at some vertex and spreads to all neighbors in discrete steps; in the meantime f vertices can be deleted at each time-step. Let fλ be the least f such that, with probability 1, any fire on Gλ can be stopped in finite time. We show that fλ ...

Among the approximately 1.1 million firefighters in the United States (of whom about 70% are volunteers and 30% are paid career personnel), about 100 die each year in the line of duty.1 With the exception of 2001, when 344 firefighters died as a result of the events of September 11 at the World Trade Center in New York City, the number of deaths per year has stayed relatively steady, even thoug...

Since the Firefighting Facilities Act mandated installation of residential firefighting systems, incidence deaths in house fires has been lowered. Although there is a regulation requiring facilities homes according to Act, no penalty provision. Therefore, new regulations should be established and building owners report on facilities. If fire occurs living room independent alarm-type detector op...

Unwanted fire alarms of firefighting facilities is the cause reducing reliability for occupants. Accordingly, it intended to review theoretical background unwanted and investigate opinions firefighting-related workers on alarms. There were 282 participants, all whom participated online. The majority respondents those who had a lot experience could distinguish between reports. In addition, in de...
