Home Fires
Every year nearly 4,000 Americans die in home fires and more than 25,000
are injured. Children and the elderly are especially at risk in home fires because
they are less able to escape when fire strikes. You can improve the chances
that your family will survive a home fire by making sure that they can escape
quickly if necessary.
Smoke Alarms are Life Savers
The primary fire safety strategy for any home is to warn the occupants early. The
best way to get the earliest warning of danger is by installing enough smoke
alarms. Homes should have a smoke alarm near the bedrooms, but not so close
to the kitchen that you have problems with alarms from cooking. It's a good idea to
have a smoke alarm in each bedroom, especially if you sleep with the door
closed.
Planning Your Escape
The other part of the fire safety plan is for everyone to get out quickly. When you
are awakened in the middle of the night to a fire, your thinking may be confused,
so it is important that you practice your escape plan ahead of time. That way,
your whole family will know what to do. Manufactured homes have more ways to
escape than most other homes. There are always two doors, and every bedroom
has an emergency escape window. Make sure that everyone knows how to open
the emergency windows so no time is wasted when fire strikes. These windows
are labeled with operating instructions. Everyone in the family, as well as frequent
visitors and babysitters, should practice the escape plan, including opening the
escape windows.
Can You Beat the Clock?
Most people do not realize how quickly fires can grow. A home fire can become a
killer in as little as 3 minutes. Can your family get out this fast? Consider that it
may take one minute for the smoke alarm to sound and for you to recognize the
danger. If you have young children or you are elderly and move more slowly, you
may need another minute to get ready. This leaves only 1 minute for you all to get
to an exit, open it, and get out. By practicing your escape, you can make every
second count.
Steps to a Safe Escape
1.Have at least two working smoke alarms, test them monthly.
2.Plan two ways out of every room.
3.Practice your escape plan twice yearly.
4.Practice crawling low under smoke.
5.Have a pre-arranged meeting place outside your home.
6.Call the fire department from a neighbor's home.
7.Once outside, stay out.
.Carbon Monoxide
Physical Characteristics and Sources
Carbon monoxide is a colorless, odorless, tasteless gas. It occurs
naturally in the air as the result of incomplete combustion processes,
such as forest fires, the oxidation of methane, and other natural
processes. Natural background concentrations are about .05 - .15
parts per million. This is an insignificant level compared to
concentrations found in urban environments, where CO is by far the
most abundant pollutant in the atmosphere. Urban atmospheres contain
about 100 times as much CO as any other pollutant. Urban carbon
monoxide is produced primarily by motor vehicles. Another significant
source of CO is emissions from wood burning stoves and
fireplaces. The remaining emissions originate from industrial and
construction equipment, air craft, point sources, space heating and
railroad sources.
Because motor vehicle emissions are the major source of CO, daily
concentration peaks coincide with morning and evening rush hours. The
worst carbon monoxide problems are found where large numbers of
slow moving cars congregate, such as in large parking lots or during
traffic jams. CO can thus temporarily accumulate to harmful levels,
especially in calm weather during autumn and winter. CO problems are
worst in winter because: 1) cold weather makes motor vehicles run less
efficiently; 2) wood burning emissions for space heating are increased;
and 3) on winter nights a strong inversion layer may develop near the
ground, trapping pollutants.
Health and Welfare Effects
Carbon monoxide affects the central nervous system by depriving the
body of oxygen. Tests of automobile drivers show exposure to carbon
monoxide can impair a driver's judgment and ability to respond rapidly
in traffic.
Carbon monoxide enters the body through the lungs, where it is
absorbed by the bloodstream and combines with hemoglobin, the
substance that carries oxygen to the cells. Hemoglobin that is bound
with CO is called carboxyhemoglobin (COHb). Hemoglobin binds
approximately 240 times more readily with CO than with oxygen. Thus,
the amount of oxygen being distributed throughout the body by the
bloodstream is reduced in CO's presence. Blood laden with CO can
weaken heart contractions, lowering the volume of blood distributed to
various parts of the body. It can also significantly reduce a healthy
person's ability to perform manual tasks, such as working, jogging and
walking. A life-threatening situation exists in patients with heart disease,
who are unable to compensate for the oxygen loss. The millions of
people in the U.S. suffering from angina pectoris (a heart disease
characterized by brief spasmodic attacks of chest pain due to
insufficient oxygen levels in the heart muscles) are especially
susceptible.
EPA has concluded that the following groups may be particularly
sensitive to exposures of CO: Angina patients, individuals with other
types of cardiovascular disease, persons with chronic obstructive
pulmonary disease, anemic individuals, fetuses, and pregnant
women. Concern also exists for healthy children because of increased
oxygen requirements that result from their higher metabolism rate.
![]() Record Type: Interpretation
Standard Number: 1910.134(g)(4)
Subject: Two-in/two-out rule for interior structural fire fighting.
Information Date: 11/13/1998
November 13, 1998
Mark Schultz, GFD
Senior Fire Inspector
Gallatin Fire Department
119 Foster Street
Gallatin, TN 37066-3209
Dear Mr. Schultz:
This is in response to your letter of April 30, addressed to Mr. John B. Miles asking for
interpretations of the new Respiratory Protection Standard, 29 CFR 1910.134. You had
specific questions regarding the Occupational Safety and Health Administration's (OSHA's)
two in/two out requirement. We apologize for the long delay of this response. As you may
be aware, Federal OSHA does not have jurisdiction over employees of State and local
governments, including firefighters. However, the State of Tennessee does cover public
sector employees under its OSHA-approved occupational safety and health State plan.
Tennessee has adopted a standard identical to the Federal respiratory protection
standard. While the State may interpret its standard differently from Federal OSHA, the
interpretations must be at least as effective as the Federal interpretations. You may wish
to contact the Tennessee Department of Labor concerning its enforcement of the
respiratory protection standard. The address is:
Michael E. Magill, Commissioner
Tennessee Department of Labor
710 James Robertson Parkway
Nashville, Tennessee 37243-5078
Telephone: (615) 741-2582
We are providing Commissioner Magill with a copy of this letter.
You had several questions asking if the two in/two out rule for interior structural fire
fighting was a one for one policy, specifically if four people were in did that mean that
four people had to stand by, if eleven people were inside, did that mean eleven people
had to be on stand by and so on. No, the two in/two out rule may not be interpreted as
four in/four out, eight in/eight out. There must always be at least two firefighters
stationed outside during interior structural firefighting, prepared to enter if necessary to
rescue the firefighters inside. However, the incident commander has the flexibility to
determine whether more than two outside firefighters are necessary when more than two
firefighters go inside. In a situation where the burning structure is very large, additional
outside firefighters may be warranted to ensure effective assistance and rescue. For
example, where the firefighting involves entry from different locations or levels, two
outside fire fighters may have to be stationed at each point of entry.
You also asked whether standby personnel had to wait for additional standby personnel
before entering to attempt a rescue of fire fighters in a structural fire. No. There is an
explicit exemption in the Respiratory Protection Standard that if life is in jeopardy, the
two-in/two out requirement is waived. The incident commander and the firefighters at the
scene must decide whether the risks posed by entering an interior structural fire prior to
the assembly of at least four firefighters is outweighed by the need to rescue victims who
are at risk of death or serious physical harm. There is no violation of the standard under
rescue circumstances.
Please note that on August 3, 1998, OSHA published Questions and Answers on the
Respiratory Protection Standard. This 79 page document contains guidance on
respiratory protection. There are many questions in this document on respiratory
protection and firefighting issues and may help you develop a thorough respiratory
protection program. In addition, OSHA has recently published the Compliance Directive,
CPL 2-0.120, an inspection procedure document for the OSHA field offices, and the Small
Entity Compliance Guide to assist small employers in complying with the respiratory
standard. All these documents can be found on the Internet at the OSHA Home Page at
http://www.osha.gov.
Should you require any additional information on this matter, please, feel free to contact
our Office of Health Compliance Assistance at (202) 693-2190.
Sincerely,
Richard E. Fairfax
Acting Director
Directorate of Compliance Programs
