No. 12-71 (36 FR 8754), 8-76 (41 FR 25059), 9-83 (48 FR 35736), or 1-90
(55 FR 9033), as applicable.
Sec. 1910.35 Definitions.
As used in this subpart.
(a) Means of egress. A means of egress is a continuous and
unobstructed way of exit travel from any point in a building or
structure to a public way and consists of three separate and distinct
parts: the way of exit access, the exit, and the way of exit discharge.
A means of egress comprises the vertical and horizontal ways of travel
and shall include intervening room spaces, doorways, hallways,
corridors, passageways, balconies, ramps, stairs, enclosures, lobbies,
escalators, horizontal exits, courts, and yards.
(b) Exit access. Exit access is that portion of a means of egress
which leads to an entrance to an exit.
(c) Exit. Exit is that portion of a means of egress which is
separated from all other spaces of the building or structure by
construction or equipment as required in this subpart to provide a
protected way of travel to the exit discharge.
(d) Exit discharge. Exit discharge is that portion of a means of
egress between the termination of an exit and a public way.
(e) Low hazard contents. Low hazard contents shall be classified as
those of such low combustibility that no self- propagating fire therein
can occur and that consequently the only probable danger requiring the
use of emergency exits will be from panic, fumes, or smoke, or fire from
some external source.
(f) High-hazard contents. High-hazard contents shall be classified
as those which are liable to burn with extreme rapidity or from which
poisonous fumes or explosions are to be feared in the event of fire.
(g) Ordinary hazard contents. Ordinary hazard contents shall be
classified as those which are liable to burn with moderate rapidity and
to give off a considerable volume of smoke but from which neither
poisonous fumes nor explosions are to be feared in case of fire.
(h) Approved. For the purpose of this subpart approved shall mean
listed or approved equipment by a nationally recognized testing
laboratory. Refer to Sec. 1910.155(c)(3)(iv)(A) for definition of
listed, and Sec. 1910.7 for nationally recognized testing laboratory.
(i) Emergency action plan means a plan for a workplace, or parts
thereof, describing what procedures the employer and employees must take
to ensure employee safety from fire or other emergencies.
(j) Emergency escape route means the route that employees are
directed to follow in the event they are required to evacuate the
workplace or seek a designated refuge area.

Sec. 1910.36 General requirements.
(a) Application. This subpart contains general fundamental
requirements essential to providing a safe means of egress from fire and
like emergencies. Nothing in this subpart shall be construed to prohibit
a better type of building construction, more exits, or otherwise safer
conditions than the minimum requirements specified in this subpart.
Exits from vehicles, vessels, or other mobile structures are not covered
by this subpart.
(b) Fundamental requirements. (1) Every building or structure, new
or old, designed for human occupancy shall be provided with exits
sufficient to permit the prompt escape of occupants in case of fire or
other emergency. The design of exits and other safeguards shall be such
that reliance for safety to life in case of fire or other emergency will
not depend solely on any single safeguard; additional safeguards shall
be provided for life safety in case any single safeguard is ineffective
due to some human or mechanical failure.
(2) Every building or structure shall be so constructed, arranged,
equipped, maintained, and operated as to avoid undue danger to the lives
and safety of its occupants from fire, smoke, fumes, or resulting panic
during the period of time reasonably necessary for escape from the
building or structure in case of fire or other emergency.
(3) Every building or structure shall be provided with exits of
kinds, numbers, location, and capacity appropriate to the individual
building or structure, with due regard to the character of the
occupancy, the number of persons exposed, the fire protection available,
and the height and type of construction of the building or structure, to
afford all occupants convenient facilities for escape.
(4) In every building or structure exits shall be so arranged and
maintained as to provide free and unobstructed egress from all parts of
the building or structure at all times when it is occupied. No lock or
fastening to prevent free escape from the inside of any building shall
be installed except in mental, penal, or corrective institutions where
supervisory personnel is continually on duty and effective provisions
are made to remove occupants in case of fire or other emergency.
(5) Every exit shall be clearly visible or the route to reach it
shall be conspicuously indicated in such a manner that every occupant of
every building or structure who is physically and mentally capable will
readily know the direction of escape from any point, and each path of
escape, in its entirety, shall be so arranged or marked that
the way to a place of safety outside is unmistakable. Any doorway or
passageway not constituting an exit or way to reach an exit, but of such
a character as to be subject to being mistaken for an exit, shall be so
arranged or marked as to minimize its possible confusion with an exit
and the resultant danger of persons endeavoring to escape from fire
finding themselves trapped in a dead-end space, such as a cellar or
storeroom, from which there is no other way out.
(6) In every building or structure equipped for artificial
illumination, adequate and reliable illumination shall be provided for
all exit facilities.
(7) In every building or structure of such size, arrangement, or
occupancy that a fire may not itself provide adequate warning to
occupants, fire alarm facilities shall be provided where necessary to
warn occupants of the existence of fire so that they may escape, or to
facilitate the orderly conduct of fire exit drills.
(8) Every building or structure, section, or area thereof of such
size, occupancy, and arrangement that the reasonable safety of numbers
of occupants may be endangered by the blocking of any single means of
egress due to fire or smoke, shall have at least two means of egress
remote from each other, so arranged as to minimize any possibility that
both may be blocked by any one fire or other emergency conditions.
(9) Compliance with this subpart shall not be construed as
eliminating or reducing the necessity for other provisions for safety of
persons using a structure under normal occupancy conditions, nor shall
any provision of the subpart be construed as requiring or permitting any
condition that may be hazardous under normal occupancy conditions.
(c) Protection of employees exposed by construction and repair
operations. (1) No building or structure under construction shall be
occupied in whole or in part until all exit facilities required for the
part occupied are completed and ready for use.
(2) No existing building shall be occupied during repairs or
alterations unless all existing exits and any existing fire protection
are continuously maintained, or in lieu thereof other measures are taken
which provide equivalent safety.
(3) No flammable or explosive substances or equipment for repairs or
alterations shall be introduced in a building of normally low or
ordinary hazard classification while the building is occupied, unless
the condition of use and safeguards provided are such as not to create
any additional danger or handicap to egress beyond the normally
permissible conditions in the building.
(d) Maintenance. (1) Every required exit, way of approach thereto,
and way of travel from the exit into the street or open space, shall be
continuously maintained free of all obstructions or impediments to full
instant use in the case of fire or other emergency.
(2) Every automatic sprinkler system, fire detection and alarm
system, exit lighting, fire door, and other item of equipment, where
provided, shall be continuously in proper operating condition.
Sec. 1910.37 Means of egress, general.
(a) Permissible exit components. An exit shall consist only of the
approved components. Exit components shall be constructed as an integral
part of the building or shall be permanently affixed thereto.
(b) Protective enclosure of exits. When an exit is protected by
separation from other parts of the building the separating construction
shall meet the following requirements.
(1) The separation shall have at least a 1-hour fire resistance
rating when the exit connects three stories or less. This applies
whether the stories connected are above or below the story at which exit
(2) The separation shall have at least a 2-hour fire resistance
rating when the exit connects four or more stories, whether above or
below the floor of discharge. It shall be constructed of noncombustible
materials, and shall be supported by construction having at least a 2-
hour fire resistance rating.
(3) Any opening therein shall be protected by an approved self-
closing fire door.
(4) Openings in exit enclosures shall be confined to those necessary
for access to the enclosure from normally occupied spaces and for egress
from the enclosure.
(c) Width and capacity of means of egress. (1) The capacity in
number of persons per unit of exit width for approved components of
means of egress shall be as follows:
(i) Level Egress Components (including Class A Ramps) 100 persons.
(ii) Inclined Egress Components (including Class B Ramps) 60
(iii) A ramp shall be designated as Class A or Class B in accordance
with the following Table E-1:
Class A Class B
Width........................... 44 inches and 30 to 44 inches.
Slope........................... 1 to 1\3/16\ 1\3/16\ to 2
inches in 12 inches in 12
Maximum height between landings. No limit.......... 12 feet.
(2) Means of egress shall be measured in units of exit width of 22
inches. Fractions of a unit shall not be counted, except that 12 inches
added to one or more full units shall be counted as one-half a unit of
(3) Units of exit width shall be measured in the clear at the
narrowest point of the means of egress except that a handrail may
project inside the measured width on each side not more than 5 inches
and a stringer may project inside the measured width not more than 1\1/
2\ inches. An exit or exit access door swinging into an aisle or
passageway shall not restrict the effective width thereof at any point
during its swing to less than the minimum widths hereafter specified.
(d) Egress capacity and occupant load. (1) The capacity of means of
egress for any floor, balcony, tier, or other occupied space shall be
sufficient for the occupant load thereof. The occupant load shall be the
maximum number of persons that may be in the space at any time.
(2) Where exits serve more than one floor, only the occupant load of
each floor considered individually need be used in computing the
capacity of the exits at that floor, provided that exit capacity shall
not be decreased in the direction of exit travel.
(e) Arrangement of exits. When more than one exit is required from a
story, at least two of the exits shall be remote from each other and so
arranged as to minimize any possibility that both may be blocked by any
one fire or other emergency condition.
(f) Access to exits. (1) Exits shall be so located and exit access
shall be so arranged that exits are readily accessible at all times.
Where exits are not immediately accessible from an open floor area, safe
and continuous passageways, aisles, or corridors leading directly to
every exit and so arranged as to provide convenient access for each
occupant to at least two exits by separate ways of travel, except as a
single exit or limited dead ends are permitted by other provisions of
this subpart, shall be maintained.
(2) A door from a room to an exit or to a way of exit access shall
be of the side-hinged, swinging type. It shall swing with exit travel
when the room is occupied by more than 50 persons or used for a high
(3) In no case shall access to an exit be through a bathroom, or
other room subject to locking, except where the exit is required to
serve only the room subject to locking.
(4) Ways of exit access and the doors to exits to which they lead
shall be so designed and arranged as to be clearly recognizable as such.
Hangings or draperies shall not be placed over exit doors or otherwise
so located as to conceal or obscure any exit. Mirrors shall not be
placed on exit doors. Mirrors shall not be placed in or adjacent to any
exit in such a manner as to confuse the direction of exit.
(5) Exit access shall be so arranged that it will not be necessary
to travel toward any area of high hazard occupancy in order to reach the
nearest exit, unless the path of travel is effectively shielded from the
high hazard location by suitable partitions or other physical barriers.
(6) The minimum width of any way of exit access shall in no case be
less than 28 inches. Where a single way of exit access leads to an exit,
its capacity in terms of width shall be at least equal to the required
capacity of the exit to
which it leads. Where more than one way of exit access leads to an exit,
each shall have a width adequate for the number of persons it must
(g) Exterior ways of exit access. (1) Access to an exit may be by
means of any exterior balcony, porch, gallery, or roof that conforms to
the requirements of this section.
(2) Exterior ways of exit access shall have smooth, solid floors,
substantially level, and shall have guards on the unenclosed sides.
(3) Where accumulation of snow or ice is likely because of the
climate, the exterior way of exit access shall be protected by a roof,
unless it serves as the sole normal means of access to the rooms or
spaces served, in which case it may be assumed that snow and ice will be
regularly removed in the course of normal occupancy.
(4) A permanent, reasonably straight path of travel shall be
maintained over the required exterior way of exit access. There shall be
no obstruction by railings, barriers, or gates that divide the open
space into sections appurtenant to individual rooms, apartments, or
other uses. Where the Assistant Secretary of Labor or his duly
authorized representative finds the required path of travel to be
obstructed by furniture or other movable objects, he may require that
they be fastened out of the way or he may require that railings or other
permanent barriers be installed to protect the path of travel against
(5) An exterior way of exit access shall be so arranged that there
are no dead ends in excess of 20 feet. Any unenclosed exit served by an
exterior way of exit access shall be so located that no part of the exit
extends past a vertical plane 20 feet and one-half the required width of
the exit from the end of and at right angles to the way of exit access.
(6) Any gallery, balcony, bridge, porch, or other exterior exit
access that projects beyond the outside wall of the building shall
comply with the requirements of this section as to width and
(h) Discharge from exits. (1) All exits shall discharge directly to
the street, or to a yard, court, or other open space that gives safe
access to a public way. The streets to which the exits discharge shall
be of width adequate to accommodate all persons leaving the building.
Yards, courts, or other open spaces to which exits discharge shall also
be of adequate width and size to provide all persons leaving the
building with ready access to the street.
(2) Stairs and other exits shall be so arranged as to make clear the
direction of egress to the street. Exit stairs that continue beyond the
floor of discharge shall be interrupted at the floor of discharge by
partitions, doors, or other effective means.
(i) Headroom. Means of egress shall be so designed and maintained as
to provide adequate headroom, but in no case shall the ceiling height be
less than 7 feet 6 inches nor any projection from the ceiling be less
than 6 feet 8 inches from the floor.
(j) Changes in elevation. Where a means of egress is not
substantially level, such differences in elevation shall be negotiated
by stairs or ramps.
(k) Maintenance and workmanship. (1) Doors, stairs, ramps, passages,
signs, and all other components of means of egress shall be of
substantial, reliable construction and shall be built or installed in a
(2) Means of egress shall be continuously maintained free of all
obstructions or impediments to full instant use in the case of fire or
(3) Any device or alarm installed to restrict the improper use of an
exit shall be so designed and installed that it cannot, even in cases of
failure, impede or prevent emergency use of such exit.
(l) Furnishings and decorations. (1) No furnishings, decorations, or
other objects shall be so placed as to obstruct exits, access thereto,
egress therefrom, or visibility thereof.
(2) No furnishings or decorations of an explosive or highly
flammable character shall be used in any occupancy.
(m) Automatic sprinkler systems. All automatic sprinkler systems
shall be continuously maintained in reliable operating condition at all
times, and such periodic inspections and tests shall be made as are
necessary to assure proper maintenance.
(n) Fire alarm signaling systems. The employer shall assure that
fire alarm signaling systems are maintained and tested in accordance
with the requirements of Sec. 1910.165(d).
(o) Fire retardant paints. Fire retardant paints or solutions shall
be renewed at such intervals as necessary to maintain the necessary
flame retardant properties.
(q) Exit marking. (1) Exits shall be marked by a readily visible
sign. Access to exits shall be marked by readily visible signs in all
cases where the exit or way to reach it is not immediately visible to
(2) Any door, passage, or stairway which is neither an exit nor a
way of exit access, and which is so located or arranged as to be likely
to be mistaken for an exit, shall be identified by a sign reading ``Not
an Exit'' or similar designation, or shall be identified by a sign
indicating its actual character, such as ``To Basement,'' ``Storeroom,''
``Linen Closet,'' or the like.
(3) Every required sign designating an exit or way of exit access
shall be so located and of such size, color, and design as to be readily
visible. No decorations, furnishings, or equipment which impair
visibility of an exit sign shall be permitted, nor shall there be any
brightly illuminated sign (for other than exit purposes), display, or
object in or near the line of vision to the required exit sign of such a
character as to so detract attention from the exit sign that it may not
(4) Every exit sign shall be distinctive in color and shall provide
contrast with decorations, interior finish, or other signs.
(5) A sign reading ``Exit'', or similar designation, with an arrow
indicating the directions, shall be placed in every location where the
direction of travel to reach the nearest exit is not immediately
(6) Every exit sign shall be suitably illuminated by a reliable
light source giving a value of not less than 5 foot-candles on the

Appendix to Subpart E of Part 1910--Means of Egress
This appendix serves as a nonmandatory guideline to assist employers
in complying with the appropriate requirements of subpart E.
Sec. 1910.38 Employee emergency plans.
1. Emergency action plan elements. The emergency action plan should
address emergencies that the employer may reasonably expect in the
workplace. Examples are: fire; toxic chemical releases; hurricanes;
tornadoes; blizzards; floods; and others. The elements of the emergency
action plan presented in paragraph 1910.38(a)(2) can be supplemented by
the following to more effectively achieve employee safety and health in
an emergency. The employer should list in detail the procedures to be
taken by those employees who have been selected to remain behind to care
for essential plant operations until their evacuation becomes absolutely
necessary. Essential plant operations may include the monitoring of
plant power supplies, water supplies, and other essential services which
cannot be shut down for every emergency alarm. Essential plant
operations may also include chemical or manufacturing processes which
must be shut down in stages or steps where certain employees must be
present to assure that safe shut down procedures are completed.
The use of floor plans or workplace maps which clearly show the
emergency escape routes should be included in the emergency action plan.
Color coding will aid employees in determining their route assignments.
The employer should also develop and explain in detail what rescue
and medical first aid duties are to be performed and by whom. All
employees are to be told what actions they are to take in these
emergency situations that the employer anticipates may occur in the
2. Emergency evacuation. At the time of an emergency, employees
should know what type of evacuation is necessary and what their role is
in carrying out the plan. In some cases where the emergency is very
grave, total and immediate evacuation of all employees is necessary. In
other emergencies, a partial evacuation of nonessential employees with a
delayed evacuation of others may be necessary for continued plant
operation. In some cases, only those employees in the immediate area of
the fire may be expected to evacuate or move to a safe area such as when
a local application fire suppression system discharge employee alarm is
sounded. Employees must be sure that they know what is expected of them
in all such emergency possibilities which have been planned in order to
provide assurance of their safety from fire or other emergency.
The designation of refuge or safe areas for evacuation should be
determined and identified in the plan. In a building divided into fire
zones by fire walls, the refuge area may still be within the same
building but in a different zone from where the emergency occurs.
Exterior refuge or safe areas may include parking lots, open fields
or streets which are located away from the site of the emergency and
which provide sufficient space to accommodate the employees. Employees
should be instructed to move away from the exit discharge doors of the
building, and to avoid congregating close to the building where they may
hamper emergency operations.
3. Emergency action plan training. The employer should assure that
an adequate number of employees are available at all times during
working hours to act as evacuation wardens so that employees can be
swiftly moved from the danger location to the safe areas. Generally, one
warden for each twenty employees in the workplace should be able to
provide adequate guidance and instruction at the time of a fire
emergency. The employees selected or who volunteer to serve as wardens
should be trained in the complete workplace layout and the various
alternative escape routes from the workplace. All wardens and fellow
employees should be made aware of handicapped employees who may need
extra assistance, such as using the buddy system, and of hazardous areas
to be avoided during emergencies. Before leaving, wardens should check
rooms and other enclosed spaces in the workplace for employees who may
be trapped or otherwise unable to evacuate the area.
After the desired degree of evacuation is completed, the wardens
should be able to account for or otherwise verify that all employees are
in the safe areas.
In buildings with several places of employment, employers are
encouraged to coordinate their plans with the other employers in the
building. A building-wide or standardized plan for the whole building is
acceptable provided that the employers inform their respective employees
of their duties and responsibilities under the plan. The standardized
plan need not be kept by each employer in the multi-employer building,
provided there is an accessible location within the building where the
plan can be reviewed by affected employees. When multi-employer
building-wide plans are not feasible, employers should coordinate their
plans with the other employers within the building to assure that
conflicts and confusion are avoided during times of emergencies. In
multi-story buildings where more than one employer is on a single floor,
it is essential that these employers coordinate their plans with each
other to avoid conflicts and confusion.
4. Fire prevention housekeeping. The standard calls for the control
of accumulations of flammable and combustible waste materials.
It is the intent of this standard to assure that hazardous
accumulations of combustible waste materials are controlled so that a
fast developing fire, rapid spread of toxic smoke, or an explosion will
not occur. This does not necessarily mean that each room has to be swept
each day. Employers and employees should be aware of the hazardous
properties of materials in their workplaces, and the degree of hazard
each poses. Certainly oil soaked rags have to be treated differently
than general paper trash in office areas. However, large accumulations
of waste paper or corrugated boxes, etc., can pose a significant fire
hazard. Accumulations of materials which can cause large fires or
generate dense smoke that are easily ignited or may start from
spontaneous combustion, are the types of materials with which this
standard is concerned. Such combustible materials may be easily ignited
by matches, welder's sparks, cigarettes and similar low level energy
5. Maintenance of equipment under the fire prevention plan. Certain
equipment is often installed in workplaces to control heat sources or to
detect fuel leaks. An example is a temperature limit switch often found
on deep-fat food fryers found in restaurants. There may be similar
switches for high temperature dip tanks, or flame failure and flashback
arrester devices on furnaces and similar heat producing equipment. If
these devices are not properly maintained or if
they become inoperative, a definite fire hazard exists. Again employees
and supervisors should be aware of the specific type of control devices
on equipment involved with combustible materials in the workplace and
should make sure, through periodic inspection or testing, that these
controls are operable. Manufacturers' recommendations should be followed
to assure proper maintenance procedures.
