This article describes safety hazards and safety inspection points for vehicle doors, automatic garage door operators, and also garage passage doors or man-doors giving access between a garage and the building interior.
Page top photo: a typical spring-operated torsion-type garage-door operator mechanism during re-construction of a New York garage. A center spring is wound as the door moves downward.
The spring tension provides a lift-assist for either a manually-operated garage door or for an automatic garage door operator (in our photo the automatic operator is not yet installed).
An improperly-installed or adjusted or obsolete automatic garage door operator is unsafe because it can injure or even kill a child, while access doors between a garage and the building that it serves have their own separate set of safety requirements including fire-resistance, automatic-closing mechanisms, measures to prevent vehicle exhaust or fumes from entering the building, and proper walking surfaces to avoid fall-hazards.

Garage Door Safety Hazards
Our photo above shows an automatic garage door operator and the door itself, in a view not normally available: from above, during reconstruction of a New York garage.
You can see the center spring, torsion bar, and the tracks through which wheels on the garage door segments run as the door moves up or down.

Following our list and discussion of safety hazards at manual and automatic garage vehicle doors or overhead doors, we include a list of hazards at garage passage doors between garage and building.
Garage Vehicle Door Hazards Inspection List
Obsolete garage door operator:
Automatic garage door operator that is an obsolete model that lacks an automatic reversing safety mechanism (In the U.S., older than 1982)
Mis-Adjusted:
Automatic garage door operator whose safety mechanism is not properly adjusted to reverse if it detects an obstruction: misaligned sensor lights or improperly-adjusted obstruction sensor.
Object impact detection system:
The garage door should reverse on striking any object within 1 1/2" of the floor surface or higher. Required on garage door operators made after 1981.
External entrapment protection system:
The garage door should reverse if it detects any object beneath the door path even without striking the object (typically by optical sensors that must be aligned properly). Required on garage door operators made after 1 January 1993.
Optical sensors are usually mounted 4-6" above the garage floor.
Child-access to door controls:
Automatic garage door operator control switch mounted too low - accessible to small children (attractive nuisance)
Also keep remote garage door operator controls out of the reach of children.
Weak, loose operator motor mounts: Garage door or door operator motor or parts not securely mounted to the building structure: falling risk
Automatic garage door operator spring(s) improperly-adjusted,
door out of balance: door should remain in position if stopped during movement
Automatic garage door operator improperly-adjusted
if the door re-opens on its own after closing fully:
homeowner thinks s/he has closed it and drives away, leaving the building open to pests or forming a building security risk
Automatic garage door wheels / track out of alignment,
can cause the door to jam, operator to fail, door to fall entirely out of its tracks, etc.
Overhead garage door tracks not securely-mounted
to the structure: entire door assembly can fall when in the open position.
All door hardware: check for loose parts, bolts, fasteners at handles, step plates, hinges, top fixtures, locks, track brackets. Don't over-tighten as you may strip threads.
Missing emergency release pull cord.
Pulling this cord disengages the trolley, allowing manual lifting of a closed door.
The primary pull cord function is to escape from the garage without assistance from the garage door operator during a power failure or other malfunction.
Pulling the cord also permits verification that the spring(s) and other components are properly adjusted and working smoothly.
This verification is important after repairs or adjustments and should be performed routinely, probably annually.
Overhead garage door left disconnected
from its operator mechanism: heavy garage door may fall during manual effort to open or close it
Sliding or gate-type automatic garage door that lacks obstruction sensors
Additional garage door hazards for which automatic protection mechanisms either are not provided or can not be provided at low cost.
These are in addition to crushing injuries and fractures that occur to children and ascribed to absence or malfunction of the garage door safety hazards listed just above
Garage door lubrication failures
can cause door cables or springs or the operator chain to break, also resulting in property damage or injury.
Typical overhead garage door maintenance, inspection & lubrication are required to maintain a safe garage door opening and closing system:
Door tracks: keep clean of grease and debris;
Door rollers: lightly-oil hinge points. steel roller stems, inner race assembly, locking device moving parts, torsion spring torsion tube, spring coil surfaces, using 30W or other minimum weight oil; wipe off excess;
See the garage door installation and operation manuals given below on this page for more details about garage door operator lubrication requirements.
Amputation or laceration hazards:
fingers, hands, or other body parts may be cut or even amputated if a person's hand or un-protected foot is inserted into dangerous locations such as in the wheel track of the garage door or into the garage door lift cable assembly.
Watch out: Photo above: the garage door lift cable, pulley surfaces, and wheels and track are all exposed in a normal overhead door installation. Keep fingers, hands, toes, clothing away from these opening!
Impact or other injuries:
from pieces of broken garage door springs. Springs are more-likely to break when old (metal fatigue), rusted, or improperly-adjusted (over-stretched horizontal springs or over-wound torsion-bar springs).
Horizontal garage door lift assist springs
connected between the lift cables at each side of the door and the inner-most end of the garage door track can break suddenly, usually at the half-round connectors found at either end of the spring, allowing the garage door to fall suddenly.
We have inspected homes that sported a hole smashed in the garage wall opposite the garage door track, caused when the door spring broke and flew through the air.
Torsion bar
garage door springs
that wrap around a torsion-bar type garage door lift assist spring can break suddenly. Lubrication and inspection are key to avoiding this damage.
Garage door spring hazards:
Watch out: do not try to remove, install, repair or adjust springs or anything to which the garage door parts are fastened such as wood blocks, steel brackets, cables, etc.
Repairs must be done by a trained garage door technician. If you are not trained to do so, attempting to remove a cable or adjust or remove a spring can cause serious injury.
These parts are under tremendous spring tension and can snap, break apart, and cause bodily injury if you attempt to loosen, move, or adjust them.
Missing garage door safety labels:
factory-supplied garage door safety labels are provided for as many as seven different garage door hazards, depending on where you live.
These labels have required locations so that important safety warnings can be observed by the homeowner and others. Examples of garage door safety labels include
Operator bracket warning label
Torsion spring tag warning label (one per spring)
Cleaning instructions label
Residential safety warning label
Door bottom section safety warning labels
Door instruction manual & manual envelope
OPINION: Garage door operators that do not comply with voluntary ANSI/UL Standard 325-1982 are unsafe.
Unsafe Torsion-bar Type Garage Door Operator
Depending on its construction materials, a double-wide overhead garage door like the one in this photo can be particularly heavy.
Thanks to an InspectApedia reader we have these photographs of a damaged torsion-bar type garage door operator that is unsafe.
Should the gouged, damaged torsion bar break (or should the spring itself break) the garage door can come crashing down, injuring anyone who is below the door, or causing property damage.
Watch out: this is dangerous: the end of the track bolt above the rotating garage door operator pipe or bar has so gouged into the pipe that there is risk of its eventual breakage: releasing the torsion spring and sending the door crashing down.
Horizontal or Moving Gate Garage Vehicle Door Operators
Above and below, installed in a Minneapolis MN home, we see a long garage door that moves horizontally to open or close two sides of a garage to permit vehicles to use the garage from an otherwise difficult alley-access.
Gate type door operators also need a safety mechanism to detect an obstruction anywhere in the sliding door's passage, so that injury or property damage can be prevented.
Garage Passage Door of "Man Door" Safety
In-Garage Stairs to Basement = explosion waiting to happen
Our photo illustrates an unsafe entry stair passing from a residential garage into the home's basement:
a stairway originating on the garage floor passes down into the building's basement.
Watch out: As heating equipment is most often found in the home's basement, imagine the explosion that may occur (one did, despite our emphatic warnings, in Fishkill NY) if a vehicle leaks gasoline and gasoline fumes into the garage.
Gasoline fumes, heavier than air, fall down the stairwell, into the basement (or crawl space) where, at the next spark or flame, there is risk of an explosion.
A "fire door" in the stairwell bottom is not enough security for this installation. In fact, as you can see, the (not fire-rated) door has been left ajar.
Garage Passage Door Hazards & Safety Inspection Points
Garage passage door not fire rated
or exterior type - building and fire codes require a fire-rated door between the garage and the building interior (and other fire-resistant measures as well, such as fire-rated walls between garage and building interior)
Garage passage door not tight-fitting
and weather stripped - risking leaks of fatal carbon monoxide (CO) if a vehicle is left running in the garage
No garage passage door automatic self-closing mechanism
- risking leaks of fatal carbon monoxide (CO) if a vehicle is left running in the garage and risking fire spread should a fire occur in the garage
No step up from garage floor to building interior
- risking leaks of fatal carbon monoxide (CO) if a vehicle is left running in the garage
Garage floor includes stairs down
into basement utility area (heating equipment) or occupied space (CO hazards)
Garage passage door opens into bedroom
- risking leaks of fatal carbon monoxide (CO)

Excerpt: The U.S. Consumer Product Safety Commission (CPSC) staff participates in the Underwriters Laboratories, Inc. (UL) Standards Technical Panel (STP) for ANSI/UL 325, Safety for Door, Drapery, Gate, Louver, and Window Operators and Systems. CPSC staff participation allows us to provide input into changes to the voluntary standard and the associated CPSC mandatory safety rule (16 CFR part 1211), and to provide the Commission with the earliest possible notification of proposed changes to the rule.
The Consumer Product Safety Improvement Act of 1990 (Improvement Act) mandated that automatic residential garage door operators (GDOs) manufactured on or after January 1, 1991 conform to the entrapment protection requirements of the 1988 version of UL 325.
On June 19, 1991, the Commission issued the garage door operator standard (16 CFR Part 1211).

Excerpts: SUMMARY: The Consumer Product Safety Commission (Commission, or CPSC) is amending its regulation, Safety Standard for Automatic Residential Garage Door Operators, to reflect changes made by Underwriters Laboratories, Inc. (UL), in the entrapment protection provisions in UL’s standard UL 325, Standard for Safety: Door, Drapery, Gate, Louver, and Window Operators and Systems, Seventh Edition.
... Homeowners with automatic garage door
openers that do not automatically reverse
should repair or replace them with new
reversing openers. This prevents young
children from being trapped and killed
under closing garage doors.
According to reports received by the U.S.
Consumer Product Safety Commission
(CPSC), about 73 children between the
ages of 2 and 14 have been trapped and
killed under automatic garage doors since
March 1982.
This is about three such
deaths per year on average. Other
children have suffered brain damage or
serious injuries when the closing door hit
them, and failed to stop and reverse its
direction.
The Consumer Product Safety
Commission (‘‘Commission’’ or ‘‘CPSC’’)
is issuing a final rule amending the
regulations for the Safety Standard for
Automatic Residential Garage Door
Operators to reflect changes made by
Underwriters Laboratories, Inc. (‘‘UL’’),
in the entrapment protection provisions
in UL’s standard UL 325, Sixth Edition,
‘‘Standard for Safety for Door, Drapery,
Gate, Louver, and Window Operators
and Systems.’’
DATES: The rule is effective on May 9,
2016
