Here are some helpful safety tips. This list is not intended to be a comprehensive list of every safety
precaution. Always consult your manufacturer’s installation or instruction manual for safety information
about your model.
FOR GARAGE DOORS
Replace Old Springs. Your garage door’s springs are arguably the most important and most
dangerous part of your door. Springs wear out. When they break, injury can result. If you have an older
garage door, have your springs inspected by a professional technician and replaced if needed. If your
door has two springs, replace both, even if one is not broken. This will not only prevent any damage
caused by the breaking of the second spring, but also keep your door working efficiently.
Check Your Cables. Visually inspect the cables that attach the spring system to the bottom brackets
on both sides of the door. If these cables are frayed or worn, they are in danger of breaking, which can
cause injury. Due to the dangers associated with high spring tension, these cables should be replaced
only by a trained technician.
Squeaky Springs? Springs can squeak and be noisy. This is caused by normal use and does not
necessarily indicate a problem. Before calling a professional service technician, use a spray-on lubricant
(recommended especially for garage doors). If the noise persists, call a professional garage door installer
A Do-It-Yourselfer, Eh? Installing a garage door can be very dangerous and is not recommended for
a novice. DASMA recommends that trained door systems technicians install garage doors. If you attempt
the installation by yourself, be sure to follow the manufacturer’s installation instructions carefully.
Safety Cables. If your garage door has extension springs, you need a safety cable that runs through
the spring and secures to the wall or ceiling at each end. When your garage door is down, extension
springs are under high tension. If the spring breaks, it may cause injury. A safety cable can keep that
broken spring contained. If you have extension springs but do not have a safety cable, call your local
dealer for a safety inspection.
Struggling Door? If your door does not go up and down smoothly, you may have an unsafe condition.
Even older door systems should operate smoothly. If the awkward operation continues when the door is
manually operated, you may have a spring system that is out of balance. This can cause premature wear
and tear on other important door components. Spring systems are dangerous and should be repaired
only by trained professionals.
Watch Your Fingers! Every year, many unsuspecting homeowners injure their fingers by placing them
between the door sections to pull down on the door. According to DASMA Standard 116, if your door
lacks pinch-resistant joints, you should have lift handles or suitable gripping points on the inside and
outside of the door. Even if your door has an opener, the door must occasionally be operated manually.
Never place your fingers between the door sections. If you manually open or close the door, use the
handles or the safe gripping points!
Tamper Resistant Brackets. Since the bottom brackets on a garage door are connected to the
door’s springs, these brackets are under extreme tension. They should be adjusted or loosened only
by a trained door systems technician. Many manufacturers now include tamper resistant hardware that
prevents loosening of the brackets by a novice.
Use the Old Track? When buying a replacement garage door, some homeowners are tempted to
save a few dollars by putting the new door on the old track. However, your old track may not fit with your
new door, depending on the thickness of your sections, the weight of the door, the headroom required,
the location of the garage door opener, and other considerations. The track and sections work together
as a system. For maximum performance and long life, you should use the track that is designed for your
Regular Service. Your garage door is probably the largest moving part in your home and is typically
used every day. Over time, parts can wear out and break, creating potential safety problems. Although
you should provide monthly safety checks and maintenance to your garage door system, an annual visit
from a trained door systems technician can keep your door operating safely and smoothly for a long time.
Man the Manual. Keep the owner’s manuals for your door and opener hanging near the door for easy
reference. Every model of door and opener has specific safety instructions unique to that model. Where is
