II USER INSTRUCTIONS FOR THE SAFERAIL-FALL ARREST SYSTEM
The SafeRail-fall arrest system and the SafeRail Carriage-safety carriage ensure safe ascent and descent
through its built-in fall arrest feature. The system is designed to be used on vertical structures.
Using the system for any other purposes than those specified by the manufacturer is forbidden.
If the product is sold outside of Finland, the reseller must deliver the installation and user instructions of the
SafeRail-fall arrest system in the language of the country in question.
1. BEFORE EACH USE
The user must review the user instructions before using the SafeRail-fall arrest system as well as be familiar
with the use of fall protection equipment (SafeRail Carriage-safety carriage, Vertical SafeRail-safety rail, and
the safety harness).
Before each use, the user must ensure that a commissioning inspection has been carried out for the
SafeRail-fall arrest system and perform the appropriate checks according to sections 1.1–1.4.
1.1 INSPECTING SAFERAIL LADDERS AND/OR VERTICAL SAFERAIL-SAFETY RAILS
AND THE SAFERAIL CARRIAGE-SAFETY CARRIAGE BEFORE EACH USE
•The structures of the SafeRail ladder and/or the Vertical SafeRail-safety rail are undamaged. In
order to check that the SafeRail ladder and/or the Vertical SafeRail-safety rail have been installed
correctly, the user must also review the installation instructions.
•The structures to which the SafeRail ladder and/or the Vertical SafeRail-safety rail have been
attached are undamaged.
•The screws, bolts, and nuts of the fasteners and the extension pieces used to secure the SafeRail
ladder and/or the Vertical SafeRail-safety rail are safely and securely attached.
•The spring of the SafeRail Carriage-safety carriage is properly in place and functional. The condition
of the spring must be verified by coupling the carriage with and moving the carriage along the
Vertical SafeRail-safety rail and letting go. After falling, the SafeRail Carriage-safety carriage will lock
automatically on to the locking notches if the spring is working as expected. The Vertical SafeRail-
safety rail is equipped with locking notches every 150 mm.
•The SafeRail Carriage-safety carriage has not been deformed.
•The markings on the SafeRail ladder and/or the Vertical SafeRail-safety rail as well as on the
SafeRail Carriage-safety carriage are clearly legible.
•Please note that incorrect installation of the SafeRail ladder and/or the Vertical SafeRail-safety rail
and/or incorrect assembly of components may lead to the following hazardous situations, for
example:
oIf the recommended fixing distances have not been followed, the SafeRail ladder and/or the
Vertical SafeRail-safety rail may become detached causing the user to fall down with the
detached components or be seriously injured as detached components fall on the user, or
seriously injuring or subjecting to mortal danger other people further below or at ground
level. In the worst case, the SafeRail ladder and/or the Vertical SafeRail-safety rail becoming
detached may also subject the user to mortal danger.
oIf, contrary to the prohibition in the installation instructions, the SafeRail ladder and/or the
Vertical SafeRail-safety rail have been installed at a negative angle of climb, the SafeRail

Page 13
Carriage-safety carriage will not lock on to the locking notches on the Vertical SafeRail-
safety rail and thus won't stop the user from falling, subjecting them to mortal danger.
oIf a Carriage Guide-carriage guide MM 301 has not been installed at both the top and bottom
end of the SafeRail ladder and/or the Vertical SafeRail-safety rail, it is possible for the user
to accidentally couple the SafeRail Carriage-safety carriage with the safety rail the wrong
way round, in which case the carriage will not lock on to the locking notches on the Vertical
SafeRail-safety rail and thus will not stop the fall. This will subject the user to mortal danger.
oIf the Carriage Guide-carriage guide MM 301 has been installed incorrectly such that the
locking screw is placed on the right side of the safety rail instead of the left, it is possible for
the user to accidentally couple the SafeRail Carriage-safety carriage with the safety rail the
wrong way round, in which case the carriage will not lock on to the locking notches on the
Vertical SafeRail-safety rail and thus will not stop the fall. This will subject the user to mortal
danger.
oIf Carriage Stopper-carriage barriers have not been installed to both the top and bottom
ends of the SafeRail ladder and/or the Vertical SafeRail-safety rail, the SafeRail Carriage-
safety carriage may come off the safety rail accidentally, thus subjecting the user to mortal
danger. In this case, mortal danger is particularly present at the top end of the safety rail,
where the risk of falling from a height is significant.
oIf an unlocking Carriage Stopper-carriage barrier MM 312 has been installed incorrectly at
the bottom of the SafeRail ladder and/or the Vertical SafeRail-safety rail instead of the top
end, there is a risk that the SafeRail Carriage-safety carriage may come off the safety rail
accidentally, in which case the user may fall. At the bottom end of the safety rail, the fall is
unlikely to be at height, if the installation is compliant with the ground clearance specification
of the installation instructions for the SafeRail ladder and/or the Vertical SafeRail-safety rail,
which allows for a maximum ground clearance of 1000 mm.
oIf an unlocking Carriage Stopper-carriage barrier MM 311 has been installed incorrectly at
the top end of the SafeRail ladder and/or the Vertical SafeRail-safety rail instead of the
bottom, there is a risk that the SafeRail Carriage-safety carriage may come off the safety rail
accidentally, thus subjecting the user to mortal danger. In this case there is a risk of falling
from significant height.
oIf SafeRail ladders and/or Vertical SafeRail-safety rails have been connected to each other
using some other components than the SafeRail Joint-extension pieces or the SafeRail
Joint- extension pieces have not been appropriately tensioned, there is a danger that the
joints fail and the SafeRail Carriage-safety carriage comes off the safety rail. This may
subject the user to mortal danger.
1.2 INSPECTING THE SAFETY HARNESS AND THE SUPPORT ROPE BEFORE EACH
USE
•The harness used must be a full-body harness conformant with the EN 361 standard, which is in the
condition required by the relevant regulations. The front of the harness must have a D-ring, or
another approved attachment point for attachment to the SafeRail Carriage-safety carriage.
•The attachment point on the safety harness is attached directly to the carabiner on the SafeRail
Carriage-safety carriage, which conforms to the requirements of the EN 362 standard. Check that
the locking screw-gate on the carabiner closes securely.
•The safety harness must be adjusted to fit the user sufficiently tightly.

Page 14
•In addition to the safety harness, the user must have two undamaged support ropes for climbing.
(The support ropes provide additional security while resting and working.)
1.3 CHECKING THE MAXIMUM AND MINIMUM WEIGHT OF THE USER, THE NUMBER
OF USERS, THE DISTANCE BETWEEN USERS, AND THE MINIMUM OPERATING
TEMPERATURE BEFORE EACH USE
•The maximum weight of a user including gear (tools and other equipment) is 160 KG.
•The minimum weight of a user excluding gear (tools and other equipment) is 60 KG.
•The minimum operating temperature is -25 °C.
•The number of concurrent users per each SafeRail Carriage-safety carriage is MAX. 1 PERSON.
•The distance between users during climbing must be > 6 M.
•Multiple users may use a SafeRail ladder element and/or a Vertical SafeRail-safety rail element at
the same time, but then it must be ensured that the number of users on each section between
fasteners is MAX. 1 PERSON.
1.4 ENSURING OTHER KEY FACTORS OF WORK SAFETY BEFORE EACH USE
•The working ability and state of health of the user must be verified to be suitable for using the
SafeRail-fall arrest system.
•Working alone is not recommended with the SafeRail-fall arrest system.
•Make sure that you are equipped with workwear that is suitable for climbing, working, and the
prevailing conditions, as well as a helmet and safety shoes.
•Before using the system, prepare for potential accidents and plan how to act in a hazardous
situation. The relevant rescue procedure must be immediately available and realizable in the event
of an accident during use.
•Please note that the SafeRail Carriage-safety carriage cannot be used to prevent falling. It is instead
designed to arrest a user’s fall. When falling down, the SafeRail Carriage will automatically lock on to
the locking notches placed at 150 mm intervals on the Vertical SafeRail-safety rail. If fall prevention
is required, personal protective equipment designed specifically for the purpose must be used.
•You may not adjust the length of the attachment element on the SafeRail Carriage-safety carriage
(the carabiner) by, for example, adding or removing connecting equipment.
•Before each use, you must check that there is enough space below the working area to prevent
bumping against structures or the ground, for example.
IF ANY DEFICIENCIES/DEFECTS ARE NOTICED DURING THE INSPECTIONS
CARRIED OUT BEFORE USE OR THERE ARE DOUBTS CONCERNING THE
CONDITION OF THE SYSTEM, A WRITTEN NOTIFICATION MUST IMMEDIATELY BE
SUBMITTED TO THE PARTY RESPONSIBLE FOR THE MAINTENANCE OF THE
SYSTEM. BEFORE USING THE SYSTEM, EACH DEFICIENCY/DEFECT NOTICED
DURING INSPECTION MUST BE REMEDIED. THE SAFERAIL-FALL ARREST SYSTEM
CANNOT BE MODIFIED IN ANY WAY AND ITS COMPONENTS CANNOT BE
REPLACED WITH ANY OTHER COMPONENTS THAN THOSE APPROVED BY THE
MANUFACTURER OF THE SYSTEM.

Page 15
2. USER INSTRUCTIONS FOR THE SAFETY HARNESS AND THE SAFERAIL
CARRIAGE-SAFETY CARRIAGE
•Attach the locking carabiner of the SafeRail Carriage-safety carriage to the attachment point (D-ring)
on the front of your safety harness conformant with the EN 361 standard or another approved
attachment point. The attachment points are indicated with the letter “A” on the harness. The safety
harness must have two fixed support ropes. The length of one of the support ropes must be
adjustable with a sliding adjuster.
•If the full-body harness loosens during use, it must be immediately tightened to fit. The full-body
harness may not be used when loose, it must be properly tightened to fit.
•Check that the safety carriage is compatible with the Vertical SafeRail-safety rail.
•Only a single user may be attached to a SafeRail Carriage-safety carriage at any one time. The pin
on the SafeRail Carriage-safety carriage must remain on the left side of the carriage as the carriage
is coupled with the rail, and the Up arrow engraved on the carriage must point up.
•The attachment to and detachment from the safety rail must take place in a safe location, or it must
be done while using separate fall protection equipment.
•When climbing, the distance between the safety harness and the SafeRail Carriage-safety carriage
must be adjusted so that the angle of lean is minimized, thus reducing the strain on the safety
harness to a minimum. However, the user’s knees may not bump into the steps of the ladder while
climbing. Please note that even small changes in the tension of the safety harness have a significant
effect on the optimal functionality of the SafeRail Carriage-safety carriage and the safety harness.
•The fastening must always be secured by a support rope when working or resting. In addition, the
positioning of the anchorage points and the performance of the work must be planned out such that
the potential for a fall and the potential falling height are minimized.
•During climbing, the user must lean back to allow the SafeRail Carriage-safety carriage to move
smoothly along the Vertical SafeRail-safety rail and the climbing to remain effortless. While climbing,
the SafeRail Carriage-safety carriage automatically follows the user.
•In case the user falls, or another similar situation occurs, where the external pulling force that the
safety carriage is subjected to disappears, the carriage will slide down the rail and lock into place by
the locking notches on the Vertical SafeRail-safety rail. The Vertical SafeRail-safety rail is equipped
with locking notches every 150 mm.
•If the SafeRail-fall arrest system has been installed such that the SafeRail Carriage-safety carriage
must be disconnected from the safety rail to allow the user to transfer to the next safety rail, the
transfer must be performed while attached to a secondary anchorage point, e.g. by one of the
support ropes carried by the user.
•More than one user may be supported by a Vertical SafeRail-safety rail, but in this case, it must be
ensured that each section between the fasteners only has a single user at any one time.
•Use of the SafeRail Carriage-safety carriage for any other purposes other than climbing is forbidden.
•Use of the SafeRail Carriage-safety carriage and the fall arrest system while under the influence of
alcohol, drugs, performance decreasing medication, or any other substances that may impede
performance is strictly forbidden.
•Before using the system, it must be ensured that the user's working ability and state of health are
suitable for using the SafeRail Carriage-safety carriage and the fall arrest system. If the user is in a
poor physical condition or suffers from, for example, repeated dizziness, epilepsy, heart disease,
serious lung disease, mental health disorder (including fear of heights), or significant reduction in

Page 16
joint function the user may not be suited for using the SafeRail Carriage-safety carriage and the fall
arrest system. If there are any doubts related to state of health or working ability of the user, it should
be checked by a doctor before using the system.
•Please note that the SafeRail Carriage-safety carriage may not be taken outside in freezing
temperatures while wet.
•Also note that SafeRail Carriage-safety carriages designed for horizontal use can never be used for
vertical climbing.
•If atypical wear is noticed on a SafeRail Carriage-safety carriage, the carriage's claw does not
automatically extend outside the body of the carriage, or the plastic sleeves have worn through, the
carriage must immediately be removed from use and replaced with a new SafeRail Carriage-safety
carriage.
•When a SafeRail Carriage-safety carriage has stopped a falling user, it must be removed from use
and replaced with a new one.

not be replaced with any other parts than those approved by the manufacturer.
3.1 SAFERAIL CARRIAGE-SAFETY CARRIAGE
•The SafeRail Carriage-safety carriage is made from stainless steel and plastic, and it is almost
maintenance-free. The SafeRail Carriage-safety carriage is not susceptible to weather conditions or
corrosion.
•The SafeRail Carriage-safety carriage does not require lubrication or oil. It is advisable to dry off the
SafeRail Carriage-safety carriage after use if it has become wet. While drying, avoid subjecting the
SafeRail Carriage-safety carriage to direct heat. It is also advisable to clean the SafeRail Carriage-
safety carriage as necessary to ensure that it is comfortable to use, and the safety markings remain
clearly legible. Where necessary, cleaning agents suitable for stainless steel may be used to clean
the carriage. When cleaning the carriage, follow the cleaning methods specified above closely.
•The SafeRail Carriage-safety carriage must be stored such that it is protected from weather
conditions and dirt.
•It is forbidden to do any changes, additions or repairs to the SafeRail Carriage-safety carriage.
3.2 SAFERAIL LADDERS AND VERTICAL SAFERAIL-SAFETY RAILS
SafeRail ladders and Vertical SafeRail-safety rails retain their functionality without any special maintenance
or cleaning. Neither do special requirements exist for their storage.
If SafeRail ladders and Vertical SafeRail-safety rails are installed in a location that is highly susceptible to
corrosion (such as above a swimming pool), specific monitoring measurements must be carried out.
