SAFETY WARNINGS
LOCKOUT/TAGOUT PROCEDURES
The Occupational Safety and Health Administration requires that, in addition to posting safety warnings and
barricading the work area, the power supply has been locked in the OFF position or disconnected. It is mandatory
that an approved lockout device is utilized. An example of a lockout device is illustrated. The proper lockout
procedure requires that the person responsible for the repairs is the only person who has the ability to remove the
lockout device.
In addition to the lockout device, it is also a requirement to tag the power control in a manner that will clearly note
that repairs are under way and state who is responsible for the lockout condition. Tagout devices have to be
constructed and printed so that exposure to weather conditions or wet and damp locations will not cause the tag to
deteriorate or become unreadable.
Rite-Hite Corporation does not recommend any particular lockout device, but recommends the utilization of an
OSHA approved device (refer to OSHA regulation 1910.147). Rite-Hite Corporation also recommends the review and
implementation of an entire safety program for the Control of Hazardous Energy (Lockout/Tagout). These regulations
are available through OSHA publication 3120.
When working with electrical or electronic
controls, make sure that the power source has
been locked out and tagged according to OSHA
regulations and approved local electrical codes.
FIGURE 1 - LOCKOUT/TAGOUT
This is the highest level statement. Failure to
follow the listed instructions will most likely
result in severe injury or death.
IMPORTANT is used to draw attention
to a procedure that needs to be followed to
prevent machine or property damage.
This is a statement of serious hazard. Failure to
follow the listed instructions could place the
individual at risk of serious injury or death.
The statements used with this level of
warning deal with a safe operating
procedure. If the procedure is ignored, the
possibility of personal injury may exist.

OWNER RESPONSIBILITY
1. The owner should recognize the inherent danger of
the interface between dock and transport vehicle.
The owner should, therefore, train and instruct
operators in the safe use of dock equipment in
accordance with the information provided below.
The manufacturer shall publish, provide to the initial
purchaser, and make the following information
readily available to owners:
•Installation instructions
•Recommended initial and periodic inspections
procedures
•Maintenance procedures
•Operating instructions
•Descriptions or specifications for replaceable or
repairable parts
•Tables identifying the grade (slope) for all
variations of length or configuration of the dock
equipment, and
•Information identifying the maximum
uncontrolled drop encountered upon sudden
removal of support while within the working
range of the equipment.
It shall be the responsibility of the owner to verify
that the material listed in this section has been
received and that it is made available for the
instruction and training of presonnel entrusted with
the use or maintenance of the dock equipment.
2. When a transport vehicle is parked at a loading
dock, it is important that the vehicle is relatively
perpendicular to the dock face and in close contact
with at least one of the dock bumpers.
3. Nameplates, cautions, instructions, and posted
warnings shall not be obscured from the view of
operating or maintenance personnel for whom such
warnings are intended.
4. Manufacturer’s recommended periodic maintenance
and inspection procedures in effect at date of
shipment shall be followed, and written records of
the performance of these procedures should be kept.
5. As with any piece of machinery, dock equipment
requires routine maintenance, lubrication, and
adjustments. Your local Rite-Hite representative
offers owners the option of a Planned Maintenance
Program (P.M.P.). As part of this service, your local
Rite-Hite representative will do all routine
maintenance, lubrication, and adjustments.
6. Dock equipment that is structurally damaged shall
be removed from service, inspected by a
manufacturer’s authorized representative, and
repaired as needed before being placed back in
service.
7. The manufacturer shall make available
replacement nameplates, caution/instruction labels,

must have been properly installed, maintained and
operated within its rated capacities and/or specific
design parameters, and not otherwise abused.
10. It is recommended that trailers equipped with air
ride suspensions should remove the air from the
suspension to minimize trailer bed drop, prior to
loading or unloading.
11. When industrial trucks are driven on and off
transport vehicles during the loading and unloading
operation, the brakes on the transport vehicle shall
be applied and wheel chocks or a positive
restraining device shall be engaged.
12. In selecting dock equipment, it is important to
consider not only present requirements but also
future plans or adverse environments.

Pub. No. 1307 - July 2013 5
The MWL-1300 vehicle restraint is a truck and trailer
locking system used to help secure trucks and trailers to
the face of a loading dock. The barrier is deployed in
front of the tire after the trailer has been positioned
against the dock bumpers.
This prevents forward movement of the truck/trailer that
may create an unsafe void between the face of the dock
and the rear end of the truck/trailer as the forklift travels
from the loading dock onto the trailer; and creates an
obstruction noticeable (via outside lights) to the truck
driver, should the driver accidentally try to pull the truck/
trailer away while it is being serviced.
The normal mode of the restraint is the barrier assembly
is stored at the near end (closest to the dock). Inside
lights should be flashing red and outside lights should be
flashing green.
The proper activation of the wheel restraint is monitored
by:
•VISUAL CONTROL
– one set of flashing green and red lights located
inside the building for the dock personnel, and
one set located outside the building for the truck
driver. See Figure 2.
• AUDIO CONTROL
– a horn sounds inside and outside the building,
warning dock personnel when the locking
mechanism is not properly activated. In this case,
the truck or trailer must be secured by other
means (wheel chocks etc.) prior to servicing the
trailer. See Figure 3.

been locked out and tagged according to OSHA
regulations and approved local electrical codes.
Post safety warnings and barricade work area,
at dock level and at ground level, to prevent
unauthorized use of the dock position.
A safe work place requires all lights and the
horn to be working properly. DO NOT use
MWL-1300 vehicle restraint if parts are broken
or missing.
Maintenance may be required more frequently
at loading docks exposed to harsh
environments (extreme climates, corrosive
chemicals, frequency of usage exceeding 8
trucks per day, etc.). Consult RITE-HITE if these
conditions exist for accelerated maintenance
requirements.
