OWNER’S/USER’S RESPONSIBILITIES

1)  The manufacturer shall provide to the initial 

purchaser and make the following information 

readily available to the owners/users and their 

agents, all necessary information regarding Safety 

Information, Operation, Installation and Safety 

Precautions, Recommended Initial and Periodic 

Inspections Procedures, Planned Maintenance 

Schedule, Product Specifications, Troubleshooting 

Guide, Parts Break Down, Warranty Information, and 

Manufacturers Contact Information, as well as tables 

to identify the grade(slope) for all variations of length 

or configuration of the dock leveling device and 

information identifying the maximum uncontrolled 

drop encountered when sudden removal of support 

while in the working range of the equipment.

2)  When selecting loading dock safety equipment, it is 

important to consider not only present requirements 

but also future plans and any possible adverse 

conditions, environmental factors or usage. The 

owners/users shall provide application information 

to the manufacturer to receive recommendations on 

appropriate equipment specifications and capacity.

3)  The Owner/User must see all nameplates, placards, 

decals, instructions and posted warnings are in 

place and legible and shall not be obscured from 

the view of the operator or maintenance personnel 

for whom such warnings are intended for. Contact 

manufacturer for any replacements.

4)  Dock leveling devices may become hazardous if the 

manufacturer’s instructions regarding modifications 

or adjustments are not followed. Modifications 

or alterations of dock leveling devices shall only 

be made with prior written approval from the 

original manufacturer. These changes shall be 

in conformance with all applicable provisions of 

the MH30.1 standard and shall also satisfy all 

safety recommendations of the original equipment 

manufacturer of the particular application.

5)  The owner/user should recognize the inherent 

dangers of the interface between the loading dock 

and the transport vehicle. The owner/ user should, 

therefore, train and instruct all operators in the safe 

operation and use of the loading dock equipment in 

accordance with manufacturer’s recommendations 

and industry standards. Effective operator training 

should also focus on the owner’s/user’s company 

policies, operating conditions and the manufacturer’s 

specific instructions provided with the dock leveling 

device. Maintaining, updating and retraining all 

operators on safe working habits and operation of 

the equipment, regardless of previous experience, 

should be done on a regular basis and should include 

an understanding and familiarity with all functions of 

the equipment.  Owners/users shall actively maintain, 

update and retrain all operators on safe working habits 

and operations of the equipment.

6)  An operator training program should consist of, but not 

necessarily be limited to, the following:
a)  Select the operator carefully. Consider the physical 

qualifications, job attitude and aptitude

b)  Assure that the operator reads and fully 

understands the complete manufacturer’s owners/

users manual.

c)  Emphasize the impact of proper operation upon the 

operator, other personnel, material being handled, 

and equipment. Cite all rules and why they are 

formulated.

d)  Describe the basic fundamentals of the dock 

leveling device and components design as related 

to safety, e.g., mechanical limitation, stability, 

functionality, ect.

e)  Introduce the equipment. Show the control 

locations and demonstrate its functions. Explain 

how they work when used properly and maintained 

as well as  problems when they are used 

improperly.

f)  Assure that the operator understands the 

capacity rating, nameplate data, placards and all 

precautionary information appearing on the dock 

leveling device.

g)  Supervise operator practice of equipment.

h)  Develop and administer written and practical 

performance tests. Evaluate progress during and at 

completion of the course.

i)  Administer periodic refresher courses. These may 

be condensed versions of the primary course and 

include on-the-job operator evaluation.

7)  Loading dock safety equipment should never be 

used outside of its vertical working range, or outside 

the manufacturer’s rated capacity.  It shall also be 

compatible with the loading equipment and other 

conditions related to dock activity. Please consult the 

manufacturer if you have any questions as to the use, 

vertical working range or capacity of the equipment. 

Only properly trained and authorized personnel should 

operate the equipment.

8)  It is recommended that when the transportation vehicle 

is positioned as close as practical to the dock leveling 

device and in contact with both bumpers, there shall be 

a minimum of 4.00 inches (100mm) overlap between 

the front edge of the lip and the edge of the floor or sill 

of the transport vehicle at all times during the loading 

and unloading process.
