Control of contractors
As part of any contractor control on site you must identify safe systems of work on or about the
rides and attractions as part of your overall contractor / sub-contractor and routine staff scheme.
Lock out protocols will often fall into the permit to work system alongside, excavations, working at
height and hot works for example.
When selecting your contractor;

Example Sections of contractors scheme
Induction training
Contractor’s employees will be given induction training specific to the location such that they are alerted
to site requirements and emergency procedures.
The Contractor is responsible for providing his employees with appropriate information on the health
and safety plan and any potential hazards and precautionary measures
part of any contractor control on site you must identify safe systems of work on or about the rides and
attractions as part of your overall contractor / sub-contractor and routine staff scheme.
Confined spaces
The Contractor must provide the park representative in charge of the contract with an appropriate
method Statement before work takes place in the Confined Space.
Method Statements must take account of all statutory regulations on Confined Spaces.
Appropriate emergency procedures must be in place for all work in confined spaces.

Example Sections of contractors scheme
First aid
A suitable assessment should be carried out by the Contractor to determine an appropriate provision for
First Aid.
Where a site is remote from emergency medical services, contractors may need to make special
arrangements to ensure appropriate transport is available. On a shared or multi-occupied site,
employers can arrange for one employer to take responsibility for providing first-aid cover for all the
workers. All employers should agree the arrangements and employees should be kept informed.
Subject to negotiation, joint arrangements may be made between the Contractor and the park
representative in charge of the contract to provide common cover, however the adequate provision of
first-aid arrangements should not be assumed.

Example Sections of contractors scheme
Working at height
Suitable provision must be made to protect persons who work in situations where they are liable to fall.
Such provisions may include:- guard rails; toe-boards; barriers; working platforms; personal suspension
equipment; fall arrest equipment; safety nets and inflatable cushion's.
Any precautions taken to prevent falls from height should be a result of a suitable and sufficient risk
assessment and should be clearly defined in a method statement.
The installation or erection of scaffolds and personal suspension equipment must be under the
supervision of a competent person.
The Contractor must comply with statutory regulations for Working at Height.

What is the purpose of a Lockout Procedure?
Key principles
•
A procedure which will protect employees and contractors of the park from
inadvertent operation of mechanical equipment, and energizing of electrical
circuits, while performing work on, or in the immediate vicinity of, motordriven, electrical, or pressurized equipment.
•
Lockouts will primarily be used on or about the Rides and Attractions at the
park to isolate ride systems in whole or in part.
•
Providing a safe system of work and to meet your legal requirements. In
UK - as per H.A.S.A.W.A. Section 2 and P.U.W.E.R. regulation 19. - Check
EU or your own legal framework.
•
Lock out is a planned safety procedure which involves turning off the
energy supply of equipment and machinery whilst maintenance and repairs
are being carried out.
•
This procedure protects workers from danger and from machinery (mainly
ride systems) being set in motion.

What is a Lockout Procedure?
In general terms
•
All park employees and contractors shall not work on or in ride
enclosure areas, equipment, vessels, etc., which are not in a
"zero" energy state.
•
Many of the rides and attractions at our park expose
employees and contractors to a variety of energy sources that
can be hazardous.
•
These sources include, but are not limited to, electrical circuits,
hydraulic systems, pneumatic systems, and the forces of
gravity.
•
An unexpected or sudden release of any of these energy
sources can expose employees to moving equipment, electrical
shock, burns, or hazardous materials.
•
For proper employee protection, exposure to all power sources
and/or hazardous materials must be positively eliminated.

Responsibility to Lock out
While it is the responsibility of the park to provide this policy, training and equipment required, the
ultimate responsibility to recognize and secure all hazardous energy sources lies within each employee
who might be required to apply or abide with the provisions of the policy.
All park employees have the responsibility to immediately report all unsafe conditions to their
supervisors or line managers.
Locks and keys will be issued by the Park Operations Department. Each Park Department will maintain
a master list of lock and key numbers for every lock issued. This list will be published, as well as
revised, for Operations, engineering and facilities maintenance.
Example:
These locks will be identified by departmental colour coding as follows:
•
•
•
•
Ride and Attractions Maintenance Team.
Ride & Attractions Operations Team.

Contractors
Blue
Red
Green
Yellow
The Rides and Attractions Maintenance Department shall identify and label each energy isolating
device for all Rides and Attractions that could pose a hazard if unexpectedly energized or started.

The Policy
Overview
Any park employee and/or contractors who are required to work in or around rides or any energized
equipment must carry and use a lockout device and department identification padlock tag when
performing any maintenance, inspection, and/or cleaning and adjusting of equipment.

Common definitions
Zero energy state
The state of equipment in which every power source that can produce movement of a part of the
equipment, or the release of energy, has been rendered inactive.
Affected employee
An employee whose job requires him/her to operate or use a Ride or Attraction on which service or
maintenance is being performed under lockout or whose job requires him/her to work in an area where
such work is being performed.
Authorized employee
An employee who locks out Rides and Attractions in order to perform servicing, inspection or
maintenance on the equipment.
Energy isolating device
A mechanical device that physically prevents that transmission or release of energy, including but
not limited to the following: a manually-operated electrical circuit breaker; a disconnect switch;
and any similar device used to block or isolate energy. Push buttons, selector switches, and other
control devices are not energy isolating devices.

Lockout hasp, padlock and tag.
Energized
Connected to an energy source or containing residual or stored energy.
Lock-out point
Location of an energy isolating device.
Restricted ride enclosure area
A ride area within a rides operational zone where a person could come into contact with an operational
ride system or a part of a system. Such as inside a roller coaster track area.
Identification tag
ID Tags identifying who (by name or department) has installed the lock-out device and padlock.
Get insights. Get educated. Get inspired.
Lock out procedure
The procedure must be followed when working on any energized equipment or entering a
restricted ride enclosure area:
•
•
•
Locate the Lockout point.
Engage the lock-out device and padlock including identification tag.
After the Lockout has been engaged but before activity commences, verify that all hazardous
energy has been isolated and or released. This includes any other part of the ride system that
could affect your safety if energised
As people complete their work on the equipment, they must remove their
lock and tag and disengage the lock-out device if other locks are not present.
Important Note:
The Lockout devices can accommodate several locks.
•
•
NEVER depend on another person(s)/departments lock,
they could return and remove it at any time without
notification.
ALWAYS engage your own lock and tag to the lock-out
device…

Lock out procedure
If an employee or contractor has left his/her lock on a ride or attraction, every effort must be made
to contact this person, and VERIFY his/her location. This contact can occur in person or via telephone BUT MUST BE DONE! If contact cannot be made, a full inspection of the Ride or Attraction including
all ride enclosure areas must be made and documented.
The removal of a lockout device by any person other than the employee or contractor that applied the
device must be approved by the Maintenance Manager and or the Park Operations Manager.
The employee or contractor whose lockout device was removed must be informed of his/her lock being
removed before resuming work.
A master list and key information will be maintained by Park Operations, Ride and Attraction
engineering and facilities maintenance, so that each device can be identified and removed should it be
necessary. This information shall have limited access.
Get insights. Get educated. Get inspired.
Lock out procedure
The employee will be issued the only key for the lock.
The lock and/or key are not transferable, and the lock is
to be attached and removed only by the person to whom
it was issued.
Use of the lock for purposes other than lockout or use by
someone other than the employee who was issued the
lock, is prohibited.
If a key to a lock seems to be lost beyond recovery, the
person to whom the lock was assigned shall notify
his/her supervisor and a replacement lock and key shall
be issued.
