Tank Asset Management Plan (TAMP)

The importance of good information and well executed Tank Asset Management is critical, and provides exceptional value.

The absence of well performed Tank Asset Management Plan can have cost implications that far exceed, by an order of magnitude, the investment required for the planning, inspection, preventative maintenance and execution of a Tank Asset Management Program. Over the life of the Township of St. Clair elevated tank asset, improper recommendations and poor management of can cost significantly more than a scenario where the best information is generated and the best practices are executed.

Landmark provides the comprehensive analysis, planning and communication plans that will facilitate the best Tank Asset Management value.

Landmark is best positioned to provide this service to the Township of St. Clair. We are fully invested in world class asset management strategies. We know the product (elevated tank) better than anyone in the world. We invented the Composite Elevated Tank and have designed and constructed most of them. With respect to water storage, we have well developed in-house expertise in planning, design, project management, fabrication, construction, maintenance, operations and water quality. Our coatings capabilities – inspection, system design, application and Quality Management are world class. And we are accustomed to managing high levels of risk effectively for the best financial outcome.

Fixed Rail Ladder (FRL) Fall Protection System

Hazard summary

A worker descending a vertical ladder on a water tower in 2014 was critically injured after falling five metres while properly using a Class Frontal-Fixed

Rail Ladder (Class FRL) Fall Protection System. A Class FRL Fall Protection System is a type of vertical fall protection using a permanently installed

metal rail anchoring system with an automatic fall arresting device called the "trolley" or "carriage".

The investigation revealed a weakness in the design of some Class FRL Fall Protection Systems, which may not adequately protect workers who fall

backward or who squat and roll backwards into a fall while connected by a body harness to the trolley which slides along the vertical rail. If a worker

leans back, the trolley’s internal braking system can be pulled off the rail, allowing the trolley to slide down the rail. If a worker falls backwards or squats

and rolls backward into a fall (as opposed to falling straight down or inwards towards the ladder) the trolley may not lock, allowing a worker to fall

freely. In the 2014 incident, the worker fell from a water tower ladder as shown in Figure 1.

Figure 1: How the water tower worker fell

A. The worker is descending properly using the fall protection system.

B. The worker bends at the waist.

C. The worker’s legs fold into a squat position while the worker’s hands catch the next rung. The squat position allows the trolley to travel below the

height of the worker’s knees.

D. As the worker begins to roll backward their hands release from rung, and the tension in the trolley connection increases enough to remove all the

slack out of the full body harness and slide the chest D-ring towards the waist.

E. This tension in the connection to the trolley forces the worker into a tight squatting position while rotating around the rung that the worker’s feet

are on.

F. The trolley connection remains in tension as the trolley travels below the rung that the worker’s feet are on.

G. The connection to the trolley, now in tension between the worker’s legs prevents the engagement of the braking mechanism that would stop the

workers motion.

H. The worker, with back to the ladder, continues to fall head first while still attached to the fall protection system.

In 2010, the Ministry of Labour published a similar Alert, Class Frontal Fixed Rail Ladder (FRL) Fall Protection System, Alert #26/0510, after a worker

was injured after falling back, then down 20 metres from a ladder attached to a tower while using a Class FRL Fall Protection System. In 2010, the

investigation determined that the Class FRL Fall Protection System might not adequately protect workers who fall backward in a standing position.

Locations and sectors

Page 1 of 2Alert: Fixed Rail Ladder (FRL) Fall Protection System | Ministry of Labour

6/9/2014http://www.labour.gov.on.ca/english/hs/pubs/alerts/a26.php

Class FRL Fall Protection Systems are used on vertical access ladders which normally do not have a cage, such as the ladders on communication towers,

chimneys and water tanks (towers).

Precautions

Even though a Class FRL Fall Protection System may be currently certified to CSA standards and/or have a CSA standards stamp on the side of the

trolley unit, this should not be interpreted to guarantee worker safety and employers should not rely on such a stamp. Further investigations into the

system are needed to ensure the system protects against a squatting position/rollback fall or a fall backwards.

Class FRL Fall Protection Systems whose design characteristics require the connection between the worker and the trolley to be in tension and where the

trolley remains disengaged regardless of the tension force applied should not be used. Employers must take reasonable precautions to protect workers in

these circumstances. This may include using alternative fall protection or access systems, as appropriate, for the adequate protection of the health and

safety of workers using vertical access ladders.

Employers who own or rent structures which have a Class FRL Fall Protection System installed must ensure that the Class FRL Fall Protection System is

capable of protecting a worker in the case of a squatting position/rollback fall or a fall backwards. The Ministry recommends that employers contact the

manufacturer to ensure that the particular Class FRL Fall Protection System is capable of protecting a worker from any type of fall (including a backward

fall and falling from a squatting position) before it is used.

Note: This Alert replaces the Class FRL Fall Protection System, Alert #26/0510 published in 2010 by the Ministry of Labour.
