1. GLOSSARY

Breaking Strain: The average load at which a new component (for example: a cable or chain

assembly) will fail. The breaking strain is obtained by applying direct tension to a component at a uniform rate of speed, in a testing machine.

Chute: A series of linked chute sections that are used to convey debris.

Chute Hoist: An engineered device that has been designed specifically to raise, anchor,

and lower a chute. A chute hoist consists of a support frame and a winch apparatus. The support frame, with the winch apparatus removed, can also be referred to as a chute hoist.

Chute Sections: Modular conical tubes that can be linked together in series to form a chute.

Chute System: A suspended chute and the anchors (including chute hoists) that support it.

Design Factor: Also known as the “safety factor”, it is a product’s theoretical reserve

capacity. The design factor is calculated by dividing the Breaking Strain by the Working Load Limit. The design factor is generally expressed as a ratio, for example: 10 to 1, or 10:1.

Working Load Limit:

The maximum load which can be applied to the component, when the

component is new, or in “good as new” condition, and when the load is applied in-line, with respect to the centerline of the component. This term can be abbreviated to WLL.

5. THE CABLE ASSEMBLY

THE VITAL COMPONENT

Every Superchute are used to link one chute section to the next.

The cable assembly pair is the vital component of a chute section. Each pair supports the weight of the chute sections beneath. Therefore, the uppermost pairs on a suspended chute support more weight than cable assembly pairs located lower down on the chute.

Consequently, if your chute will mix Superchute assemblies, plan to put the sections with the older cable assemblies at the base of the chute. This action will put the stronger cable assemblies at the top of the chute, where they are most needed.

THE CABLE ASSEMBLY (continued)

NEW HEIGHT & WEIGHT LIMITS OF CHUTE SECTIONS

Over time changes have been made to the cable assembly. As well, new height and weight limits are in effect. Check the date stamp on every chute section to understand your new height

& weight limit:

a) If the chute section was manufactured in February 1999 or later, and is equipped with the original cable

assemblies, it can carry a maximum of 60 sections (200 feet, 60 meters) or 2000 lb. (900 kg) of chute,

whichever is reached first.2

b) If the chute section was manufactured between June 1996 and February 1999, and is equipped with the

original cable assemblies, it can carry a maximum of 30 sections (100 feet, 30 meters) or 1000 lb. (450 kg) of chute, whichever is reached first.3 If you would like to be able to build a taller chute (up to the limits described in “a)” above), contact the factory for retrofitting of the cable assemblies.

c) If the chute section was manufactured prior to June 1996, and is equipped with the

original cable assemblies, it can carry a maximum of 15 sections (50 feet, 15 meters) or 500 lb. (225 kg) of chute, whichever is reached first.4 The cable assemblies of these sections feature lightweight, metal alloy clips stamped with the words “KONG – BONAITI - ITALY” (shown on the right). The KONG clip is much weaker than the forged ones currently used. The three possible colors of the KONG clip are:

If you have chute sections equipped with cable assemblies that use KONG clips, and would like to be able to build a taller chute (up to the limits described in “a)” above), contact the factory for retrofitting of the cable assemblies.

THE GATE OF THE “KONG” CLIP MUST CLOSE FULLY. If the gate is not fully closed, its strength is greatly reduced. Oil the gate hinge and spring regularly. Discard cable assemblies whose clip gates do not spring shut.

The above information applies to new, undamaged cable assemblies working together in pairs. Abuse or wear and tear will reduce the strength of the cable assembly. If you are unsure of the strength of your cable assemblies, please call the Superchute

Notes:

As of June 1996 the month and year of manufacture have been branded into every chute section.

ATTACHMENT TO THE CHUTE WALL

Prior to installing a chute section, ensure that two cable assemblies are fastened securely to the chute wall.

Please note that Wraparound cable assemblies attached to the chute wall. This shipping method keeps the sections from shifting in transport.

Attach cable assemblies to the chute wall using the instructions shown below and on the next page (these instructions are included with every pair of packaged cable assemblies).

• A loosely attached U-Bolt could undo and cause the failure and collapse of the chute.

• A falling chute system can cause serious injury and death.

• Attach each cable assembly to the chute wall, per the diagram

MAINTENANCE

Check the condition of the cable assemblies on each chute section regularly:

• Replace cable assemblies that show signs of wear.

• Replace cable assemblies that have been strained.

• Oil the clip’s gate hinge and spring regularly. The gate must spring closed.

• For forged clips, spare gate springs can be purchased from Superchute

• Replace damaged cable assemblies with new, authentic Superchute

• Always change the full cable assembly, not just a part of it.

• Keep a written register, with dates and signatures, of all maintenance operations: record and

identify chute sections whose cable assemblies have been upgraded (or downgraded). Engrave a code or date into the plastic chute wall adjacent the cable assembly, or attach a durable identifying tag to the cable assembly.

Discard The Entire Cable Assembly If Any Of The Following Conditions Are Discovered:

THE WIRE ROPE:

• There are 3 or more protruding broken wires within a 2 inch (5 cm) interval.

• There are broken wires near attached fittings.

• The wire rope has kinks, birdcages, twists, or other distortions.

• The wire rope has been stretched.

• The wire rope is corroded.

• The thimble is loose and rattles in cable eye.

• The pressed sleeve is cracked, loose, or damaged.

THE U-BOLT GROUP:

• The U-bolt is bent, cracked, or damaged. • Pieces are missing from the U-Bolt Group.

THE CABLE ASSEMBLY (continued)

CAUTION!

Certain factors can be abusive and lessen the load that the cable assembly (and by extension, the chute section) can withstand. Some examples are:

• twisting of the cable assembly

• disfigurement, deterioration by straining, usage, weathering, heat, and corrosion

• rapid application of load or jerking

• the application of excessive loads

Keep corrosive substances away from the cable assemblies, and do not weld near the chute system.

Some types of damage may not be visible to the eye. Consider the following example:

Incident: A blockage occurred in a tall chute. The blockage went unnoticed and workers

continued to introduce debris into the chute. The installers had calculated the weight of the unblocked chute to be 1500 lb. (680 kg).

Debris continued to accumulate in the chute until the blockage was finally discovered by the inattentive safety monitor. A crane was called in and the entire chute was lowered to the ground. The crane’s load indicator showed the total weight of the chute and blocked debris to be 15,000 lb. (6800 kg).

Upon inspection of the cable assemblies, no obvious signs of strain were noted. The chute sections were equipped with cable assembly pairs having a combined working load limit of 2000 lb. (900 kg). The breaking strain of the cable assembly pairs is 20,000 lb. (9000 kg).

Action: Although the cable assemblies showed no obvious sign of strain, the working

load limits were greatly exceeded. All the cable assemblies should be replaced.

Conclusion: If, during the course of your job, the working load limits of the cable assemblies

are accidentally exceeded, consult a structural engineer and the Superchute factory to determine whether the chute sections in that system must be refitted with new cable assemblies.

WARNING

6. SELECT AN INSTALLATION AREA

Choose the installation area carefully. A poor choice can create a hazardous chute system.

Use the following guidelines when choosing the site for your chute installation.

1) SAFETY OF THE PUBLIC: The chute should be located in an area far from the public. Always consider the consequences of a worst case scenario. For example:

• If the chute collapsed (due to a blockage that overloaded the cable assemblies) would it fall across a high traffic area, over a road, over a pedestrian walkway?

• If a worker tossed a brick into a top hopper or door section, but missed, what could be the consequence of the brick falling outside the chute?

• If a hole wore through the chute wall, and debris escaped from the chute, would the debris shower the public below?

2) SHELTER FROM THE WIND:

• Select an area that provides shelter from the PREVAILING wind.

• Building corners that protrude outwards tend to accelerate the wind.

Due to this effect, do not place the chute within 20 feet (6 meters) of a protruding building corner.

• Inset corners generally provide

excellent shelter from the wind. Whenever possible, install the chute in an inset corner (see sketch).

• The effect of wind on the chute is

discussed in Section 10: Installation, under the heading: “Wind & Restraint Issues”.

(continued)

3) ELECTROCUTION: Prevent electrocution by choosing an area that is free of electric cables. If cables are present, contact your local electrical authority before proceeding.

4) THE CHUTE MUST HANG VERTICALLY: To reduce the risk of a blockage, choose an area where the chute will hang vertically. Horizontal displacement of the chute must not exceed 20% of the chute’s height. See the sketch below.

If the chute does not hang vertically, debris will rub against the chute wall. This friction will cause the speed of the moving debris to decrease, possibly to the point where debris stops moving, thereby creating a blockage.

(continued)

BLOCKAGE HAZARDS

• If the chute is not hung vertically, there will be a bend in it.

• If the bend is too sharp, when users introduce debris they will clog the chute. If

the blockage is not noticed and more debris is introduced, the total weight of the chute will rapidly increase, and the chute system could collapse.

• A collapsing chute system can cause serious injury and death.

• Do not create a blockage hazard:

1. Choose a location that will allow the chute to hang vertically.

2. Choose a location that will not crimp or constrict the chute.

INSTALLATION (continued)

ANCHOR THE CHUTE SECTIONS

Superchute using your own method, please be advised of the following guidelines:

chute hoists can be used to safely anchor a chute. If you wish to anchor your chute

• A sufficiently strong anchorage must be present in order to anchor

the chute to the building. At the window, roof, or floor slab level, locate structural members of the building that are strong enough to anchor your chute.

• The anchors must be able to support at least three times the weight of

the chute.

• A structural engineer must verify the adequacy of the anchors and

supporting structure.

• Use rated rope to anchor the chute. 5/8” (16 mm) diameter nylon

rope, rated to 10,000 lbs. (4500 kg), works well for this task.

• Use recognized safety knots, such as the bowline or the figure eight,

for all rope work.

• Anchor the chute to structural members of the building according to

instructions provided in the sub-section: Wind & Restraint Issues.

In the sketch above, two “piggybacked” Bolt-Down Frames are used to anchor the chute.

INSTALLATION (continued)

USING A SCAFFOLD, STAGE, OR PLATFORM AS AN ANCHOR

• If a scaffold, suspended stage, platform or similar structure is used to support the chute, and a blockage occurs in the chute, the additional weight could cause the structure to topple or fail.

• The collapse of the support structure and chute could cause serious injury or death.

• The support structure must be capable of holding at least five times the weight of the chute, in addition to being able to hold the weight of men, machinery, and materials with an adequate safety factor.

• A structural engineer must verify the adequacy of the support structure.

Additional Guidelines For Chutes Anchored To Scaffolds:

• The scaffold should be installed by professional scaffold

erectors.

WARNING

• The scaffold should be erected and tied in accordance with

government regulations and manufacturer’s instructions or as designed by an engineer.

• The chute must be restrained to the scaffold at intervals of

less than 25 feet (8 meters), in order to prevent wind sway.

The sketch on the left shows the chute installed inside the scaffold. This arrangement is best as it distributes the weight of the chute evenly on the scaffold.

INSTALLATION (continued)

WIND & RESTRAINT ISSUES

Because a chute installation may remain in place for days, weeks, or months, the installers must consider how the chute will be affected by winds. Installers should also expect that strong winds could arrive at times when there are no supervisors or workers on the job (ie: overnight or on the weekend).

The way in which the chute will react to winds depends on how it was restrained, and the spacing interval between restraints.

The installer can use either taut restraints. The following two pages explain this concept further.

But first, take a look at the sketch below. It shows the potential effect of using the wrong type of restraint. Why is the hoist pulled over? Note the hoist tie-backs, and their help in this instance.

TAUT RESTRAINTS

If the installer can access the entire length of the chute, use taut restraints. If the chute is anchored to a scaffold, use taut restraints. Secure the chute tightly to the building structure, at intervals of 25 feet (8 meters) or less, using a 5/8” (16 mm) diameter nylon rope or equivalent.

As the sketches show, the closely spaced restraints hold the chute tight to the building structure, preventing the wind from moving the chute.

SLACK RESTRAINTS

If the restraint intervals will be more than 25 feet (8 m), use slack restraints to secure the chute to the building structure. Slack restraints keep the chute from acting like a taut sail by allowing it the freedom to form an arc and move up and down. Do not mix slack and taut restraints.

The attachment of the chute’s discharge end to the container (or other anchor) must be considered a restraint. Use Container Cord. Do not tie it tightly as the chute must be able to move if heavy winds arise.

If the wind strengthens, the strain could cause the Superchute beneficial, as the chute will be released and failure of the hoist will be avoided.

USE A SAFETY ROPE

If a major problem arises and the chute collapses, it could fall away from the building the way a tree falls when cut at the trunk. Prevent a chute from falling this way by using a Safety Rope.

In the event of a collapse, a chute equipped with a Safety Rope is forced to fall the length of the rope, thus keeping it close to the building.

Follow this procedure when installing a Safety Rope:

1. Secure the rope to a 5000 lb. (2250 kg) capacity anchor above the

anticipated height of the chute system. Do not secure the rope to a chute hoist or to an anchor that is used or will be used for any other application. If the rope must lie across a working floor, then consider using wire rope as it will better resist people treading on it.

2. Lower the end of the rope to the ground.

3. Pass the rope through several clips (the number of clips will depend on the

length of the chute).

4. As the chute is raised and added to, attach a clip to the U-bolt of every third

chute section.

5. The clips will slide up the rope, rising with the chute sections to which they

were attached.

6. Tie the rope snugly and securely to the last chute section.

(Coil any unused rope on the side).

7. If the chute collapses, it will fall along the rope.

THE CONTAINER

• The debris exiting the chute will be directed into a suitable steel container. A dump-truck, or

similar loading vehicle, is not suitable because falling material can present a hazard to the truck operator.

• Barricade the container area (see page 47 for details).

• Tie the chute’s discharge end to the container using one or two lengths of Superchute®

Container Cord (provided free of charge with every chute order). Unlike Regular cords and ropes, Container Cord is designed to fail. If a full container is accidentally driven away with the chute still attached, the Container Cord will fail and the chute system will not be pulled from the building.

• Do not double up the Container Cord or use more than one or two lengths to attach the

chute’s discharge end to the container. The effect would be to increase the strength of the attachment, which would make it less likely to fail if it should need to do so. See the sketches below.

Å RIGHT

The chute is tied off to the far end of the container. This arrangement allows the end of the chute to be easily moved about the container, and provides a desirable level of slack for any strong winds.

FIRE PREVENTION

To prevent a container from catching fire and subsequently setting fire to the building and/or the suspended chute (which could also introduce smoke into the building), users and installers must take all of the following precautions:

1. Keep the contents of the trash container wet at all times (the Superchute

Drencher is available for this purpose). Water application will also help control dust. Do not apply water if the temperature drops below the freezing point, or if the container contains hazardous debris (the runoff could be toxic).

2. Make provisions for water

application on all floors with exposure to the chute.

3. Install the container at least

10 feet (3 meters) away from the building (check local by-laws).

4. Seal the container with a

fireproof lid (example: metal sheets) at the end of each workday.

5. Move the base of the chute 10 feet (3 meters) away from the container at the end of each

work day, or, disconnect the last 10 feet (3 meters) of chute at the end of each work day.

6. Post clear signs around the trash container and on all floors facing the chute. Indicate:

GENERAL INSTRUCTIONS

Failure to adhere to these instructions could result in injury and/or death.

• Barricade the container area in order to protect

workmen and the public from any material that may ricochet out of the container. Build the barricade using plywood sheets, screens or similar materials.

In the event that debris is accidentally thrown into the chute when the discharge end of the chute is not directed into the container, or the container has been removed, the barricaded area may help to prevent injury.

• Do not introduce concrete blocks, spikes, flammables, or toxic dusts. Do not drop more than

50 lb. (23 kg) of debris at a time into chute. Do not use motorized loaders to introduce debris into the chute (motorized loaders introduce too much debris, too quickly).

• Never stand under, or look up the discharge end of a chute.

• Never look into, or place body parts into the opening of a Door section.

The Safety Monitor will ensure:

• The chute was installed and is used according to the instructions provided by Superchute® Ltd.

• The chute is tied properly to the container with Container Cord.

• The chute is untied from the container before the container is moved or changed.

• The container contents are kept wet to reduce airborne dust and the risk of a fire.

• The container is not overfilled.

• Any spaces between the chute openings and the building edge are covered over.

• Debris is seen to fall clear of the chute’s discharge end.

• Warning gates are used at the correct times.

• All components of the chute are kept in good working condition as the job progresses.

• A means of communication with other job site workers exists.

• Empty debris containers are readily available.

• All work is conducted in a safe and responsible manner.

• Fall protection safeguards are used.

• Chute blockages are the most frequent problem encountered by chute users.

• If a chute blockage is not noticed and more debris is introduced, the total weight

of the chute will rapidly increase, and the chute system could collapse. A collapsing chute system can cause serious injury and death.

Horizontal displacement of the chute must not exceed 20% of the height. Have the chute reinstalled if it does not meet this criteria.

• Make sure the chute is not bent over balconies, shelves,

or similar structural protrusions. These obstructions could crimp the chute and lead to a blockage. Have the chute reinstalled if it is bent or crimped.

• Only introduce debris with dimensions that are less

than half the diameter of the chute. For example: if using a 30” (76 cm) diameter chute, the maximum allowable dimensions of the debris are 15” x 15” x 15” (38 cm x 38 cm x 38 cm).

• Do not use motorized loaders to introduce debris into

the chute (motorized loaders introduce too much debris, too quickly).

• Break-up debris before throwing it into the chute.

• Move the discharge end around the container to prevent

it from clogging as the container fills.

• Inspect the chute for blockages frequently.

• Designate a safety monitor who will, in addition to

monitor for blockages, supervise the safety of the entire debris removal operation.

• Use load cells to monitor the chute weight and detect

blockages (see page 42 for more load cell information).

USAGE INSTRUCTIONS (continued)

IF A BLOCKAGE OCCURS

1. Stop putting debris into the chute.

2. The chute system could collapse without warning.

Evacuate the area below the chute of people. Consider that the path of destruction created by a collapsing chute could be equivalent to its height.

3. Use a crane with ample capacity to lower the entire chute to the ground.

4. Separate the chute sections on the ground.

5. Remove the blockage.

6. Consult a structural engineer and the Superchute

factory to determine if the

anchors and cable assemblies were strained:

• If the engineer concludes the cable assemblies were strained, order new

cable assemblies from your Superchute factory.

• If the anchors were strained, rig new anchors.

• If the engineer concludes the anchors and cable assemblies were not

strained, reinstall the chute system.

12. A LETTER FROM OSHA

OSHA

March 25, 1992

Mr. Andrew Anson, President Superchute

Dear Mr. Anson:

This is in response to your February 10 letter requesting the Occupational Safety and Health Administration (OSHA) to review the design of a debris chute manufactured by Superchute

As you know, it is the policy of the Occupational Safety and Health Administration not to approve or endorse products. The variable working conditions at jobsites and possible alteration or misapplication of an otherwise safe product could easily create a hazardous condition beyond the control of the product manufacturer. However, we have reviewed the information provided in your letter and evaluation report and it appears that if properly installed and maintained and not used to load trucks the Superchute is being used to load trucks where falling material can present a hazard to the truck operator then a substantial gate and employee to operate the gate would be required by 29 CFR 1926.852(c).

If we can be of any further assistance, please contact Dale Cavanaugh of my staff at (206) 553-5930.

Sincerely,

Patricia K. Clark, Director Directorate of Compliance Programs

13. OSHA REGULATIONS FOR CHUTES

From OSHA Regulations (Standards – 29 CFR) Part 1926 Safety and Health Regulations for Construction

These are the OSHA regulations for chutes:

Subpart H - Materials Handling, Storage, Use, and Disposal

1926.252 - Disposal of waste materials (partial copy)

(a) Whenever materials are dropped more than 20 feet to any point lying outside the exterior walls of the

building, an enclosed chute of wood, or equivalent material, shall be used. For the purpose of this paragraph, an enclosed chute is a slide, closed in on all sides, through which material is moved from a high place to a lower one.

Subpart T - Demolition

1926.852 - Chutes (complete copy)

(a) No material shall be dropped to any point lying outside the exterior walls of the structure unless the area

is effectively protected.

____________________________________

(b) All materials chutes, or sections thereof, at any angle of more than 45 degrees from the horizontal, shall

be entirely enclosed, except for openings equipped with closures at or about floor level for the insertion of materials. The openings shall not exceed 48 inches (122 cm) in height measured along the wall of the chute. At all stories below the top floor, such openings shall be kept closed when not in use.

____________________________________

shall be assigned to control the operation of the gate, and the backing and loading of trucks.

____________________________________

(d) When operations are not in progress, the area surrounding the discharge end of a chute shall be securely

closed off.

____________________________________

(e) Any chute opening, into which workmen dump debris, shall be protected by a substantial guardrail

approximately 42 inches (107 cm) above the floor or other surface on which the men stand to dump the material. Any space between the chute and the edge of openings in the floors through which it passes shall be solidly covered over.

____________________________________

(f) Where the material is dumped from mechanical equipment or wheelbarrows, a securely attached toeboard

or bumper, not less than 4 inches (10 cm) thick and 6 inches (15 cm) high, shall be provided at each chute opening.

____________________________________

(g) Chutes shall be designed and constructed of such strength as to eliminate failure due to impact of

materials or debris loaded therein.

14. FALL PROTECTION AND OSHA

The following three pages refer to OSHA Regulations (Standards – 29 CFR) Part 1926 Safety and Health Regulations for Construction Subpart M - Fall Protection

1926.500 to 1926.503

WARNING

WRONG RIGHT

NO FALL PROTECTION FALL PROTECTION IN PLACE

• A person can easily fall from a building if the floor edge they are working near does not offer fall protection safeguards.

• A fall from a height of 6 ft. (1.8 meters) is enough to cause serious injury or death.

• Use a personal fall arrest system (example: body harness and lanyard) when working near a floor edge that does not offer proper fall protection.

• OSHA requires that fall protection barriers be at least 42” high, plus or minus 3” (107 cm, plus or minus 8 cm). Guardrail systems, parapet walls, and window sills may be acceptable fall protection barriers provided they meet OSHA’s height and strength criteria.

• Read and understand the OSHA fall protection regulations (a few of the regulations are provided on the next two pages).

53 Help Line: 800-363-2488 October 15th, 2001

FALL PROTECTION (continued)

The Fall Protection System shown below incorporates the following features:

FALL PROTECTION FOR PEOPLE:

(1) TOPRAIL “shall be 42” (107 cm) plus or minus 3” (8 cm) above the walking/working level”

(2) MIDRAIL “shall be installed at a height midway between the top edge of the guardrail

system and the walking/working level, when there is no wall or parapet wall at least 21” (53 cm) high”.

(3) OPENINGS “Other structural members shall be installed such that there are no openings in the

guardrail system that are more than 19” (48 cm) wide.

FALL PROTECTION FOR OBJECTS:

(4) TOEBOARD “shall be a minimum of 3.5” (9 cm) in vertical height from its top edge to the level

of the walking/working surface. It shall not have more than ¼” (6 mm) clearance above the walking/working surface”.

(5) SCREENS Openings around Top Hopper and Door sections must be covered over using

screens, boards, or plywood to prevent debris from falling outside the chute.

(6) BUMPER A solid bumper, not less than 4” (10 cm) thick and 6” (15 cm) high, prevents

wheelbarrows from breaking through and falling over the edge.

“Guardrail systems, when used for falling object protection, shall have openings small enough to

prevent passage of falling objects”

October 15th, 2001 Help Line: 800-363-2488 54

FALL PROTECTION (continued)

These are a few of the OSHA regulations for Fall Protection:

“The employer shall determine if the walking/working surfaces on which its employees are to work have the strength and structural integrity to support employees safely. Employees shall be allowed to work on those surfaces only when the surfaces have the requisite strength and structural integrity.”

“Each employee on a walking/working surface ... with an unprotected side or edge which is 6 ft (1.8 meters) or more above a lower level shall be protected from falling by the use of guardrail systems, safety net systems, or personal fall arrest systems.”

“An unprotected side or edge means any side or edge ... where there is no wall or guardrail system at least 39” (1 meter) high.”

“Each employee in a hoist area shall be protected from falling 6 feet (1.8 meters) or more to lower levels by guardrail systems or personal fall arrest systems. If guardrail systems ... or portions thereof, are removed to facilitate the hoisting operation ... and an employee must lean through the access opening or out over the edge of the access opening (to receive or guide equipment and materials, for example) that employee shall be protected from fall hazards by a personal fall arrest system.”
