2.0 System Use

2.1

FALL PROTECTION AND RESCUE PLAN:

The employer must have a Fall Protection and Rescue Plan. The plan should

provide guidelines and requirements for an employer’s managed fall protection program, including policies, duties and

training; fall protection procedures; eliminating and controlling fall hazards; rescue procedures; incident investigations;

and evaluating program effectiveness.

2.2

INSPECTION FREQUENCY:

SRDs shall be inspected by the authorized person

or rescuer

before each use (See Table

3). Additionally, inspections shall be conducted by a competent person

other than the user. Extreme working conditions

(harsh environment, prolonged use, etc.) may necessitate more frequent competent person inspections. The competent

person shall use the

Inspection Schedule (Table 2)

to determine appropriate inspection intervals. Inspection procedures

are described in the

Inspection & Maintenance Log (Table 3)

. Results of the Competent Person inspection should be recorded

in the

Inspection and Maintenance Log

or recorded with the Radio Frequency Identification (RFID) system.

2.3

NORMAL OPERATIONS:

Normal operation will allow the lifeline to extend and retract with no hesitation or slack as

the worker moves at normal speeds. If a fall occurs, a speed sensing brake system will activate, stopping the fall and

absorbing much of the energy created. Sudden or quick movements should be avoided during normal work operation, as

this may cause the SRD to lock up. For falls which occur near the end of the lifeline travel, a reserve lifeline system or

Energy Absorber has been incorporated to reduce the fall arrest forces.

2.4

BODY SUPPORT:

A Full Body Harness must be used with the Self-Retracting Device. The harness connection point must be

above the user’s center of gravity. A body belt is not authorized for use with the Self-Retracting Device. If a fall occurs when

using a body belt it may cause unintentional release or physical trauma from improper body support.

2.5

COMPATIBILITY OF COMPONENTS:

Unless otherwise noted, 3M equipment is designed for use with 3M approved

components and subsystems only. Substitutions or replacements made with non approved components or subsystems may

jeopardize compatibility of equipment and may affect safety and reliability of the complete system.

2.6

COMPATIBILITY OF CONNECTORS:

Connectors are considered to be compatible with connecting elements when they

have been designed to work together in such a way that their sizes and shapes do not cause their gate mechanisms to

inadvertently open regardless of how they become oriented. Contact 3M if you have any questions about compatibility.

Connectors (hooks, carabiners, and D-rings) must be capable of supporting at least 22.2 kN (5,000 lbs). Connectors

must be compatible with the anchorage or other system components. Do not use equipment that is not compatible.

Non-compatible connectors may unintentionally disengage (see Figure 5). Connectors must be compatible in size, shape,

and strength. Self-locking snap hooks and carabiners are required. If the connecting element to which a snap hook or

carabiner attaches is undersized or irregular in shape, a situation could occur where the connecting element applies a

force to the gate of the snap hook or carabiner (A). This force may cause the gate to open (B), allowing the snap hook or

carabiner to disengage from the connecting point (C).

2.7

MAKING CONNECTIONS:

Snap hooks and carabiners used with this equipment must be self-locking. Ensure all

connections are compatible in size, shape and strength. Do not use equipment that is not compatible. Ensure all

connectors are fully closed and locked. 3M connectors (snap hooks and carabiners) are designed to be used only as

specified in each product’s user’s instructions. See Figure 6 for examples of inappropriate connections.

Do not connect snap hooks and carabiners

A. To a D-ring to which another connector is attached.
B. In a manner that would result in a load on the gate. Large throat snap hooks should not be connected to standard

size D-rings or similar objects which will result in a load on the gate if the hook or D-ring twists or rotates, unless the

snap hook is equipped with a 16 kN (3,600 lb) gate.

In a false engagement, where size or shape of the mating connectors are not compatible and, without visual

confirmation, the connectors seem fully engaged.

D. To each other.
E. Directly to webbing or rope lanyard or tie-back (unless the manufacturer’s instructions for both the lanyard and

connector specifically allows such a connection).

F. To any object which is shaped or dimensioned such that the snap hook or carabiner will not close and lock, or that

roll-out could occur.

G. In a manner that does not allow the connector to align properly while under load.

1 Authorized Person:

A person assigned by the employer to perform duties at a location where the person will be exposed to a fall hazard.

2 Rescuer:

Person or persons other than the rescue subject acting to perform an assisted rescue by operation of a rescue system.

3 Competent Person:

An individual designated by the employer to be responsible for the immediate supervision, implementation, and monitoring of the employer’s

managed fall protection program who, through training and knowledge, is capable of identifying, evaluating, and addressing existing and potential fall hazards, and

who has the employer’s authority to take prompt corrective action with regard to such hazards.
