A steel edge with radius R = 0.5 mm, without burr, was employed in this case. Based on this

test, the equipment is suitable in corresponding composition to be used over similar edges

(inquire with the manufacturer about this), such as are existing for example on rolled-steel

profile sections, on timber beams or on encased, rounded roof parapets.

Despite this test, in case of horizontal or sloped employment where a risk of fall over an edge

exists, the following must be considered as mandatory:

1. If the risk assessment carried out before the start of work indicates that the fall-zone

edge relates to a particularly ‘cutting’ and/or ‘non-burr free’ edge (e.g. an uncovered

parapet, trapezoid sheeting or a sharp concrete edge) then

•

appropriate arrangements should be made before the start of work so that a

fall over the edge is ruled out

•

an edge protector should be installed before the start of work or

•

contact should be made with the manufacturer.

2. The anchor point of the flexible guide may not lie below the platform (e.g platform, flat

roof) of the user.

3. The deflection at the edge (measured between the two legs of the flexible anchor

line) must be at least 90°

4. The

required clearance

below the edge is at least

5 m

5. The subsystem is always to be employed so that no untensioned rope arises. A

length adjustment may be implemented only if the user does not move in the fall edge

direction in this case.

6. In order to limit a pendular fall, the working area and/or lateral movements from the

central axis to both sides should, in each case, be restricted to 1.50 m. In other

cases, no individual anchoring points rather e.g. fastening devices of Class D

according to DIN-EN 795 are to be employed.

Note:

In the case of a fall over an edge, there is a risk of injury during the harnessing

action as a result of the falling person crashing into structural members and/or

structural parts.

8. Special rescue measures should be defined and exercised for the event of a fall over

the edge.

Function and application

In case of the use of lanyards (e.g. safety ropes) with more than two meters length, fall

arresters must be used. With use according to specification, these have the task of

preventing, as far as possible, any untensioned rope buildup possibly arising due to too large

rope lengths. This reduces the fall height of a possible fall.

The accompanying fall arrester MAS SK 12 (S 16) is an appliance which can be employed

especially for upward and downward movements. In this case, the accompanying fall arrester

moves automatically on a flexible anchor line during ascension (rope diameter coordinated to

the device type and fabricated completely by the manufacturer) which is held to a large

extent tight either through the fastening of a weight or through a dead weight on the ground.

In case of a fall from a height, the impact is reduced to less than 600 KG (EN 353/2) by the

shock absorber.

The application of this fall arrester is therefore employed mainly as a sub-system of personal

protective equipment in the ascent area against fall from a height, since the user can either

use both hands for his own safety or, however, one hand for carrying light materials or tools.

This accompanying fall arrester is to be used exclusively with full body harnesses, suitable

for the application, tested in accordance with DIN - EN 361. Also the mass of the user,

including tools and other materials, must be considered here.

Notes on use

Use of the accompanying fall arrester with vertical application

The accompanying fall arrester type MAS SK 12 (S 16) is supplied ready fabricated by the

manufacturer, i.e. at the end of the flexible anchor line an end security element has been

attached, so that the accompanying fall arrester cannot slide unintentionally.

With fastening the accompanying fall arrester, it is to be ensured that the arrow ("above") on

the device always points in the direction of the fastening point.

Furthermore, the connecting element at the beginning of the flexible anchor line must be

checked for correct seating and close-off.

The operation of this accompanying fall arrester manually for downward movement may be

implemented only with a secure base for stance. If this is not considered, danger to life exists

since the fall arrester does not lock in case of a trip fall.

The accompanying fall arrester is always supplied with a shock absorber sewn on at the ring

eyelet (length 0.44m) with connecting element (max. length of the shock absorber including

the connecting elements: 0.57 m). This connecting element is fastened into a reception

eyelet of the full body harness and must be checked for secure seating and closure. Here, if

possible, the front reception eyelet should be selected. The shock absorber may not be

either manipulated or made longer, since an increased drop height would result from that and

thus a failure of the fall arrester, or it can lead to the impacting of the body on objects or the

ground as a result of the greater fall distances.

Open space below the feet of the user:

In case of flexible guides with larger lengths (> 15.0 m), the necessary open space to be

expected due to the rope extension below the feet of the user according to the fall distance

increase is to be determined. The manufacturer provides information about this.

The anchor point for the flexible anchor line must be located above the user, if possible in a

vertical arrangement (see directions for use General - Anchor point).

Use of the accompanying fall arrester with horizontal application

The accompanying fall arrester, including flexible guide, was also tested for horizontal

employment and a fall over an edge was successfully simulated.
