THIS REFERS TO ANY SITUATION IN WHICH A HORIZONTAL LIFELINE IS PERMANENTLY INSTALLED. OVERHEAD SYSTEMS ARE OFTEN USED FOR PEOPLE UPON BULK TANKS, BUT THERE ARE MANY OTHER POSSIBLE APPLICATIONS.
BE SURE THAT WHEN YOU INSTALL A HORIZONTAL LIFELINE, YOU HAVE ENOUGH FREE FALL DISTANCE. SEE THE SPECS OF THE MANUFACTURER OF YOUR HLL.
(+) A. ANCHOR POINT/ANCHOR FACILITY OR SUPPORT STRUCTURE
Anchor points or structural anchor facilities have to meet the strength requirements related to EN-795(2012).
Static strength test: 12 kN. Keep in mind that a safety factor of 2 is a normal minimal requirement. Manufacturers have all kinds of requirements, varying from 12 kN to 25 kN and incidentally even more.
We advise to use 24 kN as a basic guiding idea for discussing and analyzing strength requirements ( = minimal breaking strength). From there you may apply them to specific cases.
This can have consequences for the choice of anchor systems and also the choice of ppe. For more guidance, please contact us.
For horizontal lifeline systems a safety factor of 2 with regard to the mandatory shock impact calculations is necessary. This implies that stronger structural constructions may be necessary for the safety of the system.
In case of questions or doubts: please call for advice. It is possible to meet requirements with additional measures of the choice of ppe items, or smart, specific constructional measures. But this needs more than just clicking buttons on a website.
SPECIFIC REMARKS FOR THIS CASE:
• TEMPORARY HORIZONTAL LIFELINES NEED A CERTIFICATE OF CONFORMITY TO EN-795(2012)-C, OR CLASS D. CLASS C: HLL IS MADE OF STEEL WIRE ROPE. CLASS D: HLL IS A RAIL.
• ANCHORAGE SUPPORT STRUCTURE OR SUPPORT CONSTRUCTIONS: MINIMAL STRENGTH MUST BE 2 X THE STRENGTH REQUIREMENT AS SPECIFIED BY THE MANUFACTURER OF THE HLL.
(+) B. BODY SUPPORT
Basic requirement for any harness is conformity to EN-361.
If you need to do work positioning additional conformity to EN-358 is needed.
Suspension work implies harness conformity to EN-813.
SPECIFIC REMARKS FOR THIS CASE: BASICALLY ANY HARNESS WHICH CONFIRMS TO EN-361 IS OKAY.
(+) C. CONNECTOR
Lanyards, fall arrest blocks, ropes with fall arresters, karabiners, ascenders, descenders, etc..
SPECIFIC REMARK FOR THIS CASE:
A FALL ARREST BLOCK MAY BE THE BEST POSSIBLE CONNECTING DEVICE, BECAUSE OF THEIR SHORTER FALL DISTANCE.
(+) D. DESCENT or rescue
Rescue of a fallen person: Basic principle is that a rescue must be done within 15 minutes after a fall. The capacity to perform rescue after a fall is a basic legal responsibility.
SPECIFIC REMARK FOR THIS CASE:
CUSTOMERS OFTEN CHOOSE FOR A FALL ARREST BLOCK WITH A BUILT-IN DESCENT FUNCTION. IT ARRESTS THE FALL, AND IT PROVIDES THE RESCUE BY ITSELF. AFTER THE INITIAL ARREST OF THE FALLEN PERSON THE BLOCK LOWERS THE VICTIM WITH A CONTROLLED DESCEND SPEED OF ABOUT 0.9 MTR/SEC.
(+) E. EDUCATION
Instruction / training. These are basic legal responsibilities. We can train and instruct you wherever you need it: at one of our training centers, or at your location, or wherever worldwide. Please contact us.
(+) F. FACTS
How to make sure that your safety measures are up to date: Records and documents must be stored adequately, with regard to legal responsibilities and product liability of the manufacturers / suppliers.
Periodical inspection: Anything related to personal fall protection has to be inspected at least 1 x every twelve months.
