A fall arrest system is employed when a worker is at risk of falling from an elevated position. A positioning system restrains the elevated worker, preventing them from getting into a hazardous position where a fall could occur, and also allows hands-free work. Both systems have three components harnesses or belts, connection devices, and tie-off points. 

A tie-off point is where the lanyard or lifeline is attached to a stmctural support. This support must have a 5,000-pound capacity for each worker tying off. Workers must always tie off at or above the D-ring point of the belt or harness. This ensures that the free fall is minimized, and that the lanyard doesn t interfere with personal movement. Workers must also tie off in a manner that ensures no lower level will be struck during a fall. To do this, add the height of the worker, the lanyard length, and an elongation factor of 3.5 feet. Using this formula, a six-foot tall worker requires a tie-off point at least 15.5 feet above the next lower level. 

For confined space applications, a tripod and winch system is used as both the tie-off point and connection device. It is used in conjunction with a full-body harness to lower and raise workers into tanks or manholes. Never use a material-handling device for personnel unless it is specifically designed to do so.

OSHA s Appendix C to Subpart M says the following about tie-off points ... 

This causes a serious injury hazard if the worker unknowingly uses a lanyard capable of absorbing only a 6-foot free fall (the most common lanyard). With the new labeling, the user will now be able to easily identify the 12-foot free fall lanyard from the 6-foot free fall lanyard. (Please note that the 6-foot free fall capable lanyard, that is 72 inches long, is only allowed when the tie-off point is at the D-ring elevation or higher. Consult with your lanyard supplier for more information. 

As with any large, multi-floor facility, the BNC has general safety concerns related to electrical hazards, fall protection, confined-space entry, and similar hazards. While all of these hazards were addressed in the design of the facility, only the specialized hazards related to a high-technology research facility will be addressed in this chapter. For example, the design of tie-off points throughout the facility was critical for the safe repair of equipment, but this is a standard consideration in all facilities and so is not included here. 

No offense, but I think yours would be too big for me. Fm not siu-e I could adjust it to fit, Paul said. Besides, I don t think there s a suitable anchor point to tie-off to. ... 

This allows us to actively influence the location of the pseudoproduct point of the intermediate section in order to maintain sharp separation (i.e., separation at which the intermediate section trajectory ends at some boundary element of the concentration simplex). This is feasible in the case when inside concentration simplex there is one trajectory of reversible distillation for pseudoproduct point x ) that ends at mentioned boundary element, and there is the second trajectory inside this boundary element. To maintain these conditions, pseudoproduct point x j) of the intermediate section should be located at the continuation of the mentioned boundary element, because only in this case can liquid-vapor tie-hues in points of reversible distillation trajectory located in this boundary element he at the lines passing through the pseudoproduct point x jy. We discuss these conditions in Chapter 4. It was shown that in reversible distillation trajectory tear-off point x[ev e from the boundary element the component absent in it should be intermediate at the value of the phase equUibrium coefficient between the components of the top product and of the entrainer rev,D > Kevj > Kev.s)- This condition is the structural condition of reversible distillation trajectory tear-off for the intermediate section. Mode condition of tear-off as for other kinds of sections consists of the fact that in tear-off point the value of the parameter (LfV) should be equal to the value of phase equilibrium coefficient of the component absent at the boundary element in tear-off point of reversible distillation trajectory ((L/V)m =... 

Proper hook-up, anchoring and tie-off techniques, including the proper dee-ring or other attachment point to use on the body belt and harness for fall arrest ... 

The question often comes up, My employees do have to access that platform but we can t install guardrail since they would be in the way of performing the work. Can the employees wear a proper fall protection harness and tie-off to an anchorage point ... 

OSHA allows employees to tie-off if there is no way to install guardrails. The key here is to protect employees from fall hazards. Remember though, that fall protection harnesses have to fit properly and a suitable anchorage point (meeting the OSHA requirements of Subpart M of 1926) must be tied off to. When using a personal fall arrest system, a full body harness is required. Body belts have not been permissible for many years as part of a personal fall arrest system. 

Tie-off (anchorage) points on scaffold tubing are acceptable provided that the scaffold is tied in to a structure and that the tie-off is made on horizontal members only (transoms, ledgers or guardrails) with no joint in the same bay. 

The use of safety harnesses by all those working from MEWPs should be made mandatory they should be tied off at an appropriate point within the platform.
