Full-body harnesses

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.

A system used to arrest an individual s fall. It consists of a substantial anchorage, full body harness, and lanyard, and may include a deceleration device, lifeline, or suitable combinations of these. The components are sometimes referred to as ABCs, i.e., A for anchor point means, B for body harness, and C for connecting device (lanyards). See also ASSE Z359.1, Safety Requirements for Personal Fall Arrest Systems, Subsystems, and Components Fall Restraint System. 

A line or rope secured to an anchor point or lifting device outside a confined space and attached to a full body harness, chest harness, or wristlets worn by an individual entering the space, for the purpose of pulling the individual out of the confined space. See also Confined Space.

Residential construction poses special concerns for contractors. One of the biggest concerns is falls, so OSHA requires fall protection that meets the residential construction requirements of 29 CFR 1926.501(b)(13). According to the regulation, residential construction employers generally must ensure that employees working six feet or more above lower levels use conventional fall protection methods, including guardrails, safety nets, or personal fall arrest systems. A personal fall arrest system may consist of a full body harness, a deceleration device, a lanyard, and an anchor point. (See the definition of personal fall arrest system at 1926.500).

Body belts versus full body harnesses. 

Components There are several components that form a fall protection system. Together they prevent or limit falls. The person who might fall wears a safety belt or safety harness. Standards limit the deceleration force for body belts to 10 times the force of gravity or less. Higher stopping forces are likely to cause injuries. For a full-body harnesses, the deceleration limit is 35 times the force of gravity. Body harnesses distribute the stopping forces more effectively and reduce the likelihood of injury from the stop. 

MSA s EVOTECH full-body harness offers advanced design features that improve user comfort, ease of use, durability and user safety. The harness is RFID enabled, offering the Field ID Safety Network with Field ID access to provide a reliable, online inspection and safety compliance (ISCM) management system.

Climbers will inspect and then don proper fall-arrest equipment, including a full-body harness, double lanyards with one-hand operation, and an ascender/ descender (slider) device if the structure is equipped with a fall-arrest rail in good working condition. 

Effective January 1,1998, body belts are not acceptable as part of a personal fall arrest system. Note The use of a body belt in a positioning device system is acceptable. The full body harness is now the order of the day. After aU, fallen workers could only hang about 1 minute, 30 seconds until they pass out from pooUng of blood in their extremities and at times they actually slid from the belt and fell the remaining distance to the ground or surface. Rescues could not be performed in such a short time. 

The belt itself often caused injuries to the back, etc. when workers fell. The full body harness, similar to a parachute harness, allows for a worker to hang in it upon a fall for some 30 minutes before it starts to become imcomfortable and rescue can usually transpire in that amount of time. The full body harness is actually a piece of equipment with a tag containing its serial number and other information for tracking purposes. The requirement for full body harness was viewed by workers as being impractical, uncomfortable, or cumbersome to work while wearing it. At worksites today, it does not pose these problems and is an important part of a fall protection system (see Figure 25.12). 

Boatswain s chair means a single-point adjustable suspension scaffold consisting of a seat or sling (which may be incorporated into a full body harness) designed to support one employee in a sitting position. 

A. Shock absorbing lanyards are not mandatory but are often used to comply with OSHA s fall protection requirements. The specifications for a personal fall arrest system are in 29 CFR 1926.502(d). One of the provisions in this section requires that when using a full body harness, the system must limit the maximum arresting force exerted on an employee to 1,800 pounds. One means of complying with this section is to use a shock absorbing lanyard. 

Retrieval system—The equipment, including a retrieval line, chest or full-body harness, wristlets (if appropriate), and a lifting device or anchor (usually a tripod and winch assembly), used for non-entry rescue of persons from permit spaces. 

Each authorized entrant shall use a chest or full body harness, with a retrieval line attached at the center of the entrant s back near shoulder level, or above the entrant s head. Wristlets may be used in lieu of the chest or full body harness if the employer can demonstrate that the use of a chesf or full body harness is unfeasible or creates a greater hazard, and that the use of wristlets is the safest and most effective alternative. 

The entrant must wear a full body harness and lifeline so that he or she can be easily pulled from the space. It can be attached to a block and tackle or a winch system that a single rescuer/attendant can operate from outside the space. 

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. 

A personal fall arrest system consists of three components, each of which is equally important the full body harness, the lanyard, and the anchor point. The harness fits around the person s legs, over their arms and around their body. The D-ring is located on the harness between the person s shoulder blades and this is where the lanyard is attached. Should a fall take place, the person will be suspended in the harness. 

The equipment provided for use by backup personnel should be covered by the maintenance manual and work permits. Such equipment includes the protective equipment necessary for entry and the gear required for rescue of personnel from the confined space. The latter includes chain falls, lifelines, and harnesses. These devices must be securely fastened outside the space. The best choice will depend on the shape of the access port(s). In the case of a closed vessel provided with one or more manways, for example, a wrist harness may be preferable to a full-body harness. The latter may make it very difficult to remove a person who is badly injured or unconscious. 

Entry rescue. Entry reseue should be a last resort and only used if self-rescue and non-entry are impossible. A trained workerfs) will enter the confined space to rescue the trapped person. Entry rescue workers are put at considerable risk and should wear proper fall protection equipmrat, such as a full-body harness connected to a winch and davit systan. Make sure the rescuer is trained on the proper respiratory protection for entry rescue. 

A full body harness must be worn and a lanyard attached to the boom or basket when working from an aerial lift.
