FALL ARREST
As a general rule, it is recommended that a fall arrest system be used at working heights of four feet or more. This system consists of:
• anchorage/anchorage
connector
• body wear (full-body
harness)
• connecting device |
POSITIONING/
RESTRAINT*
A positioning/restraint system is used to hold a worker in place while allowing a hands-free work environment at elevated heights and/or restrict the worker's movement to prevent reaching a location where a fall hazard exists. A typical positioning/restraint system consists of:
• anchorage/anchorage
connector
• body wear (full-body harness
or body belt)
• connecting device
(positioning lanyard) |
SUSPENSION
Suspension systems are used widely in the window washing and painting industries and are designed to lower and support a worker while allowing a hands-free work environment. A typical suspension system would include:
• anchorage/anchorage
connector (anchor bolt,
trolley, carabiner, etc.)
• body wear (full-body
harness)
• connecting device
(workline)
• suspension device
(bos'n chair) |
RETRIEVAL
The retrieval system is primarily used in confined space applications where workers must enter tanks, manholes, etc. and may require retrieval from above should an emergency occur. A retrieval system typically consists of:
• anchorage/anchorage
connector (tripod, davit)
• body wear (full-body
harness)
• connecting device
(retractable lifeline/
retrieval unit) |
