Final answer:
A personal fall arrest system is a set of components used to prevent falling from heights, while a travel restraint system is designed to restrict a worker's movement to prevent them from reaching a fall hazard.
Step-by-step explanation:
Understanding Personal Fall Arrest and Travel Restraint Systems
A personal fall arrest system is a safety apparatus designed to securely catch a person in the event they fall from height while working. This system typically includes a full-body harness, an anchorage point, and a connector such as a lanyard or retractable lifeline. Its main purpose is to prevent a worker from hitting the ground or a lower level, minimizing the risk of serious injury or fatality.
A travel restraint system, on the other hand, prevents a worker from reaching a position where there is a risk of falling. It typically involves the use of a harness, tether, and anchorage points to restrict the range of movement to safe areas of work.
Both fall arrest and travel restraint systems are vital components of workplace safety, particularly in industries such as construction, where working at height is common. These systems have been developed in response to a historical lack of safety concern for workers in hazardous positions, exemplified by the figure 10.9 image depicting construction workers with proper protective equipment.
