SafetyCâu 646 / 700
A worker on a wall form uses a device that holds them in place and lets them lean back to work hands-free, limiting any fall to no more than 2 feet. This describes which system?
a.A personal fall arrest system
b.A travel restraint system that prevents reaching the edge at all
c.A positioning device system, which supports the worker and limits a free fall to about 2 feet
d.A safety monitoring system
Giải thích
Correct: a positioning device holds a worker in place on a vertical surface and is limited so a free fall cannot exceed about 2 feet. A fall arrest system stops a longer fall (up to 6 ft free fall) after it starts. Travel restraint keeps a worker from ever reaching the edge, not leaning against a support. A safety monitor is a person watching for hazards, not a device.
