SafetyCâu 523 / 700
A worker will use a portable electric tool outdoors in a damp area. Which electrical safety measure is MOST important to prevent shock?
a.Remove the ground pin so the plug fits any outlet
b.Use ground-fault circuit interrupter (GFCI) protection and inspect cords for damage before use
c.Wrap the connection in cloth tape and keep working
d.Run the tool from a longer, thinner extension cord
Giải thích
Cal/OSHA requires GFCI protection for temporary power in construction, especially in wet or damp locations, because a GFCI quickly cuts power on a ground fault and prevents electrocution; cords must also be inspected for damage. Option b is correct. Removing the ground pin (a) defeats a key safety feature, cloth tape (c) is not a proper repair, and an undersized cord (d) overheats and risks fire.
