WHY SHOULD YOU ADJUST YOUR HARD HAT SO IT FITS PROPERLY？ Two colleagues are heading for a construction site. Robert：Let’s go to the worksite and see the progress. Ben：OK, you must remember to wear a hard hat. Robert：[1] Ben：Of course. Hard hats are important for protecting your head in open environments. Robert：Is my hat on properly？ Ben：[2] First of all, adjust the suspensions. Robert：I want the hat to fit comfortably so it doesn’t fall off, but I don’t want to make it so tight that it causes discomfort. What should I do？ Ben：You can adjust the chinstraps properly to fit around your chin. Robert：I see. Do you have any more information about safety？ Ben：[3] because after years of wear and tear, the entire suspension system may need replacing. Robert：[4] Ben：And do not stuff the gaps of a hard hat or make changes to the hat’s suspension harness. Otherwise, its effectiveness will be impacted. Robert：[5]Now I know how important a hard hat is in the high-hazard construction industry!
