Question #363

Which activity is particularly dangerous when working at maximum outreach?

Która z czynności jest szczególnie niebezpieczna podczas wykonywania prac na maksymalnym wysięgu?

a
drilling holes in a ceiling

wiercenie otworów w suficie

Correct answer

b
drilling holes in a wall

wiercenie otworów w ścianie

c
chiselling a wall

kucie w ścianie

d
both b and c are correct

odpowiedź b i c jest prawidłowa

Why?

Pushing a drill against the ceiling transfers an additional downward force onto the platform. At maximum outreach (maksymalny wysięg), this force acts through the longest lever arm and increases the overturning moment. Wall work also needs care, but this question concerns maximum outreach rather than maximum height.
