Emergencies & Hazards第 95 / 120 题
You are securing a single 12-foot pipe weighing 1,800 pounds on a flatbed. How many tiedowns are required at minimum?
a.One tiedown
b.Two tiedowns
c.Three tiedowns
d.Four tiedowns
解析
An article longer than 10 feet needs two tiedowns for the first 10 feet plus one more for each additional 10 feet or fraction, so a 12-foot article needs three. One tiedown is only allowed for articles 5 feet or shorter and 1,100 pounds or less, and four exceeds the minimum for this length.
