B) Double-rail
C) Triple-rail
D) Quadruple-rail

Answer :

Final answer:

B) Double-rail. Guardrails on suspended scaffolds made after 2000 must be double-rail with a midrail for worker safety.

Explanation:

The guardrails on suspended scaffolds manufactured after the year 2000 must be double-rail, with midrails installed approximately halfway between the top rail and the platform surface. This requirement is in place to ensure the safety of workers operating on scaffolds by providing a sturdy barrier that can prevent falls. The top rail should be able to withstand, without failure, a force of at least 200 pounds applied within two inches of the top edge, in any outward or downward direction, at any point along the top edge.
