Who directs the alternate safe route around a suspected MPPEH site?

• A. The first responder on site directs it.
• B. Site Safety directs alternate safe route.
• C. The person who discovered it directs it.
• D. EOD directs it from a distance.

Answer: (B)

Directing the alternate safe route around a suspected MPPEH site is the responsibility of Site Safety because they manage risk on the ground and control access to the hazard area. They assess the environment, coordinate with the EOD team, marshal resources, place barriers as needed, and communicate the approved route to personnel so everyone can move safely around the site. The first responder handles initial actions and scene security, the person who discovered it reports the hazard, and EOD oversees the disposal work; none of these alone is tasked with establishing the designated safe path, which is a role held by Site Safety.
