This is from the article:
State and federal protocols demand the body be in a coffin of noncorrosive metal that weighs four times the individual’s body weight, said Gary Collins, burial at sea coordinator for the Environmental Protection Agency’s southeastern district in Atlanta.
The coffin also must be secured top, bottom and lengthwise. “We recommend they use stainless steel chains,” Collins said. “The idea is to make sure it keeps that casket closed This has happened before, where the lids pop open.”
The coffin also must have at least six 2-inch holes drilled in its lid and base. It can be sunk no closer than three miles from shore in international waters of at least 600 feet. Because of a casket’s weight, burials at sea typically require a crane-equipped boat.
Make sure the “sinking devices” are Coast Guard Approved.
Interesting.
