Accepted Answer

1600°F (871°C)

Question 2

When multiple retorts are operated simultaneously, what is the primary concern regarding air supply?

Accepted Answer

Shared combustion air may be insufficient for both units

Answer

Simultaneous operation of multiple retorts can strain a shared air supply system, potentially causing incomplete combustion in one or both units.

Question 3

After cremation is complete, what is the proper term for the bone fragments remaining before processing?

Accepted Answer

Cremated remains

Answer

The correct term for all human remains after cremation, including bone fragments before and after processing, is 'cremated remains.'

Question 4

Which condition in the retort most commonly causes incomplete cremation and dark smoke emissions?

Accepted Answer

Insufficient afterburner temperature

Answer

An insufficiently heated secondary (afterburner) chamber fails to combust particulates and gases, resulting in dark smoke and incomplete cremation.

Question 5

What action should an operator take if they discover a pacemaker in the deceased that was not noted on the authorization?

Accepted Answer

Remove it before cremation and document the discovery

Answer

Pacemakers must be removed before cremation because they can explode and damage the retort; the discovery must be documented and communicated to the family.
