Lesson 1Safety checks before family arrival: collapse risk, utility checks, access routesThis lesson details pre-arrival safety checks, including soil stability, collapse risks, buried utilities, vehicle and pedestrian access, and emergency planning, to ensure the site is secure and respectful before the family arrives at the graveside in New Zealand conditions.
