Yes, a personnel door can be installed in a shipping container. The opening must be measured on the actual unit, framed so the altered wall transfers loads appropriately, weather-sealed and matched to the way people will use the space. If the container will be occupied rather than used only for storage, the door is one part of a larger local building, fire, accessibility and egress review—not proof that the conversion is approved.
Size the personnel door around the trip through it
Choose the wall bay on the real container
A personnel-door frame is part of the modification
Threshold, landing and water deserve equal attention
Hardware follows the user and security plan
Separate fabrication acceptance from occupancy approval
A concise acceptance record prevents later guesswork
Send the fabricator the doorway job, not only a door size
Share the container photos, wall location, user movement, required clear opening, site landing and intended storage or occupancy use. Ask for framing, sealing, coating, hardware and acceptance tests as separate quoted items.
