A humanitarian warehouse was working at what it described as "full capacity" on Monday, as aid officials called for full access to the Gaza Strip.

Workers at UNICEF’s Supply Division warehouse on the outskirts of the Danish capital, Copenhagen, packed health, hygiene, and medical kits - along with winter clothes - into boxes.

UNICEF senior emergency manager Emma Maspero said the UN children’s aid organization had 1,300 trucks of supplies "ready to go into Gaza", with a further 1,000 trucks on the way.

"Our focus is on being able to deliver the supplies directly into children and their families' hands. So, we are very much hopeful about the ceasefire and the access to be able to get supplies across the border,” Maspero told The Associated Press.

UNICEF’s Supply Division warehouse covers 20-thousand square meters and is almost completely automated through a combination of conveyors, robots and a winding monorail.

Packed boxes are stored in a towering 24-meter-high High Bay area, where up to 36-thousand pallets can be stored, carefully placed on racks and retrieved by eight computer-controlled robotic cranes.

Elsewhere, two robots continuously pack pallets.

This sprawling facility, run by the UN children’s agency, produces and ships more than 50 different kits for emergency health, midwifery and education.

Kits include everything from soap and toothpaste for hygiene to puppets and ball games for children, plus classroom equipment and a chalkboard for schooling.

On Monday, workers packed parts of the Interagency Emergency Health Kit, designed to serve a population of 10-thousand people for up to three months.

"This kit is comprised of a lot of consumables that will already have been used up in trauma medical settings,” explained Maspero.

“There's a lot of gauze, there's cannulas for IVs, there's syringes, there's sutures and needles for surgical stitching and basic medical equipment to be able to keep running primary healthcare and surgical facilities."

Humanitarian organizations have said they are preparing to surge aid into the Gaza Strip, especially food that’s been in short supply in many areas.

On Friday, UNICEF executive director Catherine Russell called for “all crossings into Gaza” to be opened immediately to allow the flow of humanitarian aid, essential goods and critical supplies.

Maspero said they are still hoping for that level of access.
