What Is An Unsafe Blood Pressure

Nitrate negatives - museum to copy, destroy unsafe items

The negatives, made from cellulose nitrate, can burst into flames at temperatures as low as 120 degrees Fahrenheit and can give off toxic gases as they decay.

Thus, officials at the county-owned museum plan to ask for permission to dispose of the negatives – but not before making digital copies of the images that can be safely stored and made available to the public.

The item is on the consent agenda for Monday's meeting of the New Hanover County Commissioners. County Manager Bruce Shell has urged the item be approved.

The issue came up when the Cape Fear Museum began updating its disaster preparedness plan.

"We probably have some artifacts of a hazardous nature," said curator Barbara Rowe.

Except for a few old rifles, most of the items on display in the museum at 814 Market St. – from the diorama of the Battle of Fort Fisher to Chicken Hicks' shag-dancing shoes – look relatively harmless. But you might be surprised.

Recently, for example, the museum was offered an antique sphygmomanometer, a cuff for measuring blood pressure. It turned out that rubber on the device was rotting, allowing toxic mercury to leak out.

Rowe politely declined the donation and advised its owner on how to dispose of it safely.

As staff members checked the collections, attention soon focused on 76 photo negatives stored in the museum's refrigerator.

According to museum registrar Terri Hudgins, the negatives were found in a box of old books from an estate sale in the Porters Neck area. A supporter bought them and donated them to the museum in 1998.

The negatives have no captions, and the people in them are unidentified. Still, the photo images – which date from around 1910 – have considerable value in illustrating daily life from a quieter time.
