Yellowknife (Feb 20/04) - Due to a recommendation from Health Canada, health care workers across the territory are taking part in a training program to ensure N95 masks are fitted and worn properly to enhance staff protection.

The procedure has been legislated under the Canadian Occupational Health and Safety Standards because of the recent SARS outbreak, said Donna Stanley-Young, acting occupational health and safety nurse.

"These are the masks that staff would wear if caring for a patient with respiratory ailments," said Stanley-Young. "The tuberculosis rate in the NWT is five times higher than the rest of Canada."

Face shapes

The Department of Health and Social Services contracted Linda Obermeyer, an occupational health and safety professional from Calgary, to instruct five Stanton staffers. They will in turn train and fit other staff members in phases.

"Everyone has a different-shaped face," said Stanley-Young. "It is important they know how to correctly wear the mask."

Initially, a sensitivity test is conducted on everyone using a formula called Bitrex, a bitter food additive. The individual wears only a hood and is given constant sprays until they are able to taste the solution in their mouth.

"The average person takes about three to four sprays," said Obermeyer.

Once they have determined the sensitivity level, a mask is placed over the face and the procedure is repeated, increasing the number of sprays and having the person move their head from side to side and up and down, as if they are performing work-related duties.

Everyone trained

Natasha Finch, clinical co-ordinator in the pediatrics unit, was one of five being tested on Feb. 17. She said the mask was a perfect fit for her now that she is familiar with the proper procedures.

"I didn't taste anything at all," she said. "I felt the mask move slightly (when my head went up and down), but it didn't break the seal."

Obermeyer has already trained people in Hay River, and will head to Fort Smith and Inuvik when finished in Yellowknife.

All staff, including housekeeping and maintenance staff at the hospital require the training.

"If they have to go into a patient's room, they must know the proper procedure," said Stanley-Young.
