FARIBAULT (AP) -- Faribault Middle School students are fragrance-free.

The school may be the only one in the state to ban perfumes and colognes. But students have adapted since the policy was imposed four years ago.

Only two or three have been asked to leave a classroom this year for violating the no-smell rule. Students are asked to wash off the scent and are allowed to get new clothes from home. The school also will provide t-shirts for students who can't get a change of clothes.

Enforcement of the policy is a "judgment call," Principal Jill Lauters said. It's usually aimed at repeat offenders, she said.

The policy developed after complaints by students and teachers of headaches and nausea led to a study of air quality in 1993. The school's ventilation system was improved and carpeting was removed.

Eventually, the school's site council, comprised of parents, teachers and staff members, decided to also ban fragrances on students and teachers.

"I kind of agree with it because it gets smelly," said Tara Chichester, a sixth-grader.

Shelley Tougas, spokeswoman for the Minnesota School Boards Association, said, "This is the first I've heard about (a fragrance-free school), but I'm not surprised because environmental sensitivity is growing."

If interest grows, the association may draft a model fragrance-free policy for other schools to use.
