recommended (by the manufacturer) five minutes before open-
ing the hood to allow the parts to come to a stop. When the
employee opened the hood, the flywheel struck the edge of the

Those with severe allergies to insect stings
should consult a physician about carrying
a prescription medical kit. The kit contains
medicine and instructions to be used if the
person is stung. If the kit is used, the victim
still must receive medical attention. Call for
help or take them to the nearest hospital.
