Evergreen Pyrethrum Dust is an all natural product and the ingredient from it comes from the crysanthymum plant. You would want to use the same precautions with an all natura product as you would any other insecticide or even house cleaning product. Take care to follow the instructions on the label and only use in areas it designates is safe for use. If it touches your skin, wash your skin with soap and hot water to remove it. Any side effect to a human would vary on the human and their sensitivity to the product.
