Things to avoid

• Don't put vaseline, mineral oil, oil-based sunscreen or moisturizers on skin as they can trap chemicals.
• Don't wear contact lenses, which can trap irritating chemicals underneath.
• Don't wear things which can easily be grabbed (i.e. dangly earrings or other jewelry, ties, loose hair).
• Don't go to the demo alone, if you can help it - go with an affinity group or some friends who know you well.
• Don't forget to eat food and drink lots of water.
