Hazard: High

• Acute toxicity hazard- oral, dermal, inhalation
• Corrosive to metals
• Skin corrosion hazard
• Aquatic toxicity hazard
• Serious eye damage
• Oxidizer
• Specific organ toxicity- thyroid, respiratory system
• Electric shock hazard
• Inhalation hazard

Effectiveness: Good

• Results are clearly observable without guidance
• Good connection from demo to course material
• Clear contrast between systems behavior
• Time to results is medium
• Good reliability
• Primary effects
• Mild effects observed by audience

Difficulty: High

• Multi-step procedures with varying results depending on the order or amount of reagent addition
• Reactions containing toxic compounds
• Demos that require training or practice
• Simple manipulations for most to perform

Safety Precautions:

• Eye protection required
• Gloves required
• Perform in a well-ventilated area
• Use of UL approved three-prong plug and outlet
• Absorbent materials on hand
• Sodium bicarbonate on hand
• Avoid exposure to dusts, mists, and droplets
• Prevent release of reagents to the environment
