Benzene

Properties: colorless volatile organic compounds, with special aromatic odour;

Main hazards: carcinogenic substances, mild poisoning can cause sleepiness, headache, dizziness, nausea, chest tight feeling, etc, and may have mild mucosal irritation symptoms.

Severe toxic can appear fuzzy, breathing appeared dull or washed out light and fast, arrhythmia, convulsions and coma.
