Safety Precautions - H2SO4
• Hazardous in case of skin or tissue contact, ingestion, and inhalation
• Carcinogen
• Toxico Kidneys, lungs, heart, CVS, upper respiratory
tract, eyes, and teeth
• Degradation of health if prolonged exposure o Such as spray mist
• Corrosive, poisonous liquido If large spill, clean with dry earth, sand, or
other non-combustible material18
Safety Precautions - NaOH and FeCl2• Eye contact can result in corneal damage or
blindness
• Skin contact can produce inflammation and blistering
• Inhalation of dust will produce irritation to GI or respiratory tract
• Severe over-exposure can produce lung damage, choking, unconsciousness, or death
• Nonflammable
• Corrosive
19
Safety Precautions - PAM
• Irritationo Eyeo Skino Digestive and Respiratory Tract
• Potential Cancer Hazard
• Storageo Protected from lighto Cool, dry, well-ventilated area
