o Asphyxiation hazardo pH control

• Materials Used• Personal Protective Equipment (PPE)

17

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

20

Personal Protective Equipment • Body protection

o Eyeo Faceo Respiratory o Feet o Hands

• Hazardous waste operations

• Training provided to workers so they know what PPE applies to the type of work they do
