Hazards:
- DGFVML: dust, gas, fumes, vapour, mist, liquid
- Irritation, Itching, Burning, Breading a person, Fire, Explosion, Inhalation, Radiation
- Two important hazards: Health hazards, fire & explosion hazards
- Chemical hazards: any chemical that presents a physical hazard or a health hazard
Hazards associated with chemicals: (classification of hazardous substance)
- Irritant: Non-corrosive which through immediate prolonged or repeated contact with skin or mucus membrane may cause inflammation e.g. petrol
- Corrosive: Substance which can contact with living tissues may destroy by burning e.g. Acid
- Harmful: Substance which swallowed, inhaled or penetrates the skin may cause damage
- Boiling point: The pump at which a liquid boil at atmosphere pressure (100 f’)
- Combustible materials: A combustible material, a substance that catches fire & burns easily above 400 c’
- Flammable: material that will burn with ignited at or below room temperature
- Cryogenic Columns: liquid, solid, gases, & naphtha
Some chemical knowledge:
- Hydrocracking is a catalyst chemical process used in petroleum refineries for converting (in the catalyst used Alumina Balls)
- Amine used for H2S tripping
- CCR, continuous catalyst regeneration (or Reformer)
- Naphtha is lighter than gasoline
- CHMC. Chemical hazards management chart
- Chemical PPEs: chemical splash face shield
- Handling corrosive materials, the best gloves are Rubber, Neoprene, and vinyl.
- MSDS not older than 3 years
