Hey im back with a new unit requested by one of my followers, i posted what i thought was unit 10 in my profile recently, but i noticed that the assignment had nothing to do with what my subscriber asked, that is because when i did the course this unit (using science in the workplace) was my unit 2...
Demonstrate safe working practices in a scientific workplace.
Risk Assessment Demonstration
Ex. carrying out a experiment involving flame, or materials which
are corrosive or flammable, A fire that began when a researcher
in a chemistry lab accidentally broke a bottle of a flammable
solvent closed parts of the main campus for several hours, or
like when a bunsen burner has been ignored, or we are dealing
with a flammable chemical near a flame, also using Hydrochloric
acid, and not using the right protection.
Use of Flammable
corrosive Corrosive materials, are able to attack and chemically destroy
chemicals exposed body tissues, it also damages or even destroy metal.
The damage, begins when the material touches skin, eyes,
respiratory tract, digestive tract, or metal.
They might be hazardous in other ways too, depending on the
particular corrosive material.
Usually, and most of corrosives can be either acids or bases.
Common acids include hydrochloric acid, sulfuric acid, nitric acid,
chromic acid, acetic acid and hydrofluoric acid. Common bases are
ammonium hydroxide, potassium hydroxide (caustic potash) and
sodium hydroxide (caustic soda).
Other chemicals can be corrosive too. Check the supplier labels on
chemical product containers.
It is wise to treat unknown materials as very hazardous until they
are positively identified.
Corrosive materials are present in almost every workplace. Acids,
bases (which include caustics or alkalis), and other chemicals may
be corrosive. Everyone who works with corrosives must be aware
of their hazards and how to work safely with them.
