physical and chemical are two
There are two categories of experiments: laboratory and field.
GHS has more than 3 categories. Basically we can consider groups as Labels and Safety Data Sheets (SDS). Each group contains many classes. Within the GHS classification system, there are three major hazard groups:Physical hazards.Health hazards.Environmental hazards
1: chemical 2: physical 3: mechanical 4: biological 5: phychosocial
Atmospheric and non-atmospheric
Geological, Geomorphic, Atmospheric or Ecological
Awareness, educational, avoidance
if u spill some sort of drink on a computer it is most likely to break
Exposure to Chemical Hazards. Exposure to blood-borne pathogens
The most important rule for laboratory safety is "Know the hazards of what you are working with." The next most important rule is "Know how to protect yourself from the hazards of the materials you are working with."
well, most have natural disasters to watch out for while others have dangerous chemicals in the laboratory to deal with.
* Fire and explosion hazards * Health hazards
A hazard is an article, substance or condition that has the potential to harm. Although there are many hazards that you will come across, hazards are generally put into TWO main categories not three: 1.Unsafe Acts - messing around at work, running, not paying attention. 2.Unsafe conditions - bad lighting, slippery surfaces, trailing cables. After defining what the hazard is , you will need to look at the risk associated with the hazard i.e the likelihood of harm occurring
