GHS symbols
Explosive, corrosives, flammables, environmental hazards, oxidizers, toxins (acute), irritants,
gasses (pressure), specific toxicity
Seni'zer
Chemical that causes significant allergic reac'on in normal 'ssue
Poison
Fatal to human health
Toxic
Causes adverse human reac'on in 'ssue
Corrosive
Destroys living cells
Flammable
Easily ignites or burns
Vola'le
Liquids that vaporize easily
Oxidizer
Rapidly oxidizes, receives/donates electrons during oxida'on
Gas
Gas under pressure
, Precision
The reproducibility of a measurement; calculated by average devia'on or standard devia'on
Accuracy
The closeness of a result to the true value; calculated by percent error
GHS Symbols and NFPA Fire Diamond
Fatal - Health
Aqua'c toxicity - No NFPA
Oxidizer - Special Hazard
Carcinogen & Toxic - Health
Flammable - Flammability
Irritant - Health
Explosive - Instability
Gas under Pressure - No NFPA
Corrosive - Health
SDS
- 0.1% known chemicals have safety data sheets
- Chemical suppliers creates SDS
- SDS are not required to be accurate, one should examine SDSs from different manufacturers
- SDS are wri<en for an industrial se=ng, because of this chemicals hazards and personal
protec've equipment requirements may be overstated
Steps for using SDS
- Compare label info
- Determine the hazard class
- Look at the procedures
In the event of a spill
- If splashed with a large quan'ty of a chemical, use the shower immediately
- Eyewashes should be used for at least 15 minutes
- Contaminated clothing must be removed and treated as waste
- Use a small brush and dustpan when cleaning up a solid
- Use a spill pillow to absorb liquids with nontoxic vapors
- If solid is spilled on skin wash scrape off, then wash with water
