True or false: WHMIS pictograms will always be found in combination. correct answers False,
they can be found as needed: alone or in combination.
How many pictograms would a compound that is corrosive, toxic causing harm, and flammable
have? correct answers 3

The pictograms represent ________________ of a compound. correct answers physical hazard
characteristics
True or false: the lower the category number, the greater the hazard. correct answers True.
Hazard 1A is more hazardous than Hazard 3B
What are risks of a compressed gas? correct answers physical hazard (tanks are heavy)
-explosive hazard (if tanks are heated, dropped, or impacted)
-content hazard (could be flammable or poisonous)
What are some precautions that should be taken with compressed gas? correct answers - secure
cylinder to prevent from falling
- avoid heat and ignition sources (increases tank pressure)
- transport and move carefully
Compressed gasses should be stored in a _______ and ______________ area. correct answers
cool and ventilated
,What are 3 examples of compressed gasses? correct answers N2 gas tanks
CO2 gas tanks
O2 tanks
The "flammable and combustible" class includes compounds that are: correct answers
Flammable
Pyrophoric (spontaneously ignites when exposed to water or air)
Self-reactive
Self heating
Organic Peroxides
What are risks of flammable and combustible compounds? correct answers - fire hazard, may
burn if ignited
- may ignite spontaneously (under adverse conditions)
- could ignite upon mixing with other chemicals or water
- many are poisonous
What are precautions that should be taken with flammable and combustible materials? correct
answers - avoid contact with flames or other ignition sources
- avoid heat (to minimize evaporation and unexpected ignition)
- cap tightly for storage to minimize aerosols
- avoid inhalation and skin contact
Where should flammables and combustibles be stored in the lab? correct answers in the yellow
flammable cabinet
How should flammables and combustibles be transported? correct answers - securely! no spillage
- separate from oxidizing agents that can act as a source of O2
Name 4 flammable materials: correct answers alcohols, gasoline, ether, acetone
Name 5 Pyrophorics: correct answers - Na, K, Cs, Al, or Zn dust
- metal or alkyl metal hydrides
- metal carbonyls
- gases arsine or silane
- silicon halides
Name 3 self-reacting compounds: correct answers acetylides, ozides, organic nitrates
Name 2 self-heating compounds: correct answers Mg or Na ethoxide, K methoxide
Why are organic peroxides so hazardous? correct answers More shock sensitive than TNT or
piric acid crystals
, What are risks of oxidizing material? correct answers - increase fire and explosion hazard of
flammables when combined
- potentially explosive when mixed with flammables or organics
- many are corrosive and poisonous
What is a precaution that should be taken when working with oxidizing materials? correct
answers - wear protective clothing, avoid personal contact (especially eyes)
What are 2 precautions that should be taken whens storing oxidizing material? correct answers -
store away from combustibles and organics and avoid heating
- store in non-corroding containers, no cork or rubber stoppers
Transport oxidizing materials separately from _____________ and securely to avoid _________.
correct answers flammables, spills
What are some examples of oxidizing material? correct answers Any oxygen source: O2 gas,
peroxides, nitrates/ites, chlorates/ites, hypochlorites (bleach), perchlorates, dichromates,
permanganates, persulfates
______________________ has an immediate toxic effect, while ______________________ has
a delayed toxic effect. correct answers "acute toxic causing death"
"acute toxic causing harm"
The biohazardous infectious material symbol means that: correct answers being exposed to the
material has a negative health affect, possibly lethal
Risks of "acute toxic causing death" correct answers - harmful in small amounts
- may be toxic if ingested, inhaled, or absorbed through eyes or skin
- many are carcinogenic at low levels (minor exposure can be dangerous)
Risks of "acute toxic causing harm" correct answers -systematic damage with low level repeated
exposure
including: permanent injury or death, birth defects in pregnant women
What risks are there to genetically predisposed people working with "acute toxic causing harm"
chemicals? correct answers - activation of cancer formation
- sensitization to allergies
What are the risks of being exposed to biohazardous material? correct answers -systematic
damage with accidental or prolonged exposure
Including:
-acquiring disease and infections (HIV, Hepatitis, rabies, salmonella)
- activation of cancer formation/allergy sensitivities in genetically predisposed people
