At the end of each shift and/or task
100
What label must be on all chemical containers?
The product name and hazard information
100
What does occupational exposure banding aim to determine in a workplace setting?
The potential health risk of chemical exposure when no official exposure limit exists
100
What item must be worn to cover hair during lab gowning?
A bouffant cap or hairnet
100
Do or Don't: Overfill waste container inside the fume hoods
Don't
200
Absorption can enter your body through which two ways?
Chemicals (ex. dust, smoke or vapours) can enter your body through your skin or eyes
200
Daily Double 🙌: What does it mean to "Own It" when it comes to hazards?
"Own It" means taking personal responsibility for safety, both your own and that of those around you, by correcting a hazard, speaking up, or submitting a MySafe observation.
200
What should be done with tools and equipment after use?
Clean and return them to their designated place
200
What is the first step before disposing of any solvent waste?
Identifying the solvent and checking its Safety Data Sheet (SDS)
200
How are occupational bands assigned to chemicals?
By evaluating toxicological data and health effects using a tiered assessment process
200
True or False: Double gloving is allowed when walking through hallways?
False
200
True or False: Hands must be washed with soap and water immediately after working with chemicals, even if gloves are worn
True
300
What is ingestion in terms of chemical exposure?
Ingestion is the term for exposure that happens when a person eats or drinks contaminated substances through the mouth
300
What was the activity we asked that you do during the week "Share It"?
We asked everyone to take a few minutes to share a safety story, lesson, experience, or insight with a coworker.
300
What is the risk of leaving spills or debris on the floor?
The risk is slips, trips and falls
300
What type of container should be used for collecting solvent waste?
A properly labeled, compatible, and sealed waste container
300
This Boundless development trial compound, BOS2, has an Occupational Exposure Limit (OEL) of 5 µg/m³. What band is it?
Band 4
300
What should you do if your gowning garment becomes torn or contaminated during work?
Exit the lab, remove the garment safely, and replace it with a clean one following gowning procedures
300
Daily Double 🙌: Name 2 things wrong with this picture:
The bottle is not labeled properly and has been left completely opened.
400
What is the least common but most direct route of entry for hazardous substances?
Injection (ex. through puncture wounds)
400
Which week was associated with hazard recognition?
The first week which was "See It"
400
Why should you always close the sash on a fume hood when not actively working in it?
To minimize contamination risk and conserve energy by maintaining proper airflow.
400
What are the environmental consequences of improper solvent waste disposal?
Soil and water contamination, harm to wildlife, and long-term ecosystem damage
400
This Concert commercial product, used in the treatment of alopecia, has an Occupational Exposure Limit (OEL) of 52 µg/m³. What band is it?
Band 3
400
Daily Double 🙌: What are the required PPEs you must wear prior to handling any Band 4 solutions & finished products?
10x respiratory protection, double gloves, safety shoes, safety glasses, and disposable coveralls with booties (Tyvek)
400
What is the minimum safe working distance from the front edge of the fume hood?
6 inches
500
Why is it important to understand all routes of entry when assessing chemical hazards?
To implement proper controls and PPE to prevent exposure through any possible pathway
500
What was the main message that was conveyed during the last week "Sustain It"?
"Sustain It" was about embedding the safety behaviours seen throughout July into how we work everyday, not because we're told to, but because it reflects who we are individually and as a team.
500
What are some of the long-term risks that can result from neglecting routine housekeeping in the labs?
Increased fire hazards, chemical incompatibility reactions, reduced productivity, and increased injury risks due to clutter and poor visibility
500
What should you do if you accidentally mix incompatible solvent wastes in the same container?
Stop using the container, report it immediately, and follow hazardous waste incident protocol
500
Daily Double 🙌: What band is EXC in and based on that, what are some examples of engineering controls in place for it?
EXC is Band 4. Examples of engineering controls are the split butterfly valve (SBV), continuous liner system, flexible containment, rapid transfer ports, isolator with glove box, and ventilated balance enclosure (VBE)
500
What are the required PPEs you must wear prior to handling any Band 4 powders?
Double bib PAPR with HEPA cartridges, sleeve covers (or wrist protection), double gloves, safety shoes, and disposable coveralls with booties (ex Tyvek)
500
What is wrong with this picture?
An overcrowded fume hood reduces airflow and increases risk of fire, spill, and cross contamination.
