What is a hazard in a laboratory setting?
A hazard is an essential tool used in experiments.
A hazard is a guaranteed source of safety in a laboratory.
A hazard refers to the cleanliness of the laboratory.
A hazard is a potential source of harm in a laboratory.
Name three common types of hazards found in labs.
Radiation hazards
Ergonomic hazards
Electrical hazards
Chemical hazards, biological hazards, physical hazards
Why is it important to identify hazards in a lab?
To make the lab more visually appealing.
To increase the complexity of experiments.
To ensure all materials are used effectively.
It is important to identify hazards in a lab to ensure safety and prevent accidents.
What should you do if you spill a chemical in the lab?
Alert supervisor, refer to MSDS, use PPE, follow cleanup protocol.
Pour water on the spill to dilute it
Ignore the spill and continue working
Leave the lab immediately without reporting
How can you protect yourself from biological hazards?
Practice good hygiene, use PPE, ensure proper food handling, get vaccinated, and stay informed.
Rely solely on antibiotics
Ignore safety protocols
Avoid all contact with people
What personal protective equipment (PPE) is essential in a lab?
Sunglasses, flip-flops, tank tops
Safety goggles, lab coats, gloves, closed-toe shoes
Earplugs, shorts, baseball caps
Face masks, aprons, sandals
What is the purpose of a safety data sheet (SDS)?
To list the ingredients of a chemical product.
To provide marketing information about a chemical.
The purpose of a safety data sheet (SDS) is to provide information about the hazards of a chemical and how to safely handle, store, and respond to emergencies involving that chemical.
To serve as a user manual for chemical equipment.
How should you store chemicals in the lab?
Store chemicals in unmarked containers on the floor.
Keep all chemicals in direct sunlight for easy access.
Mix all chemicals together in a single container for convenience.
Store chemicals in labeled, compatible containers in a cool, ventilated area, organized by hazard class.
What is the first step to take in case of a fire in the lab?
Continue working as if nothing is wrong.
Leave the lab without informing anyone.
Try to extinguish the fire yourself immediately.
Activate the fire alarm and alert others.
Why is it important to label all containers in the lab?
It is important to label all containers in the lab to ensure safety, prevent accidents, and facilitate proper handling of materials.
Labeling is unnecessary for all containers.
Containers should be labeled only if they are full.
Labels are only needed for hazardous materials.
What are the risks associated with using glassware in experiments?
Glassware can enhance chemical reactions without risks.
Using glassware eliminates the need for safety equipment.
The risks associated with using glassware in experiments include breakage, chemical reactions, thermal shock, and improper handling.
Glassware is indestructible and safe to use.
How can you minimise the risk of slips and trips in the lab?
Use high-gloss floor finishes
Keep floors clean and dry, use non-slip mats, maintain clear walkways, secure loose cables, and ensure proper lighting.
Encourage running in the lab
Ignore spills and clutter
What should you do if you notice a colleague behaving unsafely?
Ignore the behavior and mind your own business.
Confront the colleague aggressively in front of others.
Wait for someone else to address the issue.
Address the colleague directly and report to a supervisor if necessary.
What is the role of a risk assessment in laboratory work?
The role of a risk assessment in laboratory work is to identify and mitigate potential hazards to ensure safety and compliance.
To increase the number of experiments conducted in the lab.
To ensure all lab personnel are trained in data analysis.
To provide a checklist for lab equipment maintenance.
How can you ensure that your workspace is safe before starting an experiment?
Work in a cluttered and disorganized space
Check ventilation, equipment condition, safety gear, workspace cleanliness, and review safety protocols.
Ignore safety gear and start immediately
Use any random chemicals available
