HCT Chemical Safety & SDS Knowledge 2 — Questions and Answers
Question 1: What is the correct way to dispose of leftover diluted cleaning solution at the end of a job?
- Pour it into any outdoor drain
- Follow local regulations and the product's SDS; most diluted solutions can be safely poured down a utility sink drain (Correct answer)
- Leave it in the client's home for later use
- Mix it with other leftover chemicals to create a concentrated batch
Correct answer: Follow local regulations and the product's SDS; most diluted solutions can be safely poured down a utility sink drain
Proper disposal follows the SDS and local regulations; most diluted consumer cleaners are safe for utility drains but concentrated or hazardous products require special handling.
Question 2: Which GHS (Globally Harmonized System) pictogram indicates that a chemical is flammable?
- A skull and crossbones
- A flame symbol (Correct answer)
- An exclamation mark
- A test tube with droplets
Correct answer: A flame symbol
The GHS flame pictogram identifies flammable liquids, solids, gases, and aerosols that can ignite easily.
Question 3: Why should cleaning chemicals never be stored in unlabeled containers?
- Unlabeled containers are less durable
- Without labels, chemicals can be mistakenly used incorrectly or mixed dangerously (Correct answer)
- Regulatory agencies prefer labeled containers for aesthetic reasons
- Unlabeled containers leak more frequently
Correct answer: Without labels, chemicals can be mistakenly used incorrectly or mixed dangerously
Unlabeled containers lead to accidental misidentification, incorrect use, or dangerous mixing, all of which create serious safety hazards.
Question 4: What does the term 'pH' measure in the context of cleaning products?
- The product's fragrance level
- The acidity or alkalinity of the product, which determines its cleaning action (Correct answer)
- The product's viscosity
- The product's color intensity
Correct answer: The acidity or alkalinity of the product, which determines its cleaning action
pH indicates whether a cleaner is acidic (effective on mineral deposits) or alkaline (effective on grease and oils), guiding product selection.
Question 5: A technician accidentally inhales fumes from a strong chemical cleaner. The immediate action should be to:
- Continue working and wait for the feeling to pass
- Move to fresh air immediately and seek medical attention if symptoms persist (Correct answer)
- Drink water to neutralize the fumes
- Apply moisturizer to the face
Correct answer: Move to fresh air immediately and seek medical attention if symptoms persist
Fresh air removes the source of exposure, and medical evaluation ensures no internal damage from toxic fume inhalation.
Question 6: What is the purpose of a Secondary Container Label when transferring cleaning products from original packaging?
- To decorate the container
- To maintain hazard identification and usage instructions when chemicals are moved to different containers (Correct answer)
- To track inventory levels
- To indicate the price of the product
Correct answer: To maintain hazard identification and usage instructions when chemicals are moved to different containers
Secondary labels ensure that all safety and usage information travels with the product regardless of what container it is placed in.
