CEH Chemical Handling and Safety 3 — Questions and Answers
Question 1: Under OSHA's Hazard Communication Standard (HazCom), who is responsible for ensuring SDSs are accessible to employees?
- The chemical manufacturer only
- The employee who uses the chemical
- The employer (Correct answer)
- The local fire department
Correct answer: The employer
OSHA's HazCom Standard requires employers to maintain SDSs for all hazardous chemicals in the workplace and make them accessible to employees at all times.
Question 2: What is the correct procedure when a chemical splashes into an employee's eyes?
- Apply a neutralizing solution immediately
- Flush eyes with water for at least 15 minutes and seek medical attention (Correct answer)
- Wipe eyes with a clean cloth and monitor for irritation
- Apply eye drops and continue working if discomfort subsides
Correct answer: Flush eyes with water for at least 15 minutes and seek medical attention
Immediately flushing eyes with clean water for at least 15 minutes dilutes and removes the chemical, and medical attention is always required afterward.
Question 3: Which type of chemical cleaner is BEST suited for removing hard water mineral deposits?
- Alkaline-based cleaners
- Acid-based cleaners (Correct answer)
- Neutral pH cleaners
- Enzyme-based cleaners
Correct answer: Acid-based cleaners
Acid-based cleaners dissolve mineral deposits such as calcium and lime scale because the acid reacts with the alkaline minerals to break them down.
Question 4: A housekeeping staff member experiences dizziness and nausea while cleaning a bathroom. What is the most likely cause?
- Overexertion from physical labor
- Inadequate ventilation and chemical fume inhalation (Correct answer)
- Dehydration from working in a warm environment
- An allergic reaction to dust
Correct answer: Inadequate ventilation and chemical fume inhalation
Dizziness and nausea in an enclosed space like a bathroom during chemical use typically indicates insufficient ventilation leading to fume accumulation.
Question 5: What information is REQUIRED on a secondary container label when transferring a chemical from its original container?
- The date of transfer and employee name only
- Product name and hazard warnings (Correct answer)
- The original container's lot number
- The chemical formula and molecular weight
Correct answer: Product name and hazard warnings
OSHA requires secondary containers to be labeled with the product name and appropriate hazard warnings so workers understand the chemical's dangers.
Question 6: What is the purpose of using color-coded spray bottles in housekeeping operations?
- To make the workspace more visually appealing
- To prevent cross-contamination between different cleaning areas (Correct answer)
- To help identify chemical concentration levels
- To comply with fire safety regulations
Correct answer: To prevent cross-contamination between different cleaning areas
Color-coded spray bottles prevent cross-contamination by ensuring chemicals designated for specific areas (e.g., restrooms vs. kitchens) are not accidentally used elsewhere.
Question 7: Which of the following is a key principle of 'green' or environmentally preferable chemical purchasing?
- Selecting products with the lowest cost per ounce
- Choosing concentrated products that minimize packaging waste (Correct answer)
- Purchasing chemicals with the strongest active ingredient percentages
- Selecting chemicals with the longest shelf life
Correct answer: Choosing concentrated products that minimize packaging waste
Concentrated products reduce packaging waste and transportation impacts while often being more cost-effective, aligning with green purchasing principles.
