CEH Chemical Handling and Safety 5 — Questions and Answers
Question 1: Under what circumstance should a housekeeping chemical NEVER be used?
- When the original container label is faded or missing (Correct answer)
- When the chemical is more than six months old
- When the product has not been used in over a week
- When outdoor temperatures exceed 90°F
Correct answer: When the original container label is faded or missing
A chemical should never be used if its label is missing or unreadable, as the label contains critical safety, usage, and hazard information required for safe handling.
Question 2: Which of the following best describes a 'flammable' chemical according to GHS classification?
- A chemical with a flash point above 140°F (60°C)
- A liquid with a flash point at or below 140°F (60°C) (Correct answer)
- Any chemical that burns when exposed to an open flame
- A chemical that explodes when mixed with water
Correct answer: A liquid with a flash point at or below 140°F (60°C)
GHS classifies flammable liquids as those with a flash point at or below 60°C (140°F), meaning they can ignite at or near room temperature.
Question 3: What action should be taken if a chemical spill occurs on a hard floor in a guest corridor?
- Mop the spill immediately with any available mop
- Secure the area, don appropriate PPE, and follow the SDS spill procedures (Correct answer)
- Dilute the spill with large amounts of water and walk away
- Wait for a supervisor before taking any action
Correct answer: Secure the area, don appropriate PPE, and follow the SDS spill procedures
Securing the area protects guests and staff, PPE protects the responder, and SDS procedures ensure the spill is handled correctly and safely.
Question 4: What is the significance of a chemical's 'Threshold Limit Value' (TLV)?
- The maximum amount of chemical that can be stored on-site
- The airborne concentration level at which most workers can be exposed without harmful effects (Correct answer)
- The minimum effective concentration for disinfection
- The temperature at which a chemical becomes hazardous
Correct answer: The airborne concentration level at which most workers can be exposed without harmful effects
TLV represents the airborne concentration of a chemical to which nearly all workers may be repeatedly exposed without experiencing adverse health effects.
Question 5: A housekeeper is pregnant and concerned about chemical exposure. What is the BEST course of action for the executive housekeeper?
- Reassure her that all approved chemicals are completely safe
- Review chemical SDSs for reproductive hazards and consult HR and occupational health (Correct answer)
- Immediately remove her from all housekeeping duties
- Have her sign a waiver and continue normal duties
Correct answer: Review chemical SDSs for reproductive hazards and consult HR and occupational health
Reviewing SDSs for reproductive toxicity data and consulting HR and occupational health ensures the employee's health is protected while following legal and ethical obligations.
Question 6: Which of the following chemical storage practices helps prevent accidental ingestion by guests or children?
- Storing chemicals in attractive, brightly colored containers
- Keeping all chemicals in locked storage areas inaccessible to unauthorized persons (Correct answer)
- Labeling chemical containers with large warning symbols only
- Storing chemicals in guest room cleaning carts at all times
Correct answer: Keeping all chemicals in locked storage areas inaccessible to unauthorized persons
Locked storage prevents unauthorized access, which is the primary safeguard against accidental ingestion or misuse of cleaning chemicals.
Question 7: What is the role of an executive housekeeper in chemical safety program management?
- To select the least expensive chemicals available on the market
- To ensure training, proper storage, SDS availability, and regulatory compliance across the department (Correct answer)
- To personally handle all chemical spill cleanup to protect staff
- To delegate all chemical safety responsibilities to frontline staff
Correct answer: To ensure training, proper storage, SDS availability, and regulatory compliance across the department
The executive housekeeper is responsible for overseeing the entire chemical safety program, including training, compliance, storage protocols, and maintaining required documentation.
