Which common office item is most likely to harbour germs due to frequent hand contact?
Desk surface
Computer keyboard
File cabinet top
Window sill
Computer keyboards accumulate bacteria from frequent typing and hand contact. They are rarely cleaned and can harbour pathogens. This makes them a high-risk surface in offices.
What is the primary purpose of disinfecting a surface after cleaning?
To polish and shine the surface
To remove physical debris only
To kill remaining pathogens on the surface
To deodorize the area
Disinfection targets microorganisms left after cleaning to reduce infection risk. It does not focus on dirt removal or aesthetics. Killing pathogens is the key goal of disinfection.
According to hygiene guidelines, how long should you rub your hands together when washing with soap and water?
5 seconds
20 seconds
10 seconds
30 seconds
Health guidelines recommend at least 20 seconds of scrubbing to effectively remove germs. Shorter times may not break down dirt and microbes. This duration ensures thorough coverage.
Where should used disposable tissues and single-use wipes be disposed in an office setting?
Recycle bin
Lined trash bin
Compost bin
Hazardous waste container
Disposable tissues and wipes contaminated with germs belong in a lined trash bin. Recycling or composting can spread pathogens. Hazardous waste is reserved for chemical or medical waste.
Which office item should be disinfected daily due to its high frequency of hand contact?
Office chair backrest
Monitor screen
Phone handset
Desk legs
Phone handsets are handled frequently and shared among users. This makes them a common vector for germ transmission. Daily disinfection reduces contamination risk.
Which of the following is most effective against a broad spectrum of viruses on office surfaces?
70% isopropyl alcohol
Ionized water
Mild soap solution
Plain water rinse
A 70% isopropyl alcohol solution is widely recommended to inactivate a broad range of viruses. It denatures proteins and disrupts membranes effectively. Other options do not offer the same virucidal activity.
What is the correct sequence when cleaning and disinfecting a workstation?
Disinfect first, then clean with detergent
Clean with detergent, then apply disinfectant
Remove clutter, disinfect, then clean
Dry wipe surfaces, then disinfect
Cleaning with detergent removes dirt and organic matter that can shield microbes. Disinfection is only effective once surfaces are clean. Following this order ensures pathogens are exposed to the disinfectant.
In which situation is it appropriate to use an alcohol-based hand sanitizer instead of soap and water at work?
When hands are not visibly soiled
After a chemical spill
Before handling food
When wearing gloves
Alcohol-based sanitizers are effective when hands appear clean but may not remove visible dirt. Soap and water are required if hands are soiled or after certain exposures. Sanitizer is not a substitute for glove changes.
How often should high-touch surfaces like door handles and elevator buttons be disinfected in a busy office environment?
Once daily
Every 4 hours
Every 48 hours
Only when visibly dirty
High-touch surfaces accumulate germs quickly in busy areas. A 4-hour interval balances practicality and hygiene efficacy. Less frequent cleaning may allow pathogen build-up.
Which factor is most critical when determining the frequency of cleaning for specific office areas?
Available budget
Traffic and usage level
Number of staff in cleaning department
Color of office décor
Areas with higher footfall and usage accumulate contaminants faster. Cleaning frequency should match traffic patterns. Budget and staff numbers affect implementation but not the hygiene requirement.
What is the most effective way to organise shared office supplies to reduce germ transmission?
Keep all supplies in a central communal bowl
Provide individual supply kits for each employee
Store supplies in open shelving
Allow free access for everyone
Individual supply kits limit shared contact points and reduce cross-contamination. Centralized supplies invite frequent touching by multiple users. Organizing per person supports hygiene.
Into which bin should confidential printed documents be placed to ensure safe disposal?
General recycle bin
Secure shred bin
Food waste bin
Hazardous waste container
Confidential documents require secure shredding to prevent information breaches. A shred bin collects paper for secure disposal. Recycling alone does not protect sensitive data.
Which personal protective equipment (PPE) is essential when handling surface disinfectants in the workplace?
Safety goggles
Disposable gloves
Cloth apron
Open sandals
Disposable gloves protect skin from chemical irritation and absorption. Other gear may be needed in specialized settings, but gloves are the baseline. Proper PPE reduces exposure risk.
What tool helps track routine cleaning tasks and ensures that no area is missed?
Cleaning checklist or log
Random inspections only
Employee attendance sheet
Room booking system
A cleaning checklist outlines tasks, frequencies, and responsible persons. It provides accountability and documentation of completed work. Checklists reduce the chance of missed areas.
What is the main advantage of using color-coded cleaning cloths in office hygiene?
They look visually appealing
They prevent cross-contamination between different areas
They reduce cloth costs
They indicate cloth age
Color-coded cloths ensure specific cloths are only used in designated areas. This system prevents germs from spreading between zones. It is a simple but effective cross-contamination control.
What is the proper method for disinfecting a computer keyboard without causing damage?
Spray disinfectant directly onto all keys and let it air dry
Unplug the keyboard, apply disinfectant to a microfiber cloth, then gently wipe surfaces
Submerge the keyboard in a disinfectant solution
Wipe with a dry cloth only
Applying disinfectant to a cloth prevents liquid ingress that can damage electronics. Unplugging ensures no electrical risk. Gentle wiping maintains device integrity while disinfecting.
Which disinfectant commonly used in offices must be thoroughly rinsed after application to prevent corrosion and residue buildup?
Quaternary ammonium compounds
70% isopropyl alcohol
Sodium hypochlorite (bleach) solution
Neutral pH detergent
Bleach (sodium hypochlorite) can corrode metals and leave salts on surfaces if not rinsed. Thorough rinsing removes residues and preserves materials. Other agents typically do not require full rinsing.
In a color-coded cloth system, which color is conventionally designated for restroom cleaning to minimise cross-contamination?
Blue
Green
Red
Yellow
Red is widely used to identify high-risk areas such as restrooms. Using a dedicated color prevents cloths from being used elsewhere. This reduces the chance of spreading pathogens.
An ATP hygiene monitor reading returns 1200 RLUs after cleaning a breakroom table. What does this indicate and what action should be taken?
Acceptable cleaning; continue routine schedule
Low level of residue; reduce detergent use
Poor cleaning efficacy; review procedures and retrain staff
Equipment fault; calibrate monitor only
Readings above 1000 RLUs indicate high organic residue and inadequate cleaning. This requires a review of cleaning protocols and staff retraining. Routine calibration alone will not address the hygiene issue.
What is the correct procedure for disposing of expired concentrated disinfectants in an office environment?
Dilute and pour down the sink
Mix with other cleaning agents and discard
Label original containers and arrange disposal as chemical hazardous waste
Store indefinitely until needed
Expired concentrated disinfectants are regulated as hazardous waste. They must be kept in properly labelled containers for specialized disposal. Improper disposal can harm the environment and violate regulations.
