Industrial Cleaner Level I | Verified Q&A | Pass
Guaranteed - A+ Graded
Section 1: Safety & Personal Protective Equipment (Questions 1–12)
Q1: An industrial cleaner is assigned to degrease a concrete floor area near an active electrical panel
using a high-alkaline detergent solution. Which minimum PPE is required according to OSHA 1910.132
for this task?
A. Leather gloves and steel-toe boots only
B. Safety glasses and cloth work gloves
C. Chemical-resistant gloves, goggles, and rubber boots
D. Face shield only over bare hands
Correct Answer: C
Rationale: Alkaline degreasers are corrosive to skin and eyes; chemical-resistant gloves (nitrile or
neoprene), chemical splash goggles, and rubber boots provide barrier protection from splashes and floor
contact, per OSHA hazard assessment requirements. [CORRECT]
Q2: A worker finds an unlabeled spray bottle containing a clear liquid in the industrial cleaning supply
closet. What is the correct first action?
A. Smell the liquid to help identify it
B. Dispose of it in the regular trash
C. Use a small amount on a test surface
D. Tag it as unlabeled and notify the supervisor
Correct Answer: D
Rationale: Unlabeled chemicals present unknown hazards; tagging the container and immediately
notifying a supervisor ensures proper identification, labeling, or disposal per hazard communication
standards. [CORRECT]
,Q3: A cleaner is preparing to enter a confined space (a storage tank) that previously held solvent
residues. The atmosphere has been tested and shows 18.5% oxygen. What is the required respiratory
protection?
A. No respiratory protection needed
B. Half-mask respirator with organic vapor cartridges
C. Supplied-air respirator or SCBA
D. N95 disposable dust mask
Correct Answer: C
Rationale: Oxygen levels below 19.5% constitute an oxygen-deficient atmosphere per OSHA 1910.146;
supplied-air respirators or SCBAs are mandatory for entry into immediately dangerous to life or health
(IDLH) conditions. [CORRECT]
Q4: During lockout/tagout (LOTO) procedures before cleaning a conveyor system, which step must be
completed FIRST?
A. Apply personal locks and tags to the energy isolation devices
B. Notify all affected employees that servicing is beginning
C. Shut down the equipment using normal stopping procedures
D. Verify zero energy state with a test start attempt
Correct Answer: C
Rationale: OSHA 1910.147 requires equipment to be shut down using normal stopping procedures as
the initial step in the LOTO sequence before isolation, lock application, and verification. [CORRECT]
Q5: A cleaner is using a pressure washer rated at 3,000 PSI to remove grease from production
equipment. What PPE is specifically required to prevent high-pressure injection injuries?
A. Standard leather work gloves
B. Cut-resistant gloves
C. Heavy-duty chemical-resistant gloves with gauntlet cuffs
D. Leather-palm cotton gloves
Correct Answer: C
Rationale: High-pressure injection injuries occur when pressurized fluid penetrates skin; heavy-duty
chemical-resistant gloves with gauntlet cuffs provide the necessary barrier against both chemical
exposure and high-pressure penetration. [CORRECT]
, Q6: A worker in a food processing plant is cleaning with a chlorine-based sanitizer in an enclosed room
with poor ventilation. The worker experiences coughing and eye irritation. What is the FIRST action?
A. Continue cleaning while holding breath
B. Immediately exit the area to fresh air
C. Open a window and continue working
D. Switch to a different cleaning chemical
Correct Answer: B
Rationale: Chlorine vapors are respiratory irritants; immediate removal to fresh air prevents further
inhalation exposure and potential chemical pneumonitis, per OSHA respiratory protection protocols.
[CORRECT]
Q7: According to OSHA 1910.138, when must hand protection be provided to cleaning personnel?
A. Only when handling acids or caustics
B. When hands are exposed to hazards such as skin absorption, cuts, abrasions, or chemical burns
C. Only during confined space entry
D. Only when using power tools
Correct Answer: B
Rationale: OSHA 1910.138 mandates hand protection when employees' hands are exposed to hazards
including harmful substances, severe cuts, abrasions, punctures, or chemical burns during cleaning
operations. [CORRECT]
Q8: A cleaner is working in a refrigerated facility at 35°F (2°C) for extended periods. Which PPE
combination addresses the primary hazards?
A. Insulated coveralls, thermal gloves, and slip-resistant insulated boots
B. Standard cotton coveralls and leather gloves
C. Rain gear and rubber boots only
D. High-visibility vest and hard hat
Correct Answer: A
Rationale: Cold stress hazards including hypothermia and frostbite require insulated protective clothing;
slip-resistant boots address ice formation, and thermal gloves maintain dexterity while preventing cold-
related tissue damage. [CORRECT]
Q9: A worker needs to clean up broken glass and chemical residue from a dropped container. What is
the correct PPE selection sequence?
