Section 1: Industrial Cleaning Safety and Hazard Recognition
1. What is the primary purpose of a Job Hazard Analysis (JHA) before
beginning an industrial cleaning task?
A. To estimate the project's final cost
B. To determine the number of workers required
C. To identify potential hazards and establish controls before work
begins
D. To eliminate the need for personal protective equipment
Rationale: A Job Hazard Analysis systematically identifies task-specific
hazards, evaluates the associated risks, and establishes appropriate
controls. It helps workers understand the hazards they may encounter
,and the precautions required to prevent injuries, exposures, and
equipment damage.
2. Which document provides information about a chemical's hazards,
handling, storage, and emergency procedures?
A. Daily production report
B. Equipment maintenance log
C. Confined-space entry permit
D. Safety Data Sheet (SDS)
Rationale: A Safety Data Sheet provides standardized information
about a hazardous chemical, including its properties, health hazards,
required protective equipment, safe handling practices, storage
requirements, and emergency response measures. Workers should
review the SDS before using unfamiliar or hazardous cleaning
chemicals.
3. What should a worker do before entering a permit-required
confined space for industrial cleaning?
A. Enter quickly to minimize exposure time
B. Obtain authorization, evaluate atmospheric hazards, and follow the
confined-space entry procedure
,C. Rely on a coworker to monitor conditions from a distance without
communication
D. Wear a dust mask regardless of the hazards
Rationale: Permit-required confined-space entry requires an
established procedure that addresses atmospheric testing, isolation of
hazards, ventilation when necessary, communication, attendant
responsibilities, and rescue arrangements. Entry must not begin until
the required authorization and safety conditions are established.
4. Which condition is most likely to create an immediate atmospheric
hazard inside a tank?
A. A clean, dry floor
B. Properly functioning lighting
C. An oxygen-deficient atmosphere
D. A recently inspected access ladder
Rationale: Oxygen deficiency can cause impaired judgment, loss of
coordination, unconsciousness, and death. Tanks may contain
displaced oxygen, oxygen-consuming substances, or hazardous gases.
Atmospheric testing must be performed using suitable equipment
before and during entry as required by the entry procedure.
, 5. What is the main purpose of lockout/tagout (LOTO) during
industrial equipment cleaning?
A. To prevent workers from using cleaning supplies
B. To document the number of workers on a shift
C. To identify the equipment manufacturer
D. To prevent unexpected energization or release of hazardous energy
Rationale: Lockout/tagout protects workers from hazardous energy
sources such as electricity, mechanical movement, hydraulic pressure,
pneumatic pressure, and stored energy. Equipment must be properly
isolated, locked or tagged as required, and verified to be in a safe
condition before cleaning begins.
6. Which control is generally preferred when reducing worker
exposure to airborne chemical contaminants?
A. Providing workers with shorter breaks
B. Using effective engineering controls, such as local exhaust
ventilation
C. Increasing the number of workers in the contaminated area
D. Relying exclusively on warning signs
