911 Safety Quiz
Questions: 16 · 10 minutes
1. A protective ensemble includes a tight-fitting respirator. What must occur before a worker relies on that respirator?
The worker must choose whichever model feels most comfortable
It must be used within a respiratory-protection program with required evaluation, fit testing, training, and hazard-specific selection
The worker must wear two cartridges to cover any possible contaminant
The worker only needs to check that air can pass through it
2. The outside of a worker’s coverall may be contaminated. Which removal approach best limits transfer to skin and clothing?
Pull it off quickly before the contaminant can penetrate farther
Ask a coworker without PPE to remove it from behind
Use the trained doffing sequence, avoid touching the exterior, and follow decontamination and disposal procedures
Cut through any area that appears visibly contaminated
3. Before entering a controlled work area, what is the most useful final check after putting on protective clothing?
Check the garment’s condition, closures, fit, and interfaces with gloves, boots, or other PPE
Loosen closures so heat can escape during the task
Confirm that the clothing looks similar to what others are wearing
Test the garment by briefly touching it to the hazardous material
4. During a pre-use inspection, you find a tear beside the zipper of a protective coverall. What should you do?
Wear a cotton shirt underneath to restore the barrier
Wear it only for the shortest portion of the task
Cover the tear with any available tape and continue
Remove it from service and replace or address it under the approved procedure
5. A task may send corrosive liquid toward a worker’s eyes and face. Which protection is generally appropriate when the hazard assessment confirms splash risk?
A face shield by itself, because it covers more of the face
Ordinary safety glasses beneath a cloth hood
Chemical-splash goggles with a compatible face shield worn over them
A face shield with small ventilation gaps and no eye protection
6. When calling 911 about a serious workplace exposure, which information is most important to communicate early?
The injured person’s complete employment history
The exact location, nature of the emergency, known hazard, and number and condition of affected people
The brand and purchase date of every garment being worn
Your theory about who caused the incident
7. A pesticide has soaked through a worker’s protective clothing. What is the best way to handle the contaminated garment after emergency decontamination begins?
Isolate it and follow the product label, safety data, and workplace procedure for decontamination or disposal
Hang it in a shared area until the odor disappears
Take it home separately and wash it with extra detergent
Return it to storage if the outside looks dry
8. An electrical task has a documented arc-flash hazard. Which clothing choice addresses that hazard most directly?
Any garment made from thick natural fibers
A standard high-visibility vest over everyday clothing
Arc-rated clothing with a rating and system selected for the assessed exposure
A disposable chemical coverall because it covers the whole body
9. A coworker’s protective sleeve catches fire. What is the best immediate response?
Alert the person, use an emergency shower if immediately available or stop, drop, and roll, then summon emergency help
Pull the burning sleeve off with bare hands
Cover the flames with another worker’s untreated jacket
Tell the person to run to the nearest exit
10. While wearing an impermeable suit, a worker becomes dizzy, weak, and unusually sweaty. What is the best response?
Drink water while continuing, because sweating shows that cooling is working
Open the suit inside the hazardous area and finish the task slowly
Stop the task, reach a safe area, alert others, cool down, and obtain medical help as needed
Wait until the planned break unless the worker loses consciousness
11. Before choosing protective clothing for a task, what should determine the required garment features?
The garment color commonly used in that department
A hazard assessment covering the substance or energy involved, exposure route, task, and duration
Whether the garment is heavier than ordinary work clothing
Whether coworkers have worn the same style without an incident
12. A worker will be close to exposed moving machinery. Which clothing practice best addresses entanglement?
Wear loose sleeves so the arms can move freely
Add a high-visibility vest with hanging adjustment straps
Wear multiple loose layers to create distance from the machinery
Use close-fitting, secured clothing and follow guarding and task-specific procedures
13. What is the main safety function of high-visibility clothing?
Preventing hazardous chemicals from reaching the skin
Making the wearer easier to detect; other hazards require separate protection
Replacing barriers and traffic-control procedures
Providing insulation against any source of extreme heat
14. What does the word “disposable” mean on a protective coverall?
It is intended for limited use, but only protects against hazards and conditions specified by its documentation
It protects against every hazard for one complete shift
It can be reused whenever no contamination is visible
It requires no inspection because it will eventually be discarded
15. A coworker collapses inside an area where an unknown vapor may be present. You have no rescue training or suitable protective equipment. What should you do?
Wait for the vapor to become visible before deciding whether to call
Hold your breath, enter quickly, and drag the person out
Put on a disposable coverall and enter without respiratory protection
Stay out, move to a safe location, call 911, report the possible vapor hazard, and wait for trained responders
16. Two gloves are equally thick, but only one is listed as compatible with the solvent being handled. Which should be selected?
The softer glove, because flexibility indicates better protection
Both gloves layered together, regardless of their materials
Either glove, because equal thickness means equal chemical resistance
The compatible glove, based on manufacturer data such as permeation and degradation
