Mixed Deck — All WPR Topics Flashcards

What does the term 'permit isolation' refer to in safety communication?

Answer: Physically isolating energy sources and communicating those isolations clearly on the permit

Permit isolation involves LOTO or other energy control measures and requires that all isolations are documented and communicated on the permit form.

Fit testing for tight-fitting respirators is required by OSHA:

Answer: Initially before first use and annually thereafter, or when physical changes may affect fit

OSHA 29 CFR 1910.134 requires initial and annual fit testing for all tight-fitting respirators to ensure an adequate seal.

How often should a Work Permit Receiver perform monitoring checks on an active worksite?

Answer: Periodically throughout the work process

A Work Permit Receiver should perform monitoring checks periodically throughout the work process, not just at the start. Continuous monitoring ensures that safety conditions remain stable, new hazards are identified, and workers continue to adhere to safety protocols as the work progresses. The frequency may vary depending on the nature and duration of the work, but regular checks are essential for sustained safety.

Which of the following is a physical hazard that a Work Permit Receiver should look for during site assessment?

Answer: Slippery floors

During a site assessment, a Work Permit Receiver should actively look for various physical hazards that could cause harm. Examples include slippery floors, which can lead to slips, trips, and falls, and electrical wiring without proper insulation, posing a risk of electric shock or fire. Identifying and addressing these physical dangers is essential for maintaining a safe work environment.

Safety data sheets (SDS) Section 8 provides:

Answer: Exposure limits and recommended PPE for handling the chemical

SDS Section 8 (Exposure Controls/Personal Protection) specifies occupational exposure limits and the appropriate PPE for handling the specific chemical.

The scope of a hot work permit explicitly states 'grinding only.' During the job, the crew decides to also weld. What must happen?

Answer: Work must stop and a new or amended permit must be obtained that specifically authorizes welding

Welding is a different task with different hazards than grinding; the original permit's scope does not cover it and a new authorization is required.

What must a WPR verify before accepting a work permit?

Answer: That all required signatures and conditions on the permit are complete and accurate

The WPR must confirm that all required authorizations, conditions, and signatures are present before accepting the permit.

What does 'PASS' stand for in fire extinguisher operation?

Answer: Pull, Aim, Squeeze, Sweep

PASS (Pull, Aim, Squeeze, Sweep) is the standard four-step technique for operating a portable fire extinguisher.

What ANSI/ISEA standard governs high-visibility safety apparel used in US work sites?

Answer: ANSI/ISEA 107

ANSI/ISEA 107 specifies performance requirements for high-visibility safety apparel including vests, jackets, and coveralls.

Which of the following should be included in the records kept by a Work Permit Receiver?

Answer: Copies of issued work permits

A Work Permit Receiver is responsible for managing and overseeing work permits, which are critical safety documents. Keeping copies of issued work permits is essential for maintaining a clear audit trail and demonstrating compliance with safety procedures. This documentation ensures accountability and provides vital information for future reviews or investigations.

What type of hazard does working in a confined space present, and what should the Work Permit Receiver check for?

Answer: Chemical hazard; air quality testing

Working in a confined space presents significant chemical hazards due to the potential for hazardous atmospheres, such as oxygen deficiency, flammable gases, or toxic fumes. Therefore, a Work Permit Receiver must check for thorough air quality testing before and during entry to ensure the atmosphere is safe. This critical step prevents exposure to dangerous substances and ensures breathable air for workers.

Double hearing protection (earplugs plus earmuffs) is required when noise levels exceed:

Answer: 100 dB(A) or as specified by the site's hearing conservation program

OSHA and most site programs require dual hearing protection when noise levels exceed 100 dB(A) or when single protection is insufficient to reduce exposure to safe levels.

A cold work permit is distinguished from a hot work permit because:

Answer: Cold work does not introduce ignition sources and involves only non-sparking, non-flaming activities

Cold work permits cover non-ignition tasks such as mechanical disassembly, painting with non-flammable materials, or structural inspections.

Which of the following best describes a non-routine work permit?

Answer: A permit required for infrequent or high-hazard tasks outside normal operational procedures

Non-routine permits address activities outside standard operating procedures where hazards may be unique or elevated.

An assembly point (muster area) is important because:

Answer: It provides a safe, pre-designated location where all evacuated personnel can be accounted for

Assembly points allow headcounts to determine if anyone is missing, enabling targeted rescue without unnecessary entry into dangerous areas.

A WPR should conduct a pre-work safety briefing:

Answer: Before each shift and whenever crew members change or conditions are updated

Each shift brings potential new hazards and personnel changes; daily briefings ensure everyone is aligned on current conditions and controls.

When work is suspended due to an emergency, who controls re-entry to the permitted work area?

Answer: The permit issuer in coordination with the safety officer and emergency response authority

Re-entry after an emergency requires a multi-party decision to confirm the hazard is resolved and controls are in place.

As a Work Permit Receiver, what must you verify BEFORE allowing work to begin under a LOTO-related permit?

Answer: That all energy isolation devices are properly locked and/or tagged out

The Work Permit Receiver must confirm that all energy isolation points are locked and/or tagged out before authorizing work to begin, ensuring zero-energy state.

What action should a Work Permit Receiver take if a work permit has missing information before storing it in the records?

Answer: Send it back for correction

A work permit is a critical document that authorizes specific work under controlled conditions, ensuring safety and compliance. If it has missing information, it is incomplete and potentially invalid, compromising its purpose. The Work Permit Receiver must ensure all permits are fully and accurately completed before filing, so sending it back for correction is the appropriate step to maintain record integrity and operational safety.

When a gas detector alarm sounds during hot work, the WPR must:

Answer: Immediately cease all hot work, remove ignition sources, and evacuate the area

A gas detector alarm during hot work signals an imminent explosion or fire risk, requiring immediate halt of all ignition activities and evacuation.
