Mixed Deck — All ASP Topics Flashcards

What is the PRIMARY purpose of a pre-task safety briefing (toolbox talk)?

Answer: To review hazards and controls relevant to that day's specific work

Pre-task briefings focus workers on current, site-specific hazards immediately before work begins, making them highly relevant and timely.

During a job hazard analysis (JHA), a safety professional breaks a task into discrete steps. What is the PRIMARY reason for this approach?

Answer: To identify specific hazards associated with each step and develop targeted controls

Breaking tasks into steps allows the analyst to pinpoint exactly where and how hazards arise, enabling precise control measures for each step.

What is the minimum required separation between incompatible hazardous waste containers in storage?

Answer: 3 feet or a physical barrier

Incompatible hazardous wastes must be separated by at least 3 feet or a physical barrier to prevent dangerous chemical reactions.

A company performs a bow-tie analysis. What does the LEFT side of the bow-tie diagram represent?

Answer: Threats and prevention barriers leading to the top event

The left side of the bow-tie depicts threats (causes) and the preventive barriers that stop them from causing the central hazardous event.

What is the purpose of OSHA's Hazard Communication Standard (HazCom)?

Answer: To ensure information about chemical hazards is communicated through labels, SDSs, and training

HazCom ensures workers are informed about chemical hazards through a comprehensive program of labels, Safety Data Sheets, and training.

Under OSHA 29 CFR 1910.333, a 'qualified worker' performing electrical work must demonstrate which of the following?

Answer: Ability to avoid hazards of working on or near exposed energized parts

OSHA defines a qualified person as one who has training and experience to recognize and avoid the electrical hazards present in energized work.

Which document is legally required to accompany hazardous waste during off-site transportation under RCRA?

Answer: Uniform Hazardous Waste Manifest

The Uniform Hazardous Waste Manifest is the tracking document that must accompany all hazardous waste shipments off-site.

The Limited Approach Boundary defined by NFPA 70E is the distance from an energized conductor within which:

Answer: An unqualified person may not cross without being escorted and briefed on electrical hazards

The Limited Approach Boundary is the closest distance an unqualified person may approach unless escorted by a qualified person and aware of the hazards.

Which type of ventilation control is best suited for controlling emissions from a low-toxicity, large-area diffuse source?

Answer: General dilution ventilation

General dilution ventilation dilutes contaminants with clean air across a large area and is cost-effective for low-toxicity diffuse sources.

What is the Kirkpatrick Model used for in safety training?

Answer: To evaluate training effectiveness across four levels: reaction, learning, behavior, and results

The Kirkpatrick Model evaluates training at four levels: reaction, learning, behavior, and results.

According to NFPA 72, what is the required spacing for heat detectors in a standard room with a smooth, flat ceiling?

Answer: 50 feet maximum

NFPA 72 allows heat detectors to be spaced up to 50 feet apart on smooth, flat ceilings under standard conditions.

Under OSHA 1926.503, fall protection training must be provided by:

Answer: A competent person

OSHA 1926.503 requires that fall protection training be conducted by a competent person with knowledge of fall hazards.

A safety professional needs to calculate the dilution ventilation required to control a solvent with an evaporation rate of 1 pint/hour. The solvent has a specific gravity of 0.88 and a molecular weight of 92. The TLV is 100 ppm. Using the standard dilution ventilation formula, approximately how many cubic feet per minute (CFM) of fresh air are needed (using K=10)?

Answer: Approximately 11,300 CFM

The ACGIH dilution formula: Q = (403 × SG × ER × K) / (MW × TLV). Converting 1 pint/hr to cubic feet: 1 pint = 0.01671 ft³. Q = (403 × 0.88 × 1 pint/hr × 10) / (92 × 100 ppm × 10⁻⁶) ≈ 11,300 CFM. This large airflow requirement is why dilution ventilation is impractical for high-toxicity solvents.

An organization adopts a 'just culture' policy. This means the organization will:

Answer: Distinguish between honest mistakes and reckless behavior when responding to errors

Just culture distinguishes between inadvertent human error, at-risk behavior, and reckless behavior to apply proportionate responses and encourage reporting.

Which environmental regulatory program requires facilities to report extremely hazardous substance inventories to local emergency planning committees?

Answer: EPCRA Sections 311-312

EPCRA Sections 311-312 require facilities to submit chemical inventory information to LEPCs, fire departments, and state agencies.

At what fall height must OSHA's construction standard require fall protection for workers on walking/working surfaces?

Answer: 6 feet

OSHA's construction standard (29 CFR 1926.502) requires fall protection when workers are exposed to falls of 6 feet or more.

Under U.S. product liability law, 'strict liability' in a tort claim means:

Answer: A manufacturer can be held liable for injuries caused by a defective product even if they were not negligent

Under strict product liability (established in Restatement Second of Torts §402A), a manufacturer is liable for injuries caused by an unreasonably dangerous defective product regardless of whether they exercised due care. The plaintiff does not need to prove negligence—only that the product was defective and the defect caused harm.

Under OSHA's HazCom standard (29 CFR 1910.1200), what is the primary purpose of a Safety Data Sheet (SDS)?

Answer: Communicate chemical hazard information to workers

SDS documents communicate chemical hazards, safe handling, and emergency response information as required by HazCom 2012.

An SMS internal audit differs from an inspection PRIMARILY in that an audit:

Answer: Systematically evaluates whether SMS elements are implemented and effective

An SMS audit systematically assesses whether management system elements are in place, implemented, and achieving intended results, beyond just physical conditions.

In an SMS, what does the term 'residual risk' refer to?

Answer: Risk remaining after controls have been implemented

Residual risk is the level of risk that remains after all feasible controls have been applied.
