NFPA Incident Safety Officer Certification flashcards

32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Incident Safety Officer

Command staff member designated by the Incident Commander to monitor and assess hazards, recommend safety measures, and stop imminently dangerous operations.

ISO stop authority

The ISO may alter, suspend, or terminate operations judged imminently dangerous, bypassing the chain of command and notifying the Incident Commander as soon as practicable.

Health and Safety Officer

Administrative position under NFPA 1521 responsible for department safety policy, records, training, and post-incident functions rather than scene safety monitoring.

Command staff distinction

The ISO is command staff reporting to the Incident Commander and has no direct supervisory authority over operating companies unless that authority is delegated.

OSHA two-in/two-out

29 CFR 1910.134 requires at least two members inside an IDLH atmosphere in contact with at least two equipped and ready members outside.

NFPA 1500 scope

Standard on fire department occupational safety, health, and wellness programs, requiring an incident management system and a designated safety officer function.

NFPA 1521 scope

Standard defining professional qualifications for the incident safety officer and health and safety officer and the tasks each must be able to perform.

Standard of care

The level of care established by statute, adopted standards, department policy, and prior practice; deviation from a recognized standard may be evidence of negligence.

Risk-benefit decision rule

Activities are undertaken only when the potential benefit outweighs the risk; no property is worth a member's life and no risk without realistic benefit.

Hierarchy of controls

Order of effectiveness from most to least: elimination, substitution, engineering controls, administrative controls, and personal protective equipment.

Residual risk

The risk remaining after controls are applied; the ISO documents and communicates it to the Incident Commander before operations proceed.

Risk management process

Five steps: identify hazards, evaluate risks, prioritize risks, implement controls, and monitor and reassess throughout the incident.

Safety message in IAP

Portion of the Incident Action Plan identifying known hazards, required control measures, and PPE requirements communicated to all assigned personnel.

Written IAP trigger

An incident extending beyond one operational period requires a written Incident Action Plan that the ISO reviews for safety integration.

Declined safety recommendation

When the Incident Commander declines an ISO recommendation, the ISO documents the concern, the time, and the decision made.

Collapse zone perimeter

Exclusion area around a structure set at one and a half times the wall height to protect members from falling walls and debris.

Collapse indicators

Visible sagging, cracking, spalling, smoke or water through cracks, and prolonged heavy fire involvement, any of which triggers evacuation.

Fire behavior indicators

Neutral plane, smoke color and velocity, heat, and flame volume; rapid changes require reassessment of interior operations by the ISO.

Rapid intervention team

Staffed and equipped rescue team established before interior operations begin, with a charged hoseline, ladders, forcible entry tools, search rope, and thermal imager.

Personnel accountability report

A PAR is conducted at defined benchmarks such as strategy change, emergency evacuation, and every 10 to 20 minutes during extended operations.

Mayday transmission content

Report of unit, member name, location, and nature of the problem; the ISO confirms acknowledgment and the shift to rescue mode.

Air management rule

Members must exit the IDLH atmosphere before the low-air alarm activates; the ISO tracks interior crew working time against air supply.

ISO incident log

Written record kept during the incident noting time, observation, action taken, and notification of the Incident Commander.

360-degree assessment

Periodic walk-around of the incident scene by the ISO to re-evaluate the building, exposures, and operating positions as conditions change.

Rehabilitation trigger

Rest, rehydration, and medical monitoring established after 20 to 30 minutes of strenuous work or one SCBA cylinder, or in extreme weather.

NFPA 1584 scope

Standard on rehabilitation during emergency operations, covering rest, rehydration, nourishment, medical monitoring, and temperature regulation for members.

Post-incident analysis

Structured review after a significant incident examining strategy, tactics, safety, and outcomes to identify contributing factors and corrective actions.

NFPA 921 role

Provides methodology for fire and explosion investigation; the safety officer supports scene safety and evidence preservation, not origin and cause determination.

Confined space entry requirements

Under 29 CFR 1910.146, entry requires atmospheric monitoring, ventilation, an attendant, and a rescue plan before any member enters.

Trench spoil pile setback

Spoil and equipment are set back at least the depth of the trench to prevent collapse loading; shoring or shielding is required before entry.

Rope rescue safety check

Before a load is applied, the safety officer verifies anchor integrity, system redundancy, and a belay or backup system.

Hazmat site safety plan

Written plan required under OSHA HAZWOPER covering PPE levels, decontamination, medical monitoring, and zone control for entry teams.
