16.1 Evaluating and Reporting Progress
Key Takeaways
- NFPA 470 (2022) JPR 11.5.1 is evaluate and report assigned tasks: compare actual material and container behavior to what was predicted, decide whether tactics accomplished the strategy, modify tactics, and communicate the results.
- TEEX HAZ020 tests evaluate effectiveness of control functions and of decontamination; a shrinking cloud, a holding dike, or a slowing leak is progress — a static 40 percent LEL after 20 minutes in the same PPE is a failed plan, not a reason to try harder.
- Entry-clock, remaining air, and heat stress are tactical limits equal to the chemical reading; if any of those clocks is about to expire, withdraw, change tactics, or escalate rather than stretching the ensemble.
- Progress reports go up the ICS — Hazmat Group Supervisor, Operations Section Chief, Incident Commander, and Safety — using approved communications; one snapshot is not a trend.
- IAFF APIE-T Evaluate (11.5) is not Terminate (11.6): if objectives are not met, loop back to Analyze/Plan; if they are met and hazards are controlled, then you may terminate.
16.1 Evaluating and Reporting Progress
Quick Answer: National Fire Protection Association (NFPA) 470 (2022) Job Performance Requirement (JPR) 11.5.1 is evaluate and report the progress of assigned tasks at a hazardous materials / weapons of mass destruction (WMD) incident. Compare actual material and container behavior to what you predicted. Decide whether the tactics accomplished the strategy. Modify tactics. Communicate the results on approved equipment. Texas A&M Engineering Extension Service (TEEX) HAZ020 states the same skill in academy English: evaluate effectiveness of control functions and evaluate effectiveness of decon. International Association of Fire Fighters (IAFF) APIE-T puts this letter at Evaluate. It is not Terminate.
Chapter 15.3 built the Incident Action Plan (IAP). This section is the honesty check. A kit on the valve is not proof the leak stopped. A corridor that moved people is not proof they are clean. A four-gas meter that read 40 percent of the lower explosive limit (LEL) twenty minutes ago and still reads 40 percent LEL is not “we need more time in Level A.” It is a failed plan. Occupational Safety and Health Administration (OSHA) 29 CFR 1910.120(q)(6)(iii) (eCFR current through 2026-08-19) already required you to implement the employer’s emergency response plan, function in Incident Command System (ICS), select PPE, perform control, and implement decontamination. 11.5.1 is how you know those verbs actually worked.
Compare actual conditions to the IAP — not to hope
11.5.1 given: a hazardous materials/WMD incident, results of the incident analysis, an assignment, current incident conditions, tactics taken, and approved communication equipment. The outcome is four verbs: compare, determine effectiveness, modify, communicate.
Predicted behavior came from 11.2.4 (predict material and container behavior) and the endangered-area estimate in 11.2.5. The IAP in 11.3.1 turned that prediction into objectives: life safety, incident stabilization, environmental protection, property. Evaluation asks a blunt question: is the scene doing what the briefing said it would do?
| What you predicted / planned | What “working” looks like | What “not working” looks like |
|---|---|---|
| Valve kit stops the chlorine leak | Hissing stops; meter trend down; white cloud shrinks | Cloud unchanged or growing; LEL / toxic reading flat or rising after the kit is on |
| Downstream dike confines the spill | Product stays in the basin; storm drain dry | Dike overtops, seeps, or product is in the inlet |
| Foam blanket knocks vapor | Visible vapor down; PID / CGI trend down | Blanket breaks; readings climb as soon as you stop pouring |
| Technical decon removes product | Visual clean, instrument below the authority having jurisdiction (AHJ) action level, no secondary contamination (Chapter 8.3) | PID still alarms on the suit; ambulance crew tearing |
| Isolation keeps civilians out | Accountability matches the board; no new exposures | New patients from a parking lot you called “cold” |
Improving, static, or deteriorating is the three-word status language NFPA 11.5.1 requisite knowledge expects you to use. Improving means the control function is buying the objective. Static means the problem is not spreading and not shrinking — still a reason to change the tactic if the objective was “stop the leak,” not “admire a steady cloud.” Deteriorating means withdraw, escalate, or both.
Do not reverse APIE-T. If the container is behaving worse than predicted (pressure climbing, flame impingement you did not brief, a second leak), you are back in Analyze and Plan, not in “try the same patch harder.”
Control functions: leak, dike, cloud — TEEX’s skill
TEEX lists evaluate effectiveness of control functions as its own technician objective, next to offensive control and decon. Control functions are the tactics from Chapters 9 and 10: confinement (dike, dam, divert, retain), containment (plug, patch, chlorine kit, dome clamp, overpack, transfer). Evaluation is not a second control chapter. It is the test of those tactics.
Ask observable questions the Incident Commander (IC) can quote:
- Is the leak slowing or stopped? Listen, look, then confirm with the same instrument, same location, same lamp or sensor you used before the tactic.
- Is the dike holding? Freeboard left? Seep at the toe? Product heading for a culvert you did not staff?
- Is the vapor cloud shrinking? Wind shift can move a cloud without shrinking it. A smaller footprint upwind after a wind reversal is not success.
- Did pressure, liquid level, or sound change the way GEBMO (general emergency behavior model) said it would after you closed the valve?
If the answer is no, 11.5.1 requires you to modify tactics. Modification is a menu, not a personality trait: different kit, more confinement downstream, remote valve, foam, defensive isolation, or non-intervention. Freelancing a second wooden plug because the first one failed is not a modification of the IAP. It is the same tactic with more hope.
Decontamination: connect to Chapter 8 — do not repeat it
TEEX also lists evaluate effectiveness of decon. Chapter 8.3 already taught the bundle: visual, instrument survey, symptoms, wipe/swipe when indicated, and no secondary contamination in the cold zone or the ambulance. OSHA 1910.120(k)(2)(iv) assigns monitoring of decontamination procedures to the site safety and health supervisor and requires correction of deficiencies. 11.4.5.1(B) and 11.4.5.2(B) make evaluating mass and technical decon a technician skill.
On this page the point is IAP-level: if decon is not effective, the entry and victim-handling tactics are not finished, even if the leak is patched. You do not terminate into a dirty cold zone. You do not send a still-alarming suit to rehab because “the stations are done.” Send the wearer back or isolate, change the method, and report that the decon tactic is being modified — the same 11.5.1 communicate verb as a failed dike. There is no national OSHA “clean PID” number; action levels are AHJ-, site-, and instrument-specific. That sentence lives in 8.3. Do not invent a new one here.
Entry time, air, and heat are part of “is the tactic working?”
A chemically correct ensemble can still lose the entry. Chapter 6.3 taught heat stress, work/rest, and the buddy system. OSHA does not publish a single national “20 minutes on, 20 minutes off” table for chemical protective clothing. Do not invent one. What is testable is that work-mission duration, remaining self-contained breathing apparatus (SCBA) air, and heat are limits the IAP already accepted.
Evaluate them on the same clock as the leak:
| Limit | Question while they are still inside | Fail action |
|---|---|---|
| Stay time / IAP duration | Are they approaching the briefed work cycle or manufacturer breakthrough window? | Withdraw on the briefed clock, not “one more turn of the wrench” |
| Air | Is remaining cylinder time enough for the walk out plus decon plus a margin, or only for “almost done”? | Withdraw while they can still walk the corridor; low-air in the hot zone is an emergency |
| Heat | Confusion, staggering, cessation of sweating, or a buddy who is no longer observing? | Emergency decon and medical — heat stroke is not a chemical reading |
| Buddy / backup | Can each worker still be observed, and is backup still identically equipped and ready (OSHA (q)(3)(v)–(vi))? | Loss of a partner or of backup ends the entry |
If air, heat, or the buddy system is failing, the control function is irrelevant. You do not “finish the patch” with one technician, 400 psi, and a partner on a knee. That is how 11.5.1 and 11.4.1 both fail at the same time.
Trends over time — the 40 percent LEL trap
One reading is a snapshot. 11.5.1 requisite knowledge includes resources for identifying improving, static, or deteriorating conditions. That means repeatable monitoring: same instrument class, documented location, time stamps, and a comparison to the IAP action level — the skill Chapter 12.3 started. A technician who reports “LEL is 40 percent” without when, where, and compared to what has not evaluated progress.
The exam sentence is deliberate: “We’ve been in 20 minutes and the LEL is still 40 percent.” That is not permission to stay because you have air left. Forty percent LEL is already a serious fire/explosion problem in most AHJ action-level schemes, and static after a fifth of an hour means the offensive tactic did not change the atmosphere. Trying harder in the same PPE with the same control is how people ride a flammable cloud until the cylinder bell rings. The correct 11.5.1 path is withdraw, tell the IC the tactic failed, and modify: more ventilation from a safe location, a different control, more isolation, or non-intervention until the atmosphere changes.
Safety’s stop-work authority under OSHA 1910.120(q)(3)(viii) still applies: IDLH or imminent danger — alter, suspend, or terminate those activities and immediately inform the individual in charge of the ICS. A technician who “just needs five more minutes” after Safety has suspended the entry is freelancing against (q)(6)(iii)(C).
Report through ICS — not a side channel
11.5.1 does not say “think about it.” It says communicate the status of tactics. 11.4.1 already required reporting observations to the hazardous materials branch director or group supervisor, the Operations Section Chief, or the IC. Evaluation uses the same pipe.
Formal progress in NIMS is not a novel:
- Verbal status to the Hazmat Group Supervisor on the tactical channel: product, tactic, improving/static/deteriorating, remaining air, next action needed.
- Safety Officer / Assistant Safety Officer — Hazardous Materials gets heat, IDLH, and decon-failure traffic immediately — not after the press briefing.
- ICS 214 (Activity Log) and monitoring logs time-stamp the trend so the next operational period does not guess.
- Updates to ICS 208 HM (Site Safety and Control Plan) and ICS 202 objectives when the tactic or the zone map changes.
A technician who only tells a partner on a private channel has not reported. A technician who waits until termination to mention that the dike was overtopping for an hour has not evaluated.
Continue, modify, withdraw, or escalate — then loop
The evaluate loop is closed:
- Monitor (instruments, visual, entry times, air, heat, decon checks).
- Compare to IAP objectives and predicted behavior.
- Continue if objectives are being met and limits are intact.
- Modify tactics or escalate resources if progress is partial or the prediction was wrong.
- Withdraw if the plan is failing, limits are expiring, or Safety has stopped the job.
- Terminate emergency operations only when the scene is stabilized and hazards are controlled — that handoff is Section 16.2 / JPR 11.6.1, not a substitute for 11.5.1.
If you remember one sentence: compare the scene to the IAP; if the leak, the dike, the cloud, decon, air, or heat is not doing what the plan required, change the tactic or leave — do not try harder in the same PPE.
Under NFPA 470 (2022) JPR 11.5.1, what must a hazardous materials technician do when evaluating assigned tasks?
An entry team has been at a leaking flammable liquid for 20 minutes. The combustible-gas reading is still 40 percent of the LEL at the same location. Which evaluation is correct?
Which statement correctly describes progress reporting and the limits that can force a tactic change even if the leak looks smaller?
