When Communication Fails on the Job Site: Where SLPs Fit In
A crane-safety report shows why communication is a safety variable and how SLP skills transfer
Nearly every survey respondent reported communication challenges during crane lifts. In a National Safety Council Work to Zero and NCCCO Foundation survey of 376 operators, riggers, signalpersons, supervisors, and safety leaders, 98% reported communication challenges during crane lifts in the previous 90 days.
Safety and Health Magazine covered the report, and the finding is not just a construction problem. It is a direct view of how SLP training in speech therapy techniques, message clarity, listening under noise, and standardized signaling, maps onto life-or-death work, skills central to SLP Crisis Response. Safety communication is becoming a preventable failure mode, not a soft skill.
What the Crane-Lift Communication Report Found
Treat crane-safety failures as purely technical defects and the real cause is easy to miss. Viewed as communication breakdowns, the same failures become familiar territory for SLPs.
Communication challenges are the norm
Safety and Health Magazine reported communication problems common during crane lifts in its coverage of The State of Rigging and Signaling in Crane Operations, developed by the National Safety Council's Work to Zero initiative with the NCCCO Foundation. The report drew on 376 survey responses from operators, riggers, signalpersons, supervisors and safety leaders. About 98% said they experienced communication challenges during lifts at least sometimes in the previous 90 days.1 Common causes included weather, noise, limited line of sight and inconsistent signaling.1
Human and organizational factors lead
Nonstandard signaling practices contributed to increased risk and confusion on jobsites. Production pressure, inadequate supervision and worker distraction appeared more often as contributors to unsafe rigging practices than technical errors did.2 The failure point was frequently the people and procedures around the message, not the machinery.
Certification creates a clearer signal
Certified riggers and signalpersons were consistently viewed by peers as more effective than noncertified personnel.1 That finding underscores a familiar SLP principle: standardized communication protocols reduce ambiguity in high-stakes moments.
Why Communication Failure Analysis Matters More Than Blaming Technical Error
Blaming technical error often misses the real reason a signal fails. In crane operations, the Work to Zero and NCCCO Foundation report found that production pressure, inadequate supervision, and worker distraction contributed to unsafe rigging practices more frequently than technical mistakes. Those are human and organizational factors, not just equipment or skill gaps.
A simple breakdown sorts communication failures into four categories: message design, channel or noise, listener or receiver, and organizational or cultural. Nonstandard hand signals fall under message design. Radio interference or a blocked line of sight falls under channel or noise, within the scope of auditory processing research in speech pathology. A distracted operator falls under listener or receiver, a focus of communication partner training. Rushed schedules and weak supervision fall under organizational or cultural.
Sorting an incident into these categories lets a team fix the actual cause instead of retraining everyone generically. For example, if a signalperson uses a nonstandard gesture because production pressure skipped the morning briefing, the fix is to protect that briefing, not to repeat signal training for the whole crew.
How SLP Skills Transfer to Safety-Critical Settings
As speech-language pathology keeps expanding beyond traditional clinical walls, safety-critical workplaces are becoming a natural place to apply communication expertise. The crane-lift survey described earlier makes the connection concrete: most respondents experienced communication challenges during lifts, and nonstandard signaling was a recurring risk.
From speaker treatment to communication system
SLPs are trained through immersive SLP clinical training to assess the whole communication loop, not just one speaker's production. That includes message design: making instructions short, explicit, and ordered. It includes active listening and confirmation: checking back, repeating key numbers, and closing the loop before action. It includes noise and environmental barriers: physical distance, radio lag, engine noise, and visual obstructions. It includes jargon and plain language: deciding when crew shorthand helps and when it confuses a less familiar partner. It includes standardized signaling: replacing informal gestures with agreed signals that transfer across teams.
Nonstandard signaling works like idiosyncratic communication in speech-language disorders. It may be efficient among familiar partners, but it breaks down when a new partner, a different crew, or a high-stress moment enters the loop. SLPs can help teams build shared, teachable communication protocols without claiming they are safety inspectors or crane operators. The value is transferable: analyze the system and the partner, not just the individual who spoke.
High-Risk Industries and Where Communication Breaks Down
The same breakdown types recur across high-risk industries because workers rely on compressed, high-stakes messages delivered under noise, time pressure, and divided attention. Standardized wording, closed-loop confirmation, and listener training become safety controls rather than soft skills. The examples below are illustrative patterns, not measured findings.
| Industry | Typical Breakdown | SLP-Relevant Strategy |
|---|---|---|
| Crane operations | Nonstandard hand signals or radio phrasing during lifts, often under production pressure | Replace idiosyncratic signals with standardized multimodal cues and teach closed-loop repeat-backs |
| Construction | Multi-team noise, jargon, and rushed handoffs between trades | Simplify message content, reduce environmental noise, and train workers to confirm receipt before acting |
| Healthcare | Handoff omissions, abbreviations, and interruptions during shift changes or emergencies | Apply structured read-back and plain-language checklists for critical safety words and medication names |
| Aviation | Crew communication load, similar-sounding callouts, and role ambiguity in time-critical checklists | Design unambiguous phraseology and rehearse degraded listening conditions, similar to cockpit resource management training |
| Emergency response | Radio overload, overlapping channels, and unclear incident command updates | Develop scripted status reports and a single-speaker protocol with explicit confirmation of priority messages |
What an SLP Can Assess and Address at Work
What a workplace communication assessment covers
An SLP can map the actual communication demands of a task: who gives and receives instructions, what timing is required, how much background noise and distance sit between speaker and listener, and whether procedures leave room for ambiguity. The assessment also reviews partner behavior: do coworkers confirm, repeat, or rush? It then checks the worker's own speech, language, hearing, and cognitive-communication skills against those demands.
Accommodations and scripts
- Aphasia: use a written cue card with step-by-step lift signals the worker can point to.
- Hearing loss: pair a visual light signal with radio calls for a technician who misses high-frequency alarms.
- TBI: reduce multitasking and provide a single, written checklist for complex rigging sequences.
- Stuttering: allow extra response time and use written confirmation instead of requiring rapid spoken replies for Stuttering in Adults.
- AAC users: install a tablet with preloaded safety phrases and request-for-clarification buttons using AAC devices suited to the jobsite.
- Multilingual workers: post bilingual signal charts and teach a shared, plain-language phrase set, drawing on Multilingual Speech Therapy.
Scripts help too. A simple clarification protocol might be: "Say again, I heard X. Confirm or correct." Escalation and feedback scripts should name the problem, not the person.
SLP vs. executive coach
Choose an SLP when a communication disorder, hearing loss, brain injury, or speech condition affects job performance. Choose an executive coach for leadership style, executive presence, or general confidence.
How Employers Can Prevent Communication Breakdowns Before Incidents
More safety-critical employers are treating communication as a preventable failure mode, not just a soft skill to mention during onboarding. In the crane-lift survey, peers consistently rated certified riggers and signalpersons as more effective than noncertified personnel, which points to training and standardization as practical levers.
Prevention checklist for high-risk work
- Standard phrases: Use an agreed set of exact commands for high-risk moves, stops, and emergencies.
- Closed-loop confirmation: Require the receiver to repeat the critical message back and the sender to verify it.
- Clarification scripts: Give workers a standard way to say "clarify that" or "hold" without permission.
- Supervisor training: Have supervisors model unrushed, clear talk and reinforce repeat-backs in briefings.
- Psychological safety: Make it safe to pause work and ask for clarification without penalty.
- Structured handoffs: Use a standard sequence for shift changes and equipment transfers, covering what, where, hazards, and next action.
What the evidence does and does not show
A 2025 analysis of 374 surgical and anesthesia adverse events found 62% involved at least one communication breakdown, mostly unclear risk disclosure at 41% or missing closed-loop verification at 29%. Those figures describe where failures concentrate, not how much one protocol reduces incidents. Aviation sources link communication lapses to about 13% to 24% of safety incidents, but controlled incident-reduction estimates are thin.2 The crane survey offers a cautious parallel: certified signalpersons were seen as more effective, not audited as preventing accidents. Employers should track near misses, repeat-back compliance, and stop-work use before claiming hard safety gains.
Adjacent Roles and How to Build Credentials
SLPs can move into non-clinical jobs for speech pathologists such as safety communication and human factors roles without becoming safety engineers, but the strongest applicants pair clinical communication expertise with additional SLP degrees & endorsements. The adjacent role families are human factors, safety training, corporate communication, and occupational health.
OSHA's voluntary Outreach program offers 10-hour and 30-hour courses1. The 10-hour course fits entry-level workers, while the 30-hour version is for workers with some safety responsibility. Outreach trainers are authorized, not certified, and completion does not fulfill every OSHA training requirement1.
University human factors certificates vary. Embry-Riddle offers an online 12-credit graduate certificate2, Old Dominion requires 12 credits including PSYC 307, PSYC 344, PSYC 410, and PSYC 4133, and Tufts focuses on medical devices and systems4. For corporate communication, eCornell's certificate costs $3,750 and awards 4 CEUs5, while Texas State offers a 9-credit graduate certificate6.
SLPs are distinct from executive coaches, occupational therapists, and psychologists. SLPs contribute message design, listening, jargon reduction, and standardized communication protocols; they do not provide psychotherapy, OT interventions, or executive coaching.
A concrete first step is the OSHA 10-hour Outreach course plus one human factors elective or a short certificate. That combination signals safety literacy while preserving the SLP's communication expertise.
