5 Pre-Task Hazard Assessment Templates for Construction Crews [Free Download]

Why Pre-Task Hazard Assessments Are Worth the 10 Minutes

The OSHA Fatal Four (falls, struck-by, caught-in/between, and electrocution) account for 60% of all construction worker deaths. Falls alone killed 421 workers in 2023. These aren't freak accidents. They're the predictable result of known hazards that weren't identified and controlled before work started.

A pre-task hazard assessment template gives your crew a structured way to look at what they're about to do, spot the hazards specific to that task, and agree on controls before anyone picks up a tool. Call it a JHA, JSA, FLHA, or PTP. The format varies, but the goal is the same: make sure the crew is thinking about what could hurt them before it does.

OSHA formally recommends the Job Hazard Analysis methodology (OSHA 3071) for this. Many state plans and GC contract requirements go further and mandate them. Either way, a completed pre-task assessment is one of the strongest pieces of documentation you can have if an incident happens.

The five templates below are scoped to the work types that show up most often in fatality reports. Use them on paper, in a spreadsheet, or pull them into a digital workflow. What matters is that crews actually fill them out before work starts, not after the fact.

What Every Pre-Task Hazard Assessment Template Should Include

Generic checklists miss hazards. A form that asks 'any electrical hazards?' doesn't do much for a crew about to trench next to an energized line. Task-specific templates force the right questions at the right time.

That said, every pre-task hazard assessment template should cover the same core sections regardless of work type. Before you look at the task-specific templates below, make sure your baseline version includes these fields.

For a deeper look at how pre-task assessments fit into your broader safety inspection program, see our guide on construction safety inspections at /blog/complete-guide-construction-safety-inspections.

• Project name, location, date, and work order or permit number
• Crew roster with names and roles (everyone who signs is accountable)
• Scope of work: what specifically is being done today, not just the trade
• Task steps broken into discrete activities (OSHA JHA methodology: list each step, identify hazards per step, assign controls)
• Hazard identification: physical, chemical, biological, ergonomic, and environmental hazards
• Risk rating: likelihood x severity for each hazard (even a simple Low/Medium/High scale works)
• Controls: hierarchy of controls. Elimination first, then substitution, engineering, administrative, PPE last.
• PPE requirements specific to this task
• Permit references: hot work, confined space, excavation, electrical — whatever applies
• Emergency contacts and nearest hospital route
• Crew sign-off with date and time

Template 1: General Site Prep Pre-Task Hazard Assessment

Site prep work looks low-risk until a crew member walks into an unmarked overhead line or a grader hits an unmarked gas main. Mobilization, clearing, grading, and layout work involves multiple trades in close proximity, heavy equipment, and utilities that aren't always marked yet.

Use this template any time crews are working on initial site setup, clearing operations, or layout activities where site conditions haven't been fully established.

• TEMPLATE FIELDS:
• Project name / site address / date / foreman name
• Crew roster (name, role, trade)
• Scope: describe today's specific site prep activity
• SITE CONDITIONS CHECK:
• [ ] 811 utility locate request confirmed — ticket number: ___
• [ ] Overhead power lines identified — nearest line distance: ___
• [ ] Site access routes established and clear of pedestrians
• [ ] Ground conditions assessed — soft spots, slopes, standing water noted
• [ ] Traffic control in place if adjacent to active roadway
• EQUIPMENT PRE-INSPECTION:
• [ ] All equipment inspected before shift start
• [ ] Backup alarms functioning on all mobile equipment
• [ ] Spotters assigned for blind zones
• PPE REQUIRED: Hard hat, hi-vis vest, steel-toed boots, gloves, safety glasses
• EMERGENCY INFO: Nearest hospital: ___ / Site emergency contact: ___
• CREW SIGN-OFF: All crew members sign and date before work begins
• ACTIONABLE TAKEAWAY: Walk the site before the crew arrives. Hazards you find at 6:45 AM are easier to fix than ones you find at 9:00 AM with equipment running.

Template 2: Excavation and Trenching Pre-Task Hazard Assessment

Excavation is one of the most dangerous operations in construction. Cave-ins kill fast. A cubic yard of soil weighs around 3,000 pounds. OSHA 29 CFR 1926 Subpart P requires a competent person to classify soil and inspect the excavation before each shift, after rainstorms, and whenever conditions change.

This template is designed for foremen and competent persons. It walks through the regulatory requirements and the site-specific hazards that don't show up on a generic checklist.

• TEMPLATE FIELDS:
• Project name / location / date / competent person name
• Excavation dimensions: length ___ width ___ depth ___
• Permit number if applicable
• UTILITY CLEARANCES:
• [ ] 811 locate ticket confirmed — ticket #: ___
• [ ] All utilities physically marked in work zone
• [ ] Hand-dig or vacuum excavation within 18" of marked utilities
• SOIL CLASSIFICATION (required by OSHA):
• [ ] Type A — cohesive soil, unconfined compressive strength >1.5 tsf
• [ ] Type B — cohesive soil, UCS 0.5–1.5 tsf, or previously disturbed
• [ ] Type C — granular soil, UCS <0.5 tsf, water seepage, or layered
• PROTECTIVE SYSTEM:
• [ ] Sloping to OSHA angle for soil type
• [ ] Shoring installed per manufacturer specs
• [ ] Trench box in place — inspect for damage before use
• ACCESS/EGRESS:
• [ ] Ladders or ramps within 25' of every worker in trench
• [ ] Spoil pile minimum 2' from trench edge
• ATMOSPHERIC TESTING (if >4' depth or enclosed):
• [ ] Oxygen: 19.5–23.5% [ ] Combustibles: <10% LEL [ ] CO: <35 ppm
• PPE REQUIRED: Hard hat, hi-vis, steel-toed boots, gloves, safety glasses. Supplied air if atmospheric hazard present.
• CREW SIGN-OFF: Competent person signs. All crew members sign before entering.
• ACTIONABLE TAKEAWAY: Soil classification changes after rain. If it rained last night, re-classify before the crew goes in. Don't rely on yesterday's assessment.

Template 3: Working at Heights Pre-Task Hazard Assessment

Falls killed 421 construction workers in 2023. That's more than one per day. Scaffolding, aerial lifts, roofing, steel erection, and ladder work all fall under this template.

The most common failure point isn't equipment. It's verification. Workers assume the equipment was checked on a previous shift. This template makes verification explicit, which is also why tying it to equipment inspection records matters. If your crew uses QR codes to pull up equipment inspection history before starting, they're not guessing whether that scissor lift was cleared this morning.

• TEMPLATE FIELDS:
• Project name / location / date / foreman name
• Work type: [ ] Scaffolding [ ] Aerial lift [ ] Roofing [ ] Ladder [ ] Steel erection [ ] Other: ___
• Maximum working height: ___
• FALL PROTECTION PLAN:
• [ ] Fall protection method identified: guardrail / PFAS / safety net
• [ ] Anchor points rated for fall loads and inspected
• [ ] Harness inspected for damage — date of last inspection: ___
• [ ] Lanyard/SRL inspected — no cuts, fraying, or corrosion
• EQUIPMENT INSPECTION:
• [ ] Scaffold — base plates set, pins secured, planking inspected
• [ ] Aerial lift — pre-operation inspection completed, capacity check done
• [ ] Equipment inspection record reviewed (scan QR code if available)
• ENVIRONMENTAL CONDITIONS:
• [ ] Wind speed checked — work suspended if >28 mph for aerial lifts
• [ ] No ice, standing water, or wet surfaces on walking/working surfaces
• FALLING OBJECTS:
• [ ] Toeboards in place on scaffold platforms
• [ ] Exclusion zone established below work area
• [ ] Tool lanyards in use for hand tools above 6'
• RESCUE PLAN:
• [ ] Rescue method identified if worker falls and is suspended: ___
• [ ] Rescue equipment on site: ___
• PPE REQUIRED: Full body harness, hard hat, safety glasses, steel-toed boots. Hi-vis if near equipment traffic.
• CREW SIGN-OFF: All workers sign before ascending.
• ACTIONABLE TAKEAWAY: Walk the anchor points yourself. Don't sign off on an anchor you haven't physically touched.

Template 4: Hot Work Pre-Task Hazard Assessment

Welding, cutting, grinding, and torch work create ignition sources. On a construction site, flammable materials aren't always obvious. Vapors from adhesives, sawdust in wall cavities, or fuel near equipment can turn a routine weld into a fire. OSHA 29 CFR 1926.352 requires fire prevention measures for hot work. Most GC contracts also require a hot work permit with staged sign-off.

FieldScout's permit workflows handle multi-stage digital sign-off for hot work: foreman authorization, fire watch assignment, and supervisor approval all in one record. But even if you're doing this on paper, the template below covers the critical checkpoints.

• TEMPLATE FIELDS:
• Project name / location / date / hot work permit number
• Worker name(s) / trade / type of hot work: ___
• Specific location on site: ___
• AREA CLEARANCE CHECK:
• [ ] All flammable/combustible materials removed or protected within 35' of work
• [ ] Floor openings and wall penetrations covered or sealed
• [ ] Adjacent areas on opposite side of walls checked
• [ ] Area wetted down if combustible dust present
• FIRE WATCH:
• [ ] Fire watch assigned — name: ___
• [ ] Fire watch will remain 30 minutes after work stops
• [ ] Fire watch has unobstructed view of work area
• FIRE SUPPRESSION:
• [ ] Fire extinguisher type and size appropriate for materials present
• [ ] Extinguisher inspected and within service date
• [ ] Location: within 30' of work area
• VENTILATION:
• [ ] Natural or mechanical ventilation confirmed adequate
• [ ] Fume extraction in use for enclosed spaces
• PPE REQUIRED: Welding helmet, leather gloves, fire-resistant clothing, leather boots, safety glasses, hearing protection.
• PERMIT SIGN-OFF: Foreman authorization, fire watch acknowledgment, supervisor approval
• ACTIONABLE TAKEAWAY: The 35-foot clearance rule sounds like a lot until you look at a real floor. Walk the radius before you strike an arc, not during.

Template 5: Electrical Work Pre-Task Hazard Assessment

Electrocution is the third leading cause of construction fatalities in the OSHA Fatal Four. Arc flash injuries are often more severe than electrocution because they're not always fatal but cause catastrophic burns. OSHA 29 CFR 1926 Subpart K governs electrical safety in construction. NFPA 70E sets the arc flash boundary and PPE standards most GCs incorporate by contract.

LOTO (lockout/tagout) is the most critical control for electrical work, and it's also one of the most frequently violated procedures on job sites. Tamper seal verification closes a real gap here: if your LOTO devices have tamper seals and crews check seal integrity before work starts, you catch unauthorized re-energizations before someone gets hurt. FieldScout's tamper seal management ties this directly into the pre-task checklist so it doesn't become a separate step that gets skipped.

• TEMPLATE FIELDS:
• Project name / location / date / electrician name / license number
• Circuit/equipment description: ___
• Voltage: ___ / Estimated incident energy: ___ cal/cm²
• LOCKOUT/TAGOUT VERIFICATION:
• [ ] Energy source(s) identified — list all: ___
• [ ] All energy sources isolated and locked out
• [ ] Lockout devices applied — tamper seals intact (check serial numbers if tracked digitally)
• [ ] Stored energy released (capacitors discharged, springs released, pressure bled)
• [ ] Zero-energy verification completed with test instrument
• ARC FLASH BOUNDARY:
• [ ] Arc flash hazard label present on equipment
• [ ] Restricted approach boundary established: ___
• [ ] Flash protection boundary established: ___
• [ ] Barricades and signage in place
• PPE REQUIRED (per NFPA 70E arc flash category):
• [ ] Arc-rated clothing — minimum cal/cm² rating: ___
• [ ] Face shield / arc flash hood
• [ ] Insulated gloves — class: ___
• [ ] Safety glasses under face protection
• [ ] Dielectric footwear if working on energized systems
• WORK PERMIT:
• [ ] Energized electrical work permit obtained if work cannot be de-energized
• [ ] Permit signed by qualified person
• CREW SIGN-OFF: All workers on task sign before work begins.
• ACTIONABLE TAKEAWAY: Test for voltage yourself. Don't assume the previous crew left it de-energized. Test twice, then work.

How to Get Your Crew to Actually Use These Templates

The biggest problem with pre-task hazard assessment templates isn't the template. It's the habit. Crews fill them out after the fact, or the foreman fills out everyone's signatures at once, or the form disappears into a job trailer and never gets reviewed.

A few things that actually help: tie the PTHA to daily toolbox talks so it happens as part of the morning routine, not as an extra step. Assign foreman ownership — someone has to be accountable for getting it done before tools hit the ground. And when conditions change mid-day (a rainstorm, a scope change, a new subcontractor on site), require a new assessment. The original one doesn't cover changed conditions.

Paper works, but it has real limits. Paper forms get wet, lost, and filled out after the fact with no timestamp to prove otherwise. Digital PTHAs completed in a browser before work starts create a timestamped record that holds up in audits and incident investigations. FieldScout works in any mobile browser (no app download, no account setup for field crews) so adoption friction is low. Foremen can pull up the right template by work type, complete it with their crew, and the record is attached to the job the moment they submit.

Frequently Asked Questions About Pre-Task Hazard Assessment Templates

What is the difference between a JHA, JSA, FLHA, and pre-task hazard assessment? They're the same concept with different names. Job Hazard Analysis (JHA) and Job Safety Analysis (JSA) are the most common in the US. Field Level Hazard Assessment (FLHA) is common in Canadian construction. Pre-Task Plan (PTP) and Pre-Task Hazard Assessment (PTHA) are used interchangeably at many GCs. The methodology is identical: identify the task, break it into steps, identify hazards per step, assign controls.

Does OSHA require pre-task hazard assessments? OSHA strongly recommends JHA methodology through OSHA 3071 and includes hazard assessment requirements in specific standards (excavation, confined space, electrical, fall protection). Many state OSHA plans and GC contract requirements go further and mandate written PTHAs for specific work types. When in doubt, check your subcontract agreement. It likely has language about it.

How often should a new assessment be completed? A new pre-task hazard assessment is required each time the scope of work changes, when site conditions change (weather, new excavation, new trade working nearby), when a new crew member joins the task, or after a near-miss or incident. One assessment per day per crew is a starting point, not a ceiling.

Can I use one template for all work types? Not effectively. A generic checklist asks generic questions and misses task-specific hazards. The difference between what you catch with an excavation-specific template versus a generic form is significant, and OSHA's own guidance recommends task-specific JHAs for high-hazard operations.

Run Your Pre-Task Assessments Digitally — No App Required

These templates give you a starting point. But if you want timestamped records, crew sign-offs that hold up in an audit, and permit workflows that stay connected to the job, paper and spreadsheets get expensive fast when something goes wrong.

FieldScout runs in your browser. Your crew doesn't install anything. You get digital pre-task assessments, permit workflows, QR code equipment inspections, and tamper seal management in one place.
