Toolbox talks for general contractor crews
The talks below match the hazards general contractor crews actually face: multi-trade coordination, falls, struck-by from equipment, excavations, silica dust, housekeeping. Every talk is free, comes in English and Spanish, and includes a printable sign-in sheet so the meeting is documented.
General Contractor-specific talks
Fall Protection Basics
In 2024, BLS counted 389 deaths from falls, slips, and trips in private construction, over one third of all construction deaths. OSHA requires fall protection at 6 feet in construction work. A harness in the truck protects nobody; today we make sure everyone knows what to wear, where to tie off, and what to check before stepping near an edge.
29 CFR 1926.501 · 29 CFR 1926.502 · 29 CFR 1926.503 · EN/ES
Trench and Excavation Safety
Soil is heavy, and when a trench wall lets go there is no outrunning it. OSHA reported 22 trench deaths in the first half of 2022 alone, more than in all of 2021. Every trench 5 feet or deeper needs a protective system before anyone steps in, unless it is in stable rock, and the competent person decides what kind.
29 CFR 1926.651 · 29 CFR 1926.652 · EN/ES
Silica Dust Control
That white cloud when you cut concrete or block is crystalline silica, and OSHA says about 2.3 million people in the U.S. are exposed to it at work. Silicosis has no cure and can show up years after the exposure. OSHA's silica rule sets the controls; water and vacuums are cheap, lungs are not.
29 CFR 1926.1153 · EN/ES
Scaffold Safety
Scaffolds put whole crews at height on a structure someone assembled that morning. Scaffolding was the sixth most cited OSHA standard in fiscal year 2025. Planking, guardrails, access, and the competent person's inspection are what stand between routine and disaster.
29 CFR 1926.451 · 29 CFR 1926.454 · EN/ES
Struck-By: Working Around Heavy Equipment
Struck-by is one of OSHA's Focus Four hazards in construction. The operator may not see you, may not hear you, and is often watching the load, not the ground. Eye contact before approach is the rule that keeps people out of blind spots.
29 CFR 1926.600 · 29 CFR 1926.601 · 29 CFR 1926.602 · EN/ES
Confined Space Awareness
Crawl spaces, vaults, pits, tanks, large ducts: spaces big enough to enter but not meant to work in can hold bad air you cannot see or smell. When someone goes down, the urge is to jump in after them, and that is how one victim becomes two. Awareness means knowing which spaces need a permit before anyone’s head crosses the plane.
29 CFR 1926.1203 · 29 CFR 1926.1204 · EN/ES
Aerial Lift Safety
Boom lifts and scissor lifts put you high up on a platform that moves. OSHA lists tip-overs, ejections, falls, electric shock, and getting crushed against overhead objects as ways lifts hurt or kill. Many of these start with something small: a pothole, a gust, or an unbuckled harness on a boom.
29 CFR 1926.453 · 29 CFR 1926.502 · EN/ES
Forklift and Telehandler Safety
A forklift or telehandler can roll over or strike a worker on foot, and a load can fall off the forks. OSHA requires every operator to finish training before running the machine, with a performance evaluation at least once every three years. Today we cover the rules for operators and for everyone on foot.
29 CFR 1910.178 · 29 CFR 1926.602 · EN/ES
Temporary Power, Cords, and GFCI
Construction sites run on extension cords, and extension cords in mud, water, and traffic are how electricity finds a path through a person. OSHA requires GFCI protection or an assured grounding program on temporary 120-volt receptacles, and our rule is GFCI on every one. A GFCI turns a would-be shock into a tripped breaker.
29 CFR 1926.404 · 29 CFR 1926.405 · 29 CFR 1926.416 · EN/ES
Crane and Rigging Awareness
You do not have to be the crane operator to be killed by the crane. People on the ground get hurt under the load, inside the swing radius, or guiding a load with their hands when it shifts. If the load is in the air, gravity is in charge.
29 CFR 1926.1400 · 29 CFR 1926.1417 · 29 CFR 1926.1419 · 29 CFR 1926.1425 · 29 CFR 1926.251 · EN/ES
Rebar and Impalement Protection
Exposed vertical rebar is a bed of spears. OSHA requires guarding every piece of sticking up rebar a worker could fall onto, so it cannot impale them. OSHA also says plain mushroom caps usually protect only from scrapes and cuts, not impalement.
29 CFR 1926.701 · EN/ES
Underground Utility Strikes
Hitting a gas line or a buried power cable can cause serious injuries or even death. OSHA requires you to find where underground lines are likely to be and get the utility companies to mark them before you dig. Marks are only as good as what happens after, so NIOSH says to dig by hand within 2 feet of any mark.
29 CFR 1926.651 · EN/ES
Overhead Power Line Safety
Power lines do not look dangerous. They look like every other wire until a ladder, a boom, or long stock gets too close. Electricity can arc across a gap without touching anything, which is why OSHA sets minimum clearance distances. Today we cover the distances and how to keep everything outside them.
29 CFR 1926.1408 · 29 CFR 1926.416 · EN/ES
Wind and Weather Hazards
Weather is a schedule problem until it becomes a safety problem, and the line between the two is sharper than most crews treat it. Wind turns sheet goods into sails, rain turns roofs into slides, and lightning does not care that you are almost done with the row.
29 CFR 1926.451 · OSH Act 5(a)(1) · EN/ES
Skylight and Roof Opening Protection
A skylight looks solid and holds nothing. Workers fall through skylights that break under their weight, and open roof holes catch workers walking backward with material. OSHA requires every hole and skylight a worker can fall through to be guarded or covered. Today we treat every skylight like an open hole, because structurally, that is what it is.
29 CFR 1926.501 · 29 CFR 1926.502 · EN/ES
Leading Edge Work
A leading edge is an edge that moves: the unprotected side of a deck or roof that advances as you build it. Guardrails are hard to keep up with an edge that changes every hour, which is why leading edge work has its own fall protection rules. Today we talk about protecting the edge that will not stand still.
29 CFR 1926.501 · 29 CFR 1926.502 · EN/ES
Job-Made Ladders and Stair Rails
Site-built ladders and temporary stairs carry the whole job up and down, and they get built fast out of whatever lumber is close. OSHA has specs for job-made ladders and requires stair rails on temporary stairs, because a bad cleat or a missing rail at the main access point puts every single worker at risk several times a day. Today we check the access everyone uses and nobody looks at.
29 CFR 1926.1053 · 29 CFR 1926.1052 · EN/ES
Stairways and Temporary Stairs During Construction
Permanent stairs get used long before they are finished: no rails yet, no treads yet, pans full of debris. OSHA has specific rules for stairways used during construction, including when pan stairs can be climbed and what rails must be up. Today we make sure the stairwell is not the most dangerous part of the job.
29 CFR 1926.1052 · 29 CFR 1926.25 · EN/ES
Excavation Protective System Selection
OSHA says a cubic yard of soil can weigh as much as a compact car, and a collapsing trench wall does not give you time to climb. OSHA requires a protective system in every excavation 5 feet or deeper unless it is all stable rock: sloping, benching, shoring, or a shield. Which one depends on soil, depth, water, and what is next to the hole, and it is never the crew guessing.
29 CFR 1926.652 · 29 CFR 1926.651 · EN/ES
The Competent Person Daily Excavation Checklist
OSHA requires a competent person to inspect every excavation daily before work starts, and again after rainstorms or anything that changes conditions. Competent means trained to spot the hazards AND authorized to stop work and fix them. Today we go through what that daily inspection actually looks at, so the whole crew knows what a passed inspection means and what to watch between inspections.
29 CFR 1926.651 · 29 CFR 1926.652 · EN/ES
Working Around Dump Trucks and Haul Roads
A loaded dump truck is heavy, and the driver cannot see a person standing behind the tailgate or beside the right front wheel. Trucks backing or turning where workers on foot do not expect them is a real danger on earthwork jobs. Today we set the traffic rules between boots and trucks: where trucks run, where people walk, and who controls the backing.
29 CFR 1926.601 · 29 CFR 1926.602 · EN/ES
Skid Steer Safe Operation
The skid steer is small enough that people stop respecting it, and that is how it hurts them: crushed between the bucket and the frame, run over on a tight site, or thrown from the cab operating without the seat bar down. It turns in place with zero warning and carries loads that block the view. Today we cover the rules for operators and, just as important, for everyone on foot around one.
29 CFR 1926.20 · 29 CFR 1926.21 · EN/ES
Excavator Swing Radius and Quick Couplers
The counterweight of a swinging excavator moves fast and hits hard. Add a quick coupler that was not fully locked, and a bucket can drop off mid-swing. Today we mark the circle nobody enters and the check nobody skips.
29 CFR 1926.602 · EN/ES
Masonry Wall Bracing and the Limited Access Zone
A fresh masonry wall is just stacked weight until it cures and gets tied into the structure. OSHA requires a limited access zone before any masonry wall is built, and bracing for walls over 8 feet until permanent support is in place. Today we cover the zone, the braces, and who is allowed near the wall.
29 CFR 1926.706 · EN/ES
Tilt-Up Panel Safety
A tilt-up panel is a huge slab of concrete, and from the moment the crane breaks it off the casting bed until the last brace bolt is torqued, gravity is trying to lay it back down. OSHA requires tilt-up and precast panels to be supported until permanent connections are complete, and keeps workers out from under panels being lifted. Today we cover lift day discipline: rigging, the fall zone, and bracing.
29 CFR 1926.704 · EN/ES
Demolition Pre-Planning Basics
Demolition is construction in reverse, with one big difference: the building was not designed to come apart, and every cut changes how it stands. OSHA requires an engineering survey before demolition starts, checking the structure condition and the possibility of unplanned collapse, plus utilities cut and capped. Today we cover what must be answered before the first swing of a hammer.
29 CFR 1926.850 · 29 CFR 1926.20 · EN/ES
Mold Awareness During Demo and Water Damage Work
Open a wet wall and you may release a face full of mold spores. Mold can grow where things stayed wet for more than a day or two: behind drywall, under flooring, inside HVAC. For sensitive people it means allergies and irritation, and it can set off asthma attacks in people with asthma. OSHA rules on respirators and protective gear still apply when we work with it. Today: recognize it, contain it, protect your lungs.
29 CFR 1910.134 · 29 CFR 1926.95 · EN/ES
Welding Fume Exposure and Ventilation
That plume rising off your weld is metal fume and gas, and your lungs are the filter if ventilation is not. OSHA says welding fume can cause metal fume fever and, over time, lung damage, and stainless steel welding makes hexavalent chromium, which can cause cancer. OSHA requires ventilation for welding in confined spaces, and in enclosed spaces when the metal has zinc, lead, cadmium, chromium, mercury, or beryllium. Today: get your head out of the plume and air moving through the work.
29 CFR 1926.353 · 29 CFR 1926.55 · EN/ES
Arc Welding Electrical Safety
Welders hold a live electrical circuit all day, and wet gloves, damaged leads, and sloppy electrode handling can put that current through your body instead of the arc. OSHA arc welding rules in 29 CFR 1926.351 cover the holders, the leads, the grounding, and the habits. Today we cover all of it.
29 CFR 1926.351 · EN/ES
Powder-Actuated Tool Certification and Use
A powder-actuated tool uses a powder charge to drive a pin into concrete or steel, and OSHA says it operates like a loaded gun. If the base material is too soft, the pin can pass right through and fly out the other side. OSHA lets only workers trained on the exact tool in use operate one. Today we treat the tool with the same respect as a loaded gun.
29 CFR 1926.302 · EN/ES
Nail Gun Trigger Safety and Ricochet
Nail guns are responsible for about 37,000 emergency room visits each year, and 60% of them are work-related. The risk of a nail gun injury is twice as high with a contact (bump) trigger as with a full sequential trigger. Bump triggers can fire a nail you did not mean to fire, which is how guns nail hands, legs, and coworkers. Today: triggers, ricochets, and keeping your free hand out of the line of fire.
29 CFR 1926.302 · EN/ES
Table Saw and Miter Saw Station Safety
The cut station makes cut after cut all day, and every one puts fingers close to a spinning blade. OSHA rules say each hand-fed table saw needs a hood guard over the blade, and every fixed woodworking tool needs a disconnect switch that can be locked or tagged off. OSHA also says safety guards must never be removed when a tool is being used. Today we set up the station right and keep hands where blades are not.
29 CFR 1926.304 · EN/ES
Reciprocating Saw and Blade Binding
The recip saw is the demo workhorse, and it bites in two ways: the blade binds and the saw bucks back at you, or the blade breaks through and keeps going into whatever is next, including your leg or a live cable. Blind cuts into walls and floors are where recip saws find pipes, wires, and fingers. Today: control the bind, plan the breakthrough, and know what is behind the cut.
29 CFR 1926.302 · 29 CFR 1926.304 · EN/ES
Pressure Washer Injection Injuries
A pressure washer stream can cut skin and push water, soap, and dirt under it. A small hole in the skin can hide a much worse injury, so it needs a doctor the same day. Add wet surfaces, ladders, and electricity, and the wash-down job deserves more respect than it gets. Today: the stream, the footing, and the wound that looks like nothing.
29 CFR 1926.302 · 29 CFR 1926.95 · EN/ES
Winter Concrete: Blankets, Enclosures, and Heater Fires
Cold-weather concrete means blankets, poly enclosures, and heaters running unattended for days, which is a fire triangle we build on purpose. Curing blankets against heater casings, enclosures that trap heat, and nobody on site at 2 a.m. when it starts smoldering. OSHA fire prevention rules apply to temporary heating around combustibles. Today we plan the cure so the pour does not burn.
29 CFR 1926.150 · 29 CFR 1926.151 · 29 CFR 1926.154 · EN/ES
Work Zone Traffic Control Basics
When your work zone touches a road, every passing car is a hazard. Drivers are distracted, sun-blinded, and annoyed by the cone line, and workers get comfortable stepping past it. OSHA requires signs, signals, and barricades that follow the MUTCD, the federal traffic control manual. Today: the zone layout, the buffer that saves lives, and never trusting a driver you have not made eye contact with.
29 CFR 1926.200 · 29 CFR 1926.201 · EN/ES
Flagger Operations and Positioning
The flagger stands closer to moving traffic than anyone else on the job. OSHA requires flagger signaling, and the warning garments flaggers wear, to follow Part 6 of the MUTCD, and OSHA guidance says flaggers should use STOP/SLOW paddles and class 2 or 3 garments. Position and escape route decide whether a bad driver ruins your day or ends it. Today: where to stand, how to signal, and when to bail.
29 CFR 1926.201 · EN/ES
Night Work Lighting and Visibility
Everything on a night job is the same as the day job, minus the light your eyes were built for. OSHA sets minimum illumination levels for construction work areas, and the difference between lit and half-lit shows up in twisted ankles, struck-by incidents, and blade cuts that daylight would have prevented. Add glare blinding equipment operators and dark clothing swallowing workers, and light becomes the first tool of the shift.
29 CFR 1926.56 · 29 CFR 1926.201 · EN/ES
Subcontractor Coordination on Multi-Employer Sites
On a multi-employer site, the crane crew, the electricians, and the roofers can each be safe alone and still hurt each other: a load swung over another trade, power turned on under someone's hands, a floor opening cut where another crew walks. Under OSHA policy, more than one employer can be cited for the same hazard on a shared site. Today: how hazards cross crew lines here, and how we talk before they do.
29 CFR 1926.16 · 29 CFR 1926.20 · EN/ES
Housekeeping in Stairwells and Corridors
Stairwells and corridors are the arteries of the job: every worker, every load, and one day maybe a stretcher moves through them. They are also where debris drifts, cords cross, and material gets staged for a minute that becomes a week. OSHA requires work areas, passageways, and stairs kept clear. An escape route with a pallet in it is not an escape route. Today we claim the arteries back.
29 CFR 1926.25 · EN/ES
Material Storage and Rack Stability
Stored material is stored energy. A pipe rack lets go, a drywall stack tips, banded lumber shifts on uneven ground, and suddenly hundreds of pounds move at whoever is closest. OSHA storage rules require stacked material to be secured so it cannot slide, fall, or collapse, and set height limits for things like brick and lumber. A bad base, a stack too high, and pulling from the bottom are what we watch for. Today: how we stack so it stays.
29 CFR 1926.250 · EN/ES
Plastic Sheeting and Slip Hazards on Floors
Poly sheeting protects floors and finishes, and it turns them into skating rinks: plastic over smooth concrete has almost no grip, and add dust, dew, or a little mud and boots go out from under people carrying loads. Ram board, drop cloths, and taped seams have the same problem in smaller print. Today: where sheeting belongs, how to secure it, and where it must never be.
29 CFR 1926.25 · EN/ES
Sharp Deck Screws and Metal Shavings
Metal framing and deck work leave a snowfall of drill shavings, screw tips, and offcut slivers that find knees, palms, and eyes for weeks afterward. Screw points punch through pants at every kneel, shavings ride gloves into eyes, and swarf on the deck goes through boot soles. Small injuries, constant infections, and all preventable with cleanup and the right PPE. Today: the sharp litter problem.
29 CFR 1926.95 · 29 CFR 1926.25 · EN/ES
Insulation Fibers and Skin Irritation
Fiberglass and mineral wool fibers can bother your skin, eyes, and airways. OSHA requires the right protective gear wherever the work can hurt you through contact or breathing, and the company provides it at no cost to you. Every insulation product has a safety data sheet you can read on any shift. Today: dressing for fibers, working so they fly less, and getting them off you the right way.
29 CFR 1926.95 · 29 CFR 1910.1200 · EN/ES
Spray Foam and Isocyanate Exposure
Spray polyurethane foam is made when isocyanates, the A-side, react with the B-side in front of the gun. OSHA says the main effects of too much isocyanate exposure are occupational asthma and other lung problems, plus eye, nose, throat, and skin irritation. Today: who needs to be in the spray zone, and what everyone in it wears.
29 CFR 1910.1200 · 29 CFR 1910.134 · EN/ES
Paint and Coating Vapor Exposure
Solvent-based paints, epoxies, and sealers release vapors that do three things at once: make you dizzy and clumsy near edges and ladders, damage your nervous system over years of exposure, and build toward explosive concentrations in tight rooms. The painter feels fine right up until the headache, and the finish crew downwind gets a dose nobody planned. Today: ventilation, ignition, and the SDS.
29 CFR 1910.1200 · 29 CFR 1926.55 · 29 CFR 1926.152 · EN/ES
Hydraulic Pressure and Pinhole Leaks
Hydraulic systems run at high pressure, and a pinhole leak can shoot a stream you may not see. Running a hand along a hose to find a leak is the habit we are breaking today. OSHA requires buckets, blades, and dump bodies to be fully lowered or blocked during repairs. Today: finding leaks safely, releasing pressure, and treating any fluid hit on the skin as an emergency.
29 CFR 1926.600 · 29 CFR 1926.95 · EN/ES
Tire and Wheel Service on Equipment
A large equipment tire holds a lot of stored energy, and split-rim wheels are dangerous enough that OSHA requires a cage or rack to inflate them. Field tire work (plugging, airing up, changing on a trailer shoulder) is where shortcuts meet stored energy. Most of us should do exactly two things with big tires: check pressure with a clip-on chuck, and call the tire service. Today: what is our job and what is not.
29 CFR 1926.600 · EN/ES
Mud Season and Site Vehicle Recovery
Every spring the site turns to soup, and stuck equipment invites the most dangerous improvised rigging on the job: tow straps hooked to whatever looks strong, chains snatched at full throttle, and a crowd standing in the recoil path. A strap, chain, or shackle that lets go can fly back at people hard enough to badly hurt them. Today: recovery done like a lift plan, not a tug of war.
29 CFR 1926.600 · 29 CFR 1926.602 · EN/ES
Poison Ivy, Oak, and Sumac
Poison ivy oil (urushiol) is so strong that an amount smaller than a grain of salt gives most adults a rash. It can stay active on tools and gloves for years, and burning brush puts it in the smoke, where it can hurt your lungs. Site clearing, fence lines, and demo of overgrown lots are where crews get coated. Today: spotting it, dressing for it, and washing it off before it spreads.
29 CFR 1926.50 · 29 CFR 1926.95 · EN/ES
Insect Stings and Anaphylaxis on Site
Wasps nest in the exact places we work: eaves, attics, meter boxes, irrigation valve boxes, and brush piles. For workers allergic to venom, a sting can cause anaphylaxis, a life-threatening reaction that needs emergency care right away. NIOSH says workers with a history of severe reactions should carry an EpiPen. Today: nests, swarms, and the allergy plan.
29 CFR 1926.50 · EN/ES
Snake Awareness in Southern States
Rattlesnakes, copperheads, cottonmouths, and coral snakes live exactly where site work puts hands and feet: under material stacks, in crawl spaces, along slab edges, and in the cool of pipe and equipment left overnight. Reaching or stepping where you cannot see, or trying to kill a snake, puts you in strike range. Today: where they are, how not to meet one, and what a bite plan looks like.
