The talks below match the hazards hvac / mechanical crews actually face: rooftop work, brazing / hot work, refrigerant handling, confined spaces, electrical lockout. Every talk is free, comes in English and Spanish, and includes a printable sign-in sheet so the meeting is documented.
HVAC / Mechanical-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
Lockout / Tagout: Controlling Energized Circuits
Lockout/tagout was the fourth most cited OSHA standard in fiscal year 2025. A breaker someone flips back on can kill the person working on the circuit. Lockout tagout is how we make sure the circuit you are working on stays dead until you say otherwise. Nobody trusts a switch position or a coworker's word. We trust locks, tags, and our own meter.
29 CFR 1926.417 · 29 CFR 1910.147 · EN/ES
Hot Work and Torch Safety
Torch-down roofing, brazing, and cutting all leave something behind you cannot see: heat soaked into the deck, smoldering insulation, a spark in the wall cavity. A fire can start after the torch is off. The fire watch is not a formality; it is the job.
29 CFR 1926.352 · 29 CFR 1926.354 · 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
Compressed Gas Cylinder Safety
A knocked-over cylinder can snap its valve and release gas under high pressure. OSHA requires cylinders kept upright and secured, with valve caps on, and fuel gas used valve end up. Cylinders are routine cargo on plumbing, HVAC, and roofing jobs, and routine is where the shortcuts creep in.
29 CFR 1926.350 · 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
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
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
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.
