Weekly digest #156: OSHA updates

OSHA's 2026 Lockout/Tagout Enforcement Push

OSHA bumped LOTO citations to its top-five most-cited list again this quarter. Region offices are running targeted inspections on commercial and industrial sites, and electrical contractors are showing up in the data. If your crew is opening panels on energized gear without documented procedures, you are exposed.

The standard has not changed. 29 CFR 1910.147 still requires written, equipment-specific procedures, annual inspections, and individual locks per worker. What changed is enforcement. Compliance officers are pulling procedure binders on arrival and asking apprentices to walk through the steps. Memorized generalities will not pass.

NFPA 70E aligns here through Article 120, which mirrors LOTO requirements for electrical work and adds the establishment of an electrically safe work condition. NEC 110.16(B) covers the arc-flash labeling that supports your energized work permit decisions.

Updated Heat Illness Rules Hit Outdoor Crews

The federal heat standard moved out of proposed-rule status in early 2026, and several states already have stricter local rules in force. Service entrance work, parking lot lighting retrofits, and rooftop solar tie-ins all fall under it. Indoor work above 80F also triggers monitoring requirements.

The rule requires water access, shaded rest areas, acclimatization plans for new workers, and high-heat procedures above 90F. For electrical crews wearing arc-rated PPE, the heat load adds up fast. CAT 2 layered systems can push the wearer's effective temperature 10 to 15 degrees above ambient.

Pre-stage water and shade at the truck before the first pull. Once you are committed to a conduit run in 95 degree sun, no one wants to walk back across the lot for hydration.

Fall Protection at 4 Feet, Not 6

OSHA general industry rules under 1910 Subpart D require fall protection at 4 feet. Construction under 1926 still uses 6 feet. The distinction matters because service work, maintenance, and tenant improvements often fall under general industry even when they look like construction.

If you are pulling cable above a drop ceiling on a finished commercial space, that is general industry. Stepladder work on a 6 foot ladder reaching into the ceiling cavity puts you at the threshold. Document which standard applies on your JHA before the work starts.

• General industry (1910): 4 foot trigger height for guardrails, nets, or personal fall arrest
• Construction (1926): 6 foot trigger, with leading edge and hoist area exceptions
• Scaffolds: 10 feet across both standards
• Steel erection: 15 feet, but connectors get specific provisions

Silica Exposure on Concrete Penetrations

Core drilling for service entrance conduit, chasing slabs for floor boxes, and cutting masonry for EMT runs all generate respirable crystalline silica. OSHA's Table 1 under 1926.1153 lists specified controls for common tasks, and inspectors are checking for water suppression or HEPA shrouds on the saw or drill.

The 8 hour PEL is 50 micrograms per cubic meter. A dry cut on a hand held grinder blows past that in minutes. If you are using Table 1 controls properly, you do not need to do exposure monitoring. Skip the controls and you owe a written exposure assessment plus medical surveillance for anyone over the action level for 30 days a year.

Pair this with NEC 300.5 burial depth requirements when you are trenching and coring for underground feeders. The exposure window stacks fast on a single service upgrade.

Electrical PPE Inspection Documentation

OSHA 1910.137 and NFPA 70E Article 130.7 both require inspection of insulating gloves, sleeves, blankets, and live line tools. The retest intervals have not shifted, but documentation expectations have. Inspectors want to see dated stamps on the gloves and a log tying serial numbers to test dates.

Write the in service date on the cuff of new rubber gloves with a paint pen the day they come out of the bag. The clock starts on first issue, not on receipt at the warehouse.

1. Class 00 and 0 gloves: retest every 6 months once issued
2. Class 1, 2, 3, 4 gloves: retest every 12 months
3. Visual and air test before every use, every time
4. Bag the gloves between uses, store flat, away from ozone sources and direct sun

Recordable Injury Reporting Window

The 24 hour reporting window for inpatient hospitalizations, amputations, and eye loss is now firmly enforced through OSHA's online portal. Fatalities still trigger an 8 hour window. Form 300A posting from February through April should already be down by now if your fiscal year aligns with calendar year.

Arc flash burns that result in hospitalization count, even if the worker is released the same day after observation. If the admission paperwork shows inpatient status, the clock started. Get the report filed and document the energy source, the task, and the PPE in use at the time of the incident.

Cross reference your incident with NEC 110.16(B) labeling and your most recent arc flash study. If the incident energy at the working distance exceeded the PPE rating in use, that is a finding you want surfaced internally before a compliance officer surfaces it for you.
