What federal OSHA is targeting in Connecticut
Connecticut has no state OSHA plan for private-sector work, so there is no state rule to read. What differs here is which hazards federal OSHA schedules inspections for, as set out in published emphasis directives.
Local Emphasis Program for the Seafood Processing Industry
CPL-04-00-026 · Boston Regional Office · effective June 1, 2023
“This instruction covers Region I and includes employers under Federal OSHA jurisdiction only.”
Seafood processing is targeted by NAICS 311710, 311711 and 311712, plus 424460 for fish and seafood merchant wholesalers, and the directive names the hazards it goes after: machine guarding, lockout/tagout, confined space, and the ammonia refrigeration systems that run the plant. It records why: exposure to ammonia and cooling system hazards produced three general duty clause violations in the region, one willful serious and two repeat serious, plus a hazard alert letter. Anhydrous ammonia is what ties this to hazard communication as well as to confined-space entry.

An employee was electrocuted on July 14, 2021, while repairing a portable water heater. OSHA found the Watertown manufacturer had no procedure to lock out the heater's power source during maintenance, had not given the employee lockout training, and did not check its energy control procedures periodically. It cited 48 safety and health violations and proposed $236,201.
U.S. Department of Labor / OSHA news release, January 14, 2022How Connecticut Enforces 29 CFR 1910.147
Connecticut operates an OSHA-approved state plan (Connecticut OSHA (CONN-OSHA)), but it covers only state and local government employees. Private-sector construction employers in Connecticut are inspected by federal OSHA, which enforces 29 CFR 1910.147 directly using the federal penalty maximums. So if you run a private construction company in Connecticut, Lockout/Tagout (LOTO) citations come from a federal Department of Labor compliance officer, not Connecticut OSHA (CONN-OSHA).
29 CFR 1910.147 is a general-industry standard and does not govern construction work. “This standard does not cover the following: (A) Construction and agriculture employment”. Branding a construction program “1910.147 compliant” cites the wrong standard. Unlike confined spaces, Part 1926 has no wholesale re-enactment of 1910.147: construction energy-control duties are spread across hazard-specific provisions, so no single construction equivalent is named here. A Connecticut contractor auditing against 29 CFR 1910.147 is auditing against the wrong standard. The citation an officer writes on a construction site will name the 1926 provision, not this one.

Lockout/Tagout (LOTO) FAQ for Connecticut
Which Connecticut industries most often face a Lockout/Tagout (LOTO) inspection?
Lockout/Tagout (LOTO) inspections reach general-industry employers in Connecticut, not the construction trades. Private-sector employers answer to federal OSHA (the Connecticut OSHA (CONN-OSHA) plan covers only public workers). A construction employer is not governed by 29 CFR 1910.147, and the construction-side duties on this subject are not concentrated in a single standard. Check your Part 1926 obligations instead.
How often is Lockout/Tagout (LOTO) cited in Connecticut?
29 CFR 1910.147 is enforced against general-industry employers in Connecticut, so the construction citation totals published for Connecticut (OSHA Frequently Cited Standards, NAICS 23) do not measure it. “This standard does not cover the following: (A) Construction and agriculture employment”. Branding a construction program “1910.147 compliant” cites the wrong standard. Unlike confined spaces, Part 1926 has no wholesale re-enactment of 1910.147: construction energy-control duties are spread across hazard-specific provisions, so no single construction equivalent is named here. A construction employer is not governed by 29 CFR 1910.147, and the construction-side duties on this subject are not concentrated in a single standard. Check your Part 1926 obligations instead.
Does OSHA require a written lockout/tagout program for Connecticut employers?
Yes. 29 CFR 1910.147 requires an energy control program with documented procedures for the equipment serviced, employee training, and a periodic inspection of each procedure at least annually. For private Connecticut employers, federal OSHA can cite the missing program, missing machine-specific steps, or the failure to train workers. In the PM Engineered case, OSHA cited a failure to develop lockout procedures for a water heater's power source and a failure to provide lockout training to the worker who died.
Who enforces lockout/tagout (1910.147) for a private Connecticut employer?
Federal OSHA. Connecticut's CONN-OSHA plan covers only public employees, so a compliance officer from OSHA's Boston region inspects and cites 1910.147 on private jobsites, at the federal penalty maximums.
Can I get free OSHA help in Connecticut without an inspection?
Yes. OSHA's On-Site Consultation Program in Connecticut is Connecticut Department of Labor/CONN-OSHA. OSHA describes it this way: "Primarily for smaller businesses, no-cost, confidential consultations help employers identify and address hazards and establish or improve safety and health programs." Consultations are separate from OSHA enforcement, and the employer commits to correcting serious hazards.
