What Maryland's own rule says
Maryland adopts the federal lockout/tagout standard by reference under the hazardous energy sources item of COMAR 09.12.31.01, and it did not rewrite the rule. That means the construction exclusion in 1910.147(a)(1)(ii)(A) applies here as it does federally. Maryland's adoption method is worth understanding on its own: rather than incorporating the CFR as it stands, the chapter lists individual Federal Register notices with the Maryland effective date for each, so the operative text is the sum of the notices actually listed.
29 CFR 1910.147 as adopted by COMAR 09.12.31.01, item IIThe duty matches the federal text. Only the citation number differs.

How Maryland Enforces 29 CFR 1910.147
Maryland runs an OSHA-approved State Plan administered by Maryland Occupational Safety and Health (MOSH), which covers private-sector construction. Its compliance officers enforce Maryland's own standards, which must be at least as effective as federal OSHA's and may go further. On this subject the rule is 29 CFR 1910.147 as adopted by COMAR 09.12.31.01, item II. Maryland Occupational Safety and Health (MOSH) issued no citations under 29 CFR 1910.147 in Maryland construction in FY2025. Maryland also sets its own civil-penalty maximums, equal to the federal baseline (see the penalty table below).
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 Maryland 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.

Free, confidential help: OSHA On-Site Consultation
In Maryland, the program is MOSH Consultation Services (Department of Labor, Licensing and Regulation). OSHA describes it as “Primarily for smaller businesses, no-cost, confidential consultations help employers identify and address hazards and establish or improve safety and health programs.” It is separate from OSHA enforcement; the employer commits to correcting serious hazards.

What are the penalties for 29 CFR 1910.147 violations in Maryland in 2026?
In Maryland, a serious violation of 29 CFR 1910.147 carries a maximum penalty of $16,550 per violation, and a willful or repeat violation up to $165,514.

Maryland sets its penalties under Labor and Employment §5-810, and the Commissioner of Labor and Industry adjusts them each July 15 on the CPI-U.

Which Maryland industries most often face a Lockout/Tagout (LOTO) inspection?
Lockout/Tagout (LOTO) inspections reach general-industry employers in Maryland, not the construction trades. Maryland Occupational Safety and Health (MOSH) inspects these employers directly and may apply requirements beyond the federal standard. 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 Maryland?
29 CFR 1910.147 is enforced against general-industry employers in Maryland, so the construction citation totals published for Maryland (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 MOSH require a written lockout/tagout program in Maryland?
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. In Maryland, MOSH, the state's own OSHA program, can cite the missing program, missing machine-specific steps, or the failure to isolate stored energy before service.
Who enforces lockout/tagout (1910.147) in Maryland?
MOSH, the Maryland Occupational Safety and Health program. Maryland runs a full OSHA-approved State Plan, so a state compliance officer inspects and cites 1910.147 on private jobsites.
Can I get free OSHA help in Maryland without an inspection?
Yes. OSHA's On-Site Consultation Program in Maryland is MOSH Consultation Services (Department of Labor, Licensing and Regulation). 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.
