OSHA Requirements for New Hampshire Contractors
Federal Occupational Safety and Health Administration standards apply to construction employers and contractors operating throughout New Hampshire, governing worksite safety conditions, hazard communication, personal protective equipment, fall protection, and recordkeeping. New Hampshire does not operate a state-plan OSHA program, meaning federal OSHA has direct enforcement jurisdiction over private-sector employers in the state. Violations can carry penalties ranging from $16,131 per serious violation up to $161,323 per willful or repeated violation (OSHA Penalty Adjustments, 29 CFR Part 1903). Understanding how these requirements interact with New Hampshire contractor safety regulations is essential for any contractor operating in the state.
Definition and scope
OSHA requirements for New Hampshire contractors are grounded in the federal Occupational Safety and Health Act of 1970 (29 U.S.C. § 651 et seq.), which established the general duty of employers to provide a workplace free from recognized hazards likely to cause serious injury or death. For contractors, the primary regulatory framework is found in 29 CFR Part 1926, which covers Safety and Health Regulations for Construction, and 29 CFR Part 1910, which covers General Industry standards applicable where construction-specific rules do not address a specific condition.
Scope of federal OSHA coverage in New Hampshire:
- Applies to all private-sector construction employers with at least 1 employee
- Covers general contractors, subcontractors, and specialty trade contractors on multi-employer worksites
- Applies to temporary workers and staffing agency placements on construction sites
- Does not apply to self-employed individuals with no employees
- Does not apply to state and local government employers (New Hampshire has separate public-employee protections under RSA 281-A)
Scope limitations: This page addresses federal OSHA obligations for private-sector contractors in New Hampshire. State and municipal public works employer obligations, which fall outside federal OSHA's private-sector jurisdiction, are not covered here. Contractors working on federally funded projects may have additional requirements under the Davis-Bacon Act or other federal contract provisions, which are addressed separately under New Hampshire public works contractor requirements.
How it works
Federal OSHA enforces construction safety in New Hampshire through the OSHA Area Office in Concord, NH. Enforcement proceeds through four primary mechanisms: programmed inspections (targeting high-hazard industries), unprogrammed inspections (responding to fatalities, catastrophes, and complaints), consultation services (voluntary, penalty-free), and recordkeeping audits.
Key regulatory standards under 29 CFR Part 1926 applicable to New Hampshire contractors:
- Subpart E – Personal Protective Equipment (§1926.95–.107): Requires employers to assess hazards and provide appropriate PPE at no cost to workers.
- Subpart M – Fall Protection (§1926.500–.503): Mandates fall protection systems at heights of 6 feet or more in construction; leading cause of construction fatalities nationally (OSHA Fall Protection).
- Subpart P – Excavations (§1926.650–.652): Requires protective systems for trenches 5 feet or deeper; directly relevant to New Hampshire excavation contractor services.
- Subpart Q – Concrete and Masonry (§1926.700–.706): Covers shoring, formwork, and precast concrete operations.
- Subpart R – Steel Erection (§1926.750–.761): Applies to structural steel assembly on commercial and industrial projects.
- Subpart Z – Toxic and Hazardous Substances (§1926.1100–.1153): Includes lead (§1926.62) and asbestos (§1926.1101) standards critical for renovation contractors.
- Hazard Communication (§1910.1200): Requires Safety Data Sheets (SDS) and employee training on chemical hazards; applies via the General Industry standard where no construction-specific rule exists.
Recordkeeping (29 CFR Part 1904): Employers with 11 or more employees in construction must maintain OSHA Form 300 (Log of Work-Related Injuries and Illnesses), Form 300A (Summary), and Form 301 (Incident Report). The annual summary must be posted from February 1 through April 30 each year.
Multi-employer worksites: OSHA's multi-employer citation policy holds that both creating employers (who generate a hazard) and controlling employers (general contractors who have authority to correct hazards) can be cited. General contractors are not automatically liable for all subcontractor violations, but are accountable where they have or should have supervisory authority over safety conditions.
Common scenarios
Residential roofing contractors in New Hampshire frequently face citations under Subpart M fall protection standards. Residential roofing operations have a specific exception under §1926.502(b) for certain steep-pitch roofs, but this exception requires documented proof that conventional fall protection is infeasible — not simply inconvenient. Roofing contractors are addressed within the broader New Hampshire roofing contractor services sector.
Electrical contractors must comply with both 29 CFR Part 1926 Subpart K (Electrical) and, where applicable, the National Electrical Safety Code standards. Lockout/tagout procedures under §1910.147 apply to electrical work on existing equipment. See New Hampshire electrical contractor services for how licensing intersects with these safety obligations.
HVAC and plumbing contractors working in confined spaces must comply with 29 CFR §1926.1200–.1213 (Confined Spaces in Construction), which became effective in 2015 and introduced a permit-required confined space classification distinct from the General Industry standard.
Renovation and demolition contractors handling pre-1980 structures must conduct asbestos and lead assessments before disturbing suspect materials. The asbestos standard (§1926.1101) classifies work into Class I through Class IV, with Class I (removal of thermal system insulation) carrying the most stringent requirements.
Decision boundaries
Federal OSHA vs. no OSHA jurisdiction:
| Employer type | OSHA jurisdiction |
|---|---|
| Private contractor, 1+ employees | Federal OSHA (29 CFR 1926) |
| Self-employed, no employees | No federal OSHA jurisdiction |
| State/municipal employer | Outside federal OSHA; NH RSA 281-A applies |
| Federal contractor on federal property | Federal OSHA plus potential agency-specific rules |
Part 1926 vs. Part 1910: When a contractor performs work not specifically addressed in 29 CFR Part 1926, OSHA applies the General Industry standard in Part 1910 by default. This distinction matters for equipment operation, chemical handling, and noise exposure assessments.
Recordkeeping threshold: Employers with 10 or fewer employees are partially exempt from routine OSHA injury and illness recordkeeping (though they must still report fatalities and severe injuries) (29 CFR §1904.1). This threshold affects a significant portion of the small contractor market in New Hampshire.
Inspection triggers: OSHA prioritizes inspections in the following order: (1) imminent danger, (2) fatalities and catastrophes, (3) complaints and referrals, (4) follow-up inspections, (5) programmed inspections of high-hazard industries. Construction consistently ranks among the highest-hazard sectors nationally, meaning New Hampshire construction employers are subject to higher programmed inspection frequency than most general industry employers.
Contractors should also review New Hampshire contractor insurance requirements and New Hampshire contractor license requirements to understand how OSHA compliance intersects with the full regulatory picture for operating legally in the state.
