NAICS 213112 Compliance Finder

Oilfield service contractors operating under NAICS 213112 (Support Activities for Oil and Gas Operations, formerly SIC 1389) must comply with specific OSHA General Industry standards based on their service type. This free tool identifies which OSHA 1910 standards apply to your operations, whether you run hydrovac services, wireline operations, workover rigs, frac crews, coil tubing, or hot shot trucking. Understanding your compliance requirements is essential for avoiding citations, especially under OSHA's Multi-Employer Worksite Rule.

About NAICS 213112

NAICS 213112 (Support Activities for Oil and Gas Operations) replaced the legacy SIC code 1389. This classification includes oil and gas well services performed on a contract basis, such as well drilling support, well completion, reworking, and other well servicing activities. The BLS uses this code for industry-specific injury/illness rate benchmarking.

Most-Cited OSHA Standards for Oilfield Contractors

These standards appear in the majority of oilfield OSHA citations. Ensure you have documented compliance programs for each.

1910.146

Permit-Required Confined Spaces

Tanks, vessels, and enclosed spaces require written programs, permits, atmospheric testing, and rescue procedures. One of the most frequently cited standards in oilfield fatalities.

1910.134

Respiratory Protection

Required where employees may be exposed to harmful atmospheres including H2S. Mandates written programs, fit testing, medical evaluation, and training.

1910.147

Lockout/Tagout (LOTO)

Controls hazardous energy during servicing and maintenance. Requires written procedures, training, and periodic inspections. Critical for wellhead and equipment work.

1910.1200

Hazard Communication (HazCom)

"Right to Know" standard requiring SDS access, labeling, and training on chemical hazards. Applies to virtually all oilfield operations handling chemicals.

Understanding the Multi-Employer Worksite Rule

As a contractor working on operator sites, you can be cited for hazards you didn't create. Here's how OSHA categorizes employer responsibility:

Creating Employer

You created the hazard through your work activities. You must correct the hazard even if your own employees aren't exposed.

Example: Your crew leaves an unguarded floor opening. You're liable even if only another contractor's workers are at risk.

Exposing Employer

Your employees are exposed to a hazard. You must protect them even if another employer created the hazard.

Example: The operator has inadequate fall protection. You must either fix it, get it fixed, or remove your employees.

Correcting Employer

You're responsible for correcting hazards (often the general contractor or operator). Must exercise reasonable care in correction.

Example: As site supervisor, you're responsible for ensuring all contractors maintain compliance.

Controlling Employer

You have general supervisory authority over the worksite. Must exercise reasonable care to detect and correct violations.

Example: The operator or prime contractor with authority to stop work for safety violations.

Contractor Best Practice

Document every hazard you identify and every request you make for correction. If the operator refuses to correct a hazard exposing your employees, you have limited options: protect your workers yourself, remove them from exposure, or stop work. "The operator said it was fine" is not an OSHA defense.
