WISHA vs. Federal OSHA: What Washington Dental Practices Need to Know

Operating a dental practice in Washington means following not just federal OSHA rules, but also Washington’s own safety standards under WISHA. While both systems share the same goal—keeping workers safe—WISHA adds state-specific rules and stricter enforcement expectations that every dental practice must understand.

Here’s what sets Washington apart and how to keep your dental team compliant.

WISHA: Washington’s State-Plan OSHA

The Washington Industrial Safety and Health Act (WISHA) is enforced by the Washington State Department of Labor & Industries (L&I), Division of Occupational Safety and Health (DOSH).WISHA is a state-plan OSHA, meaning it adopts federal OSHA standards and adds state-specific rules.

• Legal authority: RCW 49.17

• Core rules for all workplaces: WAC 296-800

Written Safety Programs Are Mandatory

While federal OSHA requires written safety plans for certain hazards, WISHA requires all employers to have an overarching written Accident Prevention Program (APP).

Your dental practice’s APP must be:

• Tailored to your workplace

• Include orientation for new employees

• Include ongoing safety meetings

• Reviewed and updated regularly

Reference: WAC 296-800-140

You must also have:

• Bloodborne Pathogens Exposure Control Plan — WAC 296-823

• Hazard Communication Program (chemical safety) — WAC 296-901

Federal OSHA requires these plans too, but Washington expects them to be site-specific and implemented in daily practice, not just paperwork on a shelf.

Training Must Be Interactive and Documented

WISHA requires interactive safety training—not just videos or handouts—and proof of completion for all staff.Key expectations for dental offices include:

• Bloodborne Pathogens: initial and annual training

• Hazard Communication: initial and annual refreshers

• PPE, emergency response, and sharps safety: included in the APP

• Documented training records with dates, topics, and attendees

References:

• WAC 296-823-12005 (BBP Training)

• WAC 296-901-14016 (HazCom Training)

Federal OSHA requires similar training (29 CFR 1910.1030, 1910.1200), but does not require annual HazCom refreshers—Washington does in practice.

Hazard Communication Rules

Washington enforces the same GHS-aligned chemical labeling and Safety Data Sheet (SDS) requirements as OSHA, but with stronger expectations for customization and access:

• Maintain a current inventory of all office chemicals

• Label all containers, including secondary bottles

• Ensure SDS are accessible to staff at all times

• Train staff on chemical hazards and emergency actions

Reference: WAC 296-901

Personal Protective Equipment (PPE)

Both OSHA and WISHA require PPE to be provided at no cost, but Washington closely enforces documentation of PPE hazard assessments and training.

Dental offices must:

• Evaluate tasks for PPE needs

• Provide gloves, masks, protective eyewear, gowns/jackets

• Provide puncture-resistant utility gloves for instrument processing

• Document staff PPE training

References:

• WAC 296-800-160

• 29 CFR 1910 Subpart I

Recordkeeping and Reporting

• Dental offices (NAICS 6212) are exempt from routine injury/illness logs, but must still:

  • Report fatalities within 8 hours

  • Report hospitalizations, amputations, or loss of an eye within 24 hours

• Must retain:

  • Hepatitis B vaccine offer/declination forms

  • Training sign-ins

  • Sterilizer and eyewash testing logs

  • Annual plan reviews

References:

• WAC 296-27

• 29 CFR Part 1904

Bottom Line for Washington Dental Practices

If you run a dental office in Washington, you are regulated by WISHA, not federal OSHA directly.That means you must meet all federal rules plus Washington’s additional requirements for:

• Written safety programs (APP, BBP, HazCom)

• Annual interactive training

• Documented safety meetings

• Strong recordkeeping and documentation practices

By maintaining up-to-date, site-specific safety programs and thoroughly documenting training, your dental team can stay compliant, avoid costly citations, and most importantly—keep everyone safe and healthy at work.
