What Is an Other-Than-Serious Violation
An other-than-serious violation is a workplace safety or health violation where there is a direct relationship to job safety but the hazard would not likely cause death or permanent physical harm. OSHA uses this classification when a violation creates risk but falls below the threshold of a serious violation. The distinction matters because it determines penalty amounts, corrective timelines, and how aggressively regulators pursue enforcement.
OSHA Classification Standards
OSHA's penalty structure reflects the severity tier. As of 2024, an other-than-serious violation carries a maximum penalty of $10,761 per violation, compared to $16,131 for serious violations. The agency determines classification by asking whether exposure to the hazard would likely result in an injury or illness but not one that would probably result in death or permanent total disability. Examples include inadequate machine guarding that could cause a laceration, improper storage of non-hazardous materials creating a trip hazard, or missing guardrails on a platform under 6 feet where a fall would cause bruising rather than fractures.
How This Differs From Serious Violations
The core difference hinges on injury severity. A serious violation assumes the hazard creates substantial probability of death or permanent disability. A fall from 15 feet would be serious; a trip hazard in a walkway would not. In home safety audits, this matters when assessing fire escape routes (serious if blocked) versus clutter on stairs (other-than-serious). Chemical handling violations become serious when they involve toxic substances at high concentrations in confined spaces; they become other-than-serious if the same chemical is present but in quantities or conditions that would cause minor exposure.
Real-World Examples
- Workplace: Missing or worn step on a 4-foot ladder, inadequate labeling on cleaning supply containers, or broken handrails on a stairwell with a 5-foot drop
- Emergency preparedness: Exit signs that are dim but still visible, or emergency contact lists not posted in the break room
- Fire safety: Blocked access to fire extinguishers that still function and are accessible from another route, or extension cords used in ways that create minor shock risk rather than fire
- Chemical storage: Improper organization of non-hazardous cleaning supplies, or incompatible products stored adjacent to each other without immediate risk of reaction
Corrective Action Timeline
While OSHA can issue citations immediately, businesses typically receive 30 days to correct other-than-serious violations. This contrasts with imminent danger situations requiring immediate correction. During a safety audit, auditors document other-than-serious violations in writing and provide a reasonable timeline. Homeowners addressing similar issues might prioritize these after serious hazards but still within a month to demonstrate good-faith compliance.
Citation and Documentation
When OSHA issues a citation for an other-than-serious violation, the paperwork specifies the regulatory standard violated, the location, and the corrective deadline. Safety managers should photograph violations, document when corrections occur, and retain records for three years. This demonstrates due diligence if a repeat violation is cited or if a worker files a complaint.
Common Questions
- Can an other-than-serious violation become serious? Yes, if the same hazard exists in a more dangerous form. A missing step on a 4-foot ladder is other-than-serious; the same missing step on a 20-foot ladder becomes serious because the fall distance increases injury severity.
- What happens if I don't correct an other-than-serious violation within the timeframe? OSHA can issue a repeat violation citation with a higher penalty. Multiple uncorrected citations also signal negligence in your safety program during future audits.
- How do I dispute an other-than-serious classification? File a notice of contest with OSHA within 15 days of the citation. You can argue the violation lacks a direct safety relationship or that the injury outcome would not occur under normal workplace conditions.
