OSHA PSM Penalty Exposure Estimator

Step 1 — Facility Size

Number of Employees

OSHA reduces penalties for smaller employers. Select the size bracket that best represents your establishment (not the entire company).

1–10 employees 40% reduction

11–25 employees 20% reduction

26–250 employees 10% reduction

250+ employees No reduction

Step 2 — Add Citations

Citation Items

Add each citation type you are modeling. Use actual or worst-case counts per violation instance.

Citation Type	# of Items	Max per Item	Subtotal

Step 3 — Adjustment Factors

Penalty Reduction Adjustments

OSHA may apply additional reductions for demonstrated good faith effort and clean citation history. These do not apply to willful citations.

Good Faith Reduction: 0%

Active safety programs, comprehensive PSM documentation, and demonstrated compliance efforts can earn up to 25% reduction on serious citations.

History Reduction: 0%

No prior citations in the past 3 years earns a 10% reduction. Prior violations may increase penalties by up to 10%.

Understanding OSHA PSM Penalties

Current penalty maximums, reduction factors, and what real PSM enforcement actions look like.

Willful

$16,131–$161,323

Issued when OSHA finds an employer knew of a hazard and made no effort to correct it, or acted with plain indifference to employee safety. PSM willful citations are common in cases with incomplete PHAs, missing MOC documentation, or repeated prior violations. No good faith reduction applies.

Repeat

up to $161,323

Issued when a substantially similar violation existed within the past 5 years. OSHA compares citations across any facility under the same corporate entity — a citation at a sister plant counts. PSM repeat citations are frequently pursued in multi-site chemical companies.

Serious

up to $16,131

The most common PSM citation type. Issued when there is a substantial probability the hazard could cause death or serious physical harm. OSHA uses a "gravity" multiplier based on actual probability and severity — the adjusted penalty may be well below the maximum, but willful and repeat multipliers can drive it back up.

Other-Than-Serious

up to $16,131

Rare in PSM enforcement. Reserved for violations that have a direct relationship to workplace safety but would not likely cause death or serious injury. PSM paperwork deficiencies sometimes fall here, but OSHA typically classifies incomplete PHA or MOC documentation as serious.

Failure to Abate

up to $16,131/day

Issued when a previously cited violation has not been corrected by the abatement deadline. FTA penalties accrue per day, making this the fastest path to catastrophic penalty exposure. A single serious citation left uncorrected for 30 days equals $483,930 in FTA penalties alone.

Real PSM Enforcement Numbers

$268K Average penalty package in PSM-focused OSHA enforcement actions (2019–2024)

$1M+ Penalty exposure in major PSM cases involving willful violations or fatalities

12–18 mo Typical duration of a comprehensive OSHA PSM inspection and citation process

100+ PSM-related citations issued annually — PHA, MOC, and mechanical integrity top the list

OSHA Penalty Reduction Factors

Factor	Criteria	Reduction	Applies to Willful?
Size	1–10 employees	Up to 40%	No
Size	11–25 employees	Up to 20%	No
Size	26–250 employees	Up to 10%	No
Good Faith	Documented safety program, comprehensive PSM compliance, proactive corrective action	Up to 25%	No
History	No prior OSHA violations in past 3 years	10%	No
History (negative)	Prior violations in past 3 years	Up to +10%	No
Gravity	Based on probability and severity — OSHA discretion	10–100% of base	No
Informal Settlement	Agreeing to abatement and correction without formal contest	Negotiated, often 30–50%	Sometimes
