OSHA Top 10 Citations: 2011-2020

OSHA Top 10 2011 - 2020

2020 OSHA Top Citations – Same as 2019

OSHA announced it’s preliminary findings for the most cited standards for 2020, as revealed in a recent webinar with Safety+Health magazine. Not surprisingly, there were no changes from the 2019 list, with Fall Protection ranking Number 1 for the 10th straight year. Other notable changes were Respiratory Protection (1910.134) jumping to Number 3 from Number 5, Ladders (1926.1053) moving from Number 6 to Number 5, and PPE Eye & Face Protection (1926.102) moving from Number 10 to Number 9.

2020 OSHA Top 10

  1. Fall Protection – General Requirements (1926.501): 5,424 violations
  2. Hazard Communication (1910.1200): 3,199
  3. Respiratory Protection (1910.134): 2,649
  4. Scaffolding (1926.451): 2,538
  5. Ladders (1926.1053): 2,129
  6. Control of Hazardous Energy – Lockout / Tagout (1910.147): 2,065
  7. Powered Industrial Trucks (PITs) (1910.178): 1,932
  8. Fall Protection – Training Requirements (1926.503): 1,621
  9. Personal Protective (PPE) and Life Saving Equipment – Eye and Face Protection (1926.102): 1,369 
  10. Machine Guarding (1910.212): 1,313

Little Change over a 10 Year Period

As you can see from the graphic above (larger version here), only 12 standards have reached the Top 10 over the last decade, with the only changes being:

  • Added:
    • Fall Protection, Training (1926.503)
    • PPE, Eye & Face Protection (1926.102
  • Removed:
    • Electrical, Wiring Methods (1910.305)
    • Electrical, General (1910.303)

Inspections Down in 2020

Inspections by OSHA were down in 2020, primarily due to the impact of the COVID-19 pandemic, and nearly 39% below 2015 levels.

Free eTool: Industrial Hygiene Exposure Assessment Characterization

industrial hygiene exposure assessment decision matrix

Anticipate, Identify, Recognize

When starting an occupational exposure assessment, the first step a practicing industrial hygienist must do is be able to anticipate, identify, and/or recognize workplace hazards so that stressors that may impact employee health can be evaluated later in the assessment. Understanding the workplace, how chemical and physical agents are generated and the existing control measures (e.g. engineering controls) in place, help the industrial hygienist to develop an effective plan for evaluating risks.

IHEST – Industrial Hygiene Exposure Scenario Tool

AIHA has released the free IHEST (Industrial Hygiene Exposure Scenario Tool) which helps an industrial hygienist to identify and capture basic exposure potential data, for the purpose of improving evaluation accuracy in the assessment process. The tool includes prompts for:

  • Process Overview
  • Task Description
  • Exposure Controls
  • Similar Exposure Groups
  • Employee Tasks
  • Ventilation
  • Room layout
  • Airborne concentrations
  • Dermal exposures, and
  • Noise exposures

Statistical Analysis of Health & Safety Data – IHSTAT

Are you looking for statistical analysis of health and safety data (e.g. number of measured occupational exposures that exceed established OELS)? Take a look at’s post on IHSTAT, where you can download AIHA’s excel worksheet that can perform some basic statistics for you.

Statistical Analyses for Occupational Exposure Results

NIOSH released a guide, Occupational Exposure Sampling Strategy Manual (1977), that describes statistical analyses for occupational exposure results in a clear and concise manner. Included are discussions and examples on:

  • Confidence Limits (CL’s)
  • CL’s and Compliance / Non-compliance Classifications
  • Statistics and Classifications for: full period sampling, partial period sampling, consecutive sampling, grab sampling, comparison to ceiling standards, and more.

If you are looking for a (free) guide that details “real world” occupational exposure statistical analyses, download NIOSH’s guide HERE ().

IHSTAT – Statistical Analysis of Health & Safety Data


IHSTAT is a excel worksheet that enables statistical analyses of occupational hygiene measurement data and compliance testing (with occupational exposure limits).  IHSTAT was developed by AIHA (American Industrial Hygiene Association).

  1. Determines whether samples are normally distributed or log normally distributed.
    • Normal distribution – data that clusters around a mean/average
    • Log Normal distribution – the logarithm of data is normally distributed
  2. Determines percentage of samples that exceed the occupational exposure limit.
