Exposed to Hazardous Conditions
Work context · O*NET
Exposed to Hazardous Conditions is a work-context dimension in the O*NET database — one of the standardized conditions O*NET uses to describe the environment a job is done in , grouped under Physical Work Conditions. O*NET defines it by asking workers: "How often does this job require exposure to hazardous conditions?." It is rated for 894 occupations, which average 2.02 out of 5 (low relative to other context dimensions).
How it's measured
O*NET rates each occupation on this dimension on a 1–5 context-importance scale (the CX scale), where higher means the condition is a more frequent or more central part of the work. The figures on this page are those occupation-level ratings — a description of working conditions as workers report them, not a judgment about pay, difficulty, or whether a job is "good."
| Economy-wide average | 2.02 / 5 | Mean across all 894 rated occupations |
| Range across occupations | 1.00–4.94 | Lowest to highest occupation rating (spread 3.94) |
| Intensity vs. other dimensions | 25th pct | Where this dimension's average ranks among all O*NET work-context dimensions |
Occupations where it's highest
The occupations that rate this condition strongest on the 1–5 scale.
Occupations where it's lowest
The occupations that rate this condition weakest — where it is rarely part of the work.

How AI is used by roles where exposed to hazardous conditions is central
A working condition is not itself "being automated" — but we can look at the occupations where it is most central and ask how those people actually use AI. This rolls the Anthropic Economic Index per-role signal up across the roles that rate this condition 3 or higher (CX-rating-weighted). 43.3% of the 171 occupations where this condition is present carry observed AI-usage data (74 roles).
Across those roles, 34.2% of AI conversations are people working with AI and 29.0% hand a task to AI , with an average autonomy of 3.59 / 5.
| Collaboration pattern | Share | What it means |
|---|---|---|
| directive | 23.8% | AI does it; you give the instruction |
| learning | 21.4% | you ask AI to explain or teach |
| task iteration | 11.5% | you and AI go back and forth |
| feedback loop | 5.2% | AI does it, then adjusts from your feedback |
| validation | 1.3% | you do it; AI checks your work |
Roles behind this signal
The occupations where this condition is most central and that also have the most AEI data. "Works with AI" is the role's share of conversations that augment rather than automate.
| Occupation | Condition (1–5) | Works with AI | Autonomy |
|---|---|---|---|
| Chemistry Teachers, Postsecondary | 3.3 | 66.0% | 4.0/5 |
| Chemists | 3.6 | 61.8% | 4.0/5 |
| Chemical Technicians | 4.5 | 53.9% | 4.0/5 |
| Molecular and Cellular Biologists | 3.0 | 57.2% | 3.8/5 |
| Biochemists and Biophysicists | 3.1 | 64.5% | 4.0/5 |
| Microbiologists | 3.5 | 56.2% | 4.0/5 |
| Materials Scientists | 3.0 | 49.0% | 3.0/5 |
| First-Line Supervisors of Housekeeping and Janitorial Workers | 3.3 | 48.5% | 4.0/5 |
| Geneticists | 3.0 | 53.4% | 4.0/5 |
| Nanosystems Engineers | 3.4 | 63.0% | 4.0/5 |
| Industrial Machinery Mechanics | 3.4 | 22.8% | 4.0/5 |
| Solar Photovoltaic Installers | 4.3 | 47.2% | 4.0/5 |
Source: Anthropic Economic Index (2026-01-15-v4-plus-2025-03-27-v2) over a sample of Claude.ai Free and Pro conversations — not all AI tools and not the whole workforce. This is a role-weighted projection from AEI-linked occupations where this condition is central, not a direct measurement of AI use for the condition itself. Shares are weighted by how central the condition is to each role; some conversations are left unclassified by Anthropic's taxonomy, so shares need not sum to 100.
