Yes — steamfitting is a dangerous job by the federal injury numbers.
Plumbers, pipefitters, and steamfitters logged 144.5 days-away-from-work cases per 10,000 full-time workers in 2023-2024, against 86.6 for all occupations, and the injuries BLS calls common — cuts from sharp tools, burns from hot pipes and soldering equipment, falls from ladders — are injuries of that combined trade's ordinary work.
Below: the data, the pressure and height exposures, and the safety training.
Short answer: is being a steamfitter dangerous?
The federal number comes from the Bureau of Labor Statistics' Survey of Occupational Injuries and Illnesses.
In 2023-2024, plumbers, pipefitters, and steamfitters — the single federal occupation code steamfitters are counted inside — recorded 144.5 days-away-from-work cases per 10,000 full-time workers in private industry, against 86.6 for all occupations.
Their DART rate (days away, restricted, or transferred) was 211.7 per 10,000 full-time workers.
One caveat shapes every statistic on this page: the survey publishes no steamfitter-only rate.
O*NET merged the old Plumbers code and the old Pipe Fitters and Steamfitters code into one occupation, 47-2152.00 Plumbers, Pipefitters, and Steamfitters, and the old codes are no longer in use.
BLS's injury survey counts that combined occupation, so 144.5 is a pipe-trades number, not a steamfitter slice.
What the number says is direction: the trade's combined injury rate runs well above the rate for all occupations.
How it sits against other trades, one by one, is the cross-trade question our guide to plumbing hazards answers from the same BLS table; this page stays with the steamfitter's own exposures — the pressure systems, the tight spaces, the height work — and the safety training built around them.
For the role as a whole — the systems, the settings, the apprenticeship, the pay — the steamfitter career guide covers it end to end.
Steam and pressure hazards
What sets steamfitting apart, in BLS's description, is the material in the pipe.
BLS describes pipefitters' and steamfitters' piping as pipes that may carry chemicals, acids, and gases, and it draws the steamfitter boundary at pressure: steamfitters specialize in systems designed for the flow of liquids or gases at high pressure.
The United Association describes the same work in shop terms — fabricating, installing, maintaining, and repairing high-pressure systems that move steam, hot water, and other industrial fluids, with welding, rigging, and hydrostatic and pneumatic testing among the work.
Against that backdrop, BLS's Occupational Outlook Handbook — whose injury list covers plumbers, pipefitters, and steamfitters together — names the common injuries: "Common injuries include cuts from sharp tools, burns from hot pipes and soldering equipment, and falls from ladders."
Each injury on BLS's list is paired, in the same sentence, with its instrument: sharp tools, hot pipes and soldering equipment, ladders.
BLS ranks none of them, and neither does this page.
What our research does not hold is a breakdown of the injury rate by hazard.
No verified figure separates steam burns from soldering burns, or counts pressure-release incidents on their own — BLS's published list is the boundary of what this page can name, and naming beyond it would be guessing.
The absence of a figure is not the absence of a hazard; it is the absence of a number we can stand behind.
The rules for a specific job come from the employer and OSHA
Confined spaces and heights
The O*NET worker survey measures where the working day is spent, and its numbers are exposure frequencies, not injury rates.
Among plumbers, pipefitters, and steamfitters, 21% report exposure to cramped work spaces or awkward positions every day, and another 43% once a week or more but not every day; 25% are exposed to high places every day.
Those survey categories are O*NET's.
OSHA's construction standards write rules for separate settings, and two of them put duties on the employer wherever work falls under them.
One is confined spaces: before work begins, the employer must ensure a competent person identifies all confined spaces in which employees may work, and identifies each space that is a permit space (29 CFR 1926.1203(a)).
For height work, OSHA's construction fall-protection standard draws the line at six feet: workers on a surface with an unprotected side or edge 6 feet (1.8 m) or more above a lower level must be protected from falling by guardrail systems, safety net systems, or personal fall arrest systems (29 CFR 1926.501(b)(1)).
BLS separately names falls from ladders among common injuries for plumbers, pipefitters, and steamfitters.
What this section cannot do is put a frequency on confined-space entry for the trade.
Cramped or awkward positions are the O*NET survey's category, not OSHA's confined spaces, and our research holds no figure for how often steamfitters work in permit-required spaces.
What it can do is name the employer duty the confined-space standard attaches to that work before anyone enters.
Safety training for steamfitters
For how the trade itself is learned, our guide to how to become a steamfitter walks the apprenticeship route step by step.
The safety-specific training option with a federal name is OSHA's Outreach Training Program.
Its 10- and 30-hour classes produce a course completion card, and OSHA states that none of the Outreach courses is considered a certification.
The 10-hour class is "intended to provide workers with awareness of common job-related safety and health hazards," while the 30-hour class is "more appropriate for supervisors or workers with some safety responsibility."
Two boundaries matter when you read an "OSHA card required" job ad.
First, the Outreach program is a "voluntary program" that "does not meet the training requirements for any OSHA standards" and is not an OSHA requirement — though "some states, municipalities or others may require outreach training as a condition of employment."
Second, the card proves a course was completed; it is not a certification of the worker.
Beyond Outreach classes, the two rules described earlier on this page sit on the employer's side where the standards say so: the confined-space standard makes the competent-person survey the employer's task before work begins, and the fall-protection standard requires the protection systems at six feet.
What a specific job requires you to complete before you start is a question for the employer hiring you and the jurisdiction you would work in.
This page is career information, not legal or safety advice. Injury figures are BLS statistics; the safety rules and training requirements that apply to a specific job come from your employer's safety program, OSHA, and your state or city — confirm them before you rely on them.
