Wash your hands and face before you eat, drink or smoke, and again at the end of the shift. That is the rule OSHA writes into its chromium (VI) standard for workers whose skin contacts Cr(VI), typical of stainless welding; its lead standard carries a near-identical rule where airborne lead exceeds the permissible exposure limit. Neither names a soap. For what welding leaves on hands — grinding dust, shop grease, black bench residue — a scrubber soap does the work. For the fume you breathe, soap does nothing.
The short version
The reader here is a welder, a fabrication-shop owner or the safety lead deciding what goes at the shop’s wash sink, usually after somebody asks what has to come off before lunch. Everything below comes from two OSHA standards, an OSHA fact sheet and a NIOSH page, linked where used. Five facts carry the decision:
- Welding fume carries metals. OSHA’s welding fact sheet lists eighteen, from aluminum to zinc, and says the chromium in stainless steel is converted to hexavalent chromium, Cr(VI), during welding.
- The Cr(VI) standard sets the wash schedule. Where skin contact with chromium (VI) occurs, 29 CFR 1910.1026 requires hands and faces washed at the end of the shift and before eating, drinking, smoking, chewing tobacco or gum, applying cosmetics or using the toilet.
- The lead standard has a matching rule, but only where airborne lead is above the permissible exposure limit, the PEL.
- Neither standard names a soap. The Cr(VI) text asks for washing facilities “capable of removing chromium (VI) from the skin” and stops there. OSHA certifies no product, ours included.
- Soap is for the residue, not the fume. A scrubber soap handles grinding dust, shop grease and anti-spatter film. It does nothing for what you inhale, and nothing for arc or spatter burns.
Neither standard applies to every welding shop; whether one reaches yours depends on what you weld and what your exposure monitoring shows. This post is general information, not legal or medical advice.
What welding and fabrication leave on your skin
Welding fume is the hazard OSHA’s documents dwell on, and its contents are why the wash rule exists. OSHA’s fact sheet Controlling Hazardous Fume and Gases during Welding (FS-3647, archived copy) answers “What is in welding fume?” with a list of metals: “Aluminum, Antimony, Arsenic, Beryllium, Cadmium, Chromium, Cobalt, Copper, Iron, Lead, Manganese, Molybdenum, Nickel, Silver, Tin, Titanium, Vanadium, Zinc.” Which of those are in your fume depends on base metal, coating and consumable; the sheet does not map them one to one, and neither does this post.
Chromium gets the sheet’s specific attention. “Chromium is a component in stainless steel, nonferrous alloys, chromate coatings and some welding consumables.” “Chromium is converted to its hexavalent state, Cr(VI), during the welding process.” Its warning is blunt: “Cr(VI) fume is highly toxic and can damage the eyes, skin, nose, throat, and lungs and cause cancer.” That is a statement about fume, which is breathed; skin comes into it because particulate from fume and grinding settles on hands, wrists and face. The chromium (VI) standard opens its hygiene section with the words “Where skin contact with chromium (VI) occurs”, which is OSHA’s acknowledgement that it does.
Fume is not the only thing on a fabricator’s hands, or the most visible. Grinding and cutting throw metal dust that works into skin creases and under nails. Anti-spatter spray leaves a film. Fixtures, clamps and machines carry ordinary grease, and grease binds the dust into the black layer you see at the sink. Those soils are what a hand cleaner is for, and what this post means by soap.
Wash before eating and at the end of the shift: the chromium (VI) rule
The chromium (VI) standard for general industry, 29 CFR 1910.1026, contains the most specific hand-washing schedule a welder is likely to fall under. The fact sheet points to it: “OSHA regulates worker exposure to Cr(VI) under its Chromium (VI) standard, 29 CFR 1910.1026 and 1926.1126.” The second sits in Part 1926, the construction standards; this post follows the general-industry text.
Paragraph (i)(1) sets the trigger: “Where skin contact with chromium (VI) occurs, the employer shall provide washing facilities in conformance with 29 CFR 1910.141.” Paragraph (i)(3)(i) says what those facilities must be: “The employer shall provide readily accessible washing facilities capable of removing chromium (VI) from the skin, and shall ensure that affected employees use these facilities when necessary.” Paragraph (i)(3)(ii) sets the schedule: “The employer shall ensure that employees who have skin contact with chromium (VI) wash their hands and faces at the end of the work shift and prior to eating, drinking, smoking, chewing tobacco or gum, applying cosmetics, or using the toilet.”
Three things in that text matter at the sink. The rule covers the face, not just the hands. The trigger is skin contact, not welding as such: a stainless shop is the typical case, since the fact sheet puts chromium in stainless steel and Cr(VI) in the fume, but a shop whose base metals, coatings and consumables contain no chromium may fall outside it, and that call belongs to whoever runs your exposure assessment, not to a soap company. And the standard names no product: “capable of removing chromium (VI) from the skin” is the whole specification. The sink itself must also meet the general sanitation standard, 29 CFR 1910.141(d), which requires soap or a similar cleansing agent, running water and a way to dry hands at every lavatory; the OSHA hand-soap post covers it and this one does not.
Does the lead standard apply to a welding shop?
The lead standard applies to a welding shop only where airborne lead is above OSHA’s permissible exposure limit; its hygiene rule is keyed to that measurement, not to any base metal or process. Lead is on the fact sheet’s list of fume metals, which is why the question comes up. The general-industry lead standard, 29 CFR 1910.1025, says at paragraph (i)(4)(iii): “The employer shall assure that employees who work in areas where their airborne exposure to lead is above the PEL without regard to the use of a respirator wash their hands and face prior to eating, drinking, smoking or applying cosmetics.”
Two details deserve a second read. The rule counts the air concentration “without regard to the use of a respirator”, so on a plain reading a respirator does not lift the washing duty. And the schedule is the same shape as the chromium rule: hands and face, before eating, drinking, smoking or applying cosmetics. A shop that has never measured its lead exposure does not know which side of the PEL it is on; whether or not the rule applies, the habit it describes costs nothing.
Wash before you leave, or the residue goes home
Take-home exposure is the reason the end-of-shift wash matters even when nobody is about to eat. NIOSH’s page on take-home exposures puts it in one sentence: “Chemicals from your work can come home on your skin, hair, clothes and shoes.” Its examples overlap with the welding fume list: “Examples of take-home exposures include lead, pesticides, beryllium, and asbestos.” Lead and beryllium are both on OSHA’s list of fume metals. NIOSH’s instruction is plain: “Wash your hands before leaving work.”
For a welder the practical version is the one the Cr(VI) standard spells out: hands and face at the end of the shift, before the truck, before the kids. The diagram above has the three moments: before food, drink or a smoke; hands and face at the end of the shift; and before you leave, so what is on your skin stays at the shop.
Four shop situations, what ends up on skin, and when to wash
The table below maps four common weld and fab situations to what they leave on skin and when to wash. The metal names come only from OSHA’s fact sheet, which ties only one metal to one material, chromium to stainless steel, so the other rows stay generic on purpose. Which standard, if any, reaches your shop depends on your own exposure assessment.
| Situation | What ends up on skin | When to wash | Rule that speaks to it |
|---|---|---|---|
| Stainless welding | Fume particulate. Chromium is a component of stainless steel and is converted to Cr(VI) during welding, per OSHA’s fact sheet. | Hands and face at the end of the shift and before eating, drinking, smoking, chewing tobacco or gum, applying cosmetics or using the toilet | 29 CFR 1910.1026(i)(3)(ii), where skin contact with chromium (VI) occurs |
| Galvanized or otherwise coated steel | Fume and dust from the coating and the base metal; which metals depends on the coating, and we name none here. | Same schedule as a matter of practice: before eating, drinking or smoking, and at the end of the shift | Depends on what the coating contains and what your monitoring shows; 29 CFR 1910.141(d) governs the sink regardless |
| Mild-steel grinding, cutting and fit-up | Metal dust from grinding, and the black residue it leaves in skin creases and under nails | Before eating, at the end of the shift, and whenever hands are visibly loaded | 29 CFR 1910.141(d): soap or a similar cleansing agent, running water and drying at every lavatory |
| Shop grease, anti-spatter and machine oil | Oily film that binds dust to skin; the soil a hand cleaner is designed for | Whenever it is on your hands, and always before eating | 29 CFR 1910.141(d) |
Lead is deliberately missing from the rows: its rule at 1910.1025(i)(4)(iii) is triggered by an air measurement above the PEL, not by a base metal or process, so it cannot be pinned to one row. Where it applies, its schedule matches the stainless row.
Which soap belongs at a weld-shop sink?
No soap is required, approved or certified by either standard, so the choice is yours, and it should rest on the soils in the table, not on a compliance claim. The Cr(VI) standard asks for washing facilities “capable of removing chromium (VI) from the skin”, names no product type, and OSHA certifies no product. We, StretchRite LLC, sell Power One Soap, and we make no claim that it removes chromium (VI) or any other metal from skin: no test we can cite says so, and a soap sold as OSHA-approved is claiming an approval that does not exist.
What Power One is built for is the residue: grinding dust, shop grease, anti-spatter film and the black layer that a day at the bench leaves in skin creases. The formula is only about 20 percent water, its scrubber is nearly 20 percent cosmetic-grade walnut shell, it has no petroleum solvents and six skin emollients, and it is made in the USA. The 3.55 L bottle is $35.40 and gives 710 washes at a 5.0 mL metered dose, $0.0499 a wash. It loads upside-down into a wall dispenser that is guaranteed for life, $18.95 on its own or $53.50 with the first bottle. A shop running several sinks buys the case of four at $140.50, and case and bulk quotes go through our contact page.
Two sibling posts finish the job. Where the station goes, how fast warm water has to arrive and why drying is where most shop stations fail is the business of the hand-wash station post. And if the nearest thing for anti-spatter or grease is a solvent can, the brake-cleaner-and-gasoline post explains why that is a bad trade: a solvent strong enough to clean the part strips the skin, at a weld bench as much as in a service bay.
Where soap is the wrong tool
Soap solves the smaller part of a welder’s exposure. Naming the rest plainly matters more than anything above about our product.
- Fume you breathe. Nothing at the sink changes what reached your lungs during the shift. Ventilation and respiratory protection are a separate discipline with their own rules; this post has no source on them and says nothing more.
- Arc burns. Ultraviolet and infrared from the arc burn exposed skin and eyes. Soap has no part in that.
- Spatter and hot-metal burns. A contact burn from spatter or a hot part is an injury, not a soil. Soap does nothing for it.
- Cracked, split or burned hands. Do not scrub them. An abrasive soap, walnut shell included, is the wrong tool on broken skin, and hands that stay cracked or bleed are a reason to see a clinician. The occupational-dermatitis post explains why exposure and washing habits outrank soap choice; the conclusion holds here.
- Fresh, heavy petroleum soil. For fresh transmission fluid, catalysed paint and two-pack epoxy, our mechanics’ buying guide concludes that pumice cuts faster than walnut shell. A fab shop that also runs a vehicle bay should read that before choosing one soap for both sinks.
The rule this post is built on costs nothing and needs no purchase: hands and face before you eat, drink or smoke, and again before you leave. Which soap sits at the sink is the second decision, made on what your hands look like at the end of the day, not on a certification nobody can give.
Frequently asked questions
How should welders clean their hands after welding?
With soap and running water, hands and face, before eating, drinking or smoking and at the end of the shift. That is the schedule OSHA's chromium (VI) standard, 29 CFR 1910.1026, sets where skin contact with Cr(VI) occurs, which is typical of stainless welding, and the lead standard mirrors it where airborne lead is above the PEL. A scrubber soap handles the grinding dust, shop grease and anti-spatter film that welding actually leaves on skin. Do not use brake cleaner, thinner or any other solvent as a hand cleaner, and no wash does anything about fume already inhaled.
Does OSHA require a specific hand soap for welders?
No. The chromium (VI) standard requires washing facilities “capable of removing chromium (VI) from the skin” and names no product type; the general sanitation standard, 29 CFR 1910.141(d), requires soap or a similar cleansing agent, running water and a way to dry hands at every lavatory. OSHA certifies no product, so no hand soap is OSHA-approved, ours included. This is general information about the standards, not legal advice.
Do welders have to wash their faces too, or just their hands?
Both, under both standards. Where skin contact with chromium (VI) occurs, 29 CFR 1910.1026(i)(3)(ii) requires that employees “wash their hands and faces at the end of the work shift and prior to eating, drinking, smoking, chewing tobacco or gum, applying cosmetics, or using the toilet”. Where airborne lead is above the PEL, 29 CFR 1910.1025(i)(4)(iii) requires that employees “wash their hands and face prior to eating, drinking, smoking or applying cosmetics”. The face is the part of the rule that is easiest to forget.
Does Power One Soap remove hexavalent chromium from skin?
We make no such claim. No test we can cite shows that Power One Soap, or any hand soap, removes chromium (VI) or other metals from skin, and whether a shop's washing facilities satisfy 1910.1026 is a determination for the shop's safety lead, not for a soap vendor. What Power One is built for is the ordinary weld-shop residue: grinding dust, shop grease, anti-spatter film and the black layer that a day at the bench leaves in skin creases. It is only about 20 percent water, uses nearly 20 percent cosmetic-grade walnut shell as its scrubber, contains no petroleum solvents, and carries six skin emollients.
Should I scrub burned or cracked hands after a shift?
No. An abrasive soap, walnut shell included, is the wrong tool on broken skin; a spatter burn or arc burn is an injury, not a soil, and soap does nothing for it. Hands that stay cracked or bleed are a reason to see a clinician. This is general information, not medical advice.
