TL;DR
An isopropyl alcohol (IPA) safety data sheet has 16 sections required by OSHA's Hazard Communication Standard (29 CFR 1910.1200). The main hazards: flammable liquid (flash point around 53°F/12°C), central nervous system depressant, eye and skin irritant. OSHA's permissible exposure limit is 400 ppm as an 8-hour TWA. Employers must keep the SDS accessible to workers during every shift.
What is an isopropyl alcohol safety data sheet and who has to have one?
A safety data sheet (SDS) is a standardized document that spells out a chemical's hazards, safe handling steps, physical properties, and emergency response information. For isopropyl alcohol (IPA, also called isopropanol or 2-propanol), that document is mandatory any time the chemical sits in a workplace covered by OSHA's Hazard Communication Standard at 29 CFR 1910.1200.[1]
The rule is simple. If IPA is in your facility and an employee could be exposed to it, you need the SDS on hand and accessible. That covers a nail salon using IPA as a sanitizer and a machine shop using it as a parts cleaner.
OSHA aligned its SDS format with the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS) in 2012, which is why you'll still hear the old term "material safety data sheet" (MSDS) used as if it means the same thing as SDS. The formats are different in ways that matter. An MSDS was unstructured and could have 7, 8, or 16 sections depending on the supplier. The current GHS-aligned SDS always has exactly 16 sections in a fixed order.[1] If you're working off an old MSDS for IPA, get the current SDS from your supplier.
Under 29 CFR 1910.1200(g), chemical manufacturers and importers must ship an SDS with every initial shipment of a hazardous chemical. Employers must keep those sheets accessible to employees during all work shifts.[1] "Accessible" means workers can get to them without asking a supervisor for permission, which rules out locked cabinets nobody can open after hours.
What are the 16 mandatory sections of an isopropyl alcohol SDS?
OSHA's HazCom standard defines what each of the 16 sections must contain. Here's what shows up in a typical IPA SDS, and what actually earns your attention in each one for day-to-day compliance.
Section 1: Identification. Product name, manufacturer contact, recommended uses, and emergency phone number. For IPA you'll see CAS number 67-63-0 listed here.
Section 2: Hazard Identification. GHS hazard classifications and the signal word ("Danger" for IPA). IPA is classified as Flammable Liquid Category 2 and an eye irritant. This is the section your workers glance at in an emergency.
Section 3: Composition/Information on Ingredients. For pure IPA, this is short. For blended products marketed as "isopropyl alcohol," watch for co-solvents or denaturants listed here that carry their own hazards.
Section 4: First-Aid Measures. Eyes: flush with water for 15 minutes. Skin: wash with soap and water. Ingestion: get immediate medical attention (IPA is toxic when swallowed). Inhalation: move to fresh air, seek medical care if symptoms persist.
Section 5: Fire-Fighting Measures. IPA burns easily. Flash point is around 53°F (12°C) for pure IPA, and 70% solutions run slightly higher.[2] Suitable extinguishing media: CO2, dry chemical, alcohol-resistant foam. Plain water won't control an IPA fire.
Section 6: Accidental Release Measures. Kill ignition sources first. Ventilate the area. Wear appropriate PPE. Absorb spills with inert material, not sawdust or other combustible absorbers. Dispose per local rules.
Section 7: Handling and Storage. Keep away from heat, sparks, and open flames. Store in a cool, well-ventilated area in tightly closed containers. Ground and bond containers when transferring to stop static discharge. This section often says to store IPA away from oxidizers.
Section 8: Exposure Controls/Personal Protection. This is where OSHA's exposure limits live. More on those in the next section.
Section 9: Physical and Chemical Properties. Clear, colorless liquid. Characteristic odor. Boiling point around 82°C (180°F). Vapor density greater than air, so the vapors sink and pool at floor level, which changes how you plan ventilation.
Section 10: Stability and Reactivity. IPA is stable under normal conditions. It reacts with strong oxidizers, strong acids, and strong bases. Decomposition products include carbon monoxide and carbon dioxide.
Section 11: Toxicological Information. Acute effects (high-concentration inhalation causes dizziness, headache, CNS depression). Chronic effects (limited data, with repeated heavy exposure linked to liver effects in animal studies). IARC has not classified IPA itself as a carcinogen.[3]
Section 12: Ecological Information. IPA is readily biodegradable and has low aquatic toxicity, though large spills can still strip oxygen from waterways.
Section 13: Disposal Considerations. IPA is usually a flammable waste and has to go out per federal, state, and local rules. Don't pour it down the drain in large quantities.
Section 14: Transport Information. DOT Hazard Class 3 (flammable liquid) above de minimis thresholds. UN number: UN1219.
Section 15: Regulatory Information. TSCA listing, CERCLA reportable quantity, state right-to-know laws, and other regulatory status.
Section 16: Other Information. Issue date and revision date. Check this every time to confirm your SDS is current.
What are the OSHA exposure limits for isopropyl alcohol?
OSHA's permissible exposure limit (PEL) for isopropyl alcohol is 400 ppm as an 8-hour time-weighted average (TWA), set under 29 CFR 1910.1000 Table Z-1.[4] That's the legal ceiling for general industry. Construction and maritime use the same value through their own cross-references.
NIOSH recommends 400 ppm TWA plus a 500 ppm short-term exposure limit (STEL) over 15 minutes.[5] The American Conference of Governmental Industrial Hygienists (ACGIH) goes lower, with a Threshold Limit Value (TLV) of 200 ppm TWA and 400 ppm STEL. Plenty of industrial hygienists aim for the ACGIH number in practice, because OSHA's PELs are mostly frozen where they landed in 1971 and don't always match current health science.
Here's the working takeaway. If your people use IPA in any real quantity in an enclosed space, measure the air when you have reason to think exposures could climb. The odor threshold for IPA sits around 22 ppm, so you'll smell it long before you hit 400 ppm. Smell is an early warning, not a monitor. If you can smell IPA all shift, you're likely running somewhere in the low hundreds of ppm, and it's time to check with a real instrument.
| Limit | Value | Authority | Legal Force |
|---|---|---|---|
| PEL (TWA) | 400 ppm | OSHA 29 CFR 1910.1000 | Legally enforceable |
| REL (TWA) | 400 ppm | NIOSH | Recommended only |
| REL (STEL) | 500 ppm | NIOSH | Recommended only |
| TLV (TWA) | 200 ppm | ACGIH | Recommended only |
| TLV (STEL) | 400 ppm | ACGIH | Recommended only |
What PPE does an isopropyl alcohol SDS typically require?
Section 8 of the IPA SDS covers exposure controls and personal protective equipment, and what it calls for depends on the task and the concentration. Here's the setup you'll see most often.
Eye and face protection: safety glasses with side shields for routine use. Chemical splash goggles if anything could splash, like pouring or mixing.
Skin protection: nitrile gloves are the standard pick for IPA. Natural rubber latex resists IPA poorly. Butyl rubber holds up better for extended contact. For heavy skin exposure, add a chemical-resistant apron.
Respiratory protection: for routine work with good ventilation and exposures below the PEL, no respirator is required. If ventilation is weak or concentrations are unknown, a half-face respirator with organic vapor cartridges fits the job. Any respirator use triggers OSHA's respiratory protection standard at 29 CFR 1910.134, which requires a written program, medical evaluation, and fit testing.[6]
For how PPE requirements slot into OSHA's hazard communication framework, see our guide on hazard communication.
Ventilation is usually the cheapest control that works. A well-designed local exhaust ventilation (LEV) system can hold air concentrations far below the PEL with no respirator at all. Use IPA in a small, sealed room with no exhaust, though, and a respirator stops being optional.
What are the fire and flammability hazards of isopropyl alcohol?
Flammability is the hazard that kills people with IPA. The liquid has a flash point around 53°F (12°C) for the pure substance and roughly 54 to 55°F (12 to 13°C) for 70% solutions, so it can ignite at room temperature.[2] That's not theory. It's a live risk in any facility that isn't at least somewhat climate-controlled.
The flammable range for IPA runs about 2% to 12.7% in air by volume. The lower explosive limit is 2%, which means it takes very little vapor in the air to set up an ignition risk.
Vapors are heavier than air, with a vapor density around 2.1 against air at 1.0. They sink and travel along floors toward drains, pits, or low spots where electrical equipment or pilot lights wait. That's why Section 7 of the SDS keeps hammering on grounding, bonding, and keeping IPA away from heat and ignition sources.
Static electricity ignites IPA. Pour it from one container to another and static builds. Bond both containers to each other and to ground before you transfer.
NFPA 30, the Flammable and Combustible Liquids Code, classifies IPA as a Class IB flammable liquid because its flash point is below 73°F and its boiling point is at or above 100°F.[7] That classification drives your storage: flammable storage cabinets, quantity limits, and ventilation for storage areas.
If you store real quantities, OSHA's standard at 29 CFR 1910.106 lays out the flammable liquid storage rules.
How does the isopropyl alcohol SDS compare to other common solvents like dichloromethane?
This question comes up because IPA and dichloromethane (DCM, also called methylene chloride) are both everyday industrial solvents, and their hazards point in opposite directions. IPA's danger is fire. DCM's danger is what it does to your body.
DCM doesn't burn the way IPA does. Its flash point sits around -9°C (15°F) by some test methods, but in ordinary air at ambient temperatures it's often treated as non-flammable, which makes people careless. The real DCM hazard is toxicity. OSHA wrote a standard just for it at 29 CFR 1910.1052 because DCM is a probable human carcinogen (IARC Group 2A) and your body converts it to carbon monoxide, which can cause fatal CO poisoning.[8] The OSHA PEL for DCM is 25 ppm TWA against 400 ppm for IPA. That's a 16-fold gap.
A dichloromethane safety data sheet looks structurally identical to an IPA SDS, same 16 GHS sections, but Sections 2, 8, and 11 read far more demanding. DCM pulls in medical surveillance, stricter respiratory protection, and regulated-area controls that IPA never triggers.
Swapping DCM for IPA in a process (which many shops did to cut carcinogen exposure) trades a serious carcinogen for a fire hazard. That's often a smart trade. It still means updating your SDS library, your written hazard communication program, and maybe your fire suppression and storage. You can't swap the chemical and assume the old controls hold.
Under the old MSDS system, the dichloromethane sheet often read better on toxicology than IPA's did, simply because DCM drew more regulatory heat. The current GHS SDS format puts both on the same 16-section skeleton.
| Property | Isopropyl Alcohol | Dichloromethane |
|---|---|---|
| CAS Number | 67-63-0 | 75-09-2 |
| Flash Point | ~53°F (12°C) | Non-flammable (practical) |
| OSHA PEL | 400 ppm TWA | 25 ppm TWA |
| OSHA-Specific Standard | No | Yes (29 CFR 1910.1052) |
| IARC Carcinogen Classification | Not classified | Group 2A (probable) |
| Key Hazard | Flammability | Carcinogenicity, CO poisoning |
| GHS Signal Word | Danger | Danger |
What does OSHA require you to do with an SDS once you have it?
Having the SDS is step one. OSHA's HazCom standard at 29 CFR 1910.1200(g)(8) requires employers to "maintain in the workplace copies of the required safety data sheets for each hazardous chemical in the workplace, ensure that they are readily accessible during each work shift to employees when they are in their work area(s)."[1]
Readily accessible is the phrase that gets tested. OSHA accepts electronic SDS systems (binders on a tablet, cloud systems reachable from a kiosk) as long as employees can pull a sheet fast, without barriers, and without asking a supervisor. If your system goes down, you need a backup. Paper binders as a fallback aren't old-fashioned. They're smart.
You also have to train workers to read and use the SDS. Under 29 CFR 1910.1200(h), employees get trained at initial assignment and whenever a new hazard shows up.[1] Training has to cover how to find the SDS, what each section means, and how to turn that information into protection for themselves.
For OSHA training purposes, HazCom is one of the standards inspectors cite most. Hazard communication was the second most cited OSHA standard in general industry in fiscal year 2023, with the standard drawing thousands of citations that year, and missing or outdated SDSs and training gaps among the usual specifics.[9]
If you're building or refreshing a written hazard communication program, SafetyFolio's safety program generator produces a compliant HazCom program in about 15 minutes, SDS management and training documentation included.
Here's the piece small employers miss most. You need a written hazard communication program that names your chemical inventory, describes how SDSs are kept and reached, and explains your labeling. The SDS is not the program. It's one part of it.
How do you read the exposure limits and health hazard sections of an IPA SDS accurately?
Section 8 (Exposure Controls) and Section 11 (Toxicological Information) are the two people botch most, either by reading them into a panic or skimming right past.
On Section 8: exposure limits track the jurisdiction of the SDS. A US IPA sheet lists OSHA's PEL, NIOSH's REL, and ACGIH's TLV. These are air concentrations, measured in parts per million (ppm) or milligrams per cubic meter (mg/m3). For IPA, 400 ppm works out to roughly 980 mg/m3 at standard temperature and pressure, which you might see printed next to the ppm value.
On Section 11: the toxicology usually comes from animal studies or occupational medicine case reports. For IPA, acute inhalation studies in animals show CNS depression at high concentrations. The LD50 (oral, rat) for IPA is around 5,045 mg/kg, which puts it in a fairly low acute oral toxicity band for an industrial solvent. That doesn't mean you can drink it. It means an accidental skin splash isn't the same risk as swallowing it on purpose.
Watch Section 11 for carcinogenicity notes from IARC, NTP, or OSHA. For pure IPA, IARC evaluated it and found "inadequate evidence" to classify it as a human carcinogen.[3] IARC also looked at isopropyl alcohol manufacture using the strong-acid process and found sufficient evidence for nasal sinus cancer in that specific occupational setting. The distinction is real. Using IPA as a solvent is nothing like working inside an IPA production plant.
If your SDS comes from a supplier who blends IPA with other solvents, read Section 3 before you take Section 11 at face value. The toxicology of the blend can differ from pure IPA.
What first aid and emergency procedures does the IPA SDS require you to have ready?
Section 4 of the IPA SDS covers first aid and Section 6 covers accidental release. Here's what your response has to look like when something goes wrong.
Eye contact: flush immediately with large amounts of water for at least 15 minutes. Remove contact lenses if they come out easily. Get medical attention if irritation sticks around. OSHA's 29 CFR 1910.151 requires suitable facilities for quick drenching or flushing of eyes and body where employees may be exposed to injurious materials. An eyewash station within 10 seconds of travel from the IPA use area is the standard reading.[10]
Skin contact: strip off contaminated clothing and wash with soap and water. IPA does absorb through skin, though not fast enough to cause systemic poisoning from brief contact. Repeated or prolonged contact defats the skin and causes dermatitis.
Inhalation: get the person to fresh air. If they're unconscious or not breathing, call 911 and start rescue breathing if you're trained. Don't hand out oxygen unless you're a trained medical professional with the gear to do it safely.
Ingestion: this is the bad one. IPA is toxic when swallowed. A potentially lethal dose in an adult is estimated around 250 mL (about 8 oz) of pure IPA, and much smaller amounts can cause serious harm. Call Poison Control right away (1-800-222-1222 in the US).[11] Do not induce vomiting.
Spill response: isolate the area, kill ignition sources (switch off nearby electrical equipment if you can do it safely), ventilate, and use an inert absorbent to contain it. Large spills may need evacuation and emergency services, depending on quantity. To put it in perspective, a 5-gallon spill of IPA in a poorly ventilated room can build both a serious fire hazard and heavy vapor exposure.
To document any injury or near-miss involving IPA, an incident report is where your OSHA recordkeeping starts.
How do you build a compliant SDS management system for a small business?
Small employers tend to treat SDS management as a filing problem. It's a communication problem. The whole point is getting hazard information to the worker who needs it, fast, when they need it. Build the system around that and compliance falls out the other end.
Step one: chemical inventory. List every chemical in your facility. Include the product name, the SDS revision date, and where the sheet lives. OSHA doesn't demand a specific format, but you have to prove you hold a current SDS for every hazardous chemical.
Step two: current SDSs. Check revision dates across the board. No OSHA rule says an SDS expires after X years, but if a sheet is more than 5 to 7 years old, ask your supplier for a fresh one. Manufacturers must revise the SDS within 3 months of learning significant new information about a chemical's hazards.[1]
Step three: access. Pick paper, electronic, or hybrid. For most small businesses, hybrid wins: a cloud system as primary (workers pull a sheet on a phone or tablet) with a paper binder as backup. Go fully electronic and you have to document the access method inside your written HazCom program.
Step four: train your people. New hires before they touch chemicals. Everyone again when you add new chemicals. Periodic refreshers are good practice even though OSHA only mandates initial and change-triggered training.
Step five: tie the SDS system to your labeling. Labels and SDSs work as a pair under HazCom. The pictograms and hazard statements on a container label come from the same GHS classification that structures the SDS. Workers should be able to connect what they read on the label to the full detail on the sheet.
For the written program that holds all of this together, our hazard communication guide walks the full requirements. SafetyFolio's safety program generator builds the written HazCom structure if you need something in place fast.
What are the most common OSHA citations related to isopropyl alcohol and SDS compliance?
OSHA doesn't publish citation data by individual chemical, but the violations that hit IPA-heavy workplaces (salons, medical facilities, labs, manufacturing, cleaning crews) cluster around the same few failures.
Missing or inaccessible SDSs top the list. Inspectors ask to see the SDS for chemicals on site. Can't produce it, or workers don't know where to find it, and that's a violation of 29 CFR 1910.1200(g).
Outdated SDSs in the old MSDS format still turn up, mostly in places that have run for years without touching their chemical management. OSHA once accepted old MSDS documents during the transition, but if you're still on pre-2012 MSDSs, you're years overdue.
Missing or non-compliant container labels are the second big category. Decant IPA into an unlabeled spray bottle and that's a citation under 29 CFR 1910.1200(f). Portable container labeling is a bit looser (you don't need a full GHS label on a spray bottle one worker fills and empties in a single shift), but the requirements are still real and specific.
No written HazCom program is cited right alongside SDS gaps. These come as a package deal. As of 2024, a serious violation runs up to $16,131, with repeat or willful violations up to $161,323.[9]
Flammable liquid storage violations, cited under 29 CFR 1910.106, also surface in IPA inspections. Storing large amounts of IPA in unapproved containers or without a proper flammable storage cabinet is a common finding in salon and lab visits.
Where can you get a current isopropyl alcohol SDS, and how do you verify it's GHS-compliant?
Your chemical supplier is the best source for a current IPA SDS. Ask for it directly or download it from the product page. Major suppliers like Sigma-Aldrich (MilliporeSigma), VWR, and Fisher Scientific keep current GHS-format SDSs for IPA and update them when the science or regulation changes.
To confirm a sheet is GHS-compliant, run through a few quick checks.
Does it have exactly 16 sections numbered in sequence? If yes, it's GHS-structured. Fewer sections or a different order means you're holding an old MSDS.
Does Section 2 carry GHS hazard statements and pictograms? For IPA, expect the flame pictogram (flammable liquid) and the exclamation mark pictogram (eye irritant, CNS effects) at minimum. Those are the H-statements GHS requires.
Does Section 1 name a supplier and an emergency contact? Required.
Does Section 16 carry an issue date and a revision date? Required. If the revision date is missing, treat the sheet as suspect.
For pure IPA (CAS 67-63-0), cross-check against the NIOSH Pocket Guide to Chemical Hazards, which lists the exposure limits you should see reflected in Section 8.[5] If the numbers in your SDS don't match what OSHA and NIOSH publish for IPA, the sheet is probably wrong or out of date.
Don't grab an SDS off a random search result without checking the source. Aggregator sites host outdated and flat-out inaccurate sheets. Go to the manufacturer.
Frequently asked questions
Is isopropyl alcohol considered a hazardous chemical under OSHA?
Yes. IPA is a hazardous chemical under OSHA's Hazard Communication Standard at 29 CFR 1910.1200 because it carries physical hazards (flammable liquid) and health hazards (eye irritant, CNS depressant at high concentrations). Any employer with IPA in the workplace needs a current SDS, proper container labels, and a written HazCom program with employee training.
Can I use a material safety data sheet (MSDS) instead of an SDS?
No, not for current compliance. OSHA moved from MSDS to the GHS-aligned 16-section SDS format in 2012, with full compliance required by June 1, 2016. An old MSDS for IPA may still hold useful information, but it doesn't meet current HazCom requirements. Contact your supplier for the current GHS-format SDS.
What is the OSHA permissible exposure limit for isopropyl alcohol?
OSHA's PEL for isopropyl alcohol is 400 ppm as an 8-hour time-weighted average (TWA), set under 29 CFR 1910.1000 Table Z-1. NIOSH recommends the same 400 ppm TWA plus a 500 ppm STEL. ACGIH recommends a stricter 200 ppm TWA. Only the OSHA PEL is legally enforceable; the NIOSH and ACGIH values are guidance.
Does 70% isopropyl alcohol have a different SDS than 99% isopropyl alcohol?
Yes, some physical properties differ, mainly flash point (70% IPA has a slightly higher flash point than 99%) and vapor pressure. Both are flammable liquids. The GHS hazard classifications are similar, but the specific values in Sections 8 and 9 can differ. Always use the SDS that matches the exact concentration of IPA you're using.
How often do I need to update my isopropyl alcohol SDS?
OSHA sets no fixed expiration date for SDSs. Manufacturers must revise an SDS within 3 months of learning significant new hazard information under 29 CFR 1910.1200(g)(5). In practice, check your revision dates every 3 to 5 years and request updated versions from your supplier. For a stable, well-studied chemical like IPA, major revisions are rare.
What are the flammable storage requirements for isopropyl alcohol?
IPA is a Class IB flammable liquid under NFPA 30. OSHA's 29 CFR 1910.106 governs flammable liquid storage in general industry. Requirements include approved containers (safety cans for quantities over 1 gallon outside original containers), flammable storage cabinets for inside storage, quantity limits per area, and adequate ventilation. Exact limits depend on your building type, sprinkler status, and storage area.
Do nail salons and hair salons need an SDS for isopropyl alcohol?
Yes. Salons with employees are covered by OSHA's HazCom standard. IPA gets heavy use in salons for sanitizing and nail prep. Inspectors do cite salons for HazCom violations, including missing SDSs and thin training. Salon workers also face real inhalation exposures in poorly ventilated spaces, which makes the exposure limit and ventilation sections of the IPA SDS worth a close read.
How is the isopropyl alcohol SDS different from the dichloromethane SDS?
Both use the same 16-section GHS format, but the hazards diverge hard. IPA's main hazard is flammability; DCM's are carcinogenicity (IARC Group 2A) and CO poisoning from how the body metabolizes it. OSHA's PEL for DCM is 25 ppm against 400 ppm for IPA. DCM also has a specific OSHA standard (29 CFR 1910.1052) with medical surveillance requirements that IPA never triggers.
What PPE is required when working with isopropyl alcohol?
For routine use with good ventilation: safety glasses and nitrile gloves at minimum. For splash risk: chemical goggles and a chemical-resistant apron. For high-concentration or confined-space work with weak ventilation: add an organic vapor respirator. Respirator use triggers the full requirements of 29 CFR 1910.134, including a written program, medical evaluation, and fit testing. Ventilation controls beat respirators when feasible.
Does electronic storage of SDSs satisfy OSHA's accessibility requirement?
Yes. OSHA has stated that electronic SDS systems are acceptable as long as employees can reach the information immediately, without barriers, during their shift, and OSHA has issued letters of interpretation confirming this. You need a backup method (paper binders are common) for outages, and workers must be trained on how to use the electronic system.
What first aid steps should I take if someone inhales too much isopropyl alcohol vapor?
Move the person to fresh air right away. If they're conscious and breathing, have them rest and watch for dizziness, headache, and nausea. If unconscious or not breathing, call 911. If symptoms are significant, get medical attention even if the person perks up fast, because CNS effects from high IPA exposure can recur. Contact Poison Control (1-800-222-1222) for guidance.
What OSHA violations can I get cited for related to isopropyl alcohol?
Common citations: no SDS or inaccessible SDS (29 CFR 1910.1200(g)), unlabeled containers (29 CFR 1910.1200(f)), no written HazCom program (29 CFR 1910.1200(e)), thin employee training (29 CFR 1910.1200(h)), and improper flammable liquid storage (29 CFR 1910.106). Serious violation penalties can reach $16,131 per violation as of 2024. HazCom stays among OSHA's top 10 most cited standards year after year.
Where can I find a free isopropyl alcohol SDS?
Your IPA supplier is the best source. Major chemical suppliers (MilliporeSigma, Fisher Scientific, VWR) post current GHS SDSs free on their product pages. NIOSH's International Chemical Safety Cards give a summary of hazards. Skip aggregator sites that may host outdated versions. The NIOSH Pocket Guide to Chemical Hazards is a reliable reference for exposure limits and basic hazard data.
Is isopropyl alcohol a carcinogen?
For occupational use as a solvent, IPA is not classified as a human carcinogen by IARC, NTP, or OSHA. IARC evaluated isopropyl alcohol itself and found inadequate evidence for carcinogenicity. IARC did classify the manufacture of isopropyl alcohol using the strong-acid process as a Group 1 carcinogen, an exposure context specific to that production process, which is a different situation from using IPA as a cleaning solvent.
