Ask a small business owner where to find out what gloves their employees should wear for a given chemical, and most will guess. They'll reach for whatever box of gloves is on the shelf, or repeat whatever the last person used, or assume that "wear gloves" is specific enough. It isn't. The answer to "what protective equipment does this chemical require" is already written down, for every hazardous chemical in your building, in the same place every time: Section 8 of the Safety Data Sheet.
Section 8 is titled "Exposure Controls / Personal Protection," and it's the part of the SDS that translates a chemical's hazards into specific instructions — what exposure limits apply, what ventilation or other engineering controls are appropriate, and exactly what personal protective equipment (PPE) a worker needs. It's the closest thing to a PPE shopping list that exists for your workplace. And it's almost universally ignored, because it sits in the middle of a 16-page document that most people close after glancing at the first page.
This post is about reading Section 8 the way it's meant to be read and turning it into the PPE decisions OSHA actually requires — while avoiding the specific mistakes that put workers at risk even when everyone thought they were protected.
What Section 8 Is Required to Contain
The format of an SDS isn't a suggestion. OSHA's Hazard Communication Standard (29 CFR 1910.1200) specifies the content of all 16 sections in a mandatory appendix — Appendix D — and Section 8 has three required pieces of information. We covered the full 16-section structure in our plain-English guide to reading an SDS; here's what Appendix D requires specifically for Section 8:
Exposure limits. The OSHA permissible exposure limit (PEL), the ACGIH Threshold Limit Value (TLV), and any other exposure limit the manufacturer uses or recommends, where one is available. These are the airborne concentration thresholds — how much of the chemical can be in the air a worker breathes before it's considered hazardous over a given period.
Appropriate engineering controls. This is the manufacturer telling you what should be controlling exposure before PPE enters the picture — typically ventilation. Engineering controls (like local exhaust ventilation that captures vapor at the source) sit above PPE in the hierarchy of controls because they protect everyone in the area without depending on a worker correctly wearing equipment.
Individual protection measures, such as personal protective equipment. The PPE itself: gloves, eye and face protection, respiratory protection, protective clothing. This is where "wear gloves" should become "wear gloves of this material," and where the SDS tells you whether the chemical demands eye protection, a respirator, or both. Note the order: Section 8 lists engineering controls before PPE on purpose, because controlling a hazard with ventilation beats depending on a worker to wear equipment correctly.
Section 8 lists exposure limits, but those limits aren't the whole story. A chemical can be below its airborne exposure limit and still harm a worker through skin contact. That's why Section 8 also specifies gloves and protective clothing — and why "the air monitoring was fine" isn't the same as "the worker was protected." More on the skin-absorption trap below.
From Section 8 to the Law: The Hazard Assessment You Have to Certify
Reading Section 8 isn't just good practice — it feeds a legal obligation most small business owners don't know they have. OSHA's general PPE standard, 29 CFR 1910.132(d), requires every employer to assess the workplace to determine whether hazards are present that require PPE, and then to select PPE based on that assessment.
Here's the part that surprises people: the assessment has to be certified in writing. Under 1910.132(d)(2), the employer must verify that the hazard assessment was performed through a written certification that identifies four things — the workplace evaluated, the person certifying that the evaluation was done, the date or dates of the assessment, and a statement identifying the document as a certification of hazard assessment.
That's a standalone, citable requirement. It's not enough to hand out gloves and goggles; you have to be able to show an inspector a document proving you assessed which hazards exist and chose PPE accordingly. Section 8 of your SDSs is the raw material for that document — it's where the chemical-specific PPE needs come from. The hazard assessment is where you write them down and certify that you did the thinking.
Two related PPE standards work the same way, drawing their specifics from Section 8:
Hand protection (1910.138). Employers must select and require appropriate hand protection when employees' hands are exposed to hazards including skin absorption of harmful substances, chemical burns, and thermal burns. Critically, the standard says glove selection must be based on an evaluation of the glove's performance characteristics relative to the task, the conditions, the duration of use, and the hazards involved — not just "gloves," but the right gloves for this chemical and this job.
Eye and face protection (1910.133). Employers must ensure affected employees use appropriate eye or face protection when exposed to hazards from liquid chemicals, acids or caustic liquids, chemical gases or vapors, and flying particles, among others. The standard requires protectors to meet the ANSI/ISEA Z87.1 consensus standard.
One scope note worth knowing: the written-certification requirement in 1910.132(d) doesn't extend to respiratory protection, which has its own separate program standard (1910.134) with its own assessment rules. We'll get to respirators below — they're a category where the requirements are easy to trip over.
Gloves: Why the Wrong Material Is Worse Than None
Of all the PPE decisions, glove selection is the one where guessing does the most damage — because the wrong glove doesn't just offer less protection, it can offer negative protection. A glove that the chemical passes through traps that chemical against the skin and gives the worker a false sense of safety while the exposure continues.
Three things determine whether a glove actually protects against a specific chemical, and Section 8 (plus the glove manufacturer's own chemical-resistance chart) is where you find them:
Breakthrough time. How long it takes the chemical to work its way through the glove material from the outside to the inside. This is the number that matters most for a task with a known duration. A breakthrough time over eight hours (480 minutes) is rated excellent; a breakthrough time of fifteen minutes against a chemical you'll handle for an hour means the glove fails partway through the job.
Permeation rate. Once the chemical breaks through, how fast it moves through the material. Breakthrough and permeation together tell you how a glove behaves over time — not just whether it holds, but how quickly it stops holding.
Degradation. The physical breakdown of the glove on contact with the chemical — swelling, cracking, softening, or shrinking. A glove that degrades is failing visibly, but degradation and breakthrough aren't the same thing: a glove can let a chemical permeate through long before it shows any visible damage.
Material is the whole ballgame here, and the differences are dramatic. Peer-reviewed glove-permeation research has documented acetone permeating neoprene, and formaldehyde from a 37% formalin solution permeating natural-rubber latex gloves with breakthrough times of just 17 to 67 minutes — fast enough that a worker doing a sustained task is exposed well before the shift is over. The same body of research found that simulated hand movement shortened breakthrough times compared to the static laboratory test — for one solvent, by roughly 23% for latex and 31% for nitrile. The breakthrough numbers on a manufacturer's chart are best-case, measured on a flat, motionless sample; a real hand flexing and gripping breaks through faster.
A few practical anchors:
- Latex offers minimal protection against most organic solvents and carries a latex-allergy risk — it's a barrier against biological material, not a chemical-resistant glove.
- Nitrile is the workhorse disposable, but manufacturer charts generally rate it poorly against ketones such as acetone — always check the specific glove maker's chart, because formulations vary.
- Specialized materials — butyl, Viton, PVA, neoprene — exist because no single material resists everything. For fuels, for example, Viton has been among the most protective materials in published testing.
The lesson isn't to memorize a chemical-glove compatibility table. It's to stop treating gloves as interchangeable, read what Section 8 recommends for the specific chemical, cross-check it against the glove manufacturer's chemical-resistance chart, and match the glove's breakthrough time to how long the task actually takes.
"We've always used these gloves" is not a defense, and neither is "they're chemical gloves." If an employee handles acetone with a glove material acetone passes through in minutes, the glove is failing silently — the worker feels protected while the chemical soaks in. During an inspection, glove selection that doesn't match the SDS and the manufacturer's chemical-resistance data is a finding. More importantly, it's a real exposure happening every day until someone catches it.
Eyes and Face: Glasses, Goggles, or a Shield
Section 8 will tell you when a chemical demands eye protection, but it's worth understanding the distinctions, because "safety glasses" and "eye protection" are not synonyms when liquids are involved.
Safety glasses with side shields protect against flying particles — grinding, chipping, debris. They do very little against a chemical splash, because liquid can come in from above, below, or the sides. For a chemical that can splash, the right protection is chemical splash goggles that seal against the face. For severe splash hazards — pouring corrosives, pressurized spraying, handling large volumes — a face shield worn over goggles adds protection for the rest of the face, but a face shield alone is never sufficient eye protection because it doesn't seal.
The eye and face protection standard (1910.133) requires that whatever you choose meets ANSI Z87.1, which is the marking you'll find stamped on compliant protectors. If a chemical in your workplace carries the corrosion hazard, eye protection isn't the only requirement it triggers — corrosives also obligate you to provide emergency eyewash within reach, a subject with its own surprising depth that we covered in our guide to emergency eyewash station requirements. The pattern is the same one that runs through this entire post: the chemical's hazards, documented in its SDS, drive a cascade of specific obligations.
Eye and face protection is consistently among OSHA's most-cited standards — it appears on the annual Top 10 most-cited list year after year — and the citations usually come down to employees doing splash- or particle-hazard work in the wrong protection, or none at all.
Respirators: The N95 That Triggers a Program
Respiratory protection is the PPE category where small businesses most often stumble into an obligation they didn't know they'd created — because the line between "we handed out some dust masks" and "we now owe a written respiratory protection program" is closer than it looks.
Start with the principle: respirators sit at the bottom of the hierarchy of controls for a reason. If a chemical's airborne hazard can be handled with ventilation, that's the answer Section 8 wants you to reach for first. Respirators come into play when engineering controls aren't feasible or aren't enough — and the moment they do, OSHA's respiratory protection standard (1910.134) attaches.
Here's how the obligations break down:
Required use — meaning the employer requires a respirator, or exposures exceed an OSHA limit and a respirator is necessary to stay under it — triggers the full program: a written, worksite-specific respiratory protection program, a medical evaluation to confirm each worker can safely wear a respirator, fit testing, and training. None of it is optional once respirator use is required.
Voluntary use is where the surprises live. If you permit employees to use respirators that aren't strictly required — someone wants a dust mask for comfort while doing a dusty task — you must at minimum provide them the information in Appendix D of the respirator standard, a short document explaining the basics of safe voluntary respirator use. There's one carve-out: if the only voluntary use is filtering facepieces (the N95-style disposable dust masks), you don't have to build a full written program for that alone — just provide the Appendix D information.
The trap is what happens when voluntary use moves past filtering facepieces. OSHA has been explicit in interpretation that if employees voluntarily use elastomeric respirators — the reusable rubber half-masks with replaceable cartridges — the employer must implement the program elements needed to ensure those workers are medically fit to wear them and that the respirators are properly cleaned, stored, and maintained. The reusable half-mask that feels like a small upgrade from a dust mask quietly pulls you into program territory.
Respirators are also rated by an Assigned Protection Factor — a value in the respirator standard expressing how much a properly selected and fitted respirator is expected to reduce a worker's exposure. The takeaway for a non-specialist: the respirator has to be matched to the actual exposure, and one that isn't fit-tested can't be assumed to deliver its rated protection at all. This is why respiratory protection is one of the most-cited standards on OSHA's Top 10 list — businesses provide respirators without the program that makes them work.
Two Traps Hiding in the Exposure Limits
Section 8 lists exposure limits, and two things about those limits trip up even careful employers.
The PELs are old — often dangerously old. OSHA itself says so, in writing. On its Permissible Exposure Limits page, the agency states that it "recognizes that many of its permissible exposure limits (PELs) are outdated and inadequate for ensuring protection of worker health," noting that most PELs were issued shortly after the agency was created in 1970 and haven't been updated since. OSHA goes further and recommends that employers consider using more protective alternative exposure limits, because exposures that comply with an outdated PEL may still be hazardous.
This is why a good Section 8 lists more than the OSHA PEL — it includes the ACGIH TLV and often other limits, which frequently set a lower (more protective) ceiling than the federal PEL. OSHA publishes "Annotated PEL" tables that line up the OSHA PEL against the Cal/OSHA PEL, the NIOSH REL, and the ACGIH TLV side by side, precisely so employers can see where the federal limit lags. If the alternative limits in Section 8 are stricter than the PEL, treating the PEL as "good enough" may leave your workers under-protected. (One precise note: those annotated tables compare airborne limits and don't carry the skin-absorption notations — for those you have to look at the underlying OSHA Z-tables or the SDS itself.)
The "skin" notation means gloves aren't optional. Some chemicals carry a "skin" designation in the OSHA, NIOSH, or ACGIH tables. That notation means the chemical can be absorbed through intact skin and add to the dose a worker receives — which means meeting the airborne exposure limit does not, by itself, protect the worker. A chemical can be well under its PEL in the air and still be poisoning someone through their hands.
A concrete example sits in a product category we've written about before: 2-butoxyethanol, common in glass cleaners and degreasers, carries a skin notation. We flagged it in our guide to HazCom for janitorial and commercial cleaning companies — it's absorbed through the skin, which is exactly why gloves aren't a nicety for the cleaning crew using it all shift, they're load-bearing protection. When you see a skin notation in Section 8, read it as the SDS telling you that skin protection isn't a backup to ventilation — it's a primary control.
What This Looks Like When It Goes Wrong
The reason any of this matters isn't abstract. In April 2020, OSHA cited a Georgia bathtub-resurfacing contractor, Creative Multicare, after a worker died in October 2019 from inhaling lacquer/paint thinner on a job site. OSHA's news release on the case confirmed the agency found toluene exposure several times above permissible exposure limits, and cited the company for hazards including improperly labeled chemical mixtures, failure to provide emergency eye and body flushing, and flash-fire hazards.
Press reporting on the case put the penalty at $183,127, classified the violations as willful, and quoted the citation as finding that the company's hazard assessment was deficient because it didn't evaluate the need for chemical goggles or a face shield for employees using hazardous liquid chemicals. That's the through-line of this entire post in a single sentence: the hazard assessment failed because nobody connected the chemicals to the protection they demanded — and a worker died.
The financial stakes are real even when no one is hurt. A serious OSHA violation carries a penalty of $16,550, and a willful or repeat violation $165,514. (Those are 2025 figures, carried into 2026 unchanged because the annual inflation adjustment couldn't be calculated this year.) Each missing piece of PPE protection, and each missing certification, can be cited separately. But the penalty was never the point — the PPE in Section 8 is there to keep the worst day at your business from happening at all.
How Section 8 Becomes a System
Here's the gap between knowing all this and actually doing it. Section 8 has the answers, but they're scattered across one section of every SDS in your library — and the legal requirement isn't "read Section 8," it's "assess every chemical hazard in your workplace, choose PPE accordingly, and certify in writing that you did it." For a business with forty or sixty chemicals, doing that by hand means opening every document, finding Section 8 in each, and assembling the results into a defensible assessment. It's exactly the kind of task that gets started, half-finished, and abandoned.
This is the workflow SafeSheet is built around. As SDSs enter your chemical inventory, the Section 8 data — exposure limits, recommended glove materials, eye and respiratory protection, skin notations — is available at the point of decision: when you're outfitting a work area, when you're writing the hazard assessment you have to certify, and when a worker needs to know what to put on before handling a product. The regulation doesn't change. What changes is whether the protection information reaches the person making the decision, instead of sitting unread in Section 8.
The Bottom Line
Section 8 of every Safety Data Sheet is a PPE answer key written specifically for the chemicals in your workplace. It tells you the exposure limits, the engineering controls that should come before PPE, and the gloves, eye protection, and respiratory protection a worker actually needs. OSHA doesn't just suggest you use it — it requires you to assess your chemical hazards, choose PPE based on that assessment, and certify the assessment in writing.
The mistakes that hurt people are specific and avoidable: the glove material the chemical passes through, the dust mask that became an elastomeric respirator without the program to support it, the outdated PEL treated as a safe ceiling, the skin notation nobody read. Every one of those answers is already written down. The only question is whether your protection decisions are coming from Section 8 — or from a guess.
SafeSheet maintains your chemical inventory and SDS library and surfaces Section 8 protection data at the point of decision, so the gloves, eye protection, and respiratory requirements you need are a filter on documents you already have — not a research project.
