Disposable Coverall Types

What are the types of disposable coveralls?

Published June 22, 2026 · Last updated July 27, 2026

Short answer: Disposable coveralls are classed by what they keep out, using a Type 3 to Type 6 system: Type 6 resists light spray, Type 5 resists airborne dry particles, and Types 4 and 3 resist liquid spray and pressurized liquid. Fabric tells you the class — Tyvek and ProShield are particulate and light-splash (Type 5/6), while Tychem is chemical liquid (Type 3/4). Matching disposable coverall types to the hazard is the whole game.

Disposable coveralls look similar on the shelf but protect very differently, and choosing a particulate suit for a chemical job is a silent exposure. Protective clothing is classed by a "Type" system (drawn from the EN 13034/14605 families and labeled by manufacturers worldwide) that ranks how aggressively a liquid or particle is kept out. OSHA's PPE rule, 29 CFR 1910.132, requires body protection matched to the hazard, and the Safety Data Sheet drives that match. This guide is written for safety managers and crews specifying disposable protective clothing. We decode the disposable coverall types, map the major fabrics to them, and work a selection example.

Why this matters.
A Type 5 particulate suit will let a solvent or acid spray soak through and reach the skin, a route of exposure that respirators do not address. OSHA 1910.132 requires a hazard assessment before PPE selection, and for the body that means matching the coverall Type to whether the hazard is dust, spray, or pressurized chemical.

The coverall protection Type system

Coverall Types rank protection from highest number (least demanding) to lowest. The four that matter for disposables:

Types 1 and 2 are gas-tight and generally reusable encapsulating suits, outside the disposable range. Shop disposables in our Disposable Coveralls collection.

The fabric name on the box tells you the protection class:

Higher-Type chemical suits (Tychem) cost more and breathe less, so do not over-spec — match the Type to the hazard.

Particulate vs chemical: the key split

The most important distinction is particulate (dry) versus chemical (liquid). A Tyvek 400 suit is excellent against dust, lead, and asbestos fibers and resists light splash, but it is not a barrier against aggressive liquid chemicals. For solvent, acid, or pressurized-liquid exposure you need a Tychem-class Type 3/4 suit. The same logic that governs chemical-resistant glove selection — match the material to the chemical via the Safety Data Sheet — applies to the coverall.

How to choose a disposable coverall

1. Identify the hazard state. Is the exposure a dry particle (dust, fiber, powder) or a liquid (spray, splash, jet)? This sets particulate vs chemical.
2. Read the SDS for chemicals. For liquid chemical work, Section 8 guides the fabric and Type; a permeation-tested Type 3/4 suit may be required.
3. Pick the Type. Dust to Type 5; light splash to Type 6; heavy chemical spray to Type 4; pressurized liquid to Type 3.
4. Choose features. Hood, attached boots, elastic cuffs, and taped seams raise protection and cost; match them to the task.
5. Size and pair PPE. Allow room to move, and combine the coverall with matching gloves and respiratory protection for full-body coverage.

Worked example: coveralls for two jobs

One contractor runs an asbestos-abatement job and a solvent-spray job. Here is the choice on real SKUs:

1. Asbestos / dust (particulate). A Type 5/6 suit handles fibers and dust — the DuPont Tyvek 400 TY127S hooded coverall or the boot-equipped Tyvek 400 TY122S with hood and boots from the disposable coveralls range; an economy option is the DuPont ProShield 10 coverall.
2. Solvent spray (chemical). Step up to a Type 3/4 chemical suit such as the DuPont Tychem 4000 chemical-resistant coverall or the higher-barrier Tychem 6000; Tyvek alone is not sufficient for solvent spray.
3. Light-duty alternative. For light particulate or splash, the KleenGuard A20 (dust) or KleenGuard A40 (light liquid + particle) and the 3M 4510 coverall are economical.
4. Pair gloves and respirator. Add the right gloves from our chemical-resistant gloves range (using the chemical glove guide) and the correct cartridge via our cartridge color codes reference.
5. For disposable hand protection, match the film to the task with our nitrile vs latex vs vinyl gloves guide, and confirm glove fit with the glove size chart.

Why trust WC Safety

WC Safety is an independent, affiliate-supported review site. It is not a retailer: it holds no inventory, takes no orders, and earns only from qualifying purchases through clearly marked links — which never changes what a product is rated to do. Standards language is taken from the regulation text directly, and ratings are reported as the manufacturer publishes them. We run no laboratory and perform no testing of our own. Where published sources disagree, we say so and plan on the conservative figure rather than the flattering one.

Our methodology

Figures come from the regulation and the published specification, in that order. Derated numbers are calculated, not estimated. Nothing here is presented as a measured result, because we measure nothing.
