Technical specifications and typical properties of the 3M™ 4545

The 3M™ 4545 protective coverall is designed to offer an effective barrier against solid particles and liquid aerosols. It is aimed at professionals exposed to dusty or contaminated environments, particularly in the chemical industry, food processing, or during asbestos removal work.

It is made of SMS (Spunbond-Meltblown-Spunbond) non-woven, a multi-layer material that combines mechanical strength with fine particle filtration.

Mechanical resistance

The SMS fabric resists tears, light abrasions, and punctures common in workshops or on construction sites. The seams are covered with a heat-sealed tape to prevent any infiltration at the junctions.

The main mechanical characteristics:

• High tensile strength for a disposable non-woven
• Heat-sealed seams along the entire length
• Elasticity at wrists, ankles, and hood for a secure fit
• Zipper closure with integrated protective flap

Breathability and comfort for prolonged wear

SMS remains more breathable than Tyvek® (flash-spun HD polyethylene) for equivalent protection against dry particles. In practice, perspiration evaporates better, which reduces fatigue during continuous wear.

Key points for comfort:

• Lightweight and flexible material: freedom of movement preserved
• Adjustable hood without obstructing the field of vision
• Flat seams to prevent skin irritation
• Compatible with the simultaneous use of a respirator

FAQ - 3M™ 4545 Protective Coverall

1. What exactly does the 3M™ 4545 coverall protect against?

The 3M™ 4545 is a Type 5/6 protective coverall, designed to block fine solid particles (Type 5) and light liquid splashes (Type 6).

It is particularly suitable for asbestos removal, sanding, powder painting, handling diluted chemicals, or interventions in dusty environments.

2. What is the difference between the 3M™ 4545 and the 3M™ 4510?

Both coveralls belong to the 3M Type 5/6 range, but the 4545 incorporates an attached hood and taped seams, which reinforces overall tightness.

The 3M™ 4510 is a lighter version, without taped seams, suitable for less exposed environments. The 4545 is the right choice when the level of particulate contamination is high.

3. Can the 3M™ 4545 be worn in combination with a respirator?

Yes. The hood of the 4545 is compatible with 3M half-masks and full-face masks, particularly the 6500 and 7500 series.

The fit of the hood around the mask limits particle entry points near the face, which is essential during interventions in asbestos-contaminated or heavily dust-laden environments.

4. Is the 3M™ 4545 coverall reusable?

No. The 3M™ 4545 is a single-use personal protective equipment. Once contaminated, it must be removed carefully and disposed of in accordance with current regulations.

This single-use design ensures that no contamination is transported from one site to another.

5. How do I choose the right size for the 3M™ 4545 coverall?

3M offers the 4545 in several sizes, generally from M to XXL. It is recommended to choose one size larger than your usual size to ensure sufficient freedom of movement during work.

A coverall that is too tight weakens the seams and reduces the actual level of protection in the field.

6. Is the 3M™ 4545 certified for asbestos removal?

Yes. The 3M™ 4545 coverall meets the requirements of the EN 13982-1 (Type 5) standard, which makes it compliant for asbestos removal and encapsulation work in France, in accordance with Labor Code regulations.

Always verify that all of your PPE equipment is consistent with the risk level assessed by your site manager.
