Of all PPE sizing challenges, accurate sizing for respirators is the most critical. Confusion sometimes occurs because respirator sizes are given descriptors (small, medium and large), but these generally do not relate to any measurable value. Respirators are made with the assumption that most people’s faces and heads have about the same width and length. This means that a medium size will fit approximately 70 percent of the adult population. Small and large sizes are made for a minority of the population. People who need these sizes generally know from their experience buying hats or prescription eyewear that their face and head size falls outside the norm. The only way to ensure the correct size for tight fitting respirators is to conduct the required fit testing.
By the time we reach adulthood, most of us have figured out how to find a pair of comfortable shoes, but in PPE, overshoes/overboots sizing can be confusing. Most overshoes/overboots are sized to fit men, to fit over the shoes being worn underneath and to correspond in size. For example, a size 10 overshoe should fit over a size 10 shoe.
Women’s to Men’s Shoe Sizing Conversion
When converting women’s shoe sizes to men’s shoe sizes, you need to size down two whole sizes. For example, a women’s shoe size 10 is a men’s shoe size 8. Also bear in mind that men’s footwear tends to run wider than women’s footwear.
Men’s International Shoe Sizing Conversion Chart
When converting a men’s shoe size to the correct U.S. shoe size, use the following chart. For example, a men’s European shoe size 44 is a U.S. shoe size 10.5.

It is important to know how to measure the hand to get a proper fitting glove. Measuring the hand for correct fit will give the employee the best possible protection without compromising the task, duty or safety of the wearer. There are two suggested ways to find the correct glove size. One way is to measure the width of the hand — measure around the hand (a dominant hand measurement is preferred) with a tape measure as shown below. The dominant hand will be the right if you are right-handed and left if you are left-handed.
If the gloves you are purchasing come in numbered sizes, you can relate the measurement directly to the numerical size listed for the glove. For example, if the measurement taken is exactly eight inches (203 millimeters) then you would select a size eight glove. To avoid hand fatigue, order the next larger size for all measurements that are not exact inch/millimeter measurements. If the gloves you are purchasing come in extra-small (XS), small (S), medium (M), large (L), extra-large (XL) or double extra-large (XXL), use the table below to translate the inch/millimeter measurement.

- Class 00 – Protects workers up to 500 VAC and 750 VDC
- Class 0 – Protects workers up to 1,000 VAC and 1,500 VDC
- Class 1 – Protects workers up to 7,500 VAC and 11,250 VDC
- Class 2 – Protects workers up to 17,000 VAC and 25,000 VDC
- Class 3 – Protects workers up to 26,500 VAC and 39,750 VDC

If the wearer is not using electrically insulated gloves or any other electrical protective clothing or tools, it is likely that the Class E is not a necessary requirement to meet. In such cases, the benefits of a Class C Vented hard hat, such as comfort and reduced fatigue from heat exposure, will help improve output from the worker.
As a general guideline, it is recommended to replace the suspension annually and the hard hat every five years regardless of outside appearance.
While OSHA has no specific provision for an expiration date, manufacturers are allowed to determine if their equipment expires on a specific calendar date.
Hard hat lifespans may vary depending on the conditions of each work site. Hard hats subjected to more wear and tear or used outdoors in direct sunlight may need to be replaced more frequently. Daily inspections are the best way to determine when to replace a hard hat shell, suspension, or the entire unit. The suggested replacement is based on service life (Based on when the hard hat was placed into service, not the manufacture date).
As a general guideline, it is recommended to replace the suspension annually and the hard hat every five years regardless of outside appearance, but this can vary due to use and job site conditions
Regardless of the length of use, if a hard hat has been struck by a forcible blow of any magnitude, the shell and suspension should be replaced immediately, even if no damage is visible. Dropping a hard hat more than 8 to 10 feet warrants a replacement. Don't take a chance that it "might" be okay because it's not worth the risk. Hard hats are designed to provide optimum protection under normal conditions. ANY impact can substantially reduce the protection offered.
OSHA’s general requirements for PPE are set forth in 29 CFR 1910.132. The specific requirements for head protection (protective helmets) are outlined in 29 CFR 1910.135, which incorporates by reference American National Standards Institute (ANSI) Z89.1-1986, Z89.1-1997, and Z89.1-2003. Both 29 CFR 1910.132 and 1910.135 do not contain provisions that explicitly prohibit painting or the placement of adhesive stickers on helmet shells. However, the employer’s ability to comply with the existing requirements of these standards may be adversely affected by the painting or placement of adhesive stickers on the helmet’s shell.
For instance, OSHA standard 29 CFR 1910.132(a) requires that PPE be “…maintained in a sanitary and reliable condition…” [Emphasis added.] To ensure a helmet is and remains in a “reliable” condition, the helmet must be inspected prior to use for signs of dents, cracks, penetration, and any damage due to impact, rough treatment, or wear that might reduce the degree of protection originally provided and used and maintained in accordance with the manufacturer’s instructions. Paints and stickers may eliminate electrical resistance and – depending on the location and quantity – conceal defects, cracks, penetration, and any damage that would be otherwise readily identifiable during the employee’s inspection to ensure reliability. Another concern is that paints, thinners, and solvents, as discussed in Appendix A of ANSI Z89.1-2003 and the appendices of the 1986 and 1997 versions, can also attack or damage the shell of a helmet and reduce protection.
For these reasons, painting or applying stickers must be performed in accordance with the manufacturer’s instructions, unless the employer can demonstrate that the altered protective helmet is equally as effective and protective as those meeting the requirements of Z89.1. Protective helmet manufacturers usually provide very specific instructions regarding paints, stickers, or decals that will not negatively affect the performance of a protective helmet.
OSHA would consider painting or placing adhesive stickers acceptable if the manufacturer authorizes the alteration or the employer can demonstrate that the reliability of the helmet is not affected by the paint or the adhesive on the stickers; and the paint or placement of stickers would not reduce the ability to identify defects (i.e., use of see-through stickers) or other conditions that would indicate a reduced reliability.
