The Best Fall Protection Harnesses: 4 Compared (and One to Skip) · Tools & DIY
3M DBI-SALA Tongue Buckle Positioning Belt with Hip Pad
A perfectly good positioning and restraint belt that is not fall arrest equipment and is bought by people who think it is.

The Best Hard Hats: 4 Compared (and One to Skip) · Tools & DIY
3M SecureFit Safety Helmet X5000 (X5001-ANSI)
A well built climbing style helmet that a lot of people buy as a Type II upgrade, which 3M's own bulletin says plainly it is not.
Why we skip it: 3M's technical bulletin states in bold that the X5000 series does not meet ANSI Z89.1 Type II head protection requirements, and that its EN 12492 test results are not equivalent to Type II front, side or rear energy absorption.

The Best Reusable Respirators: 4 Compared (and One to Skip) · Health & Wellness
3M Secure Click Half Facepiece Reusable Respirator HF-800 Series
The best-engineered mask in this comparison, and the wrong one to buy for a home shop, because its filters are the hardest here to walk in and buy.
Why we skip it: It is approved only with 3M Secure Click D8000 cartridges and D3000, D7000 and D9000 filters, a family stocked by industrial distributors rather than ordinary retailers.
