Catalogs with A+ tech information
The catalogs with high-quality and expensive products can also be loaded with high-quality technical information.
DISCLAIMER: Not making recommendations or have any interest in company. I do use some of their products.
At above link – hopefully it hyperlinks – is a half page chart titled “Different Lights For Different Hazardous Locations”. This tech info is super because it is to the point and product examples explain and clarify.
Recently I posted a link to Forestry Suppliers of Jackson, Mississippi with their tech info in catalog.
Some of the industrial safety products catalogs have charts on eg explaining the catagories of face masks like the 3M N-95 to the P-100.
As I get to my pulp catalogs, will post those with decent web links with tech info. Again: I am not “pushing” ant company or products.
