  • It is kind of hilarious that airplanes are seen as being safe and reliable, when if they were given the same factor of safety as most other consumer goods, they’d never get off the ground from being too heavy.

    I do NOT recommend you do this, but if a ladder says it is designed for 300 lbs, then it should carry 1200 lbs. 4X is a fairly common factor of safety for things like ladders where people’s lives are in jeopardy. Most other items are usually 2X. (I want to point out that there are qualifications to this… static loading and dynamic loading are totally different things. Also a simple point load is not the same as a cantilevered loading condition. A new piece of equipment is not the same as one abused on the job for the last 10 years. All these things will dramatically affect safety ratings for things)













  • I use my electric hair trimmer maybe once a week and then if I want it to be closer I use a manual razor. That blade had probably been in there for at least 6 months. Maybe 2x that. But It isn’t a fair assessment because with a beard and mustache I only need to shave my neck and cheeks. If you want to keep your blade from getting dull, keep it dry and away from water as much as possible. Rusting of the edge will dull it fast. And metal rusts quickly on edges.
