This is cool, I didn't realize there are so many. A couple interesting ones: Warning that a bull is in the area: https://en.wikipedia.org/wiki/File:ISO_7010_W034_warning;_bu... Don't wear gloves (any idea when this would be the case? Usually it's don't wear a specific kind (like latex vs rubber) of glove): https://en.wikipedia.org/wiki/File:ISO_7010_P028.svg

Gloves can get caught in moving machinery. If your hand is inside the glove, your hand, arm, or maybe your whole body might also get violently yanked into that machine along with the glove.

Slippery surface exists because of stupid architects / builders / customers ordering buildings. In Norway, there are a bunch of grocery (and other) stores that put those signs out when it's raining or snowing outside, i.e., the floor is likely wet. How about thinking upfront and choosing a non-slippery floor material, even if it doesn't look "fancy".

What do you suggest? I think main considerations are cost, ability to keep clean and durability.

There are some ways to make concrete anti-slip:

Cheap, can pressure wash, if you make the appropriate grooving to allow thermal expansion it will last, but is easy to repair anyway. Can dye with any color you want too.

If you want an environmental-friendly alternative, you can do the same with clay mixed with some binder.

To prohibit the use of gloves when operating a machine with drawing-in hazard [1] [1] https://www.iso.org/obp/ui#iso:grs:7010:P028

Indeed. I run a university fablab/machine shop and we prohibit work gloves on all rotary tools (lathes, mills, press drill, bench grinders) and band saws due to drawing in risk. Not just gloves, but all long sleeves, long hair, jewelry, watches, etc.

We do allow thin nitrile gloves in cases where someone would want to avoid skin contact with eg coolant or cutting oil.

See this 2011 accident at Yale where someone died when their long hair got wrapped up in a lathe. Stuff of nightmares.

I don’t understand this one: M043 — start the water spray for the lifeboat (lifeboat launch sequence) Why do you spray a lifeboat with water?

I guess it's not used to spray the boat, but the water surface. I'm no expert on this matter, but I think it breaks surface tension somewhat.

I have seen people disturb the water in a pool before a high diver jumps, so I think this applies here aswell.

118 CHF (123 USD) to have warning signs... I'm glad that the UN didn't go with these, since interoperability of safety symbology should not be restricted to everyone but poor people I just wish the UN's efforts went further than just chemicals

> 118 CHF (123 USD) to have ...

I see its time for the weekly reminder that one does not need to purchase standards directly from ISO.

What you do is you go buy the "regionalised" (a.k.a. "EN-ISO") version which, for all intents and purposes, is exactly the same document.

EN-ISO versions of ISO documents are available at far, far lower prices.

See for example the online shop at the Estonian Centre for Standards and Accreditation[1]. You don't have to live in Estonia or Europe to buy there.

From a bit of looking around, I suspect it may applicable for lifeboats used in oil/gas applications where the lifeboat could be launched into waters engulfed in flames from burning oil/gas on the surface of the water. There is a video demonstration at [1].

Even though people working in the proximity of a fire resistant lifeboat would already be comprehensively trained to operate said lifeboat, perhaps they've found that people forget and need a reminder to turn on fire suppression sprinklers in the... heat of the moment.

From what I could find lifeboats have sprinkler system which pumps water over the outside of lifeboat for safer passage through water surface fire.
