I would ask them to clarify what exactly they think the hazard is, a chain simply being at an angle is not necessarily "side loading". Side loading refers to the axis of load through a piece of rigging equipment being different than what was designed by the manufacturer, sort of like how an egg...

I do not have a lot of experience with LN2 but to my understanding once you get to that level it is strictly cryogenic jets. Essentially just a valve and a diffuser. There is no machine really to speak of.

I know it is said all the time but this is really one of those cases where an engineer is needed. I deal with industrial fall protection and trusses are tricky to work with, unlike I beams they are very geometry dependent and are designed for a generally distributed load. They can have radically...

The way I am visualizing your problem I think bringing the rail towards the spots in a U shape might give you clearance to do what you want. Leave the platform as it is and just move the guard rail in front of the spot in until the body of the spot clears it. Then swoop the guardrail back out in...

I think it started shortly after the introduction of the grounded receptacles. Mike Holt's electrical industry forum has knock down drag out fights on the topic dating back to at least 2006. About every 2-3 years somebody makes a new post and after about 6 pages it gets locked with nothing being...

It may be worth doing some thermal testing as well to see if you actually need that much cooling. It is possible that the cooling system was not actually performance engineered and they just installed what ever fan was the cheapest at the wholesale market that day and the fan may be more...

They do, however 1926.431(g)(3) requires that the provisions of section 1926.502(d) be followed for all fall arrest systems on scaffolding. 1926.502(d)(15) contains the requirement that all fall arrest anchorages be capable of supporting 5000lbs. Now given that this is potentially indoors a...

Adding to that, OSHA requires a fall arrest anchor point to be capable of withstanding 5000lbs of force. A mobile scaffold is not likely to meet that requirement especially outside it's support envelope.

The short answer is that it doesn't. I can not find any listing or recognition in the documentation.

If you are willing to go to dry ice there are a number of good Dry Ice/water foggers out there like the LeMaitre Pea Souper. Hang time is not super long but once the ground layer gets cold you can get 10sec or so

What do you need for hang time? Generaly a water vapor fog will only last a few seconds

Fair enough, I was thinking from the point of not needing a software update.

I will be the odd man out here and suggest another analog mixer like the Mackie 3204VLZ. Predictable, affordable and low maintenance. A 32ch board might even be overkill if they dont have any wireless. BillESC has a used 24ch Onyx for sale that would make a great board. If all they have is a...

If you only need it to open on its own and can reset it manually, I would try some gas springs. They would give it that slow magical opening. The tiny ones that are used on tool box lids might be just enough if the doors move easy.
