I **HATE** that word. To me, adequate means “getting by”. When it comes to ventilation, all of us should be striving for excellence. Adequate is not enough.
Ventilation systems for lampworkers have to be absolutely the best, far beyond adequate.
Some folks advocate using ventilation systems that move 100 CFM per square foot of hood coverage on overhead hoods. That is not even adequate. Some companies sell hoods that don’t even meet the 100 CFM criteria. Some folks say doing all those numbers to calculate your ventilation system is a wast of time and energy (“I question the need for all those calculations” I believe is the one of the phrases I have seen posted by someone).
I am beginning to believe that our first lampworking safety incident is not going to be a propane accident as I’ve assumed it would be, but it is going to be ventilation related. (And, it has. There has been a fatality in New Mexico last year, which may very well have been ventilation related.) “Some folks” are far too complacent and far too willing to accept the easy way of doing things.
I am tired of hearing about the “easy way”. It has to be done the RIGHT WAY or someone is going to get hurt. And the RIGHT WAY involves doing some skull sweat and running a calculator or an Excel spreadsheet. The RIGHT WAY involves following the CODES…”some folks” are quick the NFPA codes for propane but are will to totally ignore the ventilation codes….sort of makes you wonder why, doesn’t it?
And, if you have someone in your household who is “respiratory impaired” (with asthma, reactive airway disease, COPD, or any other respiratory related problem), having anything other than excellent ventilation is like handing a sparkler to a 4 year old: something bad is going to happen.
