As far as the loss being minimal, I have to respond with a resounding no. This is a horrible design flaw and needs to be addressed in future versions of the product. And likely some kind of rebate/refund offered to anyone who purchased the original version.
It’s been hot here in LA and in the last couple weeks I have lost OVER A GALLON of 99% IPA due to this thing having no proper seal. And in the last couple months I’ve lost around 2-3 gallons. No leaks, just evaporation in a heat wave in a shop with no AC.
This is ridiculous, you should have known better when designing the product.
And yes, my shop is also full of dizzying IPA fumes. Hope OSHA does not swing by.
This is basically a standing container of 2.27 gallons of IPA, which has a flash (evaporation) point of 53°F. Many workshops (especially during summer heat waves) can rise to well over twice that.
INHALATION EXPOSURE LIMITS
The OSHA health standards for exposure to air contaminants require that an employee’s exposure to isopropyl alcohol not exceed an 8-h TWA of 400 ppm in the working atmosphere in any 8-h shift of a 40-h workweek (OSHA, 1982); a ceiling of 800 ppm was determined during a sampling time of 15 min (NIOSH, 1976). An estimated 141,000 employees may be exposed occupationally to isopropyl alcohol in the United States (NIOSH, 1976).
The American Conference of Governmental Industrial Hygienists established the value of 400 ppm as the TLV for isopropyl alcohol; as described above, this is the TLV currently recommended in the United States (American Conference of Governmental Industrial Hygienists, 1980, 1983). The permissible concentration of isopropyl alcohol was established by the Japan Association of Industrial Health in 1966 at 400 ppm (Japan Association of Industrial Health, 1971). In the U.S.S.R., the maximal permissible concentration of isopropyl alcohol in a single dose or as a daily average is 0.6 mg/m3(U.S.S.R. Ministry of Public Health Individual Reports, 1971).
Normally the area where my Form Wash is stored is not heavily ventilated, but I’ve had to increase ventilation to reduce IPA exposure risks. Sadly this has drastically increased the rate at which the IPA is evaporating.
Again, I’m dumbfounded that a company with so many amazing engineers and material scientists could overlook something so basic as proper sealing on a 2+ gallon container of volatile IPA. It seems almost impossible to imagine, yet here we are!
