Hey! Is it true that engineers don't say the glass is either 1/2 full or 1/2 empty?
They just say it's the wrong size container.

No it is not true. No competent engineer would make such an ill-controlled and absolute assessment without a lot more information. They would want to know things like:

  1. Is that the maximum volume you will ever want to put in that glass?
  2. Are you going to use that glass to take your coffee with you on the morning commute?
  3. If yes does the glass have a lid?
  4. Will it fit in your cup holder?
  5. What is the potential for expensive vehicle damage if the contents spill out on the car interior when you are driving?
  6. If it has hot coffee in it and it spills on your person what are the chances you will crash and kill or injure yourself or someone else?

Once they have collected that sort of information an assessment of the suitability of the size can be made on a probabilistic basis involving function, risk, and safety. That is also how the public health safety engineers and doctors have assessed the dangers of allowing essentially uncontrolled sale of isocyanate paint hardners. They have determined that with proper labeling and cautions they can be used safely by exercising good judgement and the sorts of PPE that are readily available to the general public.
