As Clear as Glass

For a change, look at glass (or plastic), not through it. In small lettering, you might see some letters and numbers. Markings like “ANSI Z97.1-2015” and “American National Standard Z97.1-2015” denote compliance with testing requirements that assure the glazing materials used in buildings are safe.

Piping & Instrumentation Diagrams (P&IDs)

It's not always easy to know where piping systems go or contain, so piping & instrumentation diagrams show the interconnection of process equipment. Standard symbols can be found in ANSI/ISA 5.1-2024. These drawings can represent:

-centrifugal pumps

-vacuum pumps

-gear pumps

-controllers

-controller valves

-pressure indicator control

-converters

-condensors

-furnaces

-boilers

-motors

-reducers

-separators

CAUTION, DANGER, WARNING

Recognize this symbol? ANSI Z535.4, the American National Standard for product safety signs and symbols, defines it as the safety alert symbol, and this specific color scheme can be accompanied with the signal words CAUTION, DANGER, or WARNING.

You might also see the symbol in different colors. Following the standard, there is also:

-safety white triangle, safety red exclamation mark, safety red background: for use with DANGER

-safety black triangle, safety orange exclamation mark: for use with WARNING

-safety black triangle, safety yellow exclamation mark: for use with CAUTION

What Goes Into a Table of Specifications?

Since it can be hard to decide what questions to include on a final exam, certification courses can create a table of specifications.

This two-way chart identifies the format and content of the assessment, using the learning objectives and the instructional content as a guide.

Creating a table of specifications is a three-part process:

-List the general learning objectives across the top of the table

-List the high-level content areas down the left side of the table

-Determine what proportion of the test items should be devoted to each objective and each content area

Laser is an acronym

Did you know that the word laser is an acronym? It stands for:

Light

Amplification

by

Stimulated

Emission

of

Radiation

And it's an acronym because you pronounce it like a word. If you only pronounced the letters, then it would be an initialism (like ATM). But there are some hybrid acronym-initialisms (like JPEG).

Lasers as a concept trace back to "heat rays" in War of the Worlds, which H.G. Wells published 19 years before Einstein theorized the phenomenon of "stimulated emission."

Hardhats can trace origins to:

-The Boar's Tusk Helmet in Bronze Age Mycenae (~17th Century BCE)

-The Medieval Kettle Hat

-Worker hats smeared with tar and dried in the sun (~1900)

-An industrial hardhat allegedly created by Franz Kafka for the Kingdom of Bohemia (1912)

-The Brodie Helmet (or doughboy helmet in the US) used by soldiers in WWI

-The Hard Boiled Hat, the official first industrial hardhat invented and put on the market by E.W. Bullard (1919)

Demolish, Don't Destroy

Demolition might sound antithetical to construction, but the two function together well. To make way for new construction work on existing structures, demolition is often necessary. Although it is the opposite of construction, worker safety in demolition remains top of mind.

10 things you should know about the Oldowan Industry

It was the very first standard practice ever.

It was the first form of technology.

It began 2.6 million years ago in Tanzania (at the start of the Old Stone Age)

It involved striking a core (a rock) with a hammerstone (another rock). The core would break, leaving behind flakes, choppers, and scrapers.

The flakes, choppers, and scrapers were used essentially as Stone Age knives, cutting flesh from bone to prepare meals.

The Oldowan Industry spread throughout Africa, Asia, and Europe.

It was used by various human ancestors, including Homo ergaster and Homo habilis.

It was largely replaced by the Acheulian Industry 1.8 million years ago, which was characterized by hand axes.

We know about it through archaeological evidence uncovered throughout Europe, Africa, and Asia, such as hammerstones with battering along their surfaces, and flakes that came from the same core.

Even though the Acheulian Industry was more advanced, some places still used Oldowan techniques up to 250,000 years ago.

A Quick History of Elevators

You might not think about elevators much, but they've been getting people to where they need to go for a long time, and standards have been making sure that we reach those destinations safely.

The most concise history of elevators possible:

Archimedes invented the first elevator in 236 BCE.

The Romans used elevators in the Colosseum for lions and other animals to emerge from below the floor.

In 1743, King Louis XV had the "Flying Chair" in his palace in Versailles, which is considered the first passenger elevator.

The Industrial Revolution sped up the development of elevators with hydraulics and later steam power.

In 1854, Elisha Otis and his sons debuted an elevator that didn't drop if its cable snapped.

The advent of electricity saw passenger elevators (and taller buildings) in the early 1900s.

In 1921, ASME A17.1 was first published, and, with the help of periodic updates, this elevator code has kept us safe ever since.

You insert a coin or bill or swipe your card, and you get a dispensed soda or other item. But things are more complicated on the inside of vending machines.

The standard for vending machines, NSF/ANSI 25-2021, calls for materials to resist wear, but also penetration by vermin and the effects of foods, heat, cleaning compounds, sanitizers, and other substances that may contact the materials during use.
