The term pheromone was coined in 1959 to describe chemicals released by insects to trigger hard-wired behaviours in other members of the same species. For many years, it was assumed that humans did not produce or respond to any of these types of pheromones. More controversial still are claims that pheromones are involved in human sexual attraction.

Harvard Medical School is beefing up lab security after six researchers got sick off poisoned coffee back in August. The toxicology reports came in recently, according to Bloomberg, and the chemical culprit was sodium azide, which turns into a toxic gas when it's mixed into water. The good news is that none of the six died. The bad news: Nobody seems to know how this stuff got into the communal coffee pot to begin with. And while a whodunnit poisoning mystery is not exactly what Wired had in mind when it listed "Grad Student" as #6 on its top 10 list of Best, Most Dangerous Science Jobs, this incident certainly does nothing to bump that job off the list. Not to mention the fact that, given the lab environment, you have to wonder whether the poisoning was even intentional at all...or whether somebody simply didn't wash their hands well enough before making a fresh pot. From Wired: Grad student Even the most mundane job in science is hazardous if you don't know what you're doing. Grad students in labs around the world are in constant danger of, well, screwing up. In 2004, a Texas A&M student, for example, was cleaning up a laboratory when a jar of chemicals he was handling suddenly exploded, leaving him with severe lacerations and burns....Posted by on under web slings, osha rules, chart catalog, optis, email sales, nyl, nice job, choker, hitches, power tool, rigging, polyester, nbsp, chemicals, amp |
Synthetic slings offer a number of advantages for rigging purposes, cost, convenience and strength. We wanted to cover some of the basics by highlighting these 3 videos that do a really nice job of explaining Stren-Flex Synthetic Slings.
The most commonly used synthetic web slings are made of nylon or polyester; each performs better in regards to certain chemicals and stretching. Rated loads (capacities) for single-leg vertical, choker and basket hitches all vary greatly by width and ply. Here is the chart catalog to see all the options for the different types of slings. Also here is the link to the OSHA rules and regulations regarding synthetic web slings. If you have any questions on the topic give the pros at Ohio Power Tool a call 800-242-4424 or email sales@ohiopowertool.com with any questions.
