New security measures were enforced as students of Santa Fe High School in Texas returned for the new school year Monday.The security changes come after a student opened fire on May 18, killing 10 students.The most noticeable security addition: metal detectors. Other renovations at the high school include the installation of bullet-proof glass, a secure entrance vestibule and even panic buttons in the classrooms. Interior doors were upgraded to lock from the inside and outside and 500 security cameras were installed district wide. Additionally, the school hired extra police offers, five of which will work fulltime.“Well, it's a very typical reaction from what we’ve seen in a lot of schools in the wake of spring of ’18,” says Amy Klinger.Klinger, a school safety expert with The Educator’s School Safety Network, says on one hand she’s glad to see more schools like Santa Fe investing in new measures, but she cautions money also needs to be spent on the teachers, too.“Are we combining buying stuff with actually training people?” asks Klinger. “Probably a single point of entry is a good idea, but not if you haven't provided people with training on how to screen visitors who are coming in.”Since teachers themselves are the first line of defense, The Educators School Safety Network is urging all schools to consider training faculty to better recognize out of ordinary behavior.“We know that anywhere between 80 to 85 percent of all perpetrators are students in that school, so who is working with those students? Educators,” says Klinger. “So, we need to invest in those people that see those kids every single day and to give them tools and resources and training to be able to pick up on students who are at risk.” 1739

He won three regular Tonys, plus one for special achievement, as well as a Pulitzer and the Mark Twain prize for humor.Simon's successes included "The Sunshine Boys," ''Plaza Suite" and "Sweet Charity." Many of his plays were adapted into movies and one, "The Odd Couple," became a popular TV series. 750

New spikes in COVID-19 cases have reinforced the importance of basic disinfecting and cleaning our homes to stop the novel coronavirus spread.But how do we know that the cleaners we have are effective in killing COVID-19 and other viruses?"One of the things that's important to know: Is there is a lot of good evidence that the coronavirus is one of the easiest types to kill?" said Texas A&M University - Corpus Christi Associate Professor of Chemistry Dr. Patrick Larkin.Yes, he said. He believes most household cleaners will destroy the virus.He said the best chemicals to use for disinfecting are, bleach, ammonia, and alcohol. However, he does warn that precautions be taken with alcohol concentrations."For example with isopropyl alcohol, you need at least a 50 percent solution; and ethanol [or ethyl] alcohol, you want at least 60 percent," he said.But, take note -- there also are guidelines for how you should clean, so it can be the most effective."CDC guidelines say you should clean the surface with soap and water first, and then apply your sanitizing or disinfectant solution," said retired Certified Industrial Hygienist Tom Samson. "Leave it on for at least one minute, and then you can rinse it off."Samson said not all household cleaners are the same, and do not have the same contact-surface time that is required. He recommends reading the labels of the cleaner you intend to use.Larkin and Samson said it is easy to make your own cleaners at home. However, be cautious about mixing chemicals, and be aware what you are cleaning with."The chemistry of mixing a chlorine-based cleaner with an ammonia-based cleaner can be deadly to those in the immediate area," said Samson. "The reaction of these two cleaners is to release chlorine products into the surrounding environment, in some cases, enough to cause severe injury or death. People need to know to get out of the area if this reaction happens and take their kids and pets with them!"Samson notes the Environmental Protection Agency also has a list of cleaners that will kill the novel coronavirus.This story originally reported by Chelsea Torres on kristv.com. 2149

  

New York is adding new measures to prevent people from dying while taking selfies at a waterfall in the Catskill Mountains.The picturesque Kaaterskill Falls is one of the most visited spots in southeast New York state. However, capturing the perfect photo for social media turned fatal for several people.“I cringe, when someone is where they shouldn’t be,” says Peter Innes with the New York Department of Environmental Conservation. “Because they are just too close to the edge.”Four deaths in the past several years occurred due to the victims being too close to the edge, while taking or posing for photos. Officials say it’s now considered one of the riskiest activities at the park.“A lot of people would think about ice climbing or rock climbing, back country skiing,” says Robert Dawson, a forest ranger. “It’s actually picture taking, because everyone can do it now.”The park sees tens of thousands more visitors annually than they did just a couple decades ago. A lot of that is due to visitors posting photos on their social media platforms, attracting new visitors seeking similar photo ops.“Or they’ll put it on YouTube, and they wanna see how many hits they can get on it,” explains Dawson.“So, then they wanna make those really cool videos. That’s where they’re willing to take that extra risk.“Then people will see that and be like, ‘I wanna go up there.’” Two of the most recent deaths—in 2016—occurred after the state had already made safety changes.Officials added a staircase to prevent slipping, as well as fencing to keep people from the edge. However, people continued to walk around it despite the obvious park signage.   “We realized there was a problem because of the continued fatalities,” says Innes.Innes helped draft new regulations that went into effect this month.“People are now not allowed to get within 6 feet of the cliff’s edges themselves,” says Innes of the new policy. “They also can’t swim within 150 feet of the top of the falls.”Now, rangers like Dawson have the authority to ticket and even forcibly remove anyone putting themselves at risk.“Before I was just like, ‘Hey, I really don’t want you to do this,’ and some groups will listen some are like, ‘Hey, it’s a free country,’” says Dawson.If he could offer just one piece of advice to Instagram-happy trail goers, Dawson says, “You can still get that great picture; you can do it 10 feet away from the edge and you’ll get the same effect.” 2470

  

NEW YORK (AP) — “Sesame Street” has always pressed for inclusion. Now in the wake of the national reckoning on race, it’s going further — teaching children to stand up against racism. Sesame Workshop — the nonprofit, educational organization behind “Sesame Street” — will air the half-hour anti-racist special “The Power of We” and hopes families will watch together. The special defines racism and shows how it can be hurtful. It urges children who encounter racism or hear someone else be the victim of it to call it out. Gabrielle the Muppet advises: “When you see something that’s wrong, speak up and say, ‘That’s wrong’ and tell an adult."“Sesame Street has the ability to entertain children while explaining complex issues like no other program and equips families and caregivers with the support they need to have empathetic conversations,” said Kay Wilson Stallings, Executive Vice President of Creative and Production at Sesame Workshop. “We believe that this moment calls for a direct discussion about racism to help children grasp the issues and teach them that they are never too young to be ‘upstanders’ for themselves, one another, and their communities.”The special will stream on HBO Max and PBS KIDS starting Thursday, October 15, PBS says. The special will also be aired on PBS stations throughout the United States. 1342
