SAN DIEGO (KGTV) - Explosions in a fake Mission Valley city teach the public and West Coast gas employees how to save lives.Training Supervisor Scott Hazlett says it's as easy as calling 8-1-1 two days before you plan to do any digging on your property.The importance highlighted after a Murrieta home exploded Monday from an ignited natural gas leak, killing one man and forcing four families out of their homes."There's a lot of potential sources of ignition, cigarette liters, cellphones, cameras, drones anything like that can actually you know ignite the gas, and create what you saw here today," Hazlett said after demonstrating what 60 lbs. of natural gas pressure lit on fire looks like. Onlookers described it as a fireball, with heat radiating feet in all directions.The lines are generally between two and three feet underground. "I wouldn't say anyone's safe... Anytime you're moving the earth other than with your hand any kind of shovel, you need to call that number," he said.An SDGE employee will come out within two days after the call, mark where the natural gas lines are around your property, and do it all for free.Hazlett said accidents happen often and the number of calls for repairs skyrocketed in 2018. "Last year we had almost 300 that's almost one every single day," he said.He pointed at a display showing various ways pipes were punctured, stakes for Concrete pouring, rebar, a tree root, and a piece of heavy digging equipment raked a steep pipe.Any of those breaks could produce the tragedy that happened in Murrieta. "Public safety is #1, it's the biggest thing we have, it's the only thing we have," He said.Starting in July 2020, a new board will issue citations to those who do not call 8-1-1 in advance of digging on their property. Fines could cost up to ,000. 1809

SAN DIEGO (KGTV) — Even though Americans could start getting vaccinated in days, experts say people who get the shot will still need to wear masks and practice social distancing until scientists can answer a key question: whether immunized people can continue to spread COVID-19.The clinical trials by Pfizer and Moderna showed the two vaccines were about 95 percent effective, but what that really means is they were 95 percent effective at preventing COVID-19 symptoms.The trials did not measure whether vaccinated volunteers got infected without showing symptoms.That means “it is possible and conceivable” that immunized individuals could still be silent spreaders, said Dr. Christian Ramers of Family Health Centers of San Diego. “You’re not going to get sick, but you still get an asymptomatic case, pass it on to your grandmother and kill her.”Both the Pfizer and Moderna vaccines are injected into the arm muscle to stimulate production of antibodies. From there, the antibodies can quickly get to the lungs to fend off severe infection. But experts say the antibodies may have less access to the nose and throat, the primary entry points for the virus.Some studies have suggested that people without symptoms can still have high enough levels of coronavirus in their nose to infect other people.“The vaccine is doing something to prevent disease. We don't really know yet if it prevents transmission,” said Dr. Ramers. “So we have to fall back on all those fundamental things like distancing, masking and washing hands.”Still, experts say there are encouraging clues that vaccinated people may be less contagious. A study in October found antibody levels in the blood were similar to levels in saliva.AstraZeneca had volunteers in its trial test themselves for signs of infection and reported there were fewer asymptomatic cases. However, the company has not yet provided details and its vaccine relies on different technology than Pfizer and Moderna’s mRNA candidates.Until we know more, doctors say vaccinated people will have to keep wearing masks -- potentially until there we achieve herd immunity.“There is modeling to suggest that it will be summer until we reach the point where there are enough people vaccinated that this curve of new cases really starts to go down,” Ramers said.There’s a chance we could get good news before then. Both Pfizer and Moderna say they’ll start testing their volunteers’ blood to reveal if they got infected after vaccination.Pfizer plans to examine a subset of its volunteers. Moderna said it will analyze blood from everyone in the trial.Moderna said it will take several weeks to produce results. 2656

SAN DIEGO (KGTV) - Hate crime charges were filed Monday against the Little Italy man accused of attacking three Muslim women wearing hijabs. Kyle Allen, 50, pleaded not guilty to battery in a San Diego courtroom following the Oct. 6 incident. The women were walking on Columbia Street when Allen approached them from the other direction. Witnesses said Allen lunged his shoulder into them, tried to remove one woman's hijab, then hit one of the women. RELATED: San Diego Police: Alleged attack on 3 women in hijabs a possible hate crime "As I got closer I heard him calling her names and telling them to go back to where they came from," a witness who only wanted to be identified as Amy told 10News. Passersby trailed Allen back to his high-rise apartment in Little Italy and called police. San Diego Police said Allen answered his front door while holding a handgun with a silencer. A total of 10 guns were found in Allen's home and seized, investigators said. Allen was arrested without incident.Protection orders are in place for the three women, keeping Allen from contacting them or coming within 100 yards.Allen will return to court Dec. 19 for a preliminary hearing. He faces up to four years, four months in prison if tried and convicted, according to the District Attorney's office. 1300

SAN DIEGO (KGTV) - Dog owners who live in Normal Heights are worried about the future of the off-leash dog park at Ward Canyon.Earlier this month, signs appeared saying the large-dog area would be closed through the end of March 2020. People who use the park say it's because a few neighbors complained about the noise to the local Advisory Committee.Because the large-dog area is closed, all sizes of dogs have been sharing the small-dog area next to it."It's really crowded," says dog owner Christina Ardon. "When people get off work, everyone's over here. It's a little bit of a madhouse.""It's intimidating to smaller dogs," says Jason Douglas-Hiley. "They won't come into the park because they're afraid of the large dogs harassing the smaller dogs."Meanwhile, the City of San Diego has plans to renovate the entire park. Renderings show the area where the large-dog park currently sits would be turned into a community garden. The small-dog park would be expanded.But, City Councilmember Chris Ward's office says there is no funding for that project, and no timetable for when it could be added to the budget.People who use the park say they're afraid it will disappear while the project sits in limbo."To have to wait 2-5 years for them to construct a new park is a lifetime for a dog," says Douglas-Hiley.Park supporters have started a petition, asking the city to safeguard the small-dog area and also fence off a different portion of Ward Canyon for large dogs to use. They're also encouraging people to go to the Adams Recreation Advisory Group meeting on October 22 to voice their concerns.The meeting is at 6 pm, at the Adams Recreation Center (3491 Adams Avenue). 1685

SAN DIEGO (KGTV) - Each year around this time, we marvel as gray whales make their way from Alaska down to Baja, Mexico, to give birth. However, this year's migration started late. "This year, with the migration being so late, a lot of the moms aren't actually making it to the lagoon before they give birth. So we're seeing a lot of these pregnant females giving birth on the migration this year," said Captain Domenic Biagini, founder of Gone Whale Watching San Diego.While the migration is late, Biagini says the whales look much healthier than last year, when many died. "Likely these whales spent a little longer feeding this year to make up for what they didn't get last year, and with less sea ice than normal, they're able to actually go further north looking for food, which then also makes the migration longer," said Captain Dom. Biagini says the calves aren't strong enough to dive, so he's already seen close calls with private boaters speeding by. "The problem is a lot of these grays, especially the moms with babies, are intentionally trying to keep a low profile and people aren't realizing that they're there as they're flying through thee areas. So it's really crucial to be conscious of your speed and surroundings during gray whale season," said Biagini.He says while the newborns are more vulnerable, the moms do a good job keeping a low-profile.They should arrive at their destination in a week or two. 1433
