Stay Safe: Essential Precautions
Hydration and Cooling
Drink plenty of water throughout the day, avoiding sugary drinks, alcohol, or excessive caffeine. Limit outdoor activities, especially from 10 AM to 6 PM, and seek shade. If your home lacks AC, utilize public cooling centers. Check the LA County Department of Public Health website or dial 2-1-1 for locations. Wear lightweight, loose-fitting, light-colored clothing.
Protecting Vulnerable Groups
Prioritize the safety of the elderly, infants, young children, individuals with chronic medical conditions, and outdoor workers. Check on elderly neighbors. Never leave children or pets in a vehicle, as temperatures rise rapidly. Ensure pets have water and shade; limit their walks to cooler times, checking pavement heat.
Community Impact and Environment
Energy Conservation & Fire Danger
High temperatures strain the power grid. Conserve energy, particularly during peak hours (4 PM to 9 PM). Adjust thermostats, turn off unnecessary lights, and run appliances off-peak to prevent outages. Additionally, the extreme heat, low humidity, and dry vegetation elevate wildfire risk. Ensure defensible space, avoid spark-causing activities, and report any smoke or fire to 9-1-1 immediately.
