How to stay cool in a summer blackout

Monday marked the latest test of the state's power grid, with officials urging Texans to conserve energy during peak hours.

The big picture: ERCOT didn’t anticipate any "system-wide outages" as of mid-afternoon, but it's yet another reminder to prepare for potential blackouts in the summer heat.

Here's what you should do ahead of time:

• Fill your car with gas, get cash and stock up on water and nonperishable food items.
• Purchase emergency items like a first aid kit, a battery powered radio and fan.
• Conserve energy usage by rotating reversible ceiling fans counterclockwise, closing blinds and setting your thermostat higher.
• Make a plan in case you need to evacuate, and review cooling center locations.

Here's what to do if you lose power:

• Make sure you, your loved ones and pets drink lots of water.
• Keep curtains closed, especially those facing direct sunlight.
• Use towels soaked in cold water and ice packs on the body to stay cool.
• Circulate the air with a battery powered fan and open the windows at night.
• Take a cold bath or hop in a swimming pool to cool off.
• Keep refrigerator and freezer doors closed to prevent food from spoiling sooner.

The bottom line: Know the signs of heat stroke and heat exhaustion. Check on pets, elderly neighbors and children.
