Heat-Related Outages

Current Status

HEAT Safety messages

Heat illness is a serious medical condition resulting from the body’s inability to cope with an environmental heat load, and may include heat cramps, heat exhaustion, heat syncope, or heat stroke.
Signs of Heat Illness 
  • Nausea 
  • Dizziness, fainting, paleness 
  • Severe headache 
  • Thirst 
  • Weakness or unusual fatigue 
  • Irrational behavior 
  • Profuse sweating or no sweating. 
Anyone who works in extreme hot or humid environments may be at risk for heat illness. It's important to keep your body temperature within a safe limit.
Protecting Yourself from Heat Illness
  • Discuss heat illness prevention during tailboards. 
  • Wear light-colored, loose-fitting, breath-able clothing such as cotton. Avoid synthetic fabrics. 
  • Apply water-resistant sunscreen (SPF 30 or higher). 
  • Schedule your heavy work during the coolest part of the day and take adequate rest breaks. 
  • Don’t wait until you are thirsty to drink water. Drink cool, fresh water throughout the day (four, 8-ounce cups per hour). Choose water over caffeinated drinks. 
  • When working outdoors, ensure that an adequate amount of water is available for each crew member for the entire shift. 
  • When the outdoor temperature in the work area does not exceed 85ºF, ensure shade is available and provide timely access to shade. However, shade is required to be present when the temperature exceeds 85ºF. 
  • If the work is considered “highly mobile,” or conditions make shade infeasible, equivalent, alternate procedures may be used for compliance. Please contact your Safety Specialist for guidance. 
  • Inform your supervisor immediately if the heat is causing you to feel ill and take a cool-down rest in the shade for a period of no less than five minutes to protect yourself from over-heating. 
First Aid 
When you observe signs of heat illness, stop all activity and relax in a cool, shaded place. 
  • Drink water, clear juice, or a sports beverage to replenish minerals in your body. 
  • Apply cold packs to your forehead, under your arm pits and behind your neck and knees. 
Call 911 or seek medical attention if you or a coworker experiences headache, dizziness, nausea, or loss of consciousness. 
  • Move victim to a cool, shaded area. 
  • Keep victim lying down.  
  • Loosen tight clothing. 
  • Apply ice packs or cold packs. 
  • Do not give liquids to an unconscious or semi-conscious person. Liquids can be provided if victim is awake and lucid. 
  • Inform your supervisor immediately.
Medical Baseline Customers 
If the California Independent System Operator (CAISO) declares a Stage 3 Emergency and requires power reduction, SCE will automatically contact Medical Baseline customers with a pre-recorded telephone message. 
The message warns of the strong likelihood of a rotating power outage, and recommends that you take any necessary emergency precautions. Because SCE could only receive 10 minutes’ notice, Medical Baseline customers may not hear about the outage before it occurs.

Safety around Power during Outages 

Stay away from downed wires. If you see a wire down, call 911.
If you are using generators, do not run them inside your home.  There is a danger of carbon monoxide poisoning from generators used indoors.  Plug appliances directly into the generator, do not plug the generator into the 220v line, as this could cause backfeed which could electrocute crews working on the lines.  
Stay away from crews working in or around lines or vehicles.  They are working as quickly as possible and they should not be distracted from this dangerous work.
