Emergency Lighting on Farms

When the power fails, a barn or shop can go completely dark. Emergency lighting gives people a way to find exits and move calmly, and it is worth planning before the next storm.

Why plan for emergency lighting?

Storms, ice, equipment failures and utility work can cut power with no warning. Livestock buildings, shops and grain facilities may be full of people, animals and equipment when it happens.

Darkness makes every other emergency worse. In a fire, a medical event or an animal escape, being able to see the exit and the path to it saves time and reduces panic. In any life-threatening emergency, call 911.

What types of backup lighting exist?

There are several approaches, from simple battery-powered units to systems connected to a standby generator. Each has trade-offs in cost, upkeep and how long it can run.

Which type fits your farm depends on your buildings, your power source and local requirements. Ask a licensed electrician and your insurer about options, and follow the manufacturer's instructions for any product you install.

• Battery-powered units that switch on when power is lost
• Portable work lights and lanterns stored in known places
• Lighting circuits tied to a standby generator
• Headlamps kept for each regular worker

Where should backup light go?

Think about the path a person would take to leave each building, and light that path first. Then think about places where a sudden blackout would be most dangerous.

Walk each building with the main lights off, ideally during the day with the doors closed, and note where you cannot see. Those spots are your priority.

Think also about people who are not on the farm every day. A delivery driver, veterinarian or neighbor helping in an emergency may arrive in the dark and not know where switches, exits or hazards are. Mark switch locations with reflective tape or a simple sign, and keep entrance areas lit so visitors do not wander into unsafe parts of a building. After any outage, walk each building before turning everything back on, and look for tripped breakers, damaged cords or fixtures that were left in an unsafe state.

• Exit doors and the routes to them
• Stairs and ladder bases
• Animal handling and loading areas
• Shop areas with running equipment
• Electrical panels and generator connections

How do I use generators safely with lighting?

Generators create their own hazards, including exhaust gases, fire and electrical backfeed to utility lines. Never run one inside a closed building, and never connect one to a building's wiring without a proper transfer arrangement installed by a qualified electrician.

Read and follow the manufacturer's manual, and check the guidance from OSHA, NFPA and your utility. Do not improvise connections during an outage.

How do I test and maintain emergency lights?

Backup lighting only helps if it works when needed. Batteries wear out, lamps fail and dust covers lenses.

Set a recurring reminder to test every unit and keep a simple log. Replace batteries and parts according to the manufacturer's schedule, and keep flashlights where people can find them without light.

• Test each unit on a regular schedule
• Record the test date and result
• Replace weak batteries before they fail
• Keep portable lights in labeled spots
• Charge or stock spare batteries

How do I make sure everyone knows the plan?

Walk new workers and family members through the exits and where lights are kept. Practice finding the way out in low light.

Agree on a meeting point outside, and make sure anyone who visits, including delivery drivers and helpers, is told about it. A plan only the owner knows is not much of a plan.

What does a good outage drill look like?

A drill does not need to be elaborate. Pick a calm time, tell everyone it is practice, switch off the main lights in one building and have people find the exit and the meeting point using only the backup lighting and the lights they carry.

Afterward, talk about what was hard. Was a flashlight missing? Did a door stick? Was a path blocked? Fix those items and repeat the drill occasionally so new workers get the same practice.

Do not run drills in a way that puts anyone near moving equipment or animals that could be spooked. If a drill reveals a real hazard, stop and fix it first. Your local fire department may be willing to advise on exit planning for your buildings.

• Choose a calm, supervised time
• Practice exits and the meeting point
• Note and fix problems found
• Repeat so new workers are included
