Electrical Safety

Posted on January 17, 2017 by Toni Guerrero

On a daily basis, we all come into contact with electrical appliances, equipment, devices…and it’s helpful to have basic Electrical Safety Knowledge.  Here’s a mini lesson on what to do and what not to do in case of an electrical shock.

FIRST AND FOREMOST:

The most important thing to have in mind is NEVER TOUCH THE PERSON RECEIVING THE ELECTRICAL SHOCK!!!  This goes against all human nature, as our first instinct would be to try to grab the person to safety.  However, electricity requires a continuous flow and will always look for it’s way out.  For example, if you touch or step on something energized and receive an electric shock, the current will automatically follow the quickest path to the heart and look for an exit.  This means that the electrical  current generally exits the body thru one of the extremities…hands, feet, or head.  The point of exit will always receive the brunt of the electrical shock.  Therefore, if you try to grab the person being shocked, you can be sure you will receive more severe injuries than they will.

With that being said, what should you do in the case of an electric shock?

1. Call 911
2. Try to locate source of power and turn it off as quickly as possible.  Appliances, breakers, devices…
3. Do your best to separate the person from the source of electricity with a non-conductive object…a wooden broom handle, plastic or cardboard.
4. While waiting for EMS to arrive, try to determine whether the casualty is responsive without moving them.
5. Check for any electrical burns and treat accordingly.  NOTE:  electrical burns may vary depending on how long the body is in contact with electrical current, the strength of current, type of current, and the direction the current takes through the body.
6. If the casualty is not breathing, you may have to conduct CPR.

Always take the necessary precautions to work safely.  Wear PPE and never work alone.

 

UPS Systems: Why you need them

Posted on December 23, 2016 by Toni Guerrero

WHAT IS A UPS SYSTEM?

An Uninterruptible Power Supply, or more commonly known as a UPS System is essentially a battery back up in the case of a power outage.  A UPS System can be relatively small, to back up computers and electronic equipment, or they can be big enough to power an entire town, and everything in between.

BENEFITS:

The benefits of a UPS System are that there is a virtually seamless interruption of power, meaning if your building has a power surge or outage, you equipment load will switch to rechargeable batteries within the UPS System, giving you uninterrupted power.  This allows equipment, machinery, and personnel to continue working, even if the power goes out.

SCENARIO:

Imagine you have employees operating forklifts, heavy machinery, up on ladders and scaffolding… The power goes out.  Think of the potential injuries, damaged goods, trip hazards and heaven forbid, fatalities that could occur.  Simply because of a power outage.  The benefits of having a back up system are priceless.

Lighting Maintenance Contracts

Lighting maintenance is imperative in order to have a properly functioning facility.  Imagine employees working in a dark warehouse.  The potential trip hazards could incur grave consequences, including lawsuits.  However, having a routine maintenance contract ensures lighting systems are performing efficiently, all year round.

Transfer Switches

Posted on December 2, 2016 by Toni Guerrero

Many people are familiar with Transfer Switches for backup Generators.  A transfer switch is essentially a switch that switches between 2 loads.  The purpose of a transfer switch is to provide power in the event of a power outage or if a utility source fails.  There are Manual Transfer Switches where you would physically have to throw a switch in order to turn on the backup Generator.  Then there are Automatic Transfer Switches, which will automatically switch over to the backup Generator.

Within Automatic Transfer Switches there are Open Transition Switches and Closed Transition Switches.  The most common is Open Transition, also known as break-before-make Transfer Switch because it breaks contact with one load before making contact with the other load.  That would cause a momentary interruption of power before the load switches to the backup power source.  Closed Transition Switches are known as make-before-break Transfer Switches, meaning the backup power source switches on before breaking contact with the existing load.  This is most commonly used for critical loads such as Elevators or Hospital equipment.
