Electrical Safety

Industrial Consumers
S.No.  DO'S   DON'TS 
1.Place men working sign boards
on all switches before commencing work

Don't close any switches unless you are familiar with the circuit which controls and know the reason for its being kept open.
2.Ensure that all the controlling switches are opened and locked or the fuse withdrawn before working on any circuit or apparatus.Don't touch or tamper with any electrical gear or conductor. Unless you have made sure it is Dead and Earthed. High voltage apparatus may give leakage shock or flash over even without touching
3.Treat circuit as alive until they are proved to be dead.Don't test a circuit with bare fingers or hand or other make shift devices to determine whether or not it is alive.
4.Turn away your face whenever an arc or a flash is expected.Don't close or open a switch or fuse slowly or hesitatingly. Do it quickly, positively and firmly.
5.Please see that all splices and connections are securely made.Don't use wires with poor and deteriorated insulation.
6.Discharge to earth thoroughly all cables before working on the cores.Don't be haste and careless. This cause many accidents.
7.Do test rubber gloves periodically.Don't throw water on live electric equipment in case of fire. It is dangerous.
8.Do place rubber mats in front of electrical switch boards.Don't use fire extinguishers on electrical equipment unless it is clearly marked as suitable for that purpose.
9.Make sure that all employees are familiar with the location and use of fire fighting apparatus.Don't work on a pole or elevated position when line is alive, without safety belt and rubber gloves and unless a competent person stands on the ground nearby to direct operations and give warning.
10.Make sure, when using fire hose, that the jet of water breaks into a fine contact with live electrical apparatus.
Don't use a ladder without a lashing rope otherwise the ladder should be held firmly by another person.
11.Check fire extinguishers periodically to ensure that they are all in good conditions.Don't go near running belts and machines.

Tips About Sitting

1.Most of us sit too much. The average person sits more than 8 hours per day.
Many office workers sit as much as 15 hours per day. Think about all the
sitting in your typical day; sit at breakfast, sit on your way to work, sit at
work, sit on your way home from work, sit for dinner, and then sit to watch TV
or surf the internet.

2.Sitting puts your metabolism to sleep. 60 to 90 minutes of inactivity (like
sitting) is enough to shut down the enzymes responsible for producing HDL- the
good cholesterol, and for regulating blood sugar. Chronic inactivity is
now thought to contribute to our diabetes epidemic.

3.Sitting is harder on your back than standing. Sitting tenses the hamstrings
and causes a flattening of normal curve in the low back. This distortion of the
spine increases the internal strain of the back. Sitting upright or sitting in a
forward bent position is particularly hard on the back. (see the Trunk and Back
Pain link above for more on this subject)

4.Sitting with an open hip angle of greater than 90° reduces back tension.
Sitting in a reclined posture, thighs-declined, or even slouched back against
the back cushion can reduce tension in the spine. This reduces the hamstring
tension and shifts some of the upper body weight onto the back cushion.

.Sitting provides more stability and control for detailed work as opposed to
many types of stand up work. Sitting is easier on the Musculo-skeletal system
(except as noted above in number 3).

6.An hour of daily exercise won't counteract the negative health effects of
sitting. Running, biking and other types of exercise are great for improving
fitness, but they don't counteract the negative health effects of prolonged
sitting. Exercisers who sit most of the day are known as active couch potatoes.

7.You need to stand and move each hour or more to maintain health. Sitting puts
your metabolism to sleep. Movement like standing, walking, and other leg-muscle
activity stimulates your metabolism and restarts your body.

8.Adjust your chair for comfort, support, and movement. You chair should fit you
and your physique, and it should allow for a variety of postures and movement.
Adjust the back rest cushion up/ down to fit the curve of your low back, adjust
the seat height for a comfortable leg support, and set the backrest to allow
supported relining and movement back and forth. While seated you should fidget,
squirm, contract/relax your muscles, and flex/extend your legs. Remember
movement is good, sitting still for long periods is bad.

9.Your best posture is your next posture. There is no single best ergonomic
posture. Most experts recommend a variety of positions and postures including
these four reference postures; upright supported, reclined seated, thighs
declined, standing.

10.Don't sit if you can stand, don't stand if you can walk. Thomas Jefferson
and Ben Franklin both knew that standing for work was a good thing. Both of
these great Americans had stand up workstations.

Dont Sit on Wallet

Your wallet can be real pain for your back and the buttocks, and it can even lead to shooting pains down the legs. Sitting on a wallet for prolonged hours every day can compress sciatic nerve which passes beneath piriformis muscle and leads to piriformis syndrome, low back pain & self-inflicted sciatica.  
The wallet acts as a wedge that forces the pelvis, spine and body out of alignment. Just as you would not sit on a brief case or a rock for an extended period of time, you should not sit on your wallet. Anyone who drives more than a half hour sitting on a wallet, is a candidate for sciatica or back pain.
The healthiest option is to move the wallet to your front pocket. If it’s must to keep your wallet in your back pocket, you should remove it before you sit down. 
You will immediately have a feeling of enhanced well-being, knowing that your pelvis is perched on a level surface and all the musculoskeletal structures above it are better off for your effort.
