TV CORD RISK
Power cords can become frayed or damaged from heavy use and age and should be
inspected regularly. Frequently, mishandling (such as pulling a plug from a socket by
jerking the cord rather than removing the plug carefully by hand) causes the most
significant damage to a cord over time, tearing the external protective sheathing or
detaching it from the plug head and exposing energized wires. Less obvious than damaged
and frayed cords is the threat posed by missing ground prongs, the rounded third prong on
electrical plugs. These ground prongs often break off from mishandling or are removed
intentionally to fit a plug into two-prong outlets. Ungrounded plugs – especially on kitchen
appliances like refrigerators and dishwashers – can pose a significant electrocution risk.

13.4 injuries per 10,000 employees # 122 fatal injuries # 32% of employees unable to
work because of injuries from electric parts were away for thirty-one days or
More.
Common Hazards to Avoid with Power Cords

Regulations Related to Damaged and Ungrounded Power Cords



The Code of Federal Regulations (CFR 1910.303) states that electrical insulation shall
be free from recognized hazards that cause death or serious physical harm to
employees
The Code of Federal Regulations (CFR 1910.334(a)(2)(ii)) requires damaged or
defective power equipment to be rem oved from service until repairs are made and tests
show the equipment is safe
Missing ground prongs are a violation of Occupational Safety and Health Administration
(OSHA) regulations and the National Electric Code. As required by CFR
1910.334(a)(3)(ii), attachment plugs and receptacles may not be connected or altered in
a manner which would prevent proper continuity of the grounding conductor
Examples of Frayed and Damaged Power Cords
At right is a power cord for a shop appliancefound on an inspection of a
Congressionalfacility. The cord has been sliced open, exposingthe energized wires. The
appliance was stillplugged in and still in use.
To the left is a power cord in use in a Congressional facility. The cord has had its protective
sheathing torn away from the plug head, exposing energized wires.
PCB Etching Area
Here we showing that there are some chemicals substance may be hazardous. They can
affect your health. They can enter your body by injection, inhalation or skin absorption.
They may be in the form of solids, liquids, gases, fumes or vapors.
Ferric chloride
Potential Acute Health Effects:
Very hazardous in case of skin contact (irritant), of eye contact (irritant), of ingestion, .
Hazardous in case of skin contact
(corrosive, permeator), of eye contact (corrosive). Slightly hazardous in case of inhalation
(lung sensitizer). Non-corrosive for
lungs. Liquid or spray mist may produce tissue damage particularly on mucous membranes
of eyes, mouth and respiratory
tract. Skin contact may produce burns. Inhalation of the spray mist may produce severe
irritation of respiratory tract,
characterized by coughing, choking, or shortness of breath. Severe over-exposure can
result in death. Inflammation of the
eye is characterized by redness, watering, and itching. Skin inflammation is characterized
by itching, scaling, reddening, or,
occasionally, blistering.
First Aid Measures
Eye Contact:
Check for and remove any contact lenses. In case of contact, immediately flush eyes with
plenty of water for at least 15
minutes. Cold water may be used. Get medical attention immediately.
Skin Contact:
In case of contact, immediately flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing
and shoes. Cover the irritated skin with an emollient. Cold water may be used.Wash
clothing before reuse. Thoroughly clean
shoes before reuse. Get medical attention immediately.
Serious Skin Contact:
Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial
cream. Seek immediate medical
attention.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is
difficult, give oxygen. Get medical
attention immediately.
Serious Inhalation:
Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a
collar, tie, belt or waistband. If
breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-tomouth resuscitation. Seek medical
attention.
Ingestion:
If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never
give anything by mouth to an
unconscious person. Loosen tight clothing such as a collar, tie, belt or waistband. Get
medical attention immediately.
