Exposure to Arsenic at Work
In The United States, workers have been exposed to arsenic while:
Torch-cutting scrap metal
Sawing treated lumber
Working in a battery manufacturing plant
Working at a hazardous waste site

Arsenic Exposure
You may be or are exposed to arsenic at this jobsite in the following activities or locations:
Arsenic is a byproduct of combustion of coal and is present in trace amounts in flyash and as scale on boiler tubes. Persons performing work in the Plant that may come in contact with large amounts of flyash such as working inside boilers and precipitators must be trained in Inorganic Arsenic Safety and follow Duke Power safe work processes for working around this product.

Health Hazards of Arsenic
Arsenic Exposure Limits
OSHA has set a level in the air that can’t legally be exceeded.
OSHA Legal Limit: 10 micrograms per cubic meter – like a drop of red dye in 55-gallon drum of water.
If the level in the air is above 5 micrograms per meter, certain protective steps must be taken.

Arsenic Exposure
How can arsenic get in your body?
Inhaling arsenic fumes while torch-cutting metal,
Swallowing arsenic dust on your hands while eating, drinking or smoking.
Inhaling dust from sawing arsenic-treated lumber, or dust from contaminated soil,

Arsenic effects on skin
Dust containing arsenic can cause skin irritation and other skin problems.
The form of arsenic known as arsenic trichloride is easily absorbed through the skin.
Protective gloves and clothing must be worn when handling products containing arsenic or if arsenic dust can get on your skin.

Controls
We have put the following controls in place to reduce the amount of arsenic you are exposed to:
Employees working in this area will be required to wear a respirator, Tyvec garments, goggles, etc depending on the type of work they are performing. BARRIER TAPE MUST BE USED AND PROPER SIGNAGE.EMPLOYEES MUST USE HEPA-VACS TO VACUUM OFF TYVEK COVERALLS PRIOR TO REMOVING AND DISPOSING OF THEM AND FOR CLEAN UP OF ASH DEBRIS.
NO BLOWING OFF OF COVERALLS WITH AIR HOSES.
NO EMPLOYEE WILL WEAR TYVEK OUTSIDE THE WORK ZONE NO EMPLOYEE WILL WEAR TYVEK OUTSIDE THE WORK ZONE FOR ANY REASONFOR ANY REASON

Warning Signs and LabelsWarning signs are posted at the entrance to any area where the levels of arsenic exceed the OSHA permissible limits.
These areas are called “exposure control areas”. No one can enter them without a respirator or protective clothing.
All containers containing arsenic also must have a warning label.

Respirators
Type of Respirators for Arsenic
In some jobs involving arsenic, you may need a respirator.
The type of respirator worn depends on the amount of arsenic in the air.
We will provide you with the proper respirator:
17
![Page 20: Arsenic Health Hazards](https://reader036.fdocuments.in/reader036/viewer/2022062404/55498302b4c90554648b4be5/html5/thumbnails/20.jpg)
Respirators You Must Use
1. Full Face air purifying respirator for all work involving scaffold removal from the boiler.
2. ½ face air purifying respirator for all work involving the removal flyash or the wash down of components containing flyash.
3. ½ respirator is required anywhere large amounts flyash are suspected.

![Page 21: Arsenic Health Hazards](https://reader036.fdocuments.in/reader036/viewer/2022062404/55498302b4c90554648b4be5/html5/thumbnails/21.jpg)
Respirators
Using Respirators
Respirators must be worn at all times when the amount of arsenic in the air is above the legal limit.
You must have a medical evaluation before you wear a respirator.
Respirators must fit properly to prevent leaks.
19
![Page 22: Arsenic Health Hazards](https://reader036.fdocuments.in/reader036/viewer/2022062404/55498302b4c90554648b4be5/html5/thumbnails/22.jpg)
Respirators
Respirators Must Fit Properly
You must pass a respirator fit-test before you wear a respirator to protect yourself from inhaling arsenic.
You can’t have a beard when you wear a tight-fitting respirator.
We will train you on how to use your respirator.

Medical MonitoringWhat medical monitoring is needed?
Anyone who is exposed to arsenic above the “action level” 30 days or more per year must be offered a medical exam.
The medical exam includes a chest x-ray and nasal and skin examination.
We offer you a medical exam at least once a year.
21
![Page 24: Arsenic Health Hazards](https://reader036.fdocuments.in/reader036/viewer/2022062404/55498302b4c90554648b4be5/html5/thumbnails/24.jpg)
More on Medical Exams
We will provide additional medical exams if you develop any signs or symptom associated with arsenic.
We will provide the doctor information on your arsenic exposure and respirator.
We will get the doctor’s written opinion on the results of the exam and any further steps recommended to protect you.
You will get a copy of the doctor’s report.
