Work Activities and Hazards Controls Clean windows, mirrors, and lights as needed. Do not use a hand-held cell phone or text while driving. Activate vehicle’s hazard flashing lights if driving slowly or temporarily stopping on roadways. Place vehicle in park (automatic) and set parking brake (manual), turn off vehicle, and lock vehicle when leaving vehicle. If parking to temporarily exit the vehicle, ensure vehicle is parked in a location that will not create a hazard for others.

Fueling Equipment Do not smoke, use cell phones, radios, or other battery powered equipment when fueling. Turn off ignition to equipment prior to fueling. Have ABC fire extinguisher and spill kit present when fueling. Report all spills immediately to supervisor.

Struck by mobile equipment / working near roadways

High visibility clothing or vest is required when working in or adjacent to roadways for extended periods (other than transient) or when in areas of mobile equipment operation.

Heat Stress Utilize engineering controls where feasible. Drink plenty of fluids throughout the day to stay hydrated. If signs or symptoms are present; stop work, notify supervisor, and find an air conditioned / cool location to rest in. During periods of excessive heat, ESH will communicate work/rest work cycles over the plant radio. Contact ESH Group to establish work regimens and / or physiological monitoring as needed.

Cold Stress Utilize engineering controls where feasible. Drink plenty of fluids throughout the day to stay hydrated. When working in temperatures <37° Fahrenheit (F), wear additional clothing such as gloves, head cover, and insulated clothing to insulate and protect the skin from direct exposure. If clothing gets excessively wet from sweat or otherwise, clothing should be changed as soon as practical. Heavy shivering, excessive fatigue, drowsiness, irritability and euphoria are indications of cold stress. If signs or symptoms are present; stop work, notify supervisor, and find an area to warm up in.

Work With (UV Light) Exposure

Use SPF 15 or greater sunscreen on exposed skin, as needed. Wear safety glasses with adequate UV protection.



Page 5 of 14

Hearing loss Wear ear plugs and/or ear muffs when near equipment that is subjectively loud. Hearing protection is

required when sound levels are ≥ 85 dBA. Contact ESH for determination as needed. Insects and animals Be observant for snakes, spiders, wasps, bees, etc. when working outdoors.

Utilize insect repellant when performing activities in forested or grassy areas during the Spring, Summer, and Fall when biting insects are of the greatest concern. Do not disturb live or dead animals or animal droppings. Contact O&M for removal or cleanup as necessary.

Poisonous plants Be observant for poison ivy, oak, and sumac when working outdoors and avoid contact. Contact with poison ivy/oak/sumac may cause contact dermatitis even when the plants appear dead or dormant. If contact is unavoidable, wear clothing (e.g. long sleeves, gloves, safety glasses, face shield, etc.) as required by the work activity to prevent skin contact. Barrier cream is designed to prevent the oils from poisonous plants from contacting the skin and should be used as needed. Avoid hand to face contact without removing gloves. If contact with poisonous plants is suspected to have occurred, employees should remove any clothing or PPE that may have come in contact and shower as soon as possible. Clothing or PPE that may have come in contact should be cleaned before reuse or disposed of.

Work in Other DOE Contractor Areas

Notify DOE contractor prior to entry and follow any DOE contractor specified requirements. This includes requirements for work control.

Nuclear Criticality The controls specified in this section apply to operating industrial equipment in the Limited Area unless operating industrial equipment exclusively in a location outside of any Initial Exclusion Zone as depicted on drawing C5E19766-A01 (attached) and with your supervisor’s approval.

Individuals operating industrial equipment in the Limited Area (LA) or supporting equipment operation (e.g. escort, RCT, maintenance, etc.) shall have received TSR Rev 3 Implementation Crew Briefing (F00560CB) When operating industrial equipment in the LA or supporting equipment operation (e.g. escort, RCT, maintenance, etc.), an Electronic Personal Dosimeter must be worn by each individual. When operating equipment that requires hearing protection, an EPD ear piece and ear muffs are required. EPDs may be obtained in C-300 as described in Crew Briefing F00560CB. EPDs shall be verified and tested prior to use as described in Crew Briefing F00560CB. If while in use the battery icon is visible in the lower left-hand corner of the display OR the symbol in the upper right-hand corner is not blinking; THEN immediately return to C-300 and obtain another EPD. IF the EPD alarms and other EPDs in the area do not alarm; THEN immediately return to C-300 and obtain another EPD. If the EPD alarms and there are no other EPDs in the area OR one or more other EPDs in the area

Attachment A – COVID-19 Control Plan What is COVID-19? Coronavirus is a family of viruses that have been known since the 1960s and includes the "common cold." This type of virus is typically found in animals and rarely can cross-contaminate with humans. Previous coronavirus outbreaks have included the Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The Coronavirus Disease (COVID-19) was first noted in mid-December 2019 in Wuhan, China. It has since spread world-wide, affecting nearly all countries. The virus is thought to spread mainly from person-to-person:

• Between people who are in close contact with one another, within the CDC social separation guidance (about 6 feet).

• Through respiratory droplets produced when an infected person coughs, sneezes, or talks. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs or be transferred from surfaces into mouths, eyes or noses by hand contact.

• Some recent studies have suggested that COVID-19 may be spread by people who are not showing symptoms.

What are COVID-19 symptoms? People with COVID-19 have had a wide range of symptoms reported – ranging from mild symptoms to severe illness.

These symptoms may appear 2-14 days after exposure to the virus: • Fever • Cough • Shortness of breath or difficulty breathing • Chills • Repeated shaking with chills • Muscle pain • Headache • Sore throat • New loss of taste or smell



Page 8 of 14

Are some people at greater risk for COVID-19? Based on what we know now, those at high-risk for severe illness from COVID-19 are:

• People 65 years and older • People who live in a nursing home or long-term care facility

People of all ages with underlying medical conditions, particularly if not well controlled, including:

• People with chronic lung disease or moderate to severe asthma • People who have serious heart conditions • People who are immunocompromised

o Many conditions can cause a person to be immunocompromised, including cancer treatment, smoking, bone marrow or organ transplantation, immune deficiencies, poorly controlled HIV or AIDS, and prolonged use of corticosteroids and other immune weakening medications

• People with severe obesity (body mass index [BMI] of 40 or higher) • People with diabetes • People with chronic kidney disease undergoing dialysis • People with liver disease

If you are concerned that you are at high risk for severe illness from COVID-19 and would like to discuss those concerns with our Occupational Medical Provider (OMP), you are encouraged to do so. What should you do if experiencing COVID-19 symptoms? If symptoms develop while at work,

1. Isolate yourself from others; 2. Notify your supervisor/project manager; and 3. Contact the OMP at 441-5766.

If symptoms develop while away from work; 1. Do not come to work; 2. Notify your supervisor/project manager; and 3. Contact the OMP at 441-5766.

Prevention 1. Stay home if you are experiencing symptoms of COVID-19.

On April 2, 2020, COVID-19 health screening was initiated at the C-104 Access Control Facility. During the screening personnel are asked a series of questions about recent activities and health status in accordance with CDC guidance and have their temperatures checked via forehead thermometer prior to entry into the workplace. Anyone coming on site must go through the screening. 2. Maintain social distancing

Limiting face-to-face contact with others is the best way to reduce the spread of COVOD-19. Maintain at least 6 feet from other people. Following are some ways to encourage social distancing.

• Staggering start times, breaks and lunch periods. • Avoid scheduling meetings that would compromise social distancing. • Teleconference meetings whenever possible.

3. Practice good personal hygiene

• Wash your hands often with soap and water for at least 20 seconds especially after you have contacted surfaces in common areas, or after blowing your nose, coughing, or sneezing. Research suggests hot water is not more effective than cold water at killing/removing viruses.

• If soap and water are not readily available, use a hand sanitizer that contains at least 60% alcohol. Cover all surfaces of your hands and rub them together until they feel dry. WARNING – Hand sanitizers contain alcohol and are flammable. Ensure sanitizers have fully evaporated and hands are dry before exposing them to any potential ignition source. Refer to the sanitizer use instructions and warnings for additional precautions.

• If not wearing a face covering, cover your nose and mouth with a tissue or your arm when you cough or sneeze.

• Avoid touching your eyes, nose, and mouth with unwashed hands.

4. Clean and disinfect surfaces

• Clean AND disinfect frequently contacted surfaces daily. This includes tables, doorknobs, light switches, countertops, handles, desks, phones, keyboards, toilets, faucets, and sinks.

• Facility Managers should establish cleaning schedules and items to be cleaned in each facility with clear assignment of responsibility.

• If surfaces are dirty, clean them with detergent or soap and water prior to disinfection.

• Follow the manufacturer’s direction for use of disinfectants, paying close attention to required minimum contact time.

• Wash your hands immediately after cleaning and sanitizing surfaces.

• Gloves will be available for cleaning and disinfecting, however washing your hands following cleaning and disinfecting is the primary control measure whether wearing gloves or not.

5. Wear a face covering

• When to wear

Face coverings are required at all times while on site (including during health screenings) with the following limited exceptions: • While eating or drinking; • While smoking or vaping in designated areas; • When prohibited by other regulations (e.g. where fire retardant clothing is required) • When respiratory protection is worn; and • As needed for temporary relief.

In all such exceptions, social distancing should continue to be maintained. The purpose of the face covering is not to protect the wearer from the virus but rather prevent the wearer from spreading the virus. Face coverings should not be used as a justification for compromising social distancing.

Page 11 of 14

• What to wear

If you would like to use a face covering you already have or purchase a personal face covering you are encouraged to do so. Otherwise, face coverings will be provided to each Organization and staged for convenient access. Face coverings must be

1. Inspected prior to use; 2. Cover your nose and mouth; 3. Fit snugly against the side of your face; 4. Be secured in place; and 5. Allow for breathing without restriction.

• How to maintain

o When feasible, wash or sanitize your hands prior to donning or doffing a face covering to minimize the risk of spreading the virus from hands to mouth/nose.

o Non-disposable face covering should be cleaned as recommended by the manufacturer.

o Disposable face coverings should be replaced after each shift. o Face coverings should be stored in a closed container such as a drawer or ziplock

bag and in a manner to prevent damage, distortion, and others coming into contact with it.

o Individuals should not wear or handle face coverings worn by other individuals. o When worn in a radiological contamination area, the face covering must be

surveyed out of the area at the boundary control station as you would any other personal item.

If you have a health-related concern regarding your ability to wear a face covering, contact the OMP. If you have a safety-related concern regarding use of a face covering, pause work immediately and notify your direct supervisor. The SST management team will determine if an exemption should be granted and any necessary compensatory measures required to resume work.
