JOBSITE PROTECTIVE MEASURES The Company has instituted the following protective measures at this jobsite.

FOLLOW REQUIRED SOCIAL DISTANCING REQUIREMENTS AT ALL TIMES Social distancing of at least six feet of separation must be maintained by every person on the jobsite at all times. All persons must avoid physical contact with others (no shaking hands). Where work trailers are used, only necessary persons should enter the trailers, and everyone should maintain social distancing. All in-person meetings will be limited. To the extent possible, meetings will be conducted by telephone. Weather permitting, in-person meetings limited to less than 10 people will be conducted outdoors with appropriate social distancing maintained at all times. Whenever possible, conduct bid walks/inspections via video, such as Skype. Everyone on site will be required to stagger breaks and lunches, to reduce the size of any group at any one time. Because masks must be worn by all persons at all times on the jobsite, we recommend that meals not be eaten on the jobsite.

SCREEN ALL WORKERS AT THE BEGINNING OF THEIR SHIFT FOR TEMPERATURE AND SYMPTOM CHECK Ask workers if they have a fever, cough, shortness of breath, fatigue, muscle aches, or new loss of taste or smell. Thermometers used shall be ‘no touch’ or ‘no contact’ to the greatest extent possible. If a ‘no touch’ or ‘no contact’ thermometer is not available, either every worker can be provided its own thermometer, or a site thermometer may be used provided that the thermometer must be properly sanitized between each use. Any worker with a temperature of 100.4°F or higher is considered to have a fever and must be sent home. Workers may not begin work on a jobsite until a daily temperature check and symptom check has been completed. WEAR ALL REQUIRED PERSONAL PROTECTIVE EQUIPMENT (PPE) AT ALL TIMES ON THE JOBSITE In addition to regular PPE for workers engaged in various tasks (fall protection, hard hats, hearing protection), employers will also provide for use by employees:

• Gloves: Gloves must be worn at all times by everyone on the jobsite. The type of glove worn should be appropriate to the task. If gloves are not typically required for the task, then any type of glove is acceptable, including latex gloves. Employees may not share gloves.

• Eye protection: Eye protection must be worn at all times by everyone on the jobsite. Employees may not share eye protection.

• Face masks must be worn at all times by everyone on the jobsite. The type of mask worn is governed by Washington Department of Health guidelines Link and by Washington Department of Labor and Industries safety rules. Employees may not share masks. In order to ensure strict compliance, we recommend that employees do not eat meals on the jobsite. NOTE: The CDC is currently not recommending that healthy people wear N95 respirators to prevent the spread of COVID-19. Employees should wear N95 respirators only if required by the work.

• You must make a thermometer available to any employee who needs one for their individual use to take their temperature before beginning work on the jobsite. Alternatively, a hands-free thermometer can be used on the jobsite. Daily temperature screening of all individuals is required. If appropriate PPE can’t be provided, the jobsite must be shut down. A worker who does not believe they are safe to work is allowed to remove themselves from the jobsite. SHARING TOOLS, RIDES, EQUIPMENT, FOOD AND BEVERAGES IS DISCOURAGED Workers should limit the use of co-workers’ tools and equipment. To the extent tools must be shared, the Company will provide alcohol-based wipes to clean tools before and after use. Objects handled by more than one worker must be cleaned when the items are transferred. Physically wiping the object so it is visibly clean (no obvious soiling, smearing, or streaks) is sufficient.
