Our International has issued detailed Stagecraft Reopening Guidelines covering Principles and Practices, Testing, Screening and Monitoring, Criteria for a Safe Return to Work, Control of Exposures, Communication, Education and Training, etc.
Starting on page 20 are Venue and Craft Specific Guidelines:
"Here are outlined necessary actions specific to each of the stagecraft departments to prevent members from COVID-19 infection. Responsibility for implementing these actions depends on everyone including those outside the department following the COVID-19 prevention plan. Consider designating a department member to take the lead on assuring that the necessary actions to prevent COVID-19 are being taken."
