Corona Virus and Negative Pressure rooms

At Cirrus Outdoors LLC, the safety and well-being of our employees and our customers is always our priority, and we recognize the important role we play in providing our Tactical and HVAC Business customers with product during this critical time. We are actively monitoring the COVID-19/Coronavirus situation and taking steps to help keep our communities safe. We wanted to share with you some steps we are taking. See video below…

Aligning with public health authorities

We have a team dedicated to our response to this pandemic and have Business Continuity Plans to ensure the continuation of services. We are closely monitoring updates from the Centers for Disease Control and the World Health Organization regarding COVID-19. We will continue to seek guidance from these agencies, public health officials and government agencies on an ongoing basis.

Protecting our employees and customers

As our employees interact with customers and the general public, we have taken steps to limit exposure to the virus. We have put restrictions on travel, postponed large-scale events, limited the size of meetings, provided remote-work solutions, and continue to reinforce safe behavior in every environment – We are partnering with manufacturing to source the Cirrus Wind Indicator and cartridges as fast as possible and are prioritizing distribution to our customer-facing locations. We have committed thousands of Wind Indicators to the distribution of Health Care Facilities and Quarantine and HAZMAT operations.

You have our commitment to delivering a safe and reliable product to help curb the spread of the Virus in health care facilities around the World.

May God Bless You, World Leaders, Government Officials, Public Health Officials, Hospital Facilities and Staff, First Responder’s, LE and may the World find peace and healing during these difficult times.

What is a NEGATIVE PRESSURE ROOM? https://en.wikipedia.org/wiki/Negative_room_pressure

How to Test using a Cirrus Wind Indicator…

Step 1

Close all the windows and doors in the room.

Step 2

Replicate the conditions under which you intend to test for negative pressure. For example, turn on the air conditioner, fans or other air-movement devices.

Step 3

Exit the room and close the door behind you.

Step 4

Inspect the bottom of the door. If there is a crack under the door, such as found in interior doorways, use the crack as the negative pressure test point. If the doorway is full sealed, open the door to create an opening approximately one-eighth inch wide.

Step 5

Hold the Cirrus Wind Indicator near the crack. Depress the Cirrus Bellows to expel smoke. If the smoke is drawn into the room, the room has negative pressure. If the smoke is pushed away from the room, the room has positive pressure. If the smoke remains suspended in the air, the air in the room is at the same pressure as the air outside the crack.
