JOB AID: Misting Stations

Signs posted at misting stations.

This job aid provides specific implementation guidance for misting stations as a public health heat intervention, following the City of Portland Severe Heat Operational Guidelines, which Portland Bureau of Emergency Management (PBEM) updates annually.

Job Aid content was last updated in August 2022. PBEM turned misting station operations over to the Water Bureau for subsequent heatwaves, but this job aid is preserved in case NETs are deployed to them in the future.

Background

In June 2021, Portland experienced an unprecedented heatwave over several days, reaching 117 degrees Fahrenheit. Following this incident, PBEM worked with Portland Parks & Recreation (PP&R) to build and deploy several misting stations in canopy tents around underserved heat island areas in the city that were staffed by NET volunteers, and in 2022 began to loan out misting stations in canopy tents to community-based organizations (CBOs). In 2022, Portland Water Bureau (PWB) began offering stand-alone misting stations with a water bottle filling option at several locations. As of 2023, PBEM continues to loan out misting tents to CBOs that provide lifeline services at their locations, while Parks has taken over offering misting tents to City-sponsored special events, and PWB will deploy unstaffed misting stations with potable water bottle fill station during heatwaves as a life safety measure.

During heatwaves, misting station locations and hours will be shared on the Multnomah County Help for When it's Hot webpage and 211info's website. Misting stations uniquely serve people who may not want to visit indoor cooling center locations.

Concept of Operations

Locations

The following parks have been identified by PP&R and PWB that meet the following criteria:

• Serve underserved neighborhoods (according to FEMA Community Resilience Index)
• Are in heat islands
• Have a lower occurrence of other public water and cooling amenities (pools, splash pads)
• Have easily accessible potable water hook ups (hose bib).
• Other considerations:
  • Temporary closure of cooling amenities (i.e. splash pad offline for repair)
  • Free lunch and play parks

These sites could be evaluated annually based on reported usage and changes in PP&R water amenities. These sites are not prioritized. Selection of which sites to activate should be determined based on availability and locations of emergency cooling centers.

Storage

Year round, the misting station supplies are stored by PBEM at their leased space at the Jerome Sears maintenance building (2730 S.W. Multnomah Blvd). Access can be obtained from the PBEM Operations Manager. During a severe heat event, misting stations may need to be deployed for multiple days. To save time, they can be stored at several locations approved by Parks.

Placement

• Misting stations: Set up on grass, not dirt or bark chips, to avoid mud. Do not put on paved surfaces, to avoid creating a slip hazard.
• A-boards: Put wherever it seems people may notice them, with an A-board and sign. Examples: Bus stops, sports fields.

Supplies

The following supplies belong to PBEM and are stored at the Jerome Sears maintenance building.

1. (6) 10x10' Pop-up canopies.
2. (26) A-boards
3. (50) plastic folding chairs
4. (6) White buckets. These will be filled with water on site and tied with rope to the canopies as weights.
5. (6) 40' Black misting hoses. These have already been built with misting nozzles and are ready to go.
6. Tote 1:
   • (12) 25' white hoses. Zip tied in coils for year-round storage. This hose is similar to many garden hoses (pliable}. These will connect the water hook ups to the thicker black hoses.
7. Tote 2:
   • Black zip ties of varying size. Used to tie black misting hose to the canopy.
   • White nylon rope. Use to tie white hoses in coils for year-round storage.
   • Extra black misting hose, to be used to make more misting hoses. The plastic material is less pliable than the white hose, and can easily kink, which stops water flow. Kinks can be worked out by pressing with pliers.
8. Tote 3:
   • (7) Clear packaging tape. Use to tape signs to A-boards.
   • (6) Water keys - (2) 1-size & (4) 4-size. The 4-size is the most useful. Water keys open hose bibs.
   • (4) Pliers. These were used to build the misting hoses, but can be used to work out kinks in the black hose.
   • (3) Duct tape. May not need, though has been used to tie coils for year round storage or to secure hose connections.
   • (1) Scissors.
   • (4) Wire cutters. These were used to build the misting hoses.
   • Extra plastic connectors and end pieces.
   • Rubber-palmed gloves (to avoid pinch points during canopy setup).
   • Rite-in-theRain paper, pencils/ballpoint pens, clipboards for any note-taking.
   • Sign-in/out sheets for staff (e.g. NET Form 2a).

Staffing

A team of two PBEM staff will set up and take down stations daily, with the assistance of volunteers who are on shift. PBEM staff are necessary because they can drive PBEM vehicles, have access to Jerome Sears, and can be entrusted with Parks security codes and keys. PBEM staff are responsible for following this job aid (see Responsibilities below). Misting stations must be staffed by two people at all times to avoid loss and ensure safety.

Generally, PBEM will ask Neighborhood Emergency Team {NET) volunteers to staff them for four hours at a time. Volunteers should have a PBEM NET Coordinator to report to. Volunteers should report to the PBEM NET Coordinator if any unsafe activity is occurring on site. After the severe weather event is over, the PBEM NET Coordinator will send a survey to the volunteers to collect feedback on their deployment.

Procedure

Build the mister

Supplies needed to build one station

Get you one of these here. DIG 12" mister, 2 GPH mister end piece. Yesssssir. Fine piece of apparatus here.

• (1) 50 foot black rubber memory-flex irrigation hose.
• (16) DIG 12", 2 GPH mister end piece with memory-flex tubing (available from Home Depot: Model #7760F, see photo to right).
• (1) 25 PSI ¾" aerator hose nozzle attachment.
• (1) ½" black hose end cap.
• Drill with drill bits.

Directions

1. Cut black rubber hose to length of canopy interior plus one leg (40 feet +10 feet = 50 feet).
   • Do not need to add any on/off valves to the hose. Valves actually makes the hose more complicated to use because it's one more thing that needs to be checked when water isn't coming out of the hose.
2. Using the power drill, drill ≈16 small holes for nozzles into the black hose every ≈1.5 feet. Start with a small bit size and if the nozzle attachment still doesn't fit, make the hole slightly bigger. Be careful not to drill out the other side. Leave a "tail" at one end (no nozzle attachments inserted) to drop down to the ground, which will be the end that attaches to the hose connected to the bib.
3. Using the DIG 2 GPH Mister with Memory-Flex Tubing, insert the pointy non-nozzle end into the drill hole.
   • To ensure a tight seal, make the drill hole slightly smaller than the diameter of the mister. Then, use moderate force to put the non-nozzle end of the mister into the main hose. The hose will be slightly flexible and accommodate this, closing and sealing around the tapered end of the attachment.
4. Add aerator attachment to the hose's long "tail" that hangs to the ground, where it will be connected to the white hose that connects to the hose bub. Add the end cap to the end of the hose, which will be the end of the hose.

Assemble the station

1. Choose station placement.
   • Refer to station maps for hose bib locations.
   • Stations can be maximum 50 feet from a hose bib.
   • Set up stations on grass, not dirt or bark chips, to avoid mud. Do not put on paved surfaces, to avoid creating a slip hazard.
2. Set up canopy.
   • Takes at least two people, preferably four. If volunteers are on site, ask for their assistance.
   • Depending on the canopy type, you may need to push up the middle as well as pull the legs away from each other.
   • Don't rush. Be careful of pinching fingers.
3. Attach black misting hose to canopy.
   • Start with the aerator end, pointing down and near the ground. This will make it easier to connect to the white hose.
   • Zip tie the black misting hose to the canopy. Be careful to avoid kinks by going slowly, unwinding the coil, and using pliers if needed to press kinks out.
4. Connect misting hose to hose bib with white hose.
   • Open hose bib with water key.
   • Screw white hose onto hose bib.
   • Screw white hose into black misting hose.
   • Turn on water with water key.
5. Set up A-boards with directional signage at main park entrance or busiest access point as needed.

2. Assess whether any supplies should be replenished - use supply list as guide
3. Store materials together in a storage room (not in a front bay).
4. Tie all hose coils neatly.
5. Close all storage boxes and stack together.
6. Working with PBEM Operations, purchase additional material.

Misting Station Lead:

Jeff Perkins [phone number]

Unit Overview: The Community Services Branch, in alignment with Emergency Support Function ESF #6, is responsible for coordinating staff at mass care and sheltering operations during an emergency hot weather response.

Position Responsibilities: The general staff position performs a variety of roles necessary to run a misting station established by the City of Portland, or its partners. This position is supervised by a remote PBEM staff member (the Misting Station Lead). All Misting Station Volunteers are asked to:

• Welcome visitors;
• Monitor the equipment and report problems to the Misting Station Lead;
• Call 9-1-1 if anyone appears to have heat stroke or another serious medical problem, or if another emergency arises. When you have time, after you call 9-1-1, inform the Misting Station Lead;
• Provide public information about other open cooling centers and how to get there;
• Keep a tally of how many people visit the site.

Some shifts will also be asked to help with set-up and tear-down. Staff might be rotated through roles during each of their shifts.

Working Environment:

• Misting Stations will be outdoors in public parks, usually located in shade. County employees in this role need to take the Workday Excessive Heat training since they will be outdoors.  Some may have already taken it, but if not, it should be completed prior to shift.
• Assignment may include bending, walking, standing for extended periods, and carrying less than 20 pounds (hose, spraying equipment, shade canopy, etc.)
• Volunteers should practice physical distancing (maintaining six feet of separation from others) among both guests and staff.
• PBEM will make every attempt to ensure misting stations are staffed sufficiently to appropriately handle facility capacity. If you feel that staffing levels are not appropriate to maintain operations notify the Misting Station Lead immediately. The misting station should not be left unattended if possible to discourage damage or theft.
• Pets may be present (potential allergens, fleas).
• Guests at misting stations will not have undergone a “Wellness Check” or symptom screening. Guests should follow appropriate precautions consistent with public health recommendations for all people during the COVID-19 pandemic.
• Guests might have chronic illnesses and/or injuries.
• Some guests may be experiencing ongoing mental health or substance use challenges. This may be a cause of distress for them. Please read the SAFETY MESSAGE below for guidance in this topic.
• Street noise and the noise caused by outdoor park maintenance equipment is something to consider when speaking with guests. Be aware that loud discussion can escalate situations because of the need to talk over the sound. Staff can also carry a notebook, in case written communication is needed with other staff and guests.
• Meals, snacks, and beverages will not be provided at the site. Bottled water will be available, but we encourage volunteers to bring their own in case of a shortage.

On-site Conduct

• Be patient, kind, and a good listener.
• Practice compassion, acceptance, and mutual respect.
• Create welcoming spaces.
• Ensure the identity of the individual has no effect on the services we provide.
• Use supportive, person-first language and non-threatening body language. Please be mindful of how your behavior can escalate or de-escalate any situation. Individuals visiting the site should be referred to as Guests.
• Weapons of any kind are prohibited in Portland Parks.
• Remember you have a team supporting you. Reach out to the Misting Station Lead if you run into any problems.

Qualifications

Required:

• Capacity to arrange safe travel to and from the site.
• Review of PBEM Misting Site set up and take down guide (included as a job aid).

Helpful (not required) skills/experience/qualifications include:

• Background working with individuals who are unhoused, in crisis, living with mental health and/or substance use challenges.
• Training in Mental Health First Aid, de-escalation, conflict management, mediation, and basic first aid.

Equipment & Supplies Needed

• Personal protective equipment:
  • Weather appropriate clothing
  • NET vest and ID (if you are a NET volunteer)

• A cellular phone for communication with co-workers or 911 during the shift. Phone numbers should be exchanged at the beginning of the shift.
• Snacks and water.

Safety

This section draws from the event Safety Plan (ICS 208).

1. Your personal safety is your first concern. If you feel threatened at any time, you should leave the site immediately even if that means abandoning the equipment. Once at a safe place, call the Misting Station Lead right away and inform them of the situation.
2. Never physically confront or touch a guest, as this can lead to conflict. NEVER attempt to restrain or physically engage with a guest.
3. Never touch a guest’s possessions without their permission.  This can also lead to conflict.
4. Volunteers should bring concerns about an individual’s health or an injury to the Misting Station Lead. If it is an emergency, call 9-1-1.
   • If any emergency occurs, contact 9-1-1 as appropriate, and notify the Misting Station Lead afterwards, when you have time.
   • Guide responders to the patient when they arrive.
   • Document your observations and role related to the incident.
5. PBEM encourages volunteers to review the OR-OSHA Heat Stress Prevention Video before their shift (2 minutes): https://osha.oregon.gov/media/videos-online/Pages/heat-stress-prevention.aspx. The coordinating agency will provide misting site staff with accommodation in alignment with the OSHA requirements.
6. To limit the spread of COVID-19, volunteers are encouraged to wear masks when not in the stream of the mist.

General Staff Duties

1. Do not leave equipment unattended unless an emergency prompts you to leave the site.
2. Arrive on time and stay for the duration of your shift, unless released early at the discretion of the Misting Station Lead.
3. Familiarize yourself with the facility. This will help you provide directions to guests.
4. Maintain situational awareness. Notify the Misting Station Lead of any guest or volunteer concerns as soon as they are discovered, and/or any concerns about equipment.
5. Assist in set-up and tear-down if needed, following the documentation provided.

Special Instructions

• Talk to someone regarding any response related stress. The following are tips to limit stress:
  • Take steps to promote your own physical and emotional healing by healthy eating, rest, exercise, and relaxation.
  • Talk with someone about your feelings - anger, sorrow, and other emotions - even though it may be difficult.
  • Call the Multnomah County Mental Health Call Center if needed: 503-988-4888
  • Do not offer to help guests outside of the site setting (personal gifts, rides in your car, stays on your couch, etc.)
• Data Collection: We would like to learn as much as we can about how frequently people use misting sites, and who uses them. Therefore, we ask volunteers do:
  • Keep a number count of all the people who use the misting site using the form provided.  If you can’t find a form, count the number of visitors every hour and report that.
  • After your shift, put the form back in the plastic “guest count” box.  If you could not find the form or box, email your observations to net@portlandoregon.gov.
