Map the event by time and area
Describe the separate activity zones, expected attendance pattern and any intervals when most visitors will use the facilities. Include workers and vendors who arrive before public opening. Discuss whether one restroom group is practical or whether the walking distances call for more than one location.
Protect access during the public session
Queuing, signage and barriers should leave accessible routes and toilet entrances unobstructed. A service vehicle should not depend on travelling through a dense public crowd. Ask the organiser and provider how access will work between sessions or at other agreed times.
Treat supplies as an active task
Assign an event contact to notice low supplies, damaged equipment or an access problem and report it. Agree who handles cleaning and replenishment; volunteer checks are not a substitute for the servicing arrangement. Add handwashing based on the actual event layout and intended use.
Check the reopening and collection plan
For multiple days, confirm the service opportunity before the next opening. Keep the equipment accessible after the final session, even if fencing or tents are removed earlier. Do not assume the public closing time also authorizes a collection vehicle to enter.
