Do Chicago food booths need handwashing?
The Chicago Department of Public Health reviews special-event food booths, mobile food and sampling applications, and booths need a Summer Festival Food Vendor Sanitation Certificate. We do not state its handwashing rules here. Ask the department directly what your booth must have, and give that to the provider.
That is the whole of what is sourced. The department's Food Protection Services handles the review, and the certificate is part of the process for summer festivals. The detailed requirements belong to the department, not to a rental page.
If you are an organizer rather than a vendor, find out how your event handles vendor sanitation. Some events require vendors to bring their own handwashing, and some provide shared stations. Decide which, and say so when you order.
How many handwashing stations does an event need?
No Chicago count of handwashing stations is stated here, because none was found for Park District or city events. Ask the permit office, then ask the provider what it recommends for your headcount and hours. Place stations at every toilet bank and every food area.
A practical rule of thumb is to put a station wherever people eat or leave a toilet. A single station for a whole festival forms a line, and a line makes people skip it. More stations, closer to the action, get used.
Think about the hours. A tank that works for a three-hour party runs low on a ten-hour festival day. Ask the provider about refills and say how long the event runs.
Where should handwashing stations go at a crowded event?
Put them next to every bank of toilets, at the exit so people wash on the way out, and beside food areas. Keep the approach level and uncrowded, leave room for a line that does not block other paths, and avoid placing stations where runoff pools.
Water on the ground is a nuisance in any season. On grass it turns to mud, and on a cold day it can ice over. Ask the provider where drainage goes and whether a station can sit on a mat or a firm surface.
At a big event along a closed street, as at the larger summer festivals, stations also need a spot that crews and emergency routes can pass. Check your layout with the permit office, and see street festival toilets for that setting.
What changes in cold weather?
Water can freeze in a handwash tank when temperatures drop. Chicago's January average is about 25 degrees Fahrenheit, with lake wind adding to the chill. We have no sourced local rule, so ask the provider what it offers for cold-weather events and what it recommends before you book.
A winter market, a late-season race or a cold-weather job site may still need handwashing. Ask the provider whether it can supply a station suited to low temperatures, or whether it advises an alternative for a given night.
The cold-weather portable toilets page covers the winter side of the toilets, and the questions overlap. Raise them early.
