A tented reception needs an equipment plan as well as a seating plan. Ask where the generator, heaters, cooking equipment and fuel will go, who approves their use and who operates them during the event. Resolve those details before a cold evening or rain shower prompts someone to move equipment beside the guests.
1. Identify who obtains the required approvals
Seattle Fire’s tent guidance illustrates how several permissions can apply to one event. It distinguishes tent and assembly permits, additional permissions for propane or open-flame cooking, and permits for heating powered by something other than electricity. It asks for a site plan, interior floor plan and documentation about the tent. [1]
Those are Seattle requirements, not a nationwide permit list. Ask your venue which authority reviews the proposed reception and which supplier or organizer submits each application. Write down the applicant’s name, deadline and inspection arrangements.
A rental invoice showing a tent and heater does not tell you which approvals have been obtained. Ask who will confirm that the delivered equipment and layout match the accepted plan. Include cooking and catering equipment in that discussion.
If the venue says a permit is unnecessary, ask which event details that answer covers. Changing the tent, adding sidewalls or introducing fuel-burning equipment should prompt the venue to check whether the advice still applies.
2. Put the generator location on the site plan
CPSC says portable generators belong outdoors, away from windows, doors, vents and other openings. Its warning prohibits indoor operation, including garages, basements and sheds. [2]
NIOSH recommends placing gasoline-powered engines outside and at least 20 feet from building openings. It also warns that carbon monoxide can accumulate rapidly in partially enclosed spaces, even when they appear well ventilated. [3]
Have the equipment supplier assess the actual site, exhaust direction, nearby buildings, air intakes and occupied spaces. A measurement from a building opening does not, by itself, approve a generator’s distance from a tent. Ask the venue and relevant authority to resolve the complete placement.
Do not move a generator under the reception tent because rain starts, or closer to an opening because an extension lead is short. Tell the supplier if its proposed location conflicts with photographs, parking or guest circulation so it can revise the plan before arrival.
Identify who can operate or relocate the equipment. Keep guests and helpers from treating it as another item of reception furniture.
3. Confirm the heater type and the sidewall arrangement
Seattle allows only electric heaters inside tents under its published tent guidance. Other heaters must remain outside, and propane heaters must be at least 10 feet from the tent and required exits. [1]
This is a local example of why “we will bring patio heaters” is too vague. Ask for the exact heater type, intended placement, fuel arrangement and instructions for the proposed tent. Have the supplier explain how heat will reach the occupied area within the approved arrangement.
Do not substitute a household heater or a portable camping appliance because the ordered equipment is unavailable. Ask the supplier what replacement can be approved for the site, and what happens if suitable heating cannot be provided.
Tell the venue whether sidewalls will be installed, rolled down or changed during the evening. Agree who can authorize that change and who rechecks the equipment plan. An open-sided afternoon layout should not silently become an enclosed evening room with the same assumptions.
If the approved arrangement cannot maintain a comfortable reception, use the agreed alternative space or schedule. Avoid leaving that decision to an attendant trying to satisfy guests who are cold.
4. Assign power connections, weather protection and refueling
CPSC’s portable-generator safety alert identifies electric shock, fire and burns alongside carbon-monoxide hazards. It calls for suitable outdoor extension cords with adequate ratings, precautions against moisture and shutting the generator off and letting it cool before refueling. It warns against powering building wiring through a wall outlet. [4]
Ask the power supplier to account for catering appliances, lighting, music, heating and any other planned equipment. Adding an electric heater on the day should go through the person responsible for the electrical setup.
Have that supplier handle the connection design, cord condition, routing and weather arrangements. Ask how guests will cross any necessary cable route without disturbing it. Do not appoint a relative to combine domestic extension leads until everything reaches.
Put the refueling responsibility and timing in the supplier’s plan. Ask what happens during a necessary shutdown and which functions have an appropriate backup. Keep spare fuel storage and access under the venue’s approved arrangements.
Discuss rain before the event. Weather protection must suit the equipment and must not create an enclosed exhaust hazard. A decorative screen or improvised cover is not a substitute for the supplier’s operating instructions.
5. Preserve exit routes and emergency lighting during setup
National Park Service guidance for events on National Capital Area parkland requires an emergency plan, exit information and equipment locations. It prohibits furnishings and decorations from obstructing exits or their access and calls for a way to stop music and audiovisual effects in an emergency. [5]
That manual applies to those park events. Use it as an example of the practical information to discuss, rather than copying its exit counts or measurements onto a different venue.
Ask the venue to check the final arrangement after tables, flowers, bars, photo booths and equipment are in place. Confirm that service stations and queues will not occupy the intended routes. Give the DJ or band a direct instruction about who can interrupt the music.
Ask which lights will remain available if normal power fails and who checks them before guests arrive. Include the route from the tent to the agreed assembly point, suitable access for guests who need assistance and access for responders.
Keep the lightning shelter plan separate from the assumption that the reception tent is shelter for every emergency. The venue should identify where guests go for each relevant situation.
6. Tell staff how to respond to possible carbon-monoxide exposure
CDC lists headache, dizziness, weakness, upset stomach, vomiting, chest pain and confusion among common carbon-monoxide poisoning symptoms. The gas has no color or odor. [6]
NIOSH advises getting to uncontaminated air and seeking medical help immediately when symptoms occur, calling 911 or the local emergency number and staying away until the area has been assessed as safe. [3]
If exposure is suspected, leave the affected area and get emergency help. Tell responders about the generator or other fuel-burning equipment. Do not delay leaving to find a detector reading, and do not re-enter to retrieve bags or investigate the source.
Ask the venue which monitoring and alarm arrangements apply to the approved setup, who responds to an alarm and who accounts for guests and staff. A monitor does not grant permission to use equipment in an unsuitable location.
Chapter 13 of Bridegenic puts names beside practical jobs. Assign the event lead, equipment operator, emergency caller and guest-assistance contacts before setup. Those people should know the site address and access instructions without asking the couple during the reception.
