Event contingency planning for small B2B events

01 Equipment and systems

Technology and equipment failure

Walk the actual event setup and list the equipment and services that a session depends on. Mark who tests each item, when it is tested, and what the team will do if it fails.

• Inventory projectors, microphones, Wi-Fi and network access, conferencing tools, event apps, power, adapters, and the devices needed to present.
• Pair each critical item with a tested backup or offline option: spare cables or batteries, a second microphone, a permitted hotspot, phone dial-in, a local copy of slides, a printed run sheet, or a paper check-in list.
• Decide how the session changes if internet access, power, the event app, or the conferencing platform is unavailable. Keep a current contact list and schedule where the team can reach them offline.

Planning prompt: Which failure would stop the next 15 minutes of your program, and what can the team use immediately instead?

02 Attendee updates

Communication breakdown

Choose one person to approve attendee updates and one person who can send them if the approver is unavailable. Keep a current, permission-aware contact list and draft short messages for a delay, room change, virtual switch, postponement, or cancellation.

• Choose at least two channels, such as email plus SMS, or an event app plus venue signage. Keep the same factual update across them.
• Use SMS for short, urgent instructions to the people affected, but never make SMS the only place important information appears.
• Every message should state what changed, what attendees should do, and a specific next-update time. For example: “The room is changing. Follow signs to Room B. We will update you by 10:30 a.m. local time.”

Planning prompt: If the main event app is down, who approves the notice, who sends it, and how will a person without SMS receive the same information?

03 Supplier agreements

Vendor performance or absence

List essential vendors such as the venue, audiovisual crew, caterer, speaker transport, captioning or interpretation provider, internet provider, and security team. For each one, name a main and backup contact and confirm the deliverable, arrival time, and escalation route in writing.

• Ask each essential vendor for written confirmation of its insurance coverage. Record who holds the contract: your organization, the planner, or another party—and who is responsible for payment and decisions.
• Write down what happens after late arrival, missed delivery, or work that does not meet the agreed scope: notice window, correction, substitute, credit, or other remedy. Ask for fees, markups, and commissions to be disclosed clearly.
• Review force-majeure language for severe weather, disasters, government or venue restrictions, public-health emergencies, and other events outside the parties’ control. Confirm notice steps and what happens to deposits, refunds, cancellation, postponement, and rescheduling.

Planning prompt: If this vendor cannot perform, who can authorize the backup, what does the written agreement allow, and who tells attendees? Have a qualified adviser review contract language for your jurisdiction.

04 Hybrid participation

Hybrid and remote accessibility

Ask participants about access needs early enough to arrange support. Confirm the chosen meeting platform and event materials work with the operating systems, browsers, devices, and assistive technologies your attendees use. The W3C event checklist recommends asking attendees about access needs, offering multiple ways to connect, coordinating captioners and interpreters, and sharing accessible materials directly. W3C guidance for accessible events.

• Use WCAG Level AA as a planning and review target for your event website and online materials. Ask platform vendors what accessibility information they can provide, then test key tasks with the assistive technology and operating systems your participants use. This is a planning target, not a statement that one event platform or every event is legally required to conform.
• Offer phone dial-in where it serves your audience. Confirm interoperability with the conferencing platform, captioning, and any telephone or SIP bridge you rely on; test the full path before event day.
• Arrange high-quality real-time captions in more than one language when your audience needs them, and arrange interpretation where applicable. Test that remote and in-room participants can see captions and that the interpreter remains visible, well lit, and easy to position or enlarge.
• Send accessible materials directly to participants before the session; do not rely on screen sharing alone. Check virtual whiteboards, polls, and other collaboration tools, and provide an accessible alternative for anyone who cannot use one.
• Plan for equal remote participation: repeat in-room questions into the microphone, monitor remote chat, and give remote attendees a clear way to speak. Test the room equipment and remote connection together, with a backup device, connection, or venue plan.

05 Well-being and staffing

Health, safety, and staffing disruption

Agree on a stay-home-if-sick message and flexible refund or rescheduling terms before registration opens. Name a local public-health contact and a medical-response lead; identify an isolation space, masks, cleaning and infection-control supplies, and the venue’s emergency-care process. Follow current local guidance and venue rules rather than treating this checklist as a current mandate.

• If someone becomes ill, move them away from others to the planned space, offer a mask in line with current guidance, and arrange emergency care when needed. Plan individual transport rather than shared transport.
• Decide who contacts local health officials for current advice and who communicates a possible exposure to affected staff or attendees while protecting personal information. Plan how the venue will be cleaned afterward; CDC’s current facility guidance distinguishes routine cleaning from situations that call for disinfection. CDC facility cleaning guidance and its archived event-planning resource are references to review alongside local advice.
• List backup people for illness or caregiving absences, including who can take over registration, speaker support, accessibility coordination, vendor calls, and incident communications.

Before postponing, cancelling, or reducing attendance, weigh crowd size, vulnerable attendees, close-contact risks, current local conditions and conditions where attendees are travelling from, and available local health capacity. Check current advice and your contracts before communicating a decision. CDC advises organizations to support people staying home when sick and to consider flexible cancellation or refund policies. CDC guidance for people and organizations when someone is sick.

06 Place and access

Weather, venue unavailability, or restricted access

Choose a decision owner and a decision time for weather and venue changes. Identify a backup indoor venue or a virtual option, and test the steps needed to move the event before you need them.

• Get cancellation and postponement terms, refund and rescheduling outcomes, notice deadlines, and any force-majeure process from the venue in writing.
• Map attendee arrival routes, accessible entrances, vendor load-in, traffic disruptions, and who will contact the venue if one route closes.
• Plan for a building lockdown or other access restriction: who can authorize a move, which backup room or virtual link is ready, how speakers and vendors switch, and which two attendee channels carry the update.

Planning prompt: What is your latest safe decision point for moving indoors, changing venues, switching online, postponing, or cancelling—and what does each choice mean for attendees and their money?

07 People and venue operations

Security and crowd management

Walk through arrival, registration, room movement, and exit with the venue. CISA’s mass-gathering planning tool covers event-specific security planning, entry controls, vehicle traffic, emergency plans, crowd management, and physical security; use it to build a site-specific discussion with your venue. CISA Mass Gathering Security Planning Tool.

• Decide how badges are issued, checked, replaced, and collected; who responds to theft, a lost badge, or unauthorized entry; and when to involve venue security.
• Map crowd flow at doors, queues, food areas, and exits. Keep emergency exits clear and identify a first-aid location that staff can point out quickly.
• Name one on-site incident commander and a backup. Brief staff on who calls emergency services, who meets responders, who manages the room, and who sends attendee updates.
• For a medical emergency in a crowded room, pause the program, make a clear path for responders, and follow the venue’s emergency plan. Record the decision and communication roles before doors open.
