UV exposure for officials, volunteers and touchline adults

Why non-playing roles can carry the longer day

A fixture has more exposed people than the team sheet suggests. Referees, umpires, line judges, race marshals, stewards, scorers, volunteers and parents may be outdoors before participants arrive and remain after they leave. Their exposure is often built from time rather than exertion. A player may rotate, be substituted, spend time indoors or under cover, and change clothing around the event. Someone operating a gate, touchline, checkpoint or finish area may have none of those changes.

Static work matters because the body is repeatedly presented to the same direction of light. A marshal facing an approach route may expose the face, neck, forearms and lower legs for a long period. A touchline adult watching play can stand with one shoulder, ear and side of the face more consistently exposed than the other. An official moving around a pitch has a different pattern, but may still be present for every minute of several matches.

Long tournaments make this easy to overlook. The mental model is often one match or one race. The operational reality is arrival, set-up, briefing, duty, gaps between sessions, pack-down and departure. Gaps are not automatically protected time when the person remains beside a pitch or course. The relevant unit is the whole event day.

This is distinct from the exposure questions faced by an athlete. It is not about performance or a particular sport's kit. It is about the less visible role at the edge of play, where attendance may be continuous and personal preparation may be left to chance.

Map an event day by hour, place and posture

Use a simple event-day map before the fixture. Start with the schedule, not an assumed session length. Make one row for each hour, or each meaningful change in duty. Record where the person will be, whether they are moving or stationary, which direction they usually face, and whether cover is genuinely available. Include the arrival and departure tasks that are often missed.

The map is not a prediction of a person's exact UV dose. It is a planning tool for identifying repeated, uncovered periods and body regions that may be missed. The Exposure Map method gives the broader approach: score exposure through posture, kit and session length, and state the derivation rather than treating a sport as one uniform condition.

For a tournament, create separate maps for the referee team, score table, gate, refreshments, car park and spectator edge. Those roles can have sharply different timing even at the same venue.

Use a practical decision rule before assigning positions

The following rule is intended for organisers, club volunteers and families deciding how to set up a fixture. It does not calculate a medical threshold. It identifies when a role needs a deliberate exposure plan rather than a general reminder.

A person need not meet every condition for the role to need planning. One fixed, unshaded station can be enough to change the day. Conversely, a long day can be moderated by genuine rotation between covered and uncovered work. The question is not whether shade exists somewhere at the venue. The question is whether the assigned person can use it without leaving an essential task uncovered.

This decision rule also helps avoid treating all spectators alike. A parent who comes for one short fixture is not in the same situation as a volunteer managing a tournament from opening to close.

What shade can and cannot change at a fixture

Shade can reduce direct exposure where it is continuous and usable, but a tree at the far side of a ground is not operational shade for an umpire who must remain near play. The same applies to a covered pavilion that is inaccessible during a marshal's duty. Shade needs to be located where the role is performed, or paired with a relief arrangement that makes a covered pause possible.

When choosing a position, inspect the pattern rather than only the presence of a structure. A shelter can cast shade at one time and leave the working area exposed later. A small canopy may cover a table but not the steward beside it. People also receive light from the open surroundings while under partial cover, so shade should be treated as one layer in a plan, not as permission to disregard clothing or time.

For static roles, practical options include moving registration, scoring or welfare points to a covered side of the venue where the task still works; locating a marshal at a position with natural cover where route safety allows; and scheduling handovers so a person can leave an exposed station. These are event-design choices, not individual willpower.

Do not make a shade plan depend on a person improvising on the day. If cover is not available at a necessary station, record that plainly on the event map and use rotation, clothing and timing to reduce the uninterrupted period. A delayed start, extra-time format or congested schedule should prompt a review of the rota rather than an assumption that the original plan still fits.

Clothing, hats and eyewear: useful limits for standing roles

Covering clothing can reduce how much skin is directly exposed, especially for people whose role allows sleeves, a collar and longer leg coverage. The practical issue is compatibility with the task. A line judge needs clear movement and sight; a steward may need visible identification; a race marshal may need to manage changing weather. Choose the most covering arrangement that remains suitable for the role, expected conditions and any safety requirement.

A hat can add protection for areas it covers, but its value depends on the brim, fit, wind and the role's movement. A cap leaves some areas less covered than a wider brimmed design. No hat creates coverage for arms or lower legs, and a hat that repeatedly has to be removed or held in place is unlikely to work through a whole shift. Officials should also consider whether headwear conflicts with required equipment or communication systems.

Eyewear may make prolonged visual work more comfortable in bright conditions and can reduce glare, but it does not cover the rest of the face and cannot substitute for shade or clothing. It must allow the wearer to see play, participants, vehicles, route hazards and signals clearly. Dark lenses are not automatically appropriate in every light condition or for every duty.

These measures have limits because bodies move, clothing shifts and jobs change. Treat kit as a layer within the map: note what is covered in each role, then identify what remains exposed. For a more general discussion of head and eye equipment in sport, consult the site's helmets, caps and scalp and eyewear in sport pages.

Brief the people beyond the team

Clubs and organisers can make this routine by placing exposure planning in the same pre-event process as stations, timings and welfare. The briefing should name non-playing roles specifically. A vague instruction aimed at “everyone” can leave volunteers and parents assuming it applies mainly to athletes.

A useful short briefing has five parts: identify which duties are outdoors for the full event; point out stations with no reliable cover; state the rota and who authorises relief; tell people what clothing and headwear are compatible with the role; and explain what to do if the schedule runs long. The coordinator should know who is covering a position during a break. Without that detail, breaks tend to disappear when the event becomes busy.

Before duty starts: where will you stand, for how long, what cover can you actually use, and who takes over when you leave?

Parents on the touchline need information early enough to act on it. Include the expected event window, whether the ground has usable cover, and a reminder that waiting before and after a match forms part of attendance. This is particularly important at festivals, finals days and multi-match fixtures, where a nominally short match can become a long day at the venue.

The clubs, coaches and duty of care page considers organisational responsibilities more broadly. This page focuses on the practical event design question: whether people who are not playing have a workable way to cover up, take a break and remain able to do their job.

Apply the map to common fixture settings

At field sports fixtures, the touchline may be the longest static position. Parents often move little once play begins, while substitute areas, officials and support staff can remain present across several games. The field sports and fixtures page addresses the sport context; add a non-player layer by mapping the sideline, technical area, gate and car park separately.

Golf events can extend beyond the period a single player is striking the ball. A starter, scorer, volunteer or accompanying adult may be outdoors across multiple groups, with long intervals in open positions. The golf, the long-duration case page is relevant because duration changes the planning problem. A person may assume that pauses are recovery time even when they occur in the same exposed location.

Race days introduce dispersed positions. A marshal placed at a junction may have no reason to move until the course is clear. Checkpoints, finish funnels and baggage areas can likewise become all-day stations. The map should include access: a covered place that requires leaving a safety-critical point is not available cover.

Timing also changes from one fixture to another. The UV index and session timing page can help frame why a midday block may deserve different planning from an early or late duty. It does not replace an event map, since a lower-index hour repeated over a long shift can still be material to the total time outside.

Limits of this guide

This guide concerns outdoor land-based fixtures and the people around them. It does not cover swimming, water-based events, immersion or claims about what water-resistance testing means. It does not assess an individual's skin, give medical advice, diagnose a reaction, or set a personal safe duration outdoors.

It also cannot decide whether a particular venue has adequate cover without a site visit and an understanding of the event. Wind, clouds, ground layout, duty rules, visibility requirements and emergency access can all alter what is workable. A map is therefore an operational record to revisit when the schedule, course or location changes.

For organisers, the central limitation is that planning cannot be delegated entirely to an individual. A reminder to bring suitable clothing is useful, but it does not solve an unstaffed station or a rota with no release point. Build the controls into the event design, then tell every non-playing attendee how they apply.
