Temporary Parking Areas AHA (Activity Hazard Analysis / Job Hazard Analysis)
Updated 2026-06-23
A Temporary Parking Areas AHA (Activity Hazard Analysis / Job Hazard Analysis) is the plan that keeps people safe at the pedestrian-vehicle interface, on the parking surface and grade, and in the parking lighting and layout. Temporary parking areas establish the temporary parking for the site workforce and visitors — combining the pedestrian-vehicle-interface and struck-by hazard, the surface-and-grade and stability hazard, and the lighting-and-layout hazard. This guide walks through building a Temporary Parking Areas AHA that names the pedestrian-vehicle-interface/struck-by, surface-and-grade/stability, and lighting-and-layout hazards and assigns the pedestrian, surface, and lighting controls that hold up in the field.
Why temporary parking areas needs its own AHA
Temporary parking areas establish, arrange, and maintain the temporary parking for the construction workforce and visitors — the graded, surfaced parking areas and the pedestrian routes from parking to the site. The defining feature is that parking areas are where large numbers of workers move between their vehicles and the site on foot, creating a pedestrian-vehicle interface, plus the parking surface and access. The hazards combine the pedestrian-vehicle-interface and struck-by (parking areas are where many workers move between vehicles and the site on foot, among moving/parking vehicles — the struck-by hazard at the pedestrian-vehicle interface, especially at shift changes when many people and vehicles move at once), the surface-and-grade and stability (the parking surface and grade — soft, uneven, sloped, or poorly drained parking surfaces create slip/trip (pedestrians) and vehicle (parking on slopes, soft ground) hazards), the lighting-and-layout (parking used in low light (early/late shifts) and the layout — inadequate lighting and poor layout create struck-by and trip/fall hazards), and the environmental. The pedestrian-vehicle-interface/struck-by and the surface-and-grade/ stability justify a dedicated AHA.
Breaking temporary parking areas into steps
The steps for a Temporary Parking Areas AHA follow the parking:
- Plan the parking layout and pedestrian routes
- Prepare the parking surface and grade
- Establish pedestrian routes from parking to site
- Provide lighting for low-light use
- Manage the shift-change pedestrian-vehicle flow
- Manage the pedestrian, surface, and lighting hazards
- Maintain the parking area
- Complete
Each step carries a hazard, and the pedestrian-vehicle-interface/struck-by, the surface-and-grade/stability, and the lighting-and-layout are where the most significant risks concentrate.
The hazards step by step
Pedestrian-vehicle-interface and struck-by
Parking areas are where many workers move between vehicles and the site on foot, among moving/parking vehicles — the struck-by hazard at the pedestrian-vehicle interface, especially at shift changes when many people and vehicles move at once. The controls are defined pedestrian routes from parking to the site (separated from vehicle movement), controlled pedestrian-vehicle interaction (crossings, separation), high-visibility PPE, managing the shift-change flow (the peak interface), and the pedestrian-interface controls. The pedestrian-vehicle-interface/struck-by is the primary defining hazard — parking is a high pedestrian-vehicle interface, peaking at shift change. (These follow the pedestrian-vehicle-separation fundamentals.)
Surface-and-grade and stability
The parking surface and grade — soft, uneven, sloped, or poorly drained parking surfaces create slip/trip (pedestrians) and vehicle (parking on slopes, soft ground) hazards. The controls are an adequate parking surface (stable, reasonably level, drained), managing slopes (safe parking grades, wheel chocks where needed on slopes), slip/trip control on the pedestrian surfaces, and the surface/grade controls. The surface-and-grade/stability is a defining hazard. (These follow the walking-working-surface fundamentals.)
Lighting-and-layout
Parking used in low light (early/late shifts) and the layout — inadequate lighting and poor layout create struck-by and trip/fall hazards. The controls are adequate parking-area lighting (for low-light shift use — lighting is a safety function here), a clear parking layout (defined spaces, aisles, pedestrian routes), signage, and the lighting/layout controls. The lighting-and-layout is a defining hazard — parking is used in the dark at shift changes. (These follow the illumination fundamentals.)
Environmental
The environmental (weather affecting the parking surface and conditions) carries the environmental hazard. The controls are managing weather effects (mud, ice, snow on the parking/pedestrian surfaces), and the environmental controls. (These follow the environmental fundamentals.)

| Maintain | Surface / weather | Maintain the parking area, manage weather | project |
Pedestrian-vehicle separation and surface/lighting safety
A Temporary Parking Areas AHA centers on pedestrian-vehicle separation and surface/lighting safety. The pedestrian-vehicle separation addresses the interface where workers move between vehicles and the site — controlled by defined pedestrian routes from parking to the site (separated from vehicle movement), controlled crossings, high-visibility PPE, and managing the shift-change flow (the peak interface). The surface/lighting safety addresses the parking surface and low-light use — controlled by an adequate parking surface (stable, level, drained), managing slopes, slip/trip control, and adequate parking-area lighting for low-light shift use. And the environment gets weather controls. An AHA built on pedestrian-vehicle separation and surface/lighting safety, with environmental controls, addresses the hazards that define temporary parking areas.
From the field: what actually goes wrong
In fourteen years across federal, heavy civil, and industrial projects, temporary parking areas concentrate a specific version of the pedestrian-vehicle hazard: they are where the entire workforce moves between their vehicles and the site, on foot, among vehicles, and it all peaks at shift change. The pedestrian-vehicle- interface and struck-by hazard is the primary concern — parking areas are where many workers move between their vehicles and the site on foot, among moving and parking vehicles, so there is a struck-by hazard at the pedestrian-vehicle interface, and it is especially acute at shift changes, when large numbers of people and vehicles move at the same time (everyone arriving or leaving at once). So defined pedestrian routes from the parking to the site (physically separated from vehicle movement), controlled pedestrian-vehicle interaction (crossings and separation), high-visibility PPE, and specifically managing the shift-change flow (the peak interface, when the risk is highest) are the controls. The shift-change surge is the defining hazard moment for parking areas.
The surface-and-grade/stability and the lighting-and-layout are the other defining hazards. On the projects I have run, temporary parking surfaces are often graded ground rather than paved lots, so soft, uneven, sloped, or poorly drained parking surfaces create slip and trip hazards for the pedestrians and vehicle hazards (parking on slopes or soft ground) — controlled by an adequate parking surface (stable, reasonably level, drained), managing slopes (safe grades, wheel chocks where needed), and slip/trip control. The lighting-and-layout hazard is important because parking is used in low light — early morning and late evening shifts mean workers park and walk in the dark, so inadequate lighting creates struck-by and trip/fall hazards, making adequate parking-area lighting a genuine safety function (as with temporary lighting generally), along with a clear layout with defined spaces, aisles, and pedestrian routes. The environmental effects (mud, ice, snow) round it out. The AHA built on pedestrian-vehicle separation and surface/lighting safety is the one that protects the workforce in the parking areas.
The bottom line
A Temporary Parking Areas AHA names the pedestrian-vehicle-interface/struck-by, the surface-and-grade/stability, and the lighting-and-layout hazards with specific controls — defined pedestrian routes separated from vehicles with shift-change flow management (the peak interface), an adequate stable parking surface with slope management, and adequate lighting for low-light shift use. The pedestrian-vehicle separation and the surface/ lighting safety are the defining concerns. The AHA that manages both is the one that protects the workforce.
Frequently asked questions
Why is shift change the peak hazard for parking areas?
Parking areas are where the entire workforce moves between vehicles and the site on foot among vehicles, and at shift changes large numbers of people and vehicles move at the same time (everyone arriving or leaving at once) — making the pedestrian-vehicle struck-by hazard especially acute. Controls are defined pedestrian routes from parking to the site (separated from vehicle movement), controlled pedestrian-vehicle interaction (crossings, separation), high-visibility PPE, managing the shift-change flow (the peak interface), and the pedestrian-interface controls.
Why does parking-area lighting matter?
Parking is used in low light — early morning and late evening shifts mean workers park and walk in the dark, so inadequate lighting creates struck-by and trip/fall hazards, making adequate lighting a genuine safety function. Controls are adequate parking-area lighting (for low-light shift use), a clear parking layout (defined spaces, aisles, pedestrian routes), signage, and the lighting/layout controls.
What surface and grade hazards apply?
Temporary parking surfaces are often graded ground rather than paved lots, so soft, uneven, sloped, or poorly drained surfaces create slip/trip hazards for pedestrians and vehicle hazards (parking on slopes or soft ground). Controls are an adequate parking surface (stable, reasonably level, drained), managing slopes (safe grades, wheel chocks where needed), slip/trip control on the pedestrian surfaces, and the surface/grade controls.
What are temporary parking areas?
Temporary parking areas establish, arrange, and maintain the temporary parking for the construction workforce and visitors — the graded, surfaced parking areas and the pedestrian routes from parking to the site. Because they are a high pedestrian-vehicle interface (peaking at shift change) with surface/grade and low-light considerations, the pedestrian-interface, surface, and lighting hazards apply.
