Keystone Hardware $($KH$)$ is a busy hardware store located in a retail park, open $7$ days a week. The store employs $80$ workers, including three managers: the store manager $($SM$),$ the building materials manager, and the garden manager. The store is divided into public areas, including a large sales floor, two outdoor areas, a caf$,$ and customer toilets, and worker$-$only areas, such as a warehouse, offices, worker toilets, a rest area, and two greenhouses. The store offers a wide range of products and services, including a woodcutting service using a vertical panel saw $($VPS$).$ The VPS is located at the back of the store, between two sets of automatic sliding doors, and is operated by five trained workers who alternate the task. Worker X always volunteers to operate the VPS when working, while Worker Y also enjoys the task but often experiences respiratory issues. The SM has concerns about wood dust exposure and noise levels associated with the VPS$,$ prompted by an article in a trade magazine.

The warehouse and delivery area are well$-$organized, with clearly marked pedestrian walkways and well$-$maintained equipment, including two forklift trucks and ten pallet trucks. The delivery area is limited in size and accommodates vehicles ranging from small vans to large trucks. The offices, accessible from the delivery area, access road, and outdoor area $1,$ house the managers' desks and the Human Resources and Accounts departments. Outdoor area $1$ features the Gardens and Landscaping department, with gravelled pathways, paved areas, and two greenhouses. The area sells plants, shrubs, garden ornaments, plant foods, and pesticides. Some of the paving around the greenhouses is uneven, and some lighting is no longer working. The caf$$ is always busy, with tall screens surrounding the seating area to shield customers from cold air but causing workers to feel too warm. Workers use hand$-$held trays to serve food and drinks, which can be heavy and slippery, leading to incidents of dropped items. Outdoor area $2$ houses the Building Materials department, with cracked and broken concrete floors due to vehicle and forklift use. Pallets of materials are positioned close to one another around the perimeter of the area.Outline manual handling risks arising from the work environment at KH$.(21)$
