Task $6$: Maintenance activities in the garage $6$ What is unsatisfactory about how the maintenance activities are carried out in the garage? $(25)$ Note: You should support your answer, where applicable, using relevant information from the scenario.

Next to the storage facility is a brick$-$built garage that is accessed through a large roller$-$shutter door. This door is regularly kept closed, especially when the weather is cold. The garage is used to store and maintain all maintenance vehicles, such as a $4-$wheel$-$drive tractor, three ride$-$on grass cutting machines and four small all$-$terrain vehicles. The vehicles are regularly moved around in the garage. The vehicle maintenance work carried out is simple and limited to cleaning, minor repairs, and monitoring. Older maintenance vehicles are often left unattended with engines running to warm them up before use. These vehicles sometimes cause an obstruction in the garage.

There is an inspection pit in the garage. The steps down to the pit are worn and slippery, and workers have noticed mouse faeces in the area. The garage is heated by steam$-$heated radiators. One propane space heater is available to use in colder months; LPG canisters from the storage facility are used to fuel this. On one occasion, when replacing a used canister, an empty canister was accidentally retrieved from the storage area.

There is a maintenance schedule designed to reduce simultaneous vehicle work. However, on many occasions three or four maintenance activities have been carried out at the same time. The schedule is displayed on the left$-$hand wall by the roller shutters, above the garage inspection sheet. The garage inspection sheet was last signed and dated three weeks ago.

Workers often use the garage as a shelter for smoking and breaks. On one of these occasions, a discarded cigarette ignited some waste. A worker tried to raise the alarm by shouting, but could not be heard over the radio that was switched on$.$ They went to retrieve a fire extinguisher from the clubhouse and extinguished the fire alone.

In the garage, a vehicle was driven over the inspection pit for an oil change. However, visibility was poor due to some of the lights in the garage not working. A new worker, who wanted to make a good impression, decided to change the vehicle$$s oil after watching an online video. They stepped down into the inspection pit and began to remove used oil and replace the oil filter. During the activity, engine oil spilled onto their arms, chest, and legs. Shouting for help, they began to clean up the spilled oil with rags. No one heard the worker. Once the task was finished, the worker complained of dizziness and a sore throat. They threw the oily rags into the garage waste bin. They did not have any spare clothing, but they refused to return home to get changed.
