I wouldn t worry about a attic hatch in a garage if its not heated.
Attic hatch material in garage.
Attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents.
Exspecially in winter when the exhaust is visible.
Just because you have your garage door open doesnt mean the exhaust will automatically leave the space.
Missing or opened covers should be called out as should covers made from flammable materials such as thin plywood.
In garages that have access to the attic a hatch cover made from an approved fire rated material should protect this access at all times.
