Once this is done, you’ll know the kind of measures you need to take, from building with fire rated drywall, installing fire extinguishers or other passive fire stopping products, installing or upgrading doors to fire doors, choosing the appropriate fire retardant to making sure you have fire retardant curtains, furnishings and fabrics protected.
