Early yesterday
morning, asilo year-old man was killed when he fell
into an open manhole outside his house. The manhole was opened
by the local authority so that old cables could be removed. Today
the
investigation into the incident is being carried out by the police. They
have already said that the manhole should have been covered by the
two construction workers to keep the site safe and that the two men
have been charged with causing death by negligence.

Answer:
Manhole covers are often made out of cast iron, concrete or a combination of the two. This makes them inexpensive, strong, and heavy, usually weighing more than 113 kilograms (249 lb). The weight helps to keep them in place when traffic passes over them, and makes it difficult for unauthorized people without suitable tools to remove them.
Manhole covers may also be made from glass-reinforced plastic or other composite material (especially in Europe, or where cover theft is of concern). Because of law restricting acceptable manual handling weights, Europe has seen a move towards lighter weight composite manhole cover materials, which also have the benefits of greater slip resistance and electrical insulating properties.
A manhole cover sits on a metal base, with a smaller inset rim which fits the cover. The base and cover are sometimes called "castings", because they are usually made by a casting process, typically sand-casting techniques.[1]
